5. Configuració i instal·lació

Proper installation is crucial for the optimal performance and longevity of your solar charge controller. Follow these steps carefully:

1. Connecteu primer la bateria: Connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will detect the battery voltage (12V or 24V) automatically.
2. Connecteu els panells solars: Connect the solar panels to the charge controller. Again, observe correct polarity.
3. Connect DC Load (Optional): Connect your DC load (e.g., DC lights) to the load terminals of the controller.
4. Connect Inverter (Optional): If using an inverter for AC loads, connect it to the battery terminals (not directly to the controller's load terminals).

Important: Always connect the battery to the controller first, then the solar panels, and finally the load. Disconnect in the reverse order: load, then solar panels, then battery.
