Titan Solar Generator vs Delta Pro Power Station

For many years the Titan has been unrivaled as the best solar generator available. It is in the homes of thousands of people helping to back up their emergency essentials with ease. But is there a new “kit” on the block with the Delta Pro power station? It has very similar features to the Titan with some minor and some major differences. In this review we’ll see exactly what those small and big differences are so it’s easy for you to know if either of these units is the one you want.

In the end, both systems are very good and anyone who has one or the other will be pretty well set when it comes to backup power for running fridges, freezers, medical equipment, lights, fans, kitchen appliances, tools, and more. But for some people, they may need that one little difference that one unit has and the other one doesn’t.

What Can They Power?

There are multiple things to consider when it comes to the output capacity of solar generators. Both the Titan and the Delta Pro have pure sine wave inverters that are very powerful. Before the Titan was launched in August of 2019 there was basically no other solar generator that had a powerful inverter, and the Titan fixed that. But when the Delta Pro launched in the winter of 2021, it surpassed the Titans inverter by just a little bit.

The Titan’s inverter is 3,000w output and a 6,000w peak. The Delta Pros inverter is 3,600w output and 7,200w peak. The real question is, will 3,000w be enough for everything you need to run and if it is, then wouldn’t 3,600w output be overkill and unnecessary?

Having been in the solar generator industry since its inception and having talked with literally tens of thousands of people about solar generators, I have never once met anyone that said that 3,000w of continuous output was not enough for their needs.

But what are people’s most common needs? Typically to run one or two fridges, one or two freezers, TV, Wi-Fi, a few lights, a fan or two, chargers for mobile devices, and often times medical equipment. More than 90% of people are running those types of items. So in that case, the Titan would be enough, and so would the Delta Pro since they both can run all of that with no problem.How long does a well pump last? | CroppMetcalfe

But the one item that is often mentioned and is a very important item, is the well pump. Many people are looking to run water into their houses with ease when the power is out. This is where the Titan is not capable of running because the vast majority of well pumps are 240v power and the Titan can only do 120v power. Whereas the Delta Pro is capable of running 240v power as long as you have two Delta Pros and the 240v connection hub.

As long as the well pump doesn’t use more than 240v and 30a to run continuously, then the Delta Pro can easily run it. Most well pumps use 240v and 5a to 10a to run continuously depending on their size. The next big issue is how do you connect the Delta Pros to your well pump since it’s hard-wired into the house? In that case, you either need the EcoFlow Smart Home Panel, or your own transfer switch and adapters to connect to the 240v connection hub. But if you do that, then you can run your well pump.

Which solar generator is better, the Titan or the Delta Pro? The answer is “it depends.” Do you absolutely need 240v power? Then you need the Delta Pro. If you don’t need 240v power, then likely the Titan is a better option since it can expand to higher battery capacity and has a better solar input. But let’s define those parameters as well.

Battery Capacity

To be very clear, the battery capacity that you need is specific to you. Everyone’s needs differ from each other. One person may only need 2,000wh to get through a night of just running their fridge and charging their phone. Someone else may need 10,000wh because they have a medical condition and have to run a window unit A/C all night and all day non-stop. Either way, both systems have large battery expansion capabilities but that also comes at a price.

Battery 3D Illustrations Designs, Images, Vectors, HD GraphicsThe Titan is really two pieces put together into one unit. The top section, referred to as the “power module,” contains an inverter, two charge controllers, step up and step down voltage devices, safety measures, fans, and so on. The power module is the brain of the whole system. In order for it to operate appropriately, it needs a heart, which is the battery. A Titan is one power module combined with at least one Titan battery. Technically speaking the Titan is capable of having up to 135 Titan batteries attached to it, but obviously, no one would do that.

But one unique feature of the Titan, that no other solar generator anywhere has, is the ability to use non-Titan branded batteries. The external batteries must be 24v and it is only recommended to use lithium-type batteries, but even still, that’s a very unique feature. Also, the Titan was the first solar generator to incorporate stackable batteries that link together to share their energy. The Titan batteries are Lithium NMC with 2,000 cycles (plenty for anyone).

The Delta Pro, on the other hand, must use EcoFlow proprietary expansion batteries, and each Delta Pro can have a maximum of two expansion batteries. Each battery is 3,600wh which is plenty of energy storage. At a maximum, there can be two Delta Pros linked together, and have a total of four batteries between the two units, for a max battery capacity of 21,600wh.

Which solar generator is better? Well again, it depends. Do you need or want the ability to use non-brand-specific batteries to add to your system in an emergency? Or do you love the stacking ability of the batteries to seamlessly join together? Then the Titan is the best option. Or do you want longer lifecycles on the Delta Pro batteries but be limited to how many batteries can be joined together and have all of the modern technology for monitoring them and auto-balancing them? Then the Delta Pro is the best. Once again, it depends on your preferences and needs for what you want to do with the power stations.


In the end, a solar generator, just like a gas generator, is only good if it has enough fuel to run all of your equipment. This includes charging from solar panels as well as recharging from the wall at home or from a gas generator when the grid is down, and the weather is bad.

The Titan comes with a standard wall charging brick that is capable of charging at about 350w. With that standard charger alone, it takes about 6 hours to recharge a single Titan battery from 0% up to 100%. But it is also easy to upgrade that wall charging brick to a fast charger that charges at about 650w which brings down the charge time for a single battery to about 3 hours. And the Titan can use up to two wall chargers at the same time, so the fastest charge speed is about 1,300w which can charge a single battery in less than 2 hours. But to get those fast wall chargers do cost extra.The History and Definition of Solar Cells

The Delta Pro has a very simple wall charging cable that does not have a large power adapter brick on it. This keeps the charging cables light, small, and easy to store because it’s just a cable, nothing else. On the back of the Delta Pro where the charging ports are, there is a small toggle that allows the user to switch between slow charging and fast charging. Slow charging speed is about 300w and fast charging is about 1800w. That means on slow it will take about 12 hours to charge and on fast only about 2 hours to charge from a wall outlet. And the charge speed can be customized within the phone app for both settings. There is no extra fee for fast charging, it is free and built into the Delta Pro.

