What Is The Standard For The Specification And Wire Diameter Of The Fuse Used Between The Battery And The Controller?

By Renogy User Experience Team Apr 20th 2023

The specification of the fuse between the battery connected to the controller is the maximum output current of the controller as the reference. The selection of wire diameter is based on the maximum output current of the controller, and is calculated according to the wire diameter current-carrying table. For example, If you have a 30A controller fully loaded, the fuse should also be 30A.
