5. Installation and Setup
Proper installation is crucial for the performance and safety of your solar power system. Follow these steps carefully:
5.1 Mounting the Controller
- Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and moisture.
- Ensure there is sufficient clearance around the controller for proper airflow, especially for the cooling fan.
- Mount the controller vertically on a non-flammable surface using appropriate fasteners.
5.2 Wiring Connections
Important: Always connect the battery first, then the solar panel. Disconnect in the reverse order (solar panel first, then battery).
- Connect the Battery: Connect the positive and negative terminals of your battery bank to the corresponding 'BATTERY' terminals on the controller. Ensure correct polarity.
- Connect the Solar Panel: Connect the positive and negative terminals of your solar panel array to the corresponding 'SOLAR PANEL' terminals on the controller. Ensure correct polarity.
- Connect Temperature Sensor (Optional): If using, connect the temperature sensor to the 'TEMP' port. This allows the controller to adjust charging parameters based on battery temperature.
- Connect RS485 Communication Line (Optional): If using, connect the RS485 communication line for external monitoring or control.