In terms of charging from a wall outlet, the Delta Pro definitely wins. But is it the best option for off-grid charging from solar panels?

The Titan has the largest solar input capability among these two units. It has two MPPT charge controllers and each one will let in 1,000w at a time. This gives the Titan 2,000w of solar input which is very impressive. One of the best features of the Titan is it can easily be over-paneled, meaning it can have more than 2,000w of solar panels connected. The charge parameter is 35-145v and 30a per charge controller.

Why is over-paneling such a good thing? In the USA there are an average of five solar peak hours per day. That means for five hours a day the solar panels will make their max solar output. Usually from about 10am to 3pm. If you have 2,000w of solar panels connected, you can make about 10,000wh of energy in those five hours. But if you are over-paneled, then you will begin making the max solar input earlier in the morning and later into the afternoon. This allows you to have anywhere from 6 to 10 solar peak hours per day depending on the time of the year and how many solar panels you connect.

A single Delta Pro can input up to 1,600w from solar through its single MPPT charge controller. The charge parameter is 11-150v and 15a. Because the amps are much lower than the 30a on the Titan it is much harder to over-panel the Delta Pro. It is still possible, but the best-case scenario with our 200w solar panels we have seen that the Delta Pro can over-panel up to 2,400w per unit. You can get twice the solar input with another Delta Pro, but then you have twice as much battery to recharge, so it doesn’t really increase the recharge speed.

In terms of having a single solar generator, Titan definitely wins the solar charging portion of this comparison. But if you have two Delta Pros, you can technically exceed the Titan’s recharge rate but also can’t over-panel as much as you can with the Titan.

Final Thoughts

Which unit is best? I think they are pretty much equal. The only big advantage the Delta Pro has over the Titan is the ability to put two units together and make 240v power. The Delta Pro’s more powerful inverter is a very small win over the Titan since the vast majority of people never go over 3,000w of continuous draw off of their inverter. The Titan has better battery expandability than the Delta Pro and doesn’t even require proprietary batteries which is a massive win over the Delta Pro. As far as solar goes, they’re nearly the same solar input with the Titan beating the Delta Pro when compared to a single Delta Pro unit.

As far as customer service goes, they’re pretty much equal. If you purchase either unit from Powered Portable Solar then you’re given extra customer service and support by Americans located here in the USA who know the ins and outs of these systems and what will work best for your situation. If you need additional help deciding which unit is best for your situation, contact us and we’ll be happy to help.

Personally, I have two Titans, and I have two Delta Pros, I like both models a lot. One Titan runs my off-grid cabin 100% of the time year-round, the other runs my RV on long trips with my family, and even runs our A/C unit with no problem. My two Delta Pros are set up in a 240v configuration at home for when the grid power goes out, and I run my whole house with no problem. They each serve their purpose and I have been very pleased with purchasing both of them.

In the end, only you can truly decide what is best for you, but we’re always here to help too.

Titan Solar Generator 1 Year Review

It’s no secret that I helped design the Titan solar generator. I worked with the owners of Point Zero Energy to bring to market the absolute best solar generator that has ever been made.

You may say that I have a biased opinion. But truly I don’t. If something else comes out that’s better, then that is what I will recommend to people. The fact is, the Titan has been out for well over a year, and even the largest solar generator companies such as Goal Zero, MAXOAK, Ecoflow, Inergy, Renogy, and so on have not produced anything better.

In fact, most of those companies have all come out with new solar generator models in the last 6 to 12 months, well after the Titan had been released, and still, they haven’t beaten the Titan.

Take a look at this video and article that shows an apples-to-apples comparison between the Top 8 Solar Generators:

Keep in mind, that even though I helped design the Titan with the owners of Point Zero and have known them for many years, I own 0% of the company, am not on the payroll in any way, shape, or form, and even had to purchase my two Titan solar generators for myself. I have received ZERO compensation from Point Zero for my consultation, designs, or input. And I am perfectly okay with that.

To be clear, I am not complaining. I wanted to help bring to market the best system ever, and I am proud that I was able to be a part of that. What I am saying is that I do not have a biased opinion since I have had to pay thousands upon thousands of dollars for my own Titan equipment.

Off-Grid Cabin

How has the Titan solar generator been over a full year? I literally had the first unit and have been using it for well over a year. Shortly after receiving my first Titan, I bought our off-grid family cabin that needed a little bit of work in regard to electricity.

When I bought the cabin it actually had an old Inergy Kodiak as the “off-grid” setup. It came with solar panels to charge the Kodiak and the extra batteries but to no surprise, the Kodiak and extra batteries were long dead. I like the Kodiak, but the batteries actually impede the capability of the Kodiak. Not to mention that the cables from the solar panels had fried because Inergy was a little misleading in how to set up solar panels on the Kodiak and other systems they have made. That’s one reason I don’t recommend or use their equipment anymore.

I needed a serious power solution that could replace the existing solar equipment. Obviously, the Titan was my choice because it has a 3,000w inverter which is powerful enough to run everything in that cabin all at the same time. Also, since the Titan has very easy-to-use expandable batteries I knew I wouldn’t have any complicated wiring setups with external batteries.

I was able to take the existing solar panels that were up at the off-grid cabin and connect them with some other salvaged solar panels to make more power for the Titan and the cabin. It worked very well for our basic needs. Running lights, fan, full-sized fridge, TV, electronics, chargers, and so on.

The thing that surprised me the most was how much electricity our propane gas oven used. What never occurred to me is that the oven didn’t have a pilot light as a gas stove would. It uses an electric igniter that gets glowing red hot in order to ignite the propane to heat the oven. The igniter is not always on when the oven is baking/heating but it turns on and off periodically. The igniter alone uses about 700 or more watts to run. That’s quite a high amount of power to run a little igniter.

