My SG48100m battery is stuck in UVP mode. It's been cold here for the last several days so I had the battery and inverter powered down. SOC was ~50% when I shut it all off. Its well above freezing today and when I turned the system back on the inverter gave me an error 71(battery not allowed to discharge). I checked the battery and it seems to be stuck in UVP mode and wont allow charging or discharging. Voltage is 49.7v though so it shouldn't be in UVP mode as far as I can tell. I tried resetting the battery but it's still in UVP mode. Anyone seen this before?
