3.1.2 Setting the Grid-tied ESS Mode

The grid-tied ESS has three main working modes: self-consumption, time-of-use,
and excess fed to the grid.
Self-Consumption

NO TE
● When the grid charging function is enabled, the surplus power generated by the inverter
without batteries can be used to charge the inverter connected to the batteries.
● The parameters of each battery need to be set separately. When the grid charging
function is enabled, the surplus power generated by one inverter can be used to charge
the other inverter.
NO TE
indicates a power cable,
wireless communication.
This mode applies to areas where the electricity price is high, or areas where
the FIT subsidy is low or unavailable.
Excess PV energy is stored in batteries. When PV power is insufficient or no PV
power is generated at night, batteries discharge to supply power to the loads,
improving the self-consumption rate of the PV system and the self-sufficiency
rate of residential energy, and reducing electricity costs.
In this mode, Maximum self-consumption is selected. By default, the charge
cutoff capacity is 100% and the discharge cutoff capacity is 0% for Huawei
LUNA2000 batteries. For details about how to change the charge or discharge
cutoff capacity, see
