4. Setup and Connection
Follow these steps carefully to connect your MPPT solar charge controller to your solar panel, battery, and DC load. The correct connection order is critical to prevent damage to the controller and other components.
- Connect the Battery: First, connect the battery to the controller's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the battery voltage.
- Connect the DC Load: Next, connect the DC load to the controller's load terminals. Ensure correct polarity.
- Connect the Solar Panel: Finally, connect the solar panel to the controller's solar panel terminals. Ensure correct polarity.
Important: Always connect the battery first, then the load, and finally the solar panel. Disconnect in the reverse order: solar panel, then load, then battery.

8. Troubleshooting
If you encounter issues with your solar charge controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/No power | Battery not connected or low voltage; loose connections. | Check battery connections and voltage. Ensure battery voltage is above the minimum operating threshold. |
| Battery not charging | Solar panel not connected; insufficient sunlight; faulty solar panel; incorrect settings. | Verify solar panel connections and ensure adequate sunlight. Check solar panel output voltage. Review charging mode settings. |
| Load not working | Load not connected; battery voltage too low (low voltage disconnect); load mode incorrect; overload protection activated. | Check load connections. Allow battery to charge. Verify load operating mode. Reduce load to prevent overload. |
| Over-temperature warning | Poor ventilation; excessive ambient temperature; heavy load. | Ensure adequate ventilation around the controller. Reduce ambient temperature if possible. Reduce load. |
If the problem persists after attempting these solutions, please contact customer support.
