Fusing; Technical Specifications; Electrical Parameters - Renogy ROVER Serie Installation

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.

Current
The NEC code requires the overcurrent protection shall not exceed 15A for
NOTE
14AWG, 20A for 12 AWG, and 30A for 10AWG copper wire.
Controller to Battery Fuse = Current Rating of Charge Controller
Different safety factors could be used. The purpose is to oversize.
NOTE
Total Amperage= Isc1 = Isc2 * SF
= 5.75A * 1.56 = 8.97
Fuse = 9A fuse
