It was raining today and I was trying to improve solar charge performance. Read more: http://www.thediyworld.com/blog/?p=1248
I rewired the battery bank and the cables between the solar panels, batteries and the camper load to try and improve overall performance and reduce losses in the wires.
I still have some work to do in order to get the best solar charge performance out of my system, but I am on the way.
