Need more than this, we have amperage, we need distance, temp, # of wires per conduit, also at 480 you may want to verify cold temp for over the top voltage @ VOC, any RSD device(s) being used? Help to have total module count, as an example use a combiner to make 4 strings, 2 of equal voltage per input. For battery backup or off grid, Solark is the easiest you will get.
