"Do what you can with what you've got wherever you are."-- Theodore Roosevelt
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?
