| Any decent meter will have a high input impedance on the Volts setting otherwise it would provide an inaccurate reading.
Our customer, who first reported this, is an engineer with a well-known charge controller/inverter company. He used a cheap meter whereas I used a Fluke 87-5. Both had the same readings.

My first thought is what meter are you using? Some meter will have high input impedance and give false value Back on the Sol-Ark topic again. 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?
