Install Video etc. show only Panel and Battery Terminals being used. What is the Solar Appliances circuit intended for? I can break out circuits easily. Thanks !!! Robert

Hey Robert, glad to hear the project is coming together!
Great question on the etrailer PWM Solar Charge Controller # e42PR , those “Solar Appliance” aka 12V appliance terminals are essentially a load output from the controller.
They’re designed to power small 12V DC devices directly from the controller, rather than wiring those loads straight to the battery. They’re typically intended for lower-draw items like lights, small fans or USB chargers.
You’d only use the 12V Appliance output if you specifically want built-in low voltage protection for a small dedicated circuit.
