**Utilize 1.56 Sizing Factor (SF)
Different safety factors could be used. The purpose is to oversize.
Series:
Total Amperage= Isc1 = Isc2 * SF
Parallel
Total Amperage= (Isc1 + Isc2) * SF
The NEC code requires the overcurrent protection shall not exceed 15A for
14AWG, 20A for 12 AWG, and 30A for 10AWG copper wire.
NEC Maximum Current for different Copper Wire Sizes
Fuse from Controller to Battery
Fuse from Solar Panel(s) to Controller
Ex. 200W; 2 X 100 W panels
Ex. 20A MPPT CC = 20A fuse from Controller to Battery
Controller to Battery Fuse = Current Rating of Charge Controller
= 5.75A * 1.56 = 8.97 =(5.75A + 5.75A)* 1.56 = 17.94
Fuse = 18A fuse Fuse = 9A fuse
NOTE
Fusing is a recommended in PV systems to provide a safety measure for connections going from
panel to controller and controller to battery. Remember to always use the recommended wire
gauge size based on the PV system and the controller.