I wanted the off-grid cabin to not only be a fun and enjoyable place for my family but also a potential bugout location in case of a severe emergency. That means it needed to be ready for long-term living.

That is why I upgraded the solar panel array and added more batteries to my Titan solar generator. I had a total of 3 Titan batteries and 4,000w of solar panels.

We have let many people stay at the cabin in an effort to figure out all the different issues that we didn’t know about so we could work on them and get them fixed for long-term living.

We found we had septic issues, water line issues, propane issues (nothing dangerous), and other small quirks. But one issue that never came up, was the Titan. With 6,000wh of battery, it is equivalent to 2-4 days of stored power depending on what is being used and how the power is rationed. Essentially, if the sun didn’t shine for 3 days and we rationed the power, we could last all the 3 days running the bare essentials.

But, because I installed 4,000w of solar panels I increased our solar peak hours from about 5 hours a day to about 8 to 10 hours a day depending on the time of year. That means, rather than being able to only make up to 10,000wh of power per day, I can make upwards of 16,000 – 20,000wh of power by having the Titan “over-paneled.”

Over-paneling just means having more panel wattage connected to a system than what that system can let it. The Titan can only let in 2,000w of power, but because I have 4,000w connected it is over-paneled.

If I had 2,000w of panels connected, at 9 am I could be making about 1,000w since the sun isn’t very high up in the sky yet. But with 4,000w of panels connected, at 9 am I’m making twice as much power as I would with only 2,000w in panels connected. That means by 9 am, I’m making 2,000w and don’t have to wait until 11 am to make 2,000w like I would if I only had 2,000w in panels.

This is why I have the Titan++ 4,000 Rigid Kit available for people to get because I have run this setup for a very long time. I know firsthand that this is truly an extremely powerful kit for long-term power outages.

It doesn’t matter if it’s a blackout in California from high winds, a hurricane in Florida, a winter storm in Texas, a blizzard in Idaho, a tornado in Missouri, flooding in Louisiana, or any other natural disaster or emergency. The Titan is truly the absolute best solar generator option. These disasters are not going away. Every year these disasters repeat themselves in different ways in different locations. If anything, they are getting more common and worse.

Since installing the Titan++ 4000 kit at my off-grid cabin, I have never lost power. The Titan has been running my family off-grid cabin without stopping. That is an amazing track record.

Our First Power Outage

I did mention I have two Titan solar generators. One is permanently installed at my family’s off-grid cabin. The second, which I also paid for, I keep at my house in case of a power outage.

You may be asking why I don’t have solar on my house if I am so into solar generators and solar panels. To be blunt, my electric bill is an average of $50 per month. Going off-grid at my house costs tens of thousands of dollars and so my cost savings would take decades to recuperate.

The last solar big I got was about $32,000 and that did not include a ton of extra batteries to account for multiple days of bad weather. $32,000 ÷ $50 = 640 months before I break even. That’s 53 years! I’ll be 84 by then!

If my electricity bill were $400 a month then it would make a lot of sense to go off-grid or supplement my bill because that would be made back in 6 or 7 years.

I don’t have to worry about going off-grid though because I have my Titan at home. I have over 3,000w of panels at home as well as 2 batteries on my Titan. I have found that for my at-home power needs that’s enough to run my essentials for a couple of days even if there is bad weather. Typically, because I have so many solar panels, even on semi-cloudy days I can make a little bit of power and help keep my batteries at the same percentage all day or even get a small charge.

If it’s a clear sunny day after a power outage then the entire system is recharged within a few hours tops.

The first power outage we had after getting the Titan was very interesting. When the power went out we had no idea how long it was going to last, as with most blackouts. I waited about 1 hour before getting my Titan out because I didn’t want to set it up and run extension cords everywhere if I didn’t have to.

After 1 hour of no power, I set up the Titan. I ran the extension cords. I connected the fridge, freezer, multiple lights, TV, chargers, and so on. It was spring so it wasn’t hot or cold out so we didn’t have to worry about A/C or heat.

It also happened after the sun had gone down, which meant I couldn’t set up my solar panels to help supplement my power needs. This is why I stress getting a second battery or more for people. Having more batteries makes it much easier to get through the night without running out of power.

My family and I went to bed comfortably knowing that we had plenty of power to run our essentials for however long we needed during the blackout. Luckily, the next morning the power came back on. But we ran all that we needed, plus watched a movie that night as a family, and didn’t drain the battery.

It was comforting knowing that if the power wasn’t back on in the morning I could simply set up the solar panels and we’d be fully charged within a few hours while still running the fridge, freezer, and other essentials.

Since then, I have had a transfer switch installed so that I can simply plug my Titan into the transfer switch and run certain parts of my house without needing extension cords. This must be done by a licensed electrician and you need a 30amp 3 prong plug installed that you connect to from the Titan to power a sub-panel that runs certain circuits in the house.

1 Year Review

Since getting my Titans, I have gone through multiple power outages. I have run my off-grid cabin non-stop. I have been able to help others run essential equipment as well including CPAPs, oxygenators, and other medical equipment that helped people during blackouts. That would not have been possible without the power, expandability, and portability of the Titan.

Click Here for the Best Titan Kits

Not only that, but I also enjoy being able to grab my Titan, take it out to my RV, plug the shoreline power cord into the Titan and run my entire RV as if I was at a campsite. I have 2,100w of solar panels installed on the roof of my RV. It is very easy to boondock with my Titan and RV because the Titan is strong enough to run everything, has enough panels to recharge quickly, and a large enough battery to run all of my evening and nighttime equipment without any issues. We can stay in locations for as long as we want and have the power we need.

The Titan is truly the most powerful solar generator that has ever come out so far. It is incredible to be a part of a legacy of redefining the solar generator world.

