For use with either of the Morningstar Tristar charge controllers, the resistor is effectively a very high power air heating element. The TS-45 and TS-60 charge controllers are used in “Diversion & Charge Control” mode with dump loads/resistors, and as such, they dissipate any unwanted power into the resistor when your battery bank becomes fully charged. It is vital to use a charge controller to prevent damage to your batteries, especially if you leave your system unattended for long periods of time, and without loading your batteries with an inverter, or other suitable device.
The resistor should be mounted as close as possible to your TS-45 or TS-60 charge controller. It should be mounted in free circulating air and not in an enclosed space. The power connections are located on the resistor. Please ensure you order the correct resistor to suit your system.
