Works as it should and the seller helped me answer a question promptly.

Easy install, works like it should. value priced all in one unit!

uper easy install .. 8 wires to connect. good english manual.. keep it handy as the menus are all numbers instead of complete words like my $10,000 system... only need to set a few parameters once, even if all power is disconnected.
built in transfer switch is fast. no flicker on mains to battery transfer. use solar or not! nice UPS, lithium profile good on my 48 volt pack from batteryhookup.com. nice low amp draw with the higher battery voltage, built in MPPT control works. good looking circuit boards... try to find a USA seller with one in stock. got mine in 4 days, added a couple shut offs and breakers to critical loads sub panel . runs microwave, fridge, wall heater , more? at the same time, 2 variable fans not too loud in garage, china made. .


Easy install, great value

This thing and a few 200w solar panels and I have an all electric RV. This little unit greatly simplifies the installation process by incorporating the controller and inverter into one unit. I used a 48v Li-PO4 battery with 24v panels. Just hook your panels in series, not exceeding the open circuit voltage max of the controller. I have 2 series in parallel. This produces 130v, enough to start charging before sunrise.

Unit works great but only Wi-Fi issue

It’s an awesome unit it works great tied to a grid once battery runs lower than I set it will kick in from utility power. Only thing that bothers me is Wi-Fi dongle doesn’t work the seller promised to send a replacement dongle but it never arrived


This thing replaces the need for multiple components in a solar system. It has both the solar charge controller for just about any type battery you own plus a 3500 watt pure sine wave inverter contained inside. And what makes it so valuable is that it can be connected to house current or generator to produce battery back up and battery charge when solar is down. So it can make sure your batteries are always topped up for emergencies. An equivalent set up would include many components you'd have to mount in a system to perform the same function as this device. It's possible to connect up the entire system in a few hours without racking your brain.
And the unit features preset parameters for each type battery including several different types of lithium battery types. It monitors, charges and controls the system to give optimal and safe operation. It can also be fine-tuned if you need to deviate from the default settings in each category. So programming this is a snap. No need for a separate a-c to dc converter to use the generator of even house current to back up the solar panels. And it's ability to customize the settings so you can make it solar, a-c or combination of the 2 preferred gives your system a great deal of reliability.
