Parameter

Description

Off-grid mode

If this parameter is set to Enable, the ESS switches to the off-grid mode 

when the grid fails.

Backup power SOC

Sets the backup power SOC. In grid-tied mode, the battery does not 

discharge when it is discharged to the backup power SOC. When the grid 

fails, loads are powered in backup mode.

Grid-tied/Off-grid 

mode switching

If this parameter is set to Automatic switching, the system switches to the 

off-grid mode when the grid fails, and switches to the grid-tied mode when 

the grid recovers.

Voltage in 

independent 

operation

Select the voltage in independent operation based on the inverter cable 

connection, 101 V or 202 V.

Creating a Plant

7.3.4

After the connection management status on the SmartLogger WebUI is successful, log in to the 

FusionSolar app and create a PV plant.
