LiTime 3500W Pure Sine Wave Solar Inverter Charger, 48V DC to 120V AC All-in-One Solar Inverter, Built in 80A MPPT Charge Controller, for 48V Lead Acid/LiFePO4 Battery, Home Energy Storage, Off-Grid

This is my 2nd all in one inverter, the first was a 24V 3000 watt Eco Worthy that I'd been running for a couple of years now. I wanted the extra capacity of the 48v system plus the additional inverter output. It was easy to install and has been running great for the last 30 days. Unfortunately, in the Pacific Northwest, we have not gotten much solar in December, so have not been able to fully test the system. I am running LiTime 12V batteries and so far, no complaints

Got it working with Eco-Worthy batteries. We choose LiTime charger/inverter mainly due to its larger size to output rating ratio. Bigger charger/inverter indicates product is properly designed for US market with 120v AC, which needs bigger wires, larger heat sinks, and more space for ventilation. Issues: 1) we can't get BMS communication working with Eco-Worthy battery. 2) There is no wifi/Bluetooth support. 3) PV high voltage is relatively low at 145v.

I bought this for setting up a solar install on my little 26' Class A RV. This unit can handle a max of about 150v solar power but starts much lower. This means that I can string 3 or 4 of my 25v solar panels in series and the built-in MPPT solar converter will deal with it. Most of these all-in-one systems are 125v MINIMUM which is not ideal for a small RV install. This unit works with my 48v (actually 52.5v) 100 amp server rack batteries, taking power from them as well as charging them from solar or AC input. And finally, it provides 3500 watt AC out which matches my small (ish) RV, which has a 3500 watt system internally. Everything I need specifically for my RV.

Easy installation, instructions could be better. Working very well.

It arrived without the user manual. The battery icon also constantly shows that it's charging, even when it's not connected to the grid—just the inverter and the battery itself. It shows that it's charging when it isn't. Is this normal?

Quiescent (vampire draw) is too high. Draws 50W when doing nothing. So you'll need to produce 1.2kWh each day just to do nothing. Not good for a van build or other small environment. You can turn on eco mode, which reduces this to 30W, but my air conditioner won't start in this mode, so I can't use it. There's also no way to just turn off the inverter function, while leaving the solar charging running. So instead, I use a dedicated charge controller to charge the battery, and fully turn off the LiTime. I use the LiTime for running larger A/C loads and for charging the batteries from A/C.

I purchased this unit to build a battery backed up power source for a remote radio site. It is pretty straight forward to install and program and you can find a few YouTube videos to help also. So far it is working well for my needs. I wish that it had included the cloud based wifi monitoring module that a few other brands of these units include, I thought that it did and was a bit disappointed that it didn't.

i mislaid my operating manual/instructions and it isn’t available anywhere on the web as a download, as far as i can tell. to frank; the other reviewer who is using it with eco-worthy batteries: the eco-worthy battery manual says you can’t use a straight-through cable for the rs485 inverter connection, you have to swap some of the pins. i haven’t tried this yet but will test tomorrow. a normal straight through ethernet cable won’t work for the bms to the inverter.