If you want to have the same protection as I do when it comes to preparing for emergencies, disasters, and long-term power outages then I highly recommend you take a look at the Titan solar generator. It truly is unmatched and has been unmatched for quite some time. My yearlong testing and reviewing have come to prove that it can do whatever I need during those hard times.

Titan Solar Generator – The Best of its Kind, Period


I have been involved in emergency preparedness for my entire life. I have grown up doing it and truly believe at some point we will all face a moment when being prepared for an emergency would’ve drastically made life 100x easier.

It doesn’t matter if it’s an earthquake, hurricane, flooding, tornado, winter storm, power outage, EMP attack, or any other kind of emergency, having power is a necessity. There are a number of different solar generators out there.

I have been working in the solar generator niche for a number of years now and have tested, played with, compared and evaluated many solar generators. Finally, Point Zero has taken essentially years worth of info and requests from customers and people interested and compiled it into one solar generator, The Titan.

Here is a pre-release video that I was able to make during the production of the Titan. Even as a prototype it’s amazing. A full detailed review will come out soon with the final production unit. But it will essentially look like what you see in the video with a minor change in the screen.

As mentioned in another post there are 11 tips or points for finding the best solar generator. They are:

Areas to Consider

All of these points are vital in determining which unit to go with. Everyone has different needs so that’s another thing to take into account. That being said, the last few years I have been working with hundreds of customers using different solar generators and have heard what most people really want. This is the reason why I like the Titan so much is that it fulfills all those desires of users.

Below I have shown how the Titan Solar Generator measures up against the top 6 competing solar generators in each category mentioned above. A full detailed comparison follows. I also have a more extensive comparison chart with the top 17 solar generators available that you can view through the button below.



1. Battery Capacity

The Titan has a 2,000 watt-hour lithium-ion battery that is extremely powerful and light for its capability. The original model of the Titan solar generator had an 1,800 watt battery. Point Zero was able to put in a 2,000 watt battery that was lighter than the 1,800 watt battery which is incredible. The battery is actually rated for more than 2,000wh but it is called a 2,000wh battery because you can for sure use all 2,000wh in it. Other manufacturers will advertise their “nominal” wattage which is actually higher than what you can get out of it. However, with the Titan they are advertising the usable watt-hours.

Most lithium solar generators can only use a max 90% of the total battery capacity. So for example, if a generator had an 1,100wh battery, only 90% (990 watts) would actually usable. The Titan’s battery though has a full 97% usable capacity, or rather, 2,000wh of usable power.

If it had the same efficiency as other solar generators it would only have 1,800wh usable. Since Point Zero worked really hard to get the highest quality battery it means that for all intended purposes the entire battery can be used.

It is important to know that lithium-ion batteries can be damaged and will not have as many life cycles if they are charged too fast. Generally, this number is around 2 hours from 0% to 100%. So if the battery were drained to dead, 0%, and 2,000 watts of panels were connected and charged the unit in 1 hour, it would end up damaging the battery. This is why the Titan is built with a 1,000-watt solar panel charge rate. That means it cannot be charged in less than 2 hours which means the battery never gets damaged and keeps its life cycles longer. Very cool.

2. Weight/Portability

This is the toughest part of the Titan, the weight. We have been spoiled with the Kodiak since it only weighed 20lbs. That 20lbs was amazing and the Kodiak was amazing for what it could do, being that lightweight. However, there were many things it’s couldn’t do. The new Apex which replaced the Kodiak now weighs 25lbs because it has some slightly changed features. The Titan though is right in about 65lbs.

65lbs is A LOT of weight to handle. When Point Zero first told me it was going to be 65lbs I was not excited. They invited me to meet with them and see the prototype unit they had made which was really nice of them. I went and saw it expecting this huge box that I wouldn’t be able to move easily. Once I arrived and saw the new unit I noticed 4 clasps around the side, the Titan is two separate pieces!

The top part which holds the plugs, 3,000w inverter, 2 MPPT controllers and all the brains separates from the bottom battery piece! This was incredible. I had heard of designs like this but had not seen anyone actually pull it off. The Titan, when split into two pieces, has two 33lb pieces which are very easy to move around. Each piece is only slightly more than the Apex.

As I got to test the prototype Titan unit it was very easy to move around once it was split into two pieces. It is very easy to put back together and there’s no way to put it back together incorrectly. It is 100% foolproof.

I loved that Point Zero did that because it allows the unit to still be very portable and moveable in emergency situations. Simply disconnect the top from the bottom, then move each piece individually or in each hand and move it to wherever it needs to go.

Going back to the point of the battery capacity, since it can be separated that means that more batteries can be sandwiched in between the top and bottom piece which increases its “fuel tank” capacity.

Once a second battery has been added, the unit will have 4,000wh of power. At that point, the Titan will actually automatically allow up to 2,000 watts in solar panels to put on, instead of just 1,000 watts. The Titan has two charge ports and each one easily handles 1,000 watts of solar power. This means once I put more than 1,000 watts of panels on the Titan I simply plug them into the second port.

3. Charge Speed

This is the hardest part for me when it comes to seeing different solar units on the market. Many of them such as the Goal Zero and Humless have decent battery sizes but can’t be charged quickly.

For example, the Goal Zero 1400 Lithium takes 4.5 hours to charge with its MAXIMUM amount of solar panels connected. That’s under perfect conditions which are not common. So it barely meets the requirement to charge in 5 hours. If it’s a cloudy day or more power is needed then it is impossible to charge in that 5-hour time frame which means it can’t be charged in a day, that’s a no-go for me.

Same goes the Humless. It’s absolute fastest charge speed is 5.2 hours. Which means even on a bright sunny day it will barely charge in one day and that’s only if conditions are perfect and I’m not using it during the day to run other equipment.

Around the USA there is an average of 5 to 6 hours of light a day where solar panels can make their maximum power. This varies from Summer to Winter but 5 to 6 hours is commonly agreed on. So, for example, the Flexible 100w panels are 100-watt monocrystalline solar panels. They are the best I have been able to find and are extremely rugged. But each day, under ideal Rich Solar Panelperfect conditions, they will only make a max of 100 watts each for 5 to 6 hours.

