Perhaps someone can help me with this solar hook-up question.
I have 4 six volt batteries hooked-up as in the diagram below for 12 volt power to the house. I want to hook up a solar
panel(s) to keep the batteries charged during coach storage. I want a simple system basically -panel(s)-regulator-batteries. My question is where do I hook up my solar
panel(s) ( -) (+) wires to the batteries to get balanced charging to all 4 batteries. Thanks Allen
