priority at the same time.
•The loads will be supplied by the surplus solar production supplemented, if necessary
by the public electricity grid. The battery will be used only when the grid failure.
•If set zero feed-in, the system will not export power to grid when work on the mode
of self-use, self-define or backup. But a small amount of energy will still inevitably
be fed into grid due to unpredictable PV energy change and load fluctuations.
3.4.4 Off-Grid Mode
When operating in this mode, Photovoltaic and battery constitute a pure off-grid system,
the critical loads (EPS Loads) will be powered by PV production and if the PV production
is insufficient, battery will discharge to power the loads at the same time. (Battery is
necessary in this mode.)
•When battery is discharged to the DischargeEndSOC@EPS value, the inverter will
stop working and wait for the grid to recover or until there is sufficient power from
PV panels to charge the battery.
•If grid failure is a common occurrence in your area, it is recommended to adjust the
DischargeEndSOC@Grid higher to ensure there is more battery power available.
