3. Configuració i instal·lació
Proper connection order is crucial for the correct functioning and safety of the solar charge controller. Follow these steps carefully:
- Connecteu la bateria: First, connect the battery to the charge controller. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the battery voltage (12V o 24V).
- Connecteu els panells solars: Next, connect the solar panels to the charge controller. Again, observe correct polarity.
- Connecteu la càrrega de CC (opcional): Finally, connect any DC loads (e.g., lights, fans) to the load terminals of the controller.
Nota important: The controller will not function if connections are made in an incorrect order. Only 12V batteries will power a 12V panel, and a 24V panel requires a 24V battery for proper operation.
