3.3.2 Setting the Pure O-grid ESS Mode
The inverter works in o-grid mode. When the sunlight is sucient, the ESS
supplies power to loads and stores surplus PV energy in batteries. When the
sunlight is
insucient or there is no sunlight, the batteries discharge to supply
power to loads. By default, the charge cuto capacity of Huawei LUNA2000
batteries is 100% and the discharge
cuto capacity is 0%. For details about how
to change the charge or discharge cuto capacity, see 6.3 Battery
Commissioning. In o-grid mode, you need to set the o-grid power grid code on
the Quick setting screen.