The time is usually averaged to 5 hours a day to account for different parts of the USA and time of year. So if I have 500 watts in solar panels I can count on making around 500 watts in panels x 5 hours of light = 2,500 watts generated on bright sunny days.

This means that a Titan that has 500 watts in panels can be charged in about 4 hours from zero to full. That is a perfect setup for emergency power needs running very basic equipment. Or even for RVs and Vans it’s enough power to run essentials and still charge up during the day.

It is even better if the Titan has 1,000 watts in panels because it can be charged in about 2 hours. Even with only 400 watt in panels it will charge in the minimum requirement of 5 hours from 0% back to full 100%. That is not recommended to have that low of panels though because normally I would still need to be running some equipment during the day such as a fridge, chargers or fans. So I still need my panels to make enough power to be charging the battery while still running equipment.

The Titan is able to run equipment while being charged by solar panels, wall outlet, car charger or whatever power source. If I know my battery is at 50% because I used it all night and I need to charge it during the day while running equipment then I need my panel array to be big enough to handle the charge and usage. For example, my battery is at 50% (1,000wh) and I have 500 watts in panels. I know I need to run 250 watts worth of equipment during the day. So if my panels are making 500 watts of power, then 250 watts of that will go to the equipment and the other 250 watts will go to the battery. 250 watts/hr x 4hrs = 1,000wh into the battery in 4 hours. Perfect! I’m golden, I can run my stuff and be charged by dinner time for the night.

Another great feature about the Titan is that the wall charger that comes with it is already a fast charger! With other units, I was required to purchase an additional charger that would get extremely hot and still was only sort of fast. The Titan’s wall charger charges at a rate of 750 watts per hour. So if the Titan were empty it would only take less than 3 hours to charge it back to 100%.

But wait, there’s more! Not only is the AC Wall Charger a fast charger at 750 watts, but the Titan can accept two chargers! When a second battery or more is added to the Titan, a second AC Wall Charger can be added to double the charge speed. So if I have two batteries, 4,000wh, and I double the AC charging speed to 1500 watts then I can still charge it from 0 to 100 in 3 hours.

I don’t know that I would personally want a second charger just for the fact that 750w from a wall charger is already 3x faster than any other solar generator charger on the market. I don’t necessarily always need it to charge super duper fast. It would definitely be nice to have a second one just in case I do need to charge it really fast though, as a backup too.

The charger also has a built-in fan to keep it cool. All the others I’ve used don’t have a fan built into the box on the cord and so it gets crazy hot, to the point I can’t touch it. With the Titan AC Wall Charger it doesn’t get hot though.

This fast charge speed is nice for short term power outages that only last a day or two. With such a large battery I don’t even have to plug in my panels. When the power kicks back on I just charge it back up quickly.

4. Expandability

In the past, it has been very hard to find units that could easily expand with more batteries. In reality, not system out there had an easy expansion option for batteries. Plus pretty much all of them suggest expanding with lead-acid batteries, not my favorite.

The problem of expanding with lead-acid type batteries is that they’re more expensive in the long run when compared to lithium-based batteries. On top of that, it is generally not recommended to drain more than 50% energy from lead-acid batteries and definitely never below 30% because it will damage the battery. Also not to mention that mixing a lithium battery and lead-acid battery is generally not very good. So really expandability with Lithium is best.

The Titan is expandable with lithium batteries and it’s way cheaper than buying a lithium-ion battery elsewhere. The Titan can also expand its solar panel capacity as previously stated. Once a second battery is added to the Titan I can go from 1,000 watts in panels to 2,000 watts in panels.

Titan with 3 BatteriesThe Titan can add as many Lithium Titan batteries as desired. Each battery is 2,000 watts. So if 2 batteries are added then it has a battery capacity of 3 x 2,000 = 6,000 watt-hours of power, that’s crazy big! I could run my necessities in my house for about 3 to 4 days no problem with that amount of power, and that’s not using any solar panels.

If I had 2,000 watts in panels combined with that large of a battery bank I could run my emergency essentials such as fridge, freezer, lights, fans, tv, cpap machine, small window A/C unit and other small items probably indefinitely.

So that’s the first way it’s expandable, batteries. The second way is that the solar panel capacity is also expandable. Earlier I mentioned that it’s not wise to charge a lithium battery from empty to full in less than 2 hours. That is why the Titan only allows for 1,000 watts of solar input power. However, once another battery is added the total battery capacity is at 4,000 watts.

So if I have 1,000 watts in panels, it will take about 4 hours to charge, still pretty good since I only have 5 hours a day where I know I can make max power. But if I wanted to keep my charge speed down to 2 hours then I am able to turn on an additional bank of 1,000 watts in solar panels on the Titan. There are two solar input plugs and each plug can handle 1,000 watts in panels for a total of 2,000 watts. The second solar charge plug will be able to be used once the second battery is added. This keeps my charge rate at 2 hours still and doesn’t damage the battery lifecycle.

Because its solar charge speed can be expanded to 2,000 watts I can effectively have 4 or 5 batteries total for about 8,000 to 10,000 watts of power and still charge it in one day, INCREDIBLE!

5. Life Cycle

Lithium batteries are capable of lasting at least 2,000 cycles if the quality is high enough and they are used wisely. So why not just use the highest quality right? That’s what the Titan has. I have seen other manufacturers use lower quality and or lower density Lithium-Ion battery cells and it still doesn’t even bring the price down, so why do it?

The Titan has all the features built into it to make sure that not only safety measures are met but that the battery doesn’t get overworked. Not overworking the battery makes sure it will last the 2,000 cycles fully.

This is one common question I get, “Can I replace the battery once the unit has reached that point?” In the past replacing the battery on a solar generator was not something that could be done on your own at home. It would’ve needed to be sent back to the manufacturer and replaced. This means it would be at the warehouse getting worked on so it’d be gone for a minimum of 2 weeks but probably up to 6 weeks.

