Hi Carter,
I think that it's no different than your boat on ICE, the only change is that all the electrical aspects of your drive should be a single isolated system.
I would consider your solar array as part of the drive, as long as you've got the controlled output going directly to your traction batteries.
Do what was already done with your house DC and AC systems. I believe that only electrical connection between the drive system and the rest of the boat would be an isolated DC-DC converter. Everything else should be seperated.
Fair winds,
Eric

Not to mention the 5 kW solar canopy which I have gone to great effort to keep isolated from the boat.
