40 Amp Relay

Expand your charge controller and handle more amps!

The 40-Amp Relay can be used to increase the Amperage handling capacity of a WindyNation 40 to 120-Amp Dump/Diversion Charge Controller.

One 40-Amp relay will allow you to increase the amp capacity of your charge controller to 80 Amps. By using two 40-Amp relays, you can increase the amp capacity to 120 amps!