The Titan is so easy, all that is necessary is the new battery. The old one clips off, the new one clips on, done. But even still after all those cycles, the battery is still rated to be about 75% to 80% efficient. So rather than being a 2,000wh battery, it would be more like a 1,600wh battery, still better than other generators.

It is important to understand though how hard it is to use all 2,000 cycles. A “cycle” is the process of draining the battery down to a certain amount and then back up. If 2,000 cycles were done on the Titan, one cycle per day, it would take 5.5 years to reach 2,000 cycles. So I’m not too worried about it needing to be replaced anytime soon. Even still, I can always just buy another battery and add it on by stacking it, super easy.

My experience has shown that I do not use all 100% of the battery each day. If I average 50% of a cycle each day that means the battery will last 11 years before needing to be replaced. In the worst-case scenarios of an EMP attack, the US Military has said it would take about 10 years to rebuild. So, in that worst-case scenario, that means the Titan battery would outlast that 10 years rebuild time!

There isn’t a unit out there that is easier to manage the battery and lifecycles than the Titan.

6. Number of Plugs

“A Christmas Story” Lighting the Tree

This is one thing that I love about the Titan, I can plug a lot of things into if I need to. Units of the past have had anywhere from 2 to 4 110/120v plugs (wall outlet plugs). This made it difficult to plug in my fridge, freezer, fans, lights, chargers, TV and so on because of the limitations. I was having to get power strips for single plugs which can easily trip the fuse since so much power is going through one plug. I don’t like feeling like Ralphy’s Dad in “A Christmas Story” where he plugs all the lights of the Christmas Tree into one outlet and sparks fly everywhere.

I find that on almost all solar generators out there, the plugs are way too close together. This made it hard to plug in multiple items, especially if the plug was a big boxy plug. For example, the Patriot 1500 solar generator is a well-known unit on the market. One of my biggest gripes with it is firstly it only has two 110/120v plugs on it but then they’re literally smashed together. Any plug that has a large box on it covers the other plug.

The Titan has a unique symmetrical looking face that makes it easy to plug a lot of things in at once, including big boxy plugs. Since all the DC plugs are up top and all the wall outlet type plugs are spaced along the middle everything has its own room. Even with my old Kodiak, I would have to use 1ft extension cables so I could plug everything into the front of it even though it had plenty of plugs.

The Titan has 6 110/120v wall outlet plugs. 4 DC plugs w/USB options including USB C. Of course, it has a 30amp RV plug because Point Zero listened to people and they all said they wanted an RV plug. The RV Plug is rated to 25 amps.

The Titan has run welders and electric heaters, both extremely high power items, all at once in its testing phase and never had to use the RV plug for an extra bump in power. Not only that, but it ran 3,000 watts non-stop for 40 minutes! That’s not recommended though. Other units on the market advertise having a 1,500-watt inverter yet the battery can only do 550 watts continuously as seen here in this review. Others like the Bluetti can do 900 watts output continuously but that is still lower than what it’s inverter is rated to of 1,000w. The point is, the Titan is a class all of its own.

Running the Titan at 3,000 watts for a long time is hard on the battery. Doing it repeatedly will definitely reduce how many lifecycles it has. It is recommended that if you need to repeatedly run over 1,500 watts off the Titan that a second battery be added. This distributes the workload. To ensure the longevity of the Titan battery it should be run less than 1500 watts. But, this doesn’t mean that if you need to run more than 1500w that you can’t. All it means is if you need to run over 1500w every single day that you should have a second battery or more.

This is an awesome feature that people really undervalue in my opinion. The reason is that I’m in control. If I absolutely need to run 3,000w for 40 minutes for some reason then I can. If I do it once or twice it’s not a big deal. Other units on the market though won’t allow me to do it even if it’s just once. For example, if I had a solar generator that the inverter is rated to 1500w but the battery can only do 550w continuously then I have no control. I can run 1500w but only for a few minutes before the safety mode kicks in. So if I only had to do it one time and was not going to do it repeatedly, it doesn’t matter, I don’t have the option to do it. But with the Titan, if I need to run 3,000w for an extended length then I can. Doing that repeatedly is what is not recommended.

If I have the need to repeatedly run 3,000w then I’d need a second battery anyway to last longer than 40 minutes of running the equipment.

All of those plugs previously mentioned are the output plugs. It also has many input plugs such as 2 solar plugs for a total of 2,000 watts in solar power, 1,000 watts each port. Two wall charging plugs for a total of 600 or 1,200 watts per hour charge speed. A car charger plug as well to charge on the go. The car charger plug is an SAE plug that also works as the battery reset plug.

The car charger is rated to 15 amps because the cigarette lighter DC plugs in most modern vehicles are rated to 20 amps. So it’s at 15 amps so it can still charge as fast as possible without pushing the DC cigarette lighter port to the max. Volts x Amps = Watts. So to figure out how much the car charger puts out in watts we take 12v x 15a = 180 watts. That means if the battery were completely dead it’d take about 11 hours to charge. 2,000wh ÷ 180w = 11hrs. That’s on par if not better than other solar generators on the market since the charge speed is limited to 15 amps.

With the battery reset cable, it is very easy to jumpstart the battery in the case that I run the battery all the way down to zero. If the battery hits rock bottom it automatically goes into “safety” mode and stops working. This means it needs to be jumped. The easiest way to jump it is to simply plug in the wall charger and boom, fixed. But if I’m out camping or the grid is down and my battery drains completely I probably don’t have access to a wall outlet. All I have to do is take one of my 100w solar panels, connect it directly to the reset cable, then plug the reset cable into the SAE port for just a few seconds and it’s reset. Now I can start charging with my solar panels once again.

7. Inverter Size

The average size for a portable solar generator on the market is right around 1,500 watts. That doesn’t mean I can actually use 1,500 watts until the battery is drained, but I digress.

