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

The inverter works in off-grid mode. When the sunlight is sufficient, the ESS
supplies power to loads and stores surplus PV energy in batteries. When the
sunlight is insufficient or there is no sunlight, the batteries discharge to supply
power to loads. By default, the charge cutoff capacity of Huawei LUNA2000
batteries is 100% and the discharge cutoff capacity is 5%. For details about how
to change the charge or discharge cutoff capacity, see
Commissioning. In off-grid mode, you need to set the off-grid power grid code
(Island-Grid) on the Quick setting screen.
