With my solar
install I am going to use MC-4 cables
and will likely buy an extension set to get from the panels
to the controller. Im concerned about voltage drop. All the MC-4 cable extensions I have been looking at seem to be 12 gauge wire. I will have (4) 100 watt panels
. (2) on each side of the boat. The run from the strbd side panels to the controller im estimating at 18', one way so 36' round trip. Im thinking I would be better off with 10 or even 8 gauge wire? So should I just use the MC-4 cables
to get me through the deck
and then step up the wire to 8 gauge or are there heavier gauge MC-4 cables available? The run on the port side to the controller should not be more than 10' round trip so I guess 12 gauge would be fine there?
