Using 7 flat vs 8 aimed ratio (based on some tests I did in May at 49N)
for amps output at high noon starting with aimed--
510w with 10% heat loss = 459w with say 2% line loss array to controller= 450w input with say 5% controller loss = 428w output. Amps to battery is output watts/battery voltage, so: (with no line loss controller to battery)
428/12.5 = 34.2a and 7/8 of that is 30 amps estimated
428/13.5 = 31.7a and 7/8 of that is 28 amps estimated
