4. Installation and Wiring

Proper installation is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully.

4.1 Connection Sequence

Always connect components in the following order to prevent damage:

1. Connect the battery: Connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The battery terminals should be installed with safety fuses. Ensure the distance does not exceed 150mm.
2. Connect the load: Connect your DC loads to the controller's load terminals.
3. Connect the solar panel: Connect the solar panel to the controller's solar energy terminals. Ensure correct polarity.
4. Power on the controller: The controller will automatically power on once all connections are secure.

Note: If you want to connect an inverter, connect it directly to the battery, not to the load terminal of the controller.
