Figure 3-8 Inverter (with batteries) + Inverter (without batteries)
When the inverter switches to the off-grid state, different output primary loads of the Backup
Box cannot be connected in parallel due to different output phases of off-grid inverters.
Therefore, the primary loads must be connected to different buses.

3.2.2 Setting the Grid-tied and Off-grid ESS Mode

The grid-tied and off-grid ESS switches the inverter to the grid connection status through the
Backup Box. When the grid fails, the ESS supplies power to primary loads in backup mode.

This mode can be used together with the self-consumption or time-of-use mode.
− When the grid is normal, the self-consumption or time-of-use mode is used.
After the grid fails, the ESS switches to the power backup mode. The battery
−
backup time depends on the battery SOC when the grid fails. (The battery SOC for
power backup can be set based on customer requirements.)
