Photovoltaic Modules (PV): convert light energy into DC power, charge the battery through the solar inverter charger, or directly reverse into alternating current to power the load

Power or generator (Utility): Access at the AC input can power the load and charge the battery. If you do not have a power supply or generator, the system can also operate normally, where the load is supplied by batteries and photovoltaic modules

Battery: The role of the battery is to ensure the normal use of electricity for the system load when the solar energy is insufficient and there is no electricity

Household load: Can be accessed to a variety of household and office loads, including refrigerators, lamps, televisions, fans, air conditioning, and other AC loads

Battery Charging Modes:

The solar inverter will have 4 operational charging modes which change the logic as to how and when to charge the battery banks. The solar inverter has four charging modes: PV priority, Utility Priority, Hybrid Charging, and Only Solar Charging.

PV Priority

In PV Priority mode it will make full use of the solar input during the day in order to charge the battery bank. This effectively allows using the unit off-grid during peak utility times in order to cut costs on utility charging. Only when solar fails to start or is interrupted will the unit automatically switch to utility mode for backup.

Utility Priority

In Utility Priority mode, the detected AC input will be a priority for battery charging. If the power becomes unstable or unusable, then it will switch to PV charging.

Hybrid Charging

In Hybrid Charging, PV and Utility will work together to charge the battery bank at the same time. Priority will be given to PV and utilize MPPT charging. Upon PV charging being insufficient, the power supply replenishes with Utility power. This method is the fastest to charge and suitable for unstable areas of the grid, ready to provide an adequate backup power supply.

Only Solar Charging

Only solar charging is the most energy-efficient way to charge your battery bank and does not make use of AC input. The utility will not charge the battery, even if it is available.

Load Output Working Modes

The solar inverter has 3 working modes that dictate how the incoming power is used to power the loads. Users may configure the output source priority to configure load power.

PV Priority

In this mode, only the incoming solar energy and battery power are used to power the loads. This can maximize the use of green energy when selecting PV priority in Battery Charging Mode to achieve overall energy conservation and emission reduction. Upon there being no more usable solar energy or the battery voltage drops to a low voltage setpoint, then the unit will switch to utility power to continue to power up the loads. It is recommended to be in this mode for relatively stable areas.

Utility Priority

Equivalent to a backup UPS for use in unstable areas of the grid, Utility will provide power to the loads as a priority. Solar and battery energy will provide power to the loads only when utility power is not available.

Inverter Mode

The Battery energy will supply power to the loads. The utility provides power to the loads only when battery voltage drops too a low voltage which maximizes the use of DC power.

The instructions are not detailed enough for me to wire this up for use. I asked manufacturer for more detailed manual - with more specific detailed instructions and was pointed at the manual I already have that does not tell me how to install the device. There is NO information in the manual about how to connect a generator. I did not know I would need a generator with an auto-start controller. I need to know how to connect this all in one to my generator that does NOT have an auto start controller - even if I have to do it manually. Also - the manual recommends fuse or circuit breaker outside of box but does not say where or what size or anything. I am off-grid and Need to hook this up. I need proper instructions on
how, step by numbered step. The instructions are not sufficient. It talks about an in-rush current but not how to mitigate or control this risk, for example. There was no explanation for why the internet says a 5000w inverter at 48 volts needs a 4-0 awg cable but this manual says a 2 awg wire is fine. This is deeply disappointing. Why are there no instructions about how to connect a generator. Why is there no information on how to connect the RS-485-2 connector to my battery bms - first of all-my battery does not have a bms - so what do I do.
I am very disappointed that I am simply unable to hook this all-in-one unit up based on the instructions provided. I will have to return it, as the company will not help me I bought it from a re-seller in Canada because I need electricity NOW. I did not know there was a powmr website I could have bought it from if I needed tech support which clearly everybody must given the instructions are useless to anyone who is not an electrician. Surely it would behoove this company to provide exact and explicit numbered instructions including various configurations and recommended types of fuses and where to put them etc... and how to connect generators without autostart controllers and how to connect the system if there is no bms on the battery etc etc etc etc I hate to have to return this but I cant afford to pay someone to hook this up. it would cost just as much as the inverter itself. i am so disappointed.

I put this MrPow 5KW 80A Solar Controller 48V Charger Inverter in my all aluminum enclosed 25' Snowmobile Trailer-to-Tiny Home conversion:

"Six 325w Canadian Solar Panels in series @~258v; Four NPP 200ah deep cycle SLA Batteries @48v in series; 12,000 btu Pioneer Split Air/Heat; Whirlpool 14 cu/ft Refrigerator Freezer; Video editing PCs & laptops TV's; and Misc. appliances."

The MrPow has operated flawlessly for the last month as I finish up the trailer. The split air system, frig, computers, etc. all run on solar during the day with select items running off the battery bank at night. The MrPow has a clearly and well written manual that delineates the units many user-adjustable parameters.

I mounted the MrPow amidship at eye level on the wall. The units cooling fans turn on intermittently mainly at night when operating off the battery bank. Their noise is not excessive. Meanwhile, the MrPow's chassis never runs hot to the touch. The MrPow's operating display is very informative with multiple menu selectable operating parameter sets being displayed. The display is a little small, but it uses intuitive graphical icons and dotted lines to quickly convey the systems operating status at a glance. Personally, I like it very much. There is no phone app, but I find there is something satisfyingly reassuring about physically assessing the systems status in-person on a regular basis. Hey, it's never more than 10 feet away.

I really like the 80 amp MrPow all in one system. I find it much preferrable to a system of multiple individual components and their incumbent rats nests of wiring. The MrPow succeeds at integrating all the system components into one unit that just plain works well. The 5KW pure sine wave inverter is sensitive-electronics safe. Finally, with this setup I didn't even need a soft start device to run my 12,000 btu split-air ac/heat pump system. Less is more.

"I am updating this review today since the customer service support from SpringMirror was kind enough to send me an updated manual. Since they have new feature of Boost Charging and floating charging since it was not included from the previous manual.
The new manual also explain the 3 different kind of lithium Iron batteries and the have nice feature on their paramaeters of the software to set your lithium battery. Also since I am very interested on their Wifi Plug07
system to communicate wireless to the Solar controller system they will send me the unit as soon it will be available in their store for free. I thank them for their generous gesture very good customer service to deal with.
Updated it 5 STAR!

I am only giving this a 2 star due to a few things that I am not very happy! First there is no communication software no cable and Cd software! Second the support they reply very slowly! No wifi or bluetooth option for communication. Manual are very poorly wriitten the Boost charging very hard to understand how it works with a timer of 900 minutes. Also the lithium choices for LF4/LF5/LF6 no explaination what is the difference. I think the brand of this product is POWMR but hard to ask support I emailed them no reply. I will not recommend this product unless they communicate and help me with my issue I am thinking of returning this product."

"For the price- it works better than expected. Sure it can be a little loud when then fans kick on and yes the idle draw is fairly high, but if you have a 100ah battery and you are drawing 1ah, it's 100 hours before your battery dies completely. But it works as it should and the MPPT controller is super efficient.

In the end, I am completely happy with this device."
