When selecting the correct amperage rating for your in-line circuit breaker, first determine the
maximum current output of your solar panel array by adding up the current at maximum Power (Imp)
for each panel, then round up to the next standard amperage size.
Example: (3) 150watt panels, Imp = 8.5Amps ea. Total Imp. = 25.5Amps
Recommended fuse or circuit breaker size 30 Amps.
