I don't quite understand the solar array wiring. There is an extra set of "lines" there, I think. Are you planning two sets of panels in series and then those two sets in series?
I bet you have some design considerations to explain the 'extra' shore/generator input for the A/C unit. This is often accomplished thru a single shore power plug but I bet you know that.
The solar panels will be two pairs of panels in series and then in parallel. I think you are referring to the green wires on the solar panels? Those are grounds. I'm not sure if they are necessary but I'm just following instruction manuals from the panels. I'm not sure where the ground from the 80 amp breaker would go?
My thoughts for the independent input for the rooftop air conditioner: I will run a 20 amp male end off of the roof top unit. I will then have two separate 20 amp female plugs (one from the inverter/panel and one that runs to it's own 20 amp male end).
I want to be able to put the rooftop a/c independent of the inverter if needed really. The rooftop pulls 1725 watts and my inverter is only 3000 watts. I will have a mini-split a/c the is run only from the inverter.
A couple reasons:
1) If it's super hot out, I don't know if I can run the rooftop, mini-split, and everything else at the same time. I don't think I can. But I should be able to run the mini-split from the solar and the rooftop from the generator if needed.
2) I can plug the rooftop itself into shorepower if available and run the rest from solar or plug it into the other shore power outlet