In many cases, this has sufficed since not a lot of heavy-duty equipment was being run. Normally just my fridge, freezer, a fan, a light or two and chargers is what is run on my smaller solar generator. But that also meant that heavy-duty equipment couldn’t really be used. The Titan uses a 3,000-watt continuous inverter. This means 3,000 watts of energy can be used non-stop until the battery runs out. It’s technically a 3,200-watt inverter but it’s rated to 3,000 watts so that it is never overworked. Brilliant!

In all the testing that has been done, it has actually been able to handle up to 3,000 watts of continuous use without any problems. It was able to do that nonstop until the battery died about 40 minutes later. It ran a 120v welder and a heat gun without ever slowing down until the battery completely drained.

Even though the continuous wattage is 3,000 the peak wattage is 6,000 watts for 10 seconds! Generally, the peak wattage for an inverter is twice the continuous wattage. This is nice that they kept it at 2x the continuous power output. Surprisingly enough there are other units on the market such as the Renogy Lycan or Humless 1500 that do not have double the peak value.

Not only that the but peak wattage can hold for 10 seconds which is quite long. Sadly many solar generators will only handle 0.1 seconds of peak surge which sometimes is not enough to get large items running.

The Titan uses a Pure Sine Wave Inverter to make sure that anything can be run on it smoothly. Especially in the DIY Solar industry, it seems all too often people use Modified Sine Wave Inverters because they’re cheaper and will run most things. I don’t want to settle and find out something I need to run can’t run on Modified Sine Wave. Pure Sine Wave is the only way to go.

With the Titan, I was able to run my large miter/chop saw which I have not had any other unit use. Meaning if during an emergency I needed to build, repair, cut or whatever with large heavy-duty shop tools, I can do that no problem. Or it also means if I need power out at a job site I can easily run my miter/chop saw, table saw, sanders, air compressor w/nail gun, recharge cordless tool batteries and so on no problem.

Especially with an additional battery and lots of panels I can run all the heavy-duty tools in my shop and build anything I need! Imagine using this at a construction site instead of big heavy diesel or gas generators. Imagine being a contractor and having 2,000 watts of solar panels mounted to the work trailer with the Titan inside. The Titan could have 4 or 5 batteries connected and there would be endless power and never need to run to the gas station. Not to mention no loud generator making noise. Then the music could really be pumped up from the “boom box.”

8. RV Connectivity

There are not many units out on the market that have a 30amp style RV plug. There is one on the Apex generator but it is only rated to 15 amps according to what I’ve been told. The Titan includes a 30amp style RV plug which actually can easily handle 25 amps of power which is enough to run an RV no problem, just like if it were connected at a campsite to the power supply. This is very advantageous to have a fully working 30amp RV plug for those who enjoy RVing, 5th Wheel/Trailer Camping and Vanlife. There’s nothing easier than just connecting the vehicle straight to the RV plug and running the equipment.

Yes, I know people are saying right now “that’s AC power which means there’s a power loss when converted from DC power.” I’m talking about ease of use. Plug it in, and done. With enough panels and even a second battery, inefficiency is taken care of and a moot point.

Some tiny homes, trailers and off grid locations also use a 30amp RV plug to make it easier to connect a generator to it and run everything.

Not everyone is looking for that capability. Some people just need to have the RV plug to run all of their items in their setup.

Because of the large inverter size, battery size and larger fuses the Titan has no problem running the heavier items that smaller units cannot. The Titan can easily run a double Hot Plate, toasters, heat guns and other high wattage items without needing to plug into the larger RV plug and use an adapter to get the higher power needed to run those items.

Some people don’t need an RV plug at all. That’s fine. Having options is one of the many things that makes the Titan such a great unit.

9. Car Charging

It is very common for solar generators to have a car charger option with them. For example, the Kodiak and Apex have car chargers and will charge the Kodiak/Apex in about 5 hours which isn’t bad at all. This means it’s charging at about 15 amps which is pretty high but normal on modern vehicles. Most older vehicles have a 10amp fuse to their cigarette lighter port, others have 15 to 20 amps. We’ll touch more on this in a minute.

Other units such as the Goal Zero 1400 Lithium take 12 hours to charge using the car charger. That means that it is using about 10amps charging speed from the port to charge the Lithium 1400. Again, we’ll touch on this here in a second why this is actually important.

The Titan is able to charge in about 11 hours if charging at 15 amps. This does seem a little longer to charge, and I agree on that. But there is a good reason for it due to what the average car charger port can handle.

Some vehicles have a 20 amp fuse. If you are expecting the Titan to charge in 5 hours then you’re going to be disappointed. The battery is simply much bigger than other units and so it takes longer to charge. If a newer vehicle is charging the Titan then there’s a good chance it will charge in 11 hours from empty. If it’s charging from an older vehicle then you need to make sure that the 12v DC cigarette lighter port is rated to at least 15 amps. If you plug the Titan in and it stops charging from that port then you’ve probably overdrawn the fuse and need to replace it.

One of the cool features of the Titan is that multiple charging ports can be used at the same time. I have never seen this capability on any other unit out there. It has always been that you can only charge from the car, or wall or solar or whatever one at a time. This means on my truck and I could place 3 or 4 panels on my tonneau/bed cover and have them connected to the Titan. Then at the same time have the car charger plugged into as well and charge much faster.

10. Lithium Battery

Lithium has become very common to use nowadays and in my opinion, is definitely the best way to go. There are many Youtube videos and blogs out there that explain how much more cost-efficient lithium-ion is to lead-acid. In many cases, it takes roughly 12 lead-acid batteries to equate to one single lithium-ion battery in terms of power, cycles, and longevity.

A great lithium battery is the Battle Born LiFePo4 battery. Now before you get confused or jump all over me, LiFePo4 is also called “Lithium Iron Phosphate.” Lithium-Ion batteries are also called “Lithium NMC.” The Titan uses Lithium-Ion (Lithium NMC) because it is much lighter weight. A 100ah 12v LiFePo4 Battle Born battery costs just under  $1,000. They are generally found for about $950 online.

