In the off-grid state, the output phases of cascaded inverters are different. The
load outputs of the Backup Boxes connected to each inverters cannot be
connected in parallel. As shown in the following figure, the P-1 output is
connected to primary O-1 and the P-2 output is connected to O-2. The P-1 and
P-2 load outputs cannot be connected in parallel.

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. When the grid recovers, the ESS automatically switches
back to the grid-tied mode.
