4. Operating Instructions

Once installation is complete and all connections are verified, you can begin operating your system.

4.1. Initial Startup

1. Ensure all circuit breakers and disconnect switches are in the OFF position.
2. Connect the battery circuit breaker (if external) or switch on the battery.
3. Switch on the solar panel DC disconnect switch.
4. Switch on the grid AC input breaker (if connected to the grid).
5. Finally, switch on the inverter's AC output breaker.
6. Observe the inverter's display for status indicators and ensure it initializes correctly.

4.2. Inverter Display and Settings

The inverter features a display for monitoring system performance and adjusting settings. Refer to the inverter's specific manual for detailed navigation and parameter adjustments.

• Monitoring: View real-time data such as PV input voltage/current, battery state of charge, AC output power, and grid status.
• Operating Modes: Configure the inverter's operating mode (e.g., self-consumption, battery priority, grid-tie with backup) based on your energy needs and local regulations.
• Battery Parameters: Adjust charging and discharging parameters for the LiFePo4 battery as recommended by the battery manufacturer.
