5.2 Installation Steps
- Connect the Battery First: Always connect the battery to the controller first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12V or 24V).
- Connect the Solar Panel: After the battery is connected, connect the solar panel array to the controller. Ensure correct polarity. Do not connect the solar panel before the battery.
- Connect the DC Load: Connect your DC loads (e.g., DC lights, fans) to the load terminals. Ensure correct polarity.
- Connect the Inverter (Optional): If using an inverter for AC loads, connect it directly to the battery terminals, not to the controller's load terminals. Ensure the inverter's input voltage matches the battery voltage.
Important Safety Notes:
- Do not connect the solar panel before connecting the battery.
- Do not connect inverters or inductive loads to the controller's load output. Connect them directly to the battery.
- Ensure the battery voltage is sufficient (typically >9V) for the controller to operate.
- Do not exceed the maximum input power/voltage of the controller.
- Install appropriate fuses between the battery and the controller, and between the battery and the inverter, for safety.

10. Troubleshooting
This section addresses common issues you might encounter with your solar charge controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | Battery not connected or low voltage; reverse polarity. | Ensure battery is connected first with correct polarity. Check battery voltage (must be >9V). |
| No charging from solar panels | Solar panels not connected; incorrect polarity; insufficient sunlight; PV voltage too low/high. | Verify solar panel connections and polarity. Check for shading. Ensure PV voltage is within specifications (18V-96V for 12V system, 36V-96V for 24V system). |
| Load not working | Load output disabled; battery low voltage; overload; short circuit. | Check load settings on LCD. Ensure battery voltage is above low voltage disconnect threshold. Reduce load or check for short circuits. |
| Inaccurate voltage readings | Loose connections; faulty sensor. | Check all wiring connections. If using a remote temperature sensor, ensure it is properly connected. |
| Controller overheating | Poor ventilation; excessive load. | Ensure adequate airflow around the controller. Reduce load if consistently overheating. |
