When you pro's talk, having solar panels sized to battery amp size, are you referring to total battery capacity or the 50% useable battery capacity? I am working on my Solar system, I have a total house bank of switch-able 410AH on Bank#1(GC2) and 170AH Bank#2 (Group24). I plan on installing 5 X 120watt panels. I figure this should work good. Is my plan good? Thanks Gary
Bank1, 410Ah*14.5Volts*(1/0.77)panel+CC derating*0.05 rate of charge = 386 watts
Bank2, 170Ah*14.5*(1/0.77)*0.05 = 160 watts
Total watts required is 546, so your planned 600 watts is good.
