"Be prepared"-- Boy Scout Motto
your charge controller has 48v PV inputthats only one panel you have to come off the roof at 37v and 70 amps 70 amps requires massive wiring picking a controller with a higher input might be betterif you can double the voltage, you would cut the amps and cut the wire size needed https://www.windynation.com/jzv/inf/choosing-right-wire-size
Thanks RWS! If I’m running each string to a combiner box with breakers I can forego the fuses correct?
