4. Istruzioni per l'installazione

1. Disimballare e ispezionare: Carefully remove all components from the packaging. Inspect the solar panel and cables for any visible damage.
2. Scegli il metodo di connessione: The charger comes with three types of connection cables:
   • Batteria Clamp Cavo: For direct connection to battery terminals (red to positive, black to negative).
   • Cavo accendisigari: For connecting to a vehicle's 12V cigarette lighter socket.
   • Bare Wire Cable: For custom installations where direct wiring is preferred.
3. Collegamento alla batteria: Select the appropriate cable and connect it to your 12V battery. Ensure correct polarity (red to positive '+', black to negative '-'). Incorrect polarity will trigger a solid red error light.
4. Collegare il pannello solare: Plug the chosen connection cable into the solar panel's output port.
5. Posizione del pannello solare: Place the solar panel in a location that receives maximum direct sunlight throughout the day. The panel is designed to work even in cloudy conditions, but direct sunlight will yield the best charging results.

5. Istruzioni per l'uso

Once properly set up and exposed to sunlight, the solar charger will automatically begin charging and maintaining your 12V battery. Observe the LED indicator for operational status:

• Blink Green: Indicates that the solar panel is effectively receiving sunshine and generating power.
• Lampeggia in rosso: Indicates that the charger is actively working to charge the battery.
• Verde pieno: Indicates that the battery is fully charged. The charger will automatically stop charging to prevent overcharge and switch to maintenance mode.
• Rosso pieno: Indicates an error, most commonly a reversed connection (incorrect polarity). Disconnect immediately and re-connect with correct polarity.

The intelligent charge controller ensures that your battery is charged safely and efficiently, preventing overcharging and extending its lifespan. The charger will automatically resume charging if the battery voltage scende al di sotto di un certo livello.

6. Manutenzione

• Pulisci il pannello: Pulire periodicamente la superficie del pannello solare con un panno morbido eamp cloth to remove dust, dirt, or debris that may reduce efficiency. Do not use abrasive cleaners.
• Controllare le connessioni: Controllare regolarmente tutti i collegamenti dei cavi per assicurarsi che siano saldi e privi di corrosione.
• Magazzinaggio: When not in use for extended periods, store the solar charger in a cool, dry place away from direct sunlight and extreme temperatures.

7. Risoluzione Dei Problemi

• LED rosso fisso: This indicates a reversed polarity connection. Immediately disconnect the solar panel from the battery and re-connect ensuring the red cable is attached to the positive (+) terminal and the black cable to the negative (-) terminal.
• No LED Indication / Not Charging:
  • Assicurarsi che il pannello solare riceva sufficiente luce solare diretta.
  • Controllare che tutti i collegamenti dei cavi non siano allentati o danneggiati.
  • Verify that the battery is a 12V battery and is capable of accepting a charge.
  • Inspect the cables and the solar panel for any physical damage.
