4. Configuració i instal·lació
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Refer to Figure 2 for terminal identification.
Passos d'instal·lació:
- Muntatge: Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and moisture. Ensure adequate clearance around the controller for air circulation, especially for the cooling fan. Use the mounting holes provided to secure the controller to a stable surface.
- Connexió de la bateria: Connect the battery cables to the battery terminals on the controller (marked with '+' and '-'). Ensure correct polarity. Connect the other end of the cables to your battery bank. Always connect the battery first.
- Connexió del panell solar: Connect the solar panel cables to the PV terminals on the controller (marked with '+' and '-'). Ensure correct polarity. Connect the other end of the cables to your solar panel array.
- Connexió de càrrega (opcional): If you are connecting a DC load directly to the controller, connect the load cables to the load terminals (marked with '+' and '-'). Ensure correct polarity.
- Connexió del sensor de temperatura: Connect the included temperature sensor to the designated 'TEMP SENSOR' port. Place the sensor near the battery to ensure accurate temperature compensation for charging.
- Encès: Once all connections are secure and verified for correct polarity, the controller will power on and display information on the LCD screen.
Tipus de bateries compatibles:
The controller supports various battery types. Ensure you select the correct battery type in the controller settings for proper charging and protection.
