and will stay into that status until
SOC
passes “
SOC Rec
” value.
The AC generation process will be stopped if the inverter is in the
“Empty battery”
status and
the system detects that there is no surplus energy in the solar panels.
The AC generation process will perform periodic start-up attempts to detect possible photovol-
taic energy surpluses.
Between
SOC Min
and
SOC Rec
, it will use the energy of the solar panel to charge the battery
and, if there is surplus solar energy, the AC generation option will be activated and used to
cancel the loads.
Discharging the battery will be allowed after reaching
SOC Rec
value.
Energy from solar panels will be used:
To cancel the loads power consumption (direct and external),
If there is an excess, to charge the battery,
Energy from batteries will be used:
To cancel the loads power consumption, if there is not enough PV generation, and the bat-
tery is not in “
empty battery
” state.
In case of grid failure, the supply of direct loads will depend on the status of the battery (
SOC
),
and will have the same behaviour as described in the “
Off-Grid”
mode. (“
7.2.1.1.- Off-Grid”
)
In case of grid failure, the device will open the grid relays, won’t take into account the external
loads, and will cancel only the direct loads power consumption.

Depending on the
SOC
of the battery, the inverter will charge the batteries or will feed into the
grid, looking for a simple management that will guarantee maximum autonomous operation in
Off-Grid mode, trying to avoid limiting PV generation.

Energy from solar panels will be used:
To charge the battery;
If there is an excess, it will be fed into the grid.
