5. Configurazione e installazione
5.1 Scelta del luogo di installazione
Seleziona una posizione che sia:
- Asciutto e ben ventilato.
- Lontano dalla luce solare diretta e da fonti di calore.
- Secure and stable to prevent movement.
- Accessibile per collegamenti e manutenzione.
5.2 Collegamento della batteria
Ensure the inverter is turned OFF before making any connections.
- Connect the positive (+) red battery cable to the positive (+) terminal of the inverter.
- Connect the negative (-) black battery cable to the negative (-) terminal of the inverter.
- Connect the other end of the positive (+) red battery cable to the positive (+) terminal of your 12V battery.
- Connect the other end of the negative (-) black battery cable to the negative (-) terminal of your 12V battery.
- Ensure all connections are tight to reduce resistance and prevent overheating.

6. Funzionamento
6.1 Accensione/Spegnimento
- To turn ON the inverter, ensure all connections are secure, then flip the main ON/OFF switch on the inverter to the 'ON' position. If using the remote, ensure the main switch is OFF, then use the remote switch.
- The LCD display will illuminate, showing output wattage, volume della batteriatage altri indicatori di stato.
- To turn OFF the inverter, flip the main ON/OFF switch to the 'OFF' position or use the remote switch.
6.2 Collegamento dei dispositivi
Once the inverter is powered on, you can connect your AC devices to the dual AC outlets. For charging USB devices, use the USB or Type-C ports.
- Garantire l'acqua totaletage of all connected devices does not exceed the inverter's continuous output rating of 2000W.
