Helga’s Solar Install – Part2

Part two of the solar install will deal with the cabling and connections.

Cables on the roof were secured with Eternabond roofing tape to keep them in place, I see so many installs with cable fasteners screwed into the roof, which doesn’t make much sense to me, why put more holes in the roof than you need to.

Inside the RV I mounted the MPPT controller in the pantry cabinet that is directly over the factory converter, wires were fed down to factory battery connections at converter.  I chose a MPPT controller because I went with a slightly smaller panel than I originally planned on (wanted flexible and I got a deal on this one) and I wanted to squeeze every last bit from it that I could, MPPT controllers can be up to 20% more efficient than PWM controllers, which means I get as much charge as possible from my 85w panel.
