5.2 Installation Steps
Follow these steps for proper installation. Ensure all power sources are disconnected before making any connections.
- Mounting the Controller: Choose a dry, well-ventilated location, preferably indoors, away from direct sunlight and moisture. Mount the controller vertically on a wall or suitable surface using appropriate fasteners. Ensure adequate clearance around the unit for proper heat dissipation.
- Connecting the Battery: Connect the battery to the controller's battery terminals (marked 'BATTERY' or with battery symbols). Ensure correct polarity: positive to positive, negative to negative. This connection must be made first to allow the controller to detect the system voltage.
- Connecting the Solar Panels: Connect the solar panel array to the controller's PV input terminals (marked 'SOLAR PANEL' or with PV symbols). Ensure correct polarity. Verify that the open-circuit voltage (Voc) of your solar array does not exceed the controller's maximum PV input voltage (DC150V).
- Connecting the DC Load (Optional): If you are connecting a DC load directly to the controller, connect it to the DC load output terminals (marked 'DC LOAD' or with load symbols). Ensure correct polarity. Note that the load output is typically for smaller DC loads and may have current limitations.
- Connecting the Temperature Sensor (Optional): If included, connect the external temperature sensor to the designated port (marked 'TEMP SENSOR'). This allows the controller to adjust charging parameters based on battery temperature for optimal performance and lifespan.
- Power On: Once all connections are secure and verified, the controller will power on automatically. The digital display will illuminate, showing current system parameters.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller.
- Cleaning: Periodically clean the controller's exterior with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
- Connection Check: Annually inspect all wiring connections for tightness and corrosion. Loose connections can cause overheating and poor performance.
- Environmental Check: Ensure the installation environment remains dry and within the specified operating temperature range.
- System Monitoring: Regularly check the digital display for any error codes or unusual readings.
8. 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; reversed battery polarity. | Ensure battery is connected first and has sufficient voltage. Check battery polarity. |
| No PV input/charging | Solar panels not connected; reversed PV polarity; insufficient sunlight; PV voltage too low/high. | Check PV connections and polarity. Ensure adequate sunlight. Verify PV voltage is within controller's operating range. |
| Load not working | Load output disabled; overload; short circuit; reversed load polarity. | Check load settings on display. Reduce load. Check for short circuits. Verify load polarity. |
| Overheating warning | Poor ventilation; excessive ambient temperature; prolonged high current operation. | Improve ventilation around controller. Reduce load if possible. Ensure ambient temperature is within limits. |
