4.2.2 Solar Panel (PV) Connection
- Connect the solar panel array to the PV input terminals. Ensure the total PV open circuit voltage does not exceed 500V DC.
- The maximum PV input power is 6000W.
- Verify correct polarity before connecting.
4.2.3 AC Input/Output Connection
- Connect the AC grid input (220V/230V AC) to the AC input terminals.
- Connect your loads (appliances) to the AC output terminals. The inverter provides a 220V/230V AC pure sine wave output.
- Ensure all AC connections are properly grounded.
5. Operating Instructions
5.1 Powering On/Off
- To Power On: Ensure all connections are secure. Turn on the battery breaker first, then the AC input breaker (if connected), and finally the PV input breaker (if connected). Press the power button on the inverter.
- To Power Off: Disconnect AC loads. Turn off the PV input breaker, then the AC input breaker, and finally the battery breaker. Press and hold the power button until the inverter shuts down.
