So, when parallel wiring batteries it is beneficial to make your load and charging connections at diagonal corners of the battery. I have a friend who will be mounting 4, 12 volt solar panels on a trailer. They will be parallel wired. The panels have J boxes on the back so they will be wired + to + and - to -. Would it make any difference if the + and - home run wires came off the opposite ends of the array, as opposed to both from a single end panel?
