If the PV power is less than the load power, the battery will discharge and
provide the energy shortfall. The inverter will draw power from the mains if the
power from the PV and battery is less than the load power.
Energy Management during Night
The battery discharges to provide energy to loads. If the battery is empty or
there is not enough power from the battery system to supply active loads, the
unmet power will be supplied by the grid.
If the Energy Meter is abnormal or not equipped:
the inverter can run normally;
the battery can be charged, but not allowed to discharge;
the export power setting on the LCD screen will be ineffective;
the DO function of optimized mode will be disabled.
