Operating states
(only for systems
with a battery)
Battery systems distinguish different operating states. In this case, the relevant current
operating state is displayed on the website of the inverter or in Solar.web.
Operating state Description
Normal operation Energy is stored or drawn, as required.
Min. state of charge (SOC)
achieved
Battery has reached the minimum SOC set or specified
by the manufacturer. The battery cannot be discharged
any further.
Energy saving mode
(standby)
The system has been put into energy saving mode.
Energy saving mode is automatically ended as soon as
sufficient excess energy is available again.
Start
The storage system starts from energy saving mode
(standby).
Forced re-charging
The inverter re-charges the battery, in order to maintain
the set minimum SOC (state of charge) or the SOC
specified by the manufacturer (protection against deep
discharge).
Deactivated
The battery is not active. It has either been deactiv-
ated/switched off, or an error means that no commu-
nication with the battery is possible.
