Example of Self-Consumption
Examples of self-consumption:
(1) When the sunlight is sufficient, the PV module outputs 8 kW power, the
inverter outputs 5 kW power, the loads consume 4 kW power, and the batteries
charge 1 kW power.
(2) When the sunlight becomes weak, the PV module outputs 4 kW power, the
inverter outputs 2 kW power, the loads consume 4 kW power, and the batteries
discharge to supply 1 kW power to the loads.

Description
Set this parameter to the maximum self-
consumption mode.
Retain this parameter to the maximum
charge power. Additional configuration is
not required.
Retain this parameter to the maximum
discharge power. Additional configuration is
not required.
Set the charge cutoff capacity.
Set the discharge cutoff capacity.
This mode applies to scenarios where the price difference between peak and
off-peak hours is large.
In this mode, Time-of-use is selected. You can manually set the charge and
discharge time segments. For example, you can allow the grid to charge
batteries in low electricity price periods at night and discharge batteries
during high electricity price periods, saving electricity fee. The charge from
grid function must be enabled.
A maximum of 14 time segments can be set. For details about how to set
charge and discharge parameters, see
