4. Impostazione
4.1 Selezione del sito
- Mount the inverter indoors, away from direct sunlight, rain, and moisture.
- Ensure ambient temperature is between 0°C and 55°C (32°F and 131°F).
- Maintain at least 20 cm (8 inches) clearance around the inverter for proper airflow.
- The mounting surface must be strong enough to support the inverter's weight (approximately 59.4 lbs).
4.2 Montaggio dell'inverter
- Mark the positions for the mounting screws on the wall.
- Se necessario, praticare dei fori e inserire i tasselli a muro.
- Securely mount the inverter to the wall using appropriate screws.
4.3 Collegamenti di cablaggio
IMPORTANT: All wiring must comply with local and national electrical codes. Ensure all connections are tight and secure.
- Collegamento della batteria: Connect the 48V battery bank to the inverter's battery terminals. Ensure correct polarity (positive to positive, negative to negative). Use appropriate cable gauges and fuses/breakers.
- Collegamento del pannello fotovoltaico: Collegare il pannello solare ai terminali di ingresso del pannello fotovoltaico. Verificare che la tensione a circuito aperto del pannello fotovoltaicotage (Voc) does not exceed 150Vdc and the MPPT voltage range is 60~150Vdc. Ensure correct polarity.
- Connessione ingresso CA: Connect the utility grid or generator AC power to the AC input terminals. Install an external circuit breaker for protection.
- Collegamento di uscita CA: Connect your AC loads to the AC output terminals. Install an external circuit breaker for protection.
- Messa a terra: Collegare il terminale di terra dell'inverter a una messa a terra affidabile.
