4.2. Fasi di installazione

1. Montaggio: Choose a suitable location for mounting the inverter. Ensure it is a dry, well-ventilated area, away from direct sunlight and heat sources.
2. Collegamento della batteria: Connect the battery bank to the inverter's Battery Input terminals (10). Ensure correct polarity (+ to + and - to -). Use appropriate cable gauges for the current.
3. Collegamento del pannello fotovoltaico: Connect your solar panel array to the PV Input terminals (9). Ensure the PV input voltage (120V - 450Vdc) and power (max 5500W) are within the inverter's specifications. The best working voltage è 200-300V.
4. Connessione ingresso CA: Connect the utility grid or generator AC power to the AC Input terminal (7).
5. Collegamento di uscita CA: Connect your AC loads (e.g., oven, rice cooker, lamps, TVs, fans) to the AC Output terminal (8).
6. Comunicazione (opzionale): If using, connect RS232/RS485 communication cables (12) or the optional WiFi monitoring module.
7. Accensione iniziale: Once all connections are secure, switch on the circuit breaker (11), then the Power On/Off switch (6) on the inverter.

5. Istruzioni per l'uso

The PMSUN 4500W Hybrid Inverter offers multiple charging and output modes to suit various application requirements. Use the touch buttons (5) and LCD display (1) to configure settings.

5.1. Modalità di ricarica

The inverter supports four optional charging modes:

• Solo solare: Carica le batterie esclusivamente tramite energia solare.
• Prima la rete elettrica: Prioritizes charging from the utility grid, supplementing with solar if needed.
• Solar First: Prioritizes charging from solar power, supplementing with grid if needed.
• Rete elettrica e solare ibrida: Utilizes both mains and solar power for charging simultaneously.

5.2. Modalità di uscita

Three output modes are available for power supply:

• Solar First: Prioritizes power from solar, then battery, then grid.
• Prima la rete elettrica: Dà priorità all'energia proveniente dalla rete elettrica, poi all'energia solare e infine alla batteria.
• Priorità SBU: Solar (S), Battery (B), Utility (U) - prioritizes solar, then battery, then utility grid.

The default mode is Off-Grid. You can manually activate On-Grid mode if desired. The AC output voltage can be adjusted to 110Vac or 220Vac in battery mode.

5.3. Lithium Battery Activation

The inverter includes a built-in BMS function with a reactivation feature to wake up sleeping lithium batteries.

5.4. Automatic Restart

The inverter supports automatic restart upon AC recovery, ensuring continuous power supply.
