5. Configuració i instal·lació
Segueix aquests passos per a una instal·lació correcta del teu controlador de càrrega solar:
- Preparació dels components: Ensure you have your solar panel, battery (12V/24V lead-acid: OPEN, AGM, or GEL), and appropriate cables.
- Connecteu primer la bateria: Connect the battery to the charge controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will detect the battery voltage (12V o 24V).
- Connecteu el panell solar: Connect the solar panel to the charge controller's solar panel terminals. Ensure correct polarity. The controller will begin charging the battery.
- Connect Load (Optional): If you have a DC load, connect it to the load terminals on the controller. Ensure correct polarity.
- Verifica les connexions: Double-check all connections for tightness and correct polarity before powering on the system. Loose connections can cause damage.
Consideracions importants:
- Install the controller in a dry, well-ventilated area, away from direct sunlight and moisture.
- Ensure battery cables are as short as possible to minimize voltage gota.
- Do not connect any other charging source (e.g., AC charger, generator) directly to the controller's solar input terminals.