12v x 100a = 1,200w. The Battle Born battery has 1,200wh of power in it. The Titan battery has 2,000wh of power in it. If I wanted to add more batteries on my own to the Titan I would likely go with something like the Battle Born because they’re great batteries. But, I would need two Battle Born batteries to get closer to the capacity of just one Titan Expansion battery. I would also need two Battle Born batteries because I would need to link them together to make 24v since the Titan is a 24v system.

Battle Born also has 24v batteries but most people who already have Battle Born batteries have them in 12v. Since the Titan uses a 24v battery I would need two 12v batteries or one 24v battery for external connection. The 24v battery is 50ah which means (24v x 50ah = 1,200wh) it is the same capacity as the 12v battery. Either way, I’d still need two Battle Born 24v batteries to equate to one Titan battery.

This means I would be close to $1,900 to get 2,400wh of capacity, and that’s not factoring in the cost of buying heavy-duty battery cables to connect the batteries together. Plus another heavy-duty cable to connect to the Titan.

I could just save a ton of money, have a lighter battery, not have to connect any heavy-duty battery cables and have the battery stack on top of the other Titan battery. A Titan Expansion Battery is only $1,395. When price comparing, the Titan Expansion Battery is far more affordable and gives me more watt-hours per dollar.

Battle Born (two 12v Batteries) = $1,900 ÷ 2,400wh = $0.79/wh

Titan Expansion Battery (1 Battery) = $1,395 ÷ 2,000wh = $0.70/wh

For the Titan to cost the same as buying two Battle Born batteries (not including additional cabling required) It would have to be priced at $1,595. Because, $1,595 ÷ 2,000wh = $0.79/wh. Even then it’s still worth going with the Expansion battery just for the ease of use.

The Titan is a way better bang for the buck than trying to get a third party battery to connect to the Titan. Now if I already had some Battle Born batteries on hand then I could go through the process of getting the cables and making it work. But with how I am, I think I’d rather have the ease of just one battery that easily stacks.

Plus, each Battle Born battery weighs 31lbs. So two of them means 62lbs of battery. Just one Titan Expansion Battery is about 35lbs, so it’s much lighter. I think I would prefer to sell the Battle Born batteries and get the Titan Expansion Batteries just for the sake of easier usage.

The Titan uses Lithium NMC technology and it uses the highest quality grade. The Goal Zero series of lithium units only have 500 cycles. This is why I love the Titan because it has 2,000 cycles, not just 500. That’s 4x the longevity of the battery.

11. Customer Service & Warranty

This is a big one for me. It blows me away that so many companies want to look big which means you have to push 10 different buttons to get to an operator just to answer a question. This was sadly what I experienced with the Patriot Generator. When I was originally doing a lot of my research I looked at the Patriot Power Generator.

It literally took me days to find a phone number to contact Patriot just to clarify some questions since they had never responded to any of my emails. This is a real deal-breaker for me with companies when they won’t help people out. Patriot is not the only company who I have experienced it with, many companies look small but act big. Funny thing is I get emails from customers of Patriot Solar Generator almost daily because they think I can help them more than Patriot’s own customer service, cause you can’t find it! I help where I can as usual but it’s near impossible to even get a user manual for the Patriot 1500 generator so I can only help so much.

This is one major thing I like about Point Zero Energy. Every single time I have called or emailed I have been answered quickly. I never have to go through a huge menu of where to connect my call to, I get straight to someone who can help.

Because I love the Titan so much and am an advocate for it I also take emails from people whether they’re interested or not. I help people figure out what kit size they need, how much power certain items generally run, what the best solution would be for their situation and tons more. I am ALWAYS happy to help where I can. If I don’t know an answer I will find out and get back. I generally answer same day or rarely longer than 24 hours.

The reason I do this is that I used to be the guy who could not tell you what a watt, volt or amp was. I never knew that Volts x Amps = Watts. I never knew the difference between a Series and Parallel solar panel connection, or even what a Series/Parallel connection was. I understood nothing about solar.

My #1 biggest gripe about the solar industry is that companies use lack of understanding against customers. I hate that. It’s not fair or right to take advantage of people who don’t understand electricity, and almost no one understands it! That’s why I started my whole website and was dedicated to having tried, true and tested complete solar kits that were easy to use and would actually run for long periods of time and charge quickly. Is that so much to ask?

Point Zero Energy

That is why I love Point Zero so much. They are of the same mindset and would rather make an inverter that can do 3,200 watts easily but only rate it to 3,000 watts so it’s impossible for me to burn it out. They take the time to put in a redundant heat sensor in the batteries to guarantee they never get too hot so they last longer. It’s common sense kits sizing and personal help. That’s what I like, and that’s what I try to give too.

Point Zero has been very responsive, but they also include a 2-year warranty on the Titan rather than just a 1 year. Every single other unit I have seen anywhere has included a full 1-year manufacturer warranty. Point Zero took it a step further because they truly believe in their product and doubled the warranty. If anything goes wrong with the unit that is due to manufacturing, they will replace it for free no problem. That speaks tons of confidence in their product to me.

Get Deep Discounted Solar Kits Now


There are dozens of solar generators out there on the market now. Every couple of years a new and improved unit comes out that beats previous technology. Point Zero seems to have taken everything they’ve heard and learned the last few years and applied it to the Titan. I am glad they have listened to others and want to provide the highest quality product available.

Titan 1000 Flex KitThe Titan is my go-to unit now and have been very pleased with its performance, quality and customer service. I think it will be many years until another comes out that can beat what the Titan can do.

I personally use the Titan 1000 Flexx Kit with One Additional Expansion Battery. The Titan 1000 Flexx Kit is the #1 recommended kit for “go-to” size and capability. It’s large enough to run things all day and still charge the battery to full by dinner time.
