Epever 3210an with MT50
Dr. Prepare 12v 100AH battery
4x100w solar input. No grid
When I hit peak sun the voltage will spike to 17v. Obviously this throws a code and stops, but then restarts after the volage settles. I've been lucky enough to catch it every time and shut down the PV. Previously this was hooked to a flooded battery and worked perfectly, then an EG4 that would never charge past 13.3v. We determined it was a BMS issue and I moved to the smaller Dr. Prepare battery. When I hook up an old PWM it maintains voltage correctly. Although I'm not sure if its the EPever's fault or the BMS.
I've tried setting up parameter's via a laptop and using settings that worked previously for other users with this issue. However the CC doesn't seem to listen to the settings. Bad CC or bad BMS? Hopefully it hasn't done any damage.
