Hi All!
During the bitter cold last week, our Mr Cool DC inverter universal 4/5 ton heat pump was running through the night. In the morning, wife noticed house temperature was decreasing but air handler was running. I discovered condenser/ compressor CB had tripped. I reset the 50 amp breaker and then a loud pop was heard 20 seconds later. I reset the breaker again and got the unit to spin the fans but shutdown after 1 minute. My circuit board was fried and ordered a new one. In addition, my house shows other unbalanced issues in the GFCI circuitry when the battery voltage gets low or when system enters bypass mode. I am running six (6) EG4 6500EX in split phase with 10 LifePower4 batteries. NG bond only in AC input panel, all internal inverter NGB circuitry is default configuration.

Any thoughts on what might be causing this?
Thanks in advance!
