Sun Power

Well, I'm about to take the plunge and order a 540 Watt Solar Kit.

The question I have is how to route the power down to the battery box. I'd like to keep the hull penetrations down to a minimum. I'm thinking of using a conduit and clamps.

Any suggestions?

I ran my eight panels' two 4AWG downfeed positive cables through the insides of a hollow roof rib on the passenger side, and the two negative cables are in a driver side rib. They penetrate through the roof skin under the two combiner boxes that are weatherproof Bell 5348 aluminum junction boxes bolted to the roof rib and well sealed, and these boxes sit under my roof walkway that keeps almost all rain off them anyway. I had to drill 1" holes through the longitudinal box-sections above the windows so that I could access the ends of the roof ribs from underneath, but then it was easy to use 1" ID plastic tube as a flexible conduit for the cables running down to and through the floor to the breakers and charge controllers in a luggage bay underneath. I have blocked off two windows on each side, and the cables' conduits run between the new outer skins and the inner wall panels, then through the side walls under the windows. Doing it this way was a lot of work, but the cables are completely protected from weather or damage and they are also completely hidden from sight, yet if I had to replace them they could be easily fished all the way through from the roof combiner boxes down to the luggage bay.

I ran down through the roof. Not the best idea, but silicone is awesome. Inside the bus i ran conduit down both sides. With boxes and banana clip set ups. A battery bank separate from the bus power, but can be charged by a 360 amp alternator. Under the right conditions. So much left to learn

I used two of THESE. Sturdy, clean, and no leaks.

If memory serves me, to accommodate that kit, you are going to want to use a #6 wire from your junction box down to your charge controller.
