What Solar Controller would you recommend for 4 of these panels on top of my RV?
I am mounting 4 of these Sunpower 435 watt panels on my RV roof.
48 Volt Lithium Battery Bank
1) What controller would you use for my 48 volt battery bank and these type panels.
2) Wire in Series / Par.
1 of 4
2 of 2
3) In addition I am wiring 2 additional of these panels - mounted on the side of my RV that will be able to tilt up like a small awning over a window, but these 2 panels will be on a smaller separate controller.
