To set up the SolaX Power X3-Hybrid G4 Series to supply electricity from the battery to the grid at a specific time or stop charging the battery and send excess to the grid, follow these steps:

1. Select the Appropriate Working Mode:
- Use the inverter LCD or the SolaX APP to choose a suitable working mode.
- The "Feed-in Priority" mode allows supplying electricity to the grid first.
- The "TOU (Time-of-Use)" mode enables setting specific time periods for charging and discharging.

2. Set Charging Periods and Battery SOC:
- Adjust the charging periods to control when the battery charges.
- Ensure the actual battery SOC minus the modified Min SOC is at least 2% for changes to take effect.

3. Confirm System Time and Mode Activation:
- Ensure the system time is correctly set for the new schedule to take effect.
- Once the set time is reached, the inverter will follow the configured mode to either discharge to the grid or stop charging.

For detailed settings, refer to the "User Setting" section in the manual.
