Rick:
If I had to guess I’d say you have a PV wiring fault. The PV positive may be shorted to ground. This would make the inverter chassis negative in relation to ground. The logic I use is to ask what is the likely source of DC at 195 volts? It is most likely the PV circuits, wouldn’t you say? If the DC Fault is not eternal then it must be internal to the inverter. This could be a dangerous situation. I would proceed with caution. Try completely isolating the PV from the inverter as a start. Good luck.

We have a customer whose 12kW is measuring -195VDC to ground from L1 and L2 with the Gen breaker open. L1 to L2 = 0V. I know the Gen input can be configured as an output, but reading a high DC voltage to ground is concerning. The generator has never been run. System is operating normally. Anyone have a Sol-Ark accessible that could verify what they’re reading? Thanks in advance.
