Hello I am sorry in advanced if this is a noob question or problem.
I have a Big Battery brand Wolf 24v LiFePO4 that use A123 cells in 8S6P that claims to have a low voltage disconnect of 20v, however I let it run down to just under 22v according to the built in voltage reader and I assume the BMS disconnected as I can't get it to turn back on. When I test the terminals it reads 1.9v. I have an MPP Solar 24v AiO inverter LV2424 model but now won't turn on or charge the battery even when full solar power is available or when I try to hook it up to utility.
The MPP Solar manual says that it can't charge up batteries with extremely low voltage <1.4v, even though the terminals read at 1.9 I would assume it should be able to charge but without even being able to turn the battery back on I'm not sure what to do. My only other thought is that I need to get an AC charger for 24v batteries but would like to avoid purchasing any additional tools unless absolutely necessary.
