Have seen some references to this issue on the forums.
Today I noticed that my lithium 12v WEIZE brand batteries in series were sitting at 27 volt float. This seems to be normal. Although, the scc was reading no charging from my panels. This is off the grid no external power.
I turned on my inverter that has a small load connected. Immediately the panels started providing current to charge the batteries again.
This began a cycle of voltage spikes read from the scc from the batteries. Voltage would spike. Inverter would shut off. Voltage would immediately drop and inverter would turn back on.
I turned inverter off. Came back after 30 mins. SCC was reading fine and then voltage would go up to about 28.2 and then overcharge discharge. Current was not flowing from my panels into the batteries.
I turned on the inverter and plugged more load into it to suck the batteries down just in case. The inverter to battery voltage rise loop did not happen again. Everything seems to be normal now. Battery voltage has dropped to 26.5 feeding fridges and computers etc.
I am guessing none of these warnings had to do with the actual battery BMS. Is this correct? Does anyone have any idea where to start with this issue? Should I take the batteries out and make sure they are near equally charged?
Any help is appreciated.
