I'm fitting out a sailboat as a liveaboard. This will include as much solar as I can fit.
I'm trying to design the solar wiring harness. And I want wiring I won't have to redo from scratch every time I make a change. I don't expect that my first arrangement of solar panels will be my last, or that the set of MPPT controllers I buy when I start will be all I ever buy.
So what I'm thinking for wiring is to position solar cable entry gland housings at various points on the boat:
Then to run cable from there to a centrol location, where I'll have disconnect switch on every cable, the other end of which will run to the various MPPTs.
I'm also considering some sort of patch panel so I can choose which solar panels to to which MPPT controller.
There will be at least three MPPTs, because I have three separate banks - 2 ea. 48V systems for propulsion, one for each of the electric motors, and 1 ea. 12V system for house loads.
There will be six or eight sets of solar cables running into this. At least three MPPTs possibly powered from it.
Anyone have ideas about available hardware that would make this work?
