Nearly no one has heard about the Hysolis MPS3K solar generator that has been on the market for quite a while. And even more, hardly anyone has had a solid review on the MPS3K. It is a direct competitor to what has been considered the reigning champion, the Titan. The other main competitors are the Bluetti AC300 and the EcoFlow Delta Pro solar generators.
How does the MPS3K compare to these other strong solar power stations? Does the Hysolis MPS3K have enough power and expandability to be able to run all essential equipment during a blackout or emergency? It definitely looks like it can, but let’s find out for sure.
It should be said upfront that this is definitely a very good unit and is extremely powerful. In many cases much more powerful than other solar generators. But that comes at a cost, and not a financial cost. It comes at a cost of convenience. Not only is it a heavy unit, but it is less user-friendly than other solar generators. For some people that is a good thing because they don’t like the bells and whistles of Wi-Fi, Bluetooth, wireless apps, and firmware updates.
So how does it compare directly to the other units on the market? It’s definitely top of the list. The MPS3K is up there with the Titan, Delta Pro, and AC300. Here is how they stack up against each other:
Inverter: MPS3K 3,000w | Titan 3,000w | Delta Pro 3,600w | AC300 3,000w
Base Battery Capacity: MPS3K 4,500wh | Titan 2,000wh | Delta Pro 3,600wh | AC300 3,072wh
Max Battery Expansion Capacity: MPS3K 27,000wh | Titan 270,000wh | Delta Pro 10,800wh | AC300 12,288wh
Base Solar Input: MPS3K 1,500w | Titan 2,000w | Delta Pro 1,600w | AC300 2,400w
Expanded Max Solar Input: MPS3K 3,900w | Titan 2,000w | Delta Pro 1,600w | AC300 3,000w
Customer Service: MPS3K, Very Good | Titan, Good | Delta Pro, Good | AC300, Very Poor
Base Price (Varies): MPS3K $3,595 | Titan $3,395 | Delta Pro $3,599 | AC300 $3,699
Price Per Unit Wattage: MPS3K $0.97 | Titan $1.51 | Delta Pro $1.42 | AC300 $1.84
The price of the MPS3K alone is amazing since you get nearly all the same main benefits of the other solar generators, but the MPS3K is below one dollar for the price per unit wattage. The price per unit wattage is a combination of comparing the inverter, battery, and solar input. Too often units are only measured against the battery, but that’s only one key feature of a solar generator which is why I compare them against those three features. For the features you get, it’s literally twice as good as the AC300.
In terms of how it compares to all of these other Heavycap units, it’s pretty much a winner in nearly every way. The 3,000w inverter is plenty strong. It doesn’t have the best maximum battery expandability but it’s extremely rare anyone ever has more than 10,000wh of battery. And it is unparalleled in solar input when expanded with extra batteries. And for that price, it’s basically unbeatable.
The Hysolis MPS3K has a powerful 3,000 pure sine wave inverter. It has been found by nearly all solar generator users that 3,000 watts of output power is plenty for most people’s needs. It will only do 120v power, it cannot connect to another MPS3K in order to make 240v power. That will be a feature of the Hysolis Apollo which will be the big brother to the MPS3K.
3,000w of output capacity is plenty to run fridges, freezers, portable/window A/C units, lights, fans, microwaves, toasters, coffee makers, TV, Wi-Fi, and much more. It has the same size inverter as the Titan solar generator which has proven to be a very powerful solar generator for years. The Bluetti AC300 also has the same inverter capacity. The only solar generator of the same class that has a larger inverter is the EcoFlow Delta Pro with an inverter output capacity of 3,600w. In my many years of using solar generators, 3,000w has always been enough for everything I need it to do, so it’s not a problem that it’s not the largest inverter in the industry for Heavycap power stations.
It can surge up to 6,000w for those large inductive loads that are often found with heavy-duty power tools such as chop saws, air compressors, and electric drills.
The Hysolis MPS3K has four 120v (Nema 5-15R) house-style outlets. It also has one RV plug (TT-30R) that is rated to output up to 25a continuously. It includes a 12v DC cigarette lighter plug as well as multiple USB charging ports.
The Hysolis MPS3K uses an extremely large battery pack made out of Lithium NMC batteries. It has a total internal battery capacity of 4,500wh which is the largest of any solar generator’s internal battery capacity currently on the market. Because it has a 4,500wh battery and the inverter is 3,000w it is literally impossible to drain this battery faster than a .67 C rate.
A .67 C rate means that even if the max output was being used on the Hysolis MPS3K it wouldn’t hurt the battery. It means the battery can never be drained really hard which greatly increases the life cycles to help it last longer. It easily has 2,000 life cycles even though it’s a Lithium NMC battery.
Typically, Lithium NMC batteries do not have great life cycles and that is one of their biggest drawbacks. But they are much lighter than LiFePo4 batteries which makes them more portable. LiFePo4 batteries are heavier than Lithium NMC but have many more life cycles. Since the MPS3Ks battery is so large, it can easily handle many years of non-stop use and not degrade as fast.
It is a 44v system which is basically the same as a 48v battery system which is considered to be the most efficient way to use batteries when converting to AC 120v power. It’s much easier to convert 44v power to 120v power than 12v power to 120v power. Most batteries on the market are made in 12v which means it takes a lot thicker cabling and much more work for the inverter to get 120v. Having a higher battery voltage means you have a higher inverter efficiency which leads to getting more power out of the battery than a lower voltage battery.
