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.

Duplex-10/2 600V Cable

Disconnect Switches & DC Breakers

A disconnect switch is typically installed on the positive line, between the combiner box and the charge controller.  The breaker or fuse is installed on the positive line between the charge controller and the battery bank.

High Current On/Off Switch
37.50

Manually disconnect high current lines.  This switch is typically used between a combiner box and a charge controller, or between a battery bank and an inverter.

Dimensions: H 3.4" x W 2.9" x D 2.9"

DC Breakers
from 57.50

Because of Direct Current's tendency to arc when disconnected, special breakers are needed.  These DC breakers are ideally used between charge controllers and battery banks and on alternator or small inverter lines.

Dimensions: H 1.8" x W 2.3" x D 3.5"
