Energy saving mode
General Energy saving mode (standby) is used to reduce the self-consumption of the sys-
tem. It is available from version 1.4.1-11 of the system monitoring software. Both
the inverter and the battery automatically switch into energy saving mode under
certain conditions.
Fronius Symo Hybrid
If the battery is flat and no PV energy is available, the inverter switches to energy
saving mode. Only the inverter's communication with the Fronius Smart Meter
and Fronius Solar.web is maintained.
Fronius Solar Battery
When the battery is in energy saving mode, the display remains dark. In Sol-
ar.web, energy saving mode is indicated by an "i" next to the battery symbol. In
the energy balance view, the SOC (State of Charge) of the Fronius Solar Battery
is not displayed for the duration of energy saving mode.
BYD Battery-Box Premium
In Solar.web, energy saving mode is indicated by an "i" next to the battery sym-
bol.

Hybrid switch-
off conditions
The battery state of charge is less than or equal to the input
minimum state of charge.
The power from the PV modules is less than 50 W.
The current charging or discharging power of the battery is
less than 100 W.
Less than 50 W is available for charging the battery. The
power of feeding in for the public grid is at least 50 W less
than the power currently required in the home network.
If all the switch-off conditions are met, the battery switches into energy saving
mode within six minutes. This time delay ensures that the inverter can be restar-
ted at least once.
The inverter automatically switches into energy saving mode after the battery.
Backup power:
If the backup power function has been activated, the battery in grid operation
does not switch to energy saving mode. Otherwise, the dark start (start without
grid and PV supply) of the hybrid system cannot be ensured.
During backup power mode and when the state of charge falls below the minim-
um limit, the battery switches to energy saving mode.
