Title
Figure 21. Eaton xStorage Home 3P self-consumption mode during the night
In the absence of energy from the photovoltaic
system, the battery is discharged to supply domestic
loads. If the energy required by the loads is higher
than the energy stored the battery, the remaining
part is taken from the grid. The energy stored in the
battery usually does not feed in to the grid and it is
used to supply the home loads.
4.2.2 “FEED-IN CONTROL” Mode
This operating mode is mainly indicated in installations where local regulations require a limitation on
the energy that is injected in to the grid.

In the presence of sunshine, the energy from the
photovoltaic system is used primarily to supply the
domestic loads and secondly to charge the battery.
Further energy in excess is transferred to the grid
with the possibility to set a limit on the value of the
maximum power fed into the grid. If the set limit
is zero and there is no demand for energy from
the loads, the inverter will limit the input power
to the set value by reducing the production of the
photovoltaic energy until it completely inhibits it.
Therefore, by setting the input limit to 0 W, the
system will totally prevent the transfer of energy
to the grid. Moreover, If the energy required by
the loads is high and the available energy from
photovoltaic field and battery is not enough, the
remaining part is taken from the grid.
