xample of Self-Consumption
Examples of self-consumption:
(1) When the sunlight is sucient, the PV module outputs 8 kW power, the
inv
erter 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.
Time-of-Use
● This mode applies to scenarios where the price dierence between peak and
o-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 6.3 Battery Commissioning.
