so here is the calculator for 2S2P: suggested 150|35 by calculatorIf you plug the numbers into Victron's MPPT calculator you will see that the SCC could generate up to 37A output with those panels.
According to Victron's MPPT calculator, if you go 2S2P with those panels you will want the 150/35. If you go 1S4P you will want the 100/50. The 100/30 would work at 4P but you would be giving up some amps so going with the 100/50 lets you take full advantage of the amps it can generate with the panels. And it gives you room to upgrade to 5P if you wanted.
Between the SCC and the battery you have 20 feet of wire round trip. If you use the 100/30 or the 150/35 you need 6AWG to safely pass 30A or 35A over 20'. If you go to the 100/50 then you want 4AWG to pass up to 50A over 20'. But the 100/50 only accepts up to 6AWG so I'm not sure how that works.
and here is for 1S4P: suggested 100|30 by calculator
where can i find the 37 amps?
