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.

Renogy Lycan Review

Searching for the best fuelless solar powered generators on the market can be a pretty daunting task, especially if you are new to researching generators. There are a surprising amount of options on the market and it can be very difficult to compare and contrast them. No two generators are exactly alike and they actually have very many differences to them, which makes figuring out the best generator for the price very difficult. I have put together a comparison chart that explains the pros and cons of several fuelless generators on the market currently, and that can be a great jumping off point for you.

If you are looking into the Renogy Lycan generator in particular, read on to get some more information.

Lithium Ion Battery

One of the great benefits to the Renogy Lycan generators is that it has a lithium ion battery as opposed to a lead ion battery. This can impact a few different things, one of them being the weight of the entire unit. As batteries go, lead is one of the heavier ones, so if you’re looking to have a fuelless generator in your home or on the road with you, and you want it to be easily transportable, you should immediately strike the lead battery generators from your list.

For example, the Nature Power 1800 generator with a smaller capacity battery than the Renogy Lycan at 960 watts (versus the Renogy Lycan at 1000 watts) has a weight of over 20 pounds heavier, using a lead acid battery. The Goal Zero Yeti 1250 generator that also uses a lead battery, exceeds the Renogy Lycan at 103 pounds. So as far as weight is concerned, the Renogy Lycan is a far better choice because it has a lithium battery, which is lighter weight. However, there are still some other generators with lithium batteries that are even lighter than that that you can view on the shop page.

Another benefit of the lithium ion battery is that, according to some, lead acid batteries may be something of the past. Yes, they have been reliable for two centuries, but lithium ion is beating them at their game. Lithium ion batteries are more resilient to extreme temperatures and they recharge in less than half the time it takes for a lead acid battery to do the same.

Lithium batteries also take little to no maintenance to ensure they run smoothly, while lead does require some care. If you are planning to live off grid or even just vacation of grid, having a battery that doesn’t need to be maintained over time is a very important feature. Though lithium batteries may be more expensive upfront, they are the more frugal choice in the long run because their lifecycle costs are among the cheapest options out there. You can plainly see that lithium is the best longterm choice, when you compare the Renogy Lycan’s lifecycles at 2000 versus the lead acid battery generators Nature Power 1800 and Goal Zero Yeti 1250 at 500 lifetime cycles each. Lithium ion batteries are just more efficient, lightweight, and longer lasting, which are all important aspects if you are trying to be self-reliant. The Renogy Lycan generator is just one of many different kinds of lithium ion battery run generators on the market right now.

Battery Capacity

The Renogy Lycan has a battery capacity of 1000 watts, which makes it competitive with some of the most efficient and best reviewed solar powered generators on the market. When you are looking at battery capacity, more is usually better. It is difficult to know exactly how much wattage you use in a given day if you don’t actively track it. So when you are in the market for a generator, you may want to take some steps to find out exactly how much you use. You can do this by getting your monthly utility bill and dividing it by 30. Of course, keep in mind that you don’t have to have under 1000 watts to make the Renogy Lycan useful, especially in emergencies, because you can recharge your battery at any point during the day. If you find that 1000 watts seems a bit low for what your needs are, there are other options available.



One of the few areas where the Renogy Lycan doesn’t quite shine is with the inverter. The inverter controls how much wattage the generator can expend at any one given time. So the continuous inverter rate for the Renogy Lycan is 600 watts, but it’s peak is 1200 watts. It is pretty standard that the peak would be double the output of what the inverter can handle continuously. When you compare these rates to those of similar fuelless solar powered generators on the market, you will find that it is a pretty low wattage. For example, the Kodiak can continuously run 1500 watts through the inverter with a peak of 3000 watts. This is more than double the capacity of the inverter for the Renogy Lycan. Of course, it all depends on what your needs may be for a power outage or for daily use, but there are other options with a higher inverter capacity on the shop page.


Another important feature for any solar generator that you want to use in case of emergency is how many outlets they have and what kind. The biggest thing you will be looking for in an emergency power outage is convenience. If you have a generatorthat you only have for a backup and you find that it has a limited amount of outlets, you might not be in a position to run to the store and grab extension cords etc. during an emergency.

The Renogy Lycan is about average to good when it comes to the amount of outlets it has in comparison to other similar generators. It has three standard 110v, one 12v car outlet, and four USB ports. This could very well be exactly what you need. Only a couple other generators have more outlets available than these that you can see on the shop page.

One outlet that the Renogy doesn’t have, that would be helpful is an RV outlet. If you go vacationing or plan to use your RV as an evacuation vehicle in case of an emergency, you definitely will want to invest in a solar powered generator that has this outlet. RV batteries aren’t typically meant to run continuously to heat the vehicle if you are out in the winter, and a backup generator can take a lot of the workload off of that in case you have nowhere to hook up.


Having a backup generator in case of emergency is great, but it’s important that you are prepared for every situation, and sometimes the generator’s battery won’t be enough. Some solar powered generators on the market aren’t expandable, meaning that you can’t have another backup source of power in case you need more energy than you can get from your generator’s battery and you are unable to recharge through your solar panels. In an emergency, you might be on the go and not able to set up your solar panels or you could be working in non peak solar hours. Anything could happen and it’s smart to be prepared for any situation.

The Renogy Lycan can be expanded in to one identical Lycan battery. So you can expand, but your options for expansion are limited to just one. Most of the generators on the market are similar to this set up or aren’t expandable at all, so this is pretty average. The Kodiak is one exception where you can expand it infinitely with 12v batteries. So the Renogy Lycan is up to par with most generators, but if you are looking for some extra battery capacity, there is one other option out there.

EMP Proof

As before mentioned, if you are interested in solar generators as a form of energy in case of emergency, it is important to be as prepared as possible for emergency situations. One of these situations is an Electromagnetic pulse attack (EMP). These attacks are something that could be common in our near future as technology improves and expands throughout the world. One of these large scale attacks could wipe out the power to an entire country, but there is a way to protect your electronics from this. The Faraday Tech Protect bags have been tested time and time again against these simulated attacks and stood up against them. They come in many sizes and you can store a lot of equipment in there along with your generators. Anything with a microchip should be protected.

Obviously, these bags are more costly the larger they are, and one disadvantage of the Renogy Lycan is that it fits into the largest bag on the market. There are a few other generators that are much smaller and will fit into smaller bags that you can find on the shop page.

The absolute best solar generator we have found to date is the Titan. It far exceeds all expectations and is much more powerful than the Renogy Lycan. You can find more information on it here.
