System Core Components

Wire Harnesses

System Cores without charge controllers include the wire harness and circuit protection for feeding power from solar panels onto battery banks. Just add an appropriate charge controller of your choosing.

Roof to Charge Controller Cable

The cable between the combiner box, charge controller and battery bank needs to be thick enough to handle combined current of the entire solar array. Thicker cable means less voltage drop.
