● 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

– 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.)
