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.
Typically used between series connected solar panels and a charge controller.
Typically used between a combiner box and a charge controller in 30A (or 400W) or smaller systems

Typically used between a combiner box and a charge controller in 25A-35A (or 300W-500W) systems
Sold by the foot
Typically used between a combiner box and a charge controller in 40A-60A (or 600W-800W) systems

Typically used between a combiner box and a charge controller in 70A (or 900W) or larger systems.

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.
*Color may vary based on availability. This will have no effect on performance.*
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.
Continuous Rating: 300A
Intermittent Rating: 500A (5 min)
Maximum Voltage: 48Vdc
Dimensions: 2 7/8"H x 2 7/8"W x 3 1/4"D
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"
Maxi Fuses provide circuit protection typically between a charge controller or small inverter and a battery bank
ATC Fuses are commonly used in automotive applications between the battery bank and DC loads like lights and fans.
