I have a galvanic isolator, and I can see where the output side is connected to a bus that sends green wires to all the A/C outlets.

What I can't see is a connection between this bus and the DC ground. I could have one and it's hidden. But to make sure, is it a simple matter of running a wire from the bus to a good DC ground (ie, the engine in my case)?

My understanding is that this is necessary for safety.

That is correct, per ABYC. To make sure measure for continuity between the DC negative and the AC ground (green wire) bus with a simple multimeter.

A simpler solution for the wiring is a 10 awg green wire between the DC negative bus and the AC ground bus. Best to keep only one ground connection to the engine.

Good point, those two buses are within a foot of each other inside the breaker box!
