4.2 Controller Connection

Follow these steps to connect the solar panel to the controller and then to your battery:

1. Connect the Battery First: Connect the alligator clips (output clip) to your 12V or 24V battery terminals. Ensure correct polarity: red to positive (+), black to negative (-). Then, connect the other end of the alligator clip cable to the DC output port on the solar charge controller.
2. Connect the Solar Panel: Connect the DC output cable from the 50W solar panel to the solar input port on the charge controller.
3. Optional: Car Charging Cable: If charging via a car's cigarette lighter, connect the car charging cable to the controller and then to the vehicle's cigarette lighter socket.

Important: Always connect the battery to the controller before connecting the solar panel. Disconnect in the reverse order: solar panel first, then battery.
