4. Setup & Installation

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

4.1 Mounting the Controller

• Choose a dry, well-ventilated location away from direct sunlight and heat sources.
• Ensure there is sufficient space around the controller for airflow, especially for the cooling fan.
• Mount the controller vertically on a sturdy surface using appropriate fasteners.

4.2 Wiring Connections

Connect the components in the following order: Battery → Solar Array → Load.

1. Connect the Battery: Connect the battery cables to the controller's battery terminals (+ and -). Ensure correct polarity.
2. Connect the Solar Array: Connect the solar panel cables to the controller's PV terminals (+ and -). Ensure correct polarity.
3. Connect the DC Load (Optional): If using a DC load directly from the controller, connect it to the load terminals (+ and -).

7. Troubleshooting

If you encounter issues with your PROSOLI 120A MPPT Solar Charge Controller, refer to the following common troubleshooting tips.

• No Display/Power: Check battery connections and ensure the battery voltage is within the operating range. Verify all fuses and circuit breakers.
• Battery Not Charging: Confirm solar panel connections and polarity. Check for sufficient sunlight. Verify battery type settings are correct.
• Error Codes: Consult the specific error code displayed on the LCD with the product manual for detailed explanations and solutions.
• Over-Temperature Protection: If the controller shuts down due to high temperature, ensure adequate ventilation and clean any dust from the cooling fins. The auto-restart function (if enabled) will reactivate the controller once the temperature normalizes.