But that’s not even the best part! The MPS3K can easily add five more batteries of 4,500wh each. That means it can easily get up to 27,000wh of total battery capacity! That’s massive! In my experience, that is easily enough power to run emergency essential items such as a fridge, freezer, lights, fans, and other appliances/devices for 4+ days even without any solar panels connected.
To add the extra Hysolis MPS3K expansion batteries is as simple as making sure the batteries are within 3v of each other, turning off the breaker for the batteries, connecting the new batteries, connecting the communication wire, changing the connection toggles on each unit (as shown in the user manual), hold the reset buttons on each unit and then turn on the breakers. And just like that it’s easy to go from 4,500wh to 9,000wh or up to 27,000wh depending on how many batteries are added.
To put that into perspective, having 27,000wh of total battery capacity is nearly the same as having 13 additional Titan expansion batteries attached to a Titan ($18,135 in batteries). The Delta Pro can only expand up to 10,800wh of battery capacity ($5,398 in batteries) at its maximum for a single Delta Pro unit. Not even the Bluetti AC300 can expand as high as the Hysolis MPS3K. The AC300 can expand up to 12,288wh of maxed-out battery capacity ($6,297 in batteries) for a single AC300 unit. The MPS3K maxes out at 27,000wh whereas the Titan can expand to as many batteries as are needed. But from my experience, it is rare for most people to go above 10,000wh.
A Hysolis MPS3K expansion battery is only $2,860 per battery. For a total of $14,300 for five extra batteries, the system will have more storage capacity than any other competitor. This is incredible, less cost per watt-hour, and more capacity, that’s a true win/win.
But it still gets better. The Hysolis MPS3k reviews as one of the very top-recommended units for 120v power because of how fast it can recharge from solar and wall charging. The standard wall charging speed is 1,000w which is quite fast. The only unit that has a faster wall charger is the Delta Pro at a max of 1,800w. All of the other solar generators have slow-wall chargers.
The big benefit to having a really fast wall charger is being able to fully recharge the system quickly off of a gas generator. I personally use a propane/gasoline generator as a backup to my solar generators. In the event of really bad weather or other issues where I cannot get a good charge from solar panels, I can recharge the system in under 5 hours from 0% to 100% using the wall charger. And because the battery is 4,500wh it won’t charge it too fast which would reduce the life cycle.
When it comes to solar charging it has an impressive 1,500w solar input through an MPPT charge controller. The charge parameter is 60-150v and 30a. Very similar to the Titan’s solar input of 35-145v and 30a. That means it’s extremely easy to over-panel the Hysolis MPS3K solar generator. It’s easy to connect as much as 2,000w or more in solar panels to the unit so that it is making full power earlier in the morning and later into the afternoon. That is the power over-paneling, it increases the number of solar peak hours in a day to more than 5 hours. This makes it much easier to get a full charge even when weather conditions are not very good.
But wait, there is more! Not only does the MPS3K have a 1,500w MPPT charge controller which is great on its own. But it’s possible to add up to 2,400w of solar panels to each expansion battery! This is unheard of at this level. The Bluetti AC300 batteries are able to add 200w of solar to each battery, but that doesn’t even come close to the 2,400w that can go into the MPS3K Expansion batteries.
That means that with one expansion battery the MPS3K can have a total of 3,900w going into it from solar. You can only add one additional MPPT charge controller because when you add multiple batteries you use those ports to expand. So once more batteries are added there’s only one extra port for another charge controller. The only requirement is to get the Hysolis MPPT charge controller for each battery. The Titan has had the largest solar input of any system for many years at 2,000w of solar input. That has now been very excessively beaten with the MPS3K’s capability to add more solar to each battery.
The Hysolis MPS3K has a great solar input on its own, not to mention adding more power to each expansion battery is incredible.
It also does have the ability to charge from a 12v DC outlet such as a cigarette lighter port but since those can only put out up to 120w maximum it is unlikely that anyone would want to recharge their MPS3K using a 12v DC outlet.
The Hysolis MPS3K inverter is plenty strong for everything it needs to do. The battery capacity is good on its own, but then still has the ability to add quite a bit of battery capacity. The solar input is incredible. 1,500w of solar input is plenty for this system cause then it can be charged in just 3 hours but adding even more solar with the extra batteries is a massive advantage that no other system on the market has.
The setup and user experience are definitely the hardest parts of the MPS3K. It looks very basic, doesn’t have a ton of info to give out, and putting it together with extra batteries takes a close look at the user manual. When it’s been done once it all makes sense. But doing it the first time to set it up takes a little patience for sure.
It’s also very heavy, at 121lbs, this is a tough one to move around with just one person. It is 100% recommended to get the moving cart option with this unit because it will make life much easier to move it around.
The Hysolis MPS3K beats all of the other Heavycap-sized solar generators in most ways. It has a very strong inverter, massive battery expandability, a massive solar input capability, and an amazing price.
I don’t know that at this time it can be beaten. For so long the Titan was the king, is that still the case? It’s debatable, but pretty much yes it beats it! The MPS3K absolutely gives it a serious run for the money.
What I know for sure is that should be taken very seriously when looking at backup power. And before a blackout, hurricane, flood, fire, or any other major issue arises, you want this unit in the garage ready to go for all of your backup power needs. I would not wait until it’s too late to get this because we never know what the supply chain issues will bring next.
