9 Operation
9.1.3 Discharge operating status
Figure 46: Discharge
Discharge delivers energy stored in the
battery into the home network. The
power cannot exceed the consumption
required in the household. If the
battery is unable to serve the entire
home consumption, the remainder
comes from the public grid.
9.2 Operating mode
►
The storage system controls the energy flow and thus the operating status in
the household depending on the activated operating mode.
►
For continuous operation select „automatic mode“.
9.2.1 Automatic mode
In automatic mode the storage system automatically changes to the right operating
status. The basis for control in automatic mode is continuous measurement of
consumption and generation. If generation exeeds consumption for a certain time,
the battery commences charging of free capacity. Depending on the setting the
consumer connected by the self-consumption switch is additionally cut in. Also,
depending on the setting, the optional wireless socket outlets can be cut in. Once
the storage system is fully charged, it changes to standby status. Surplus energy is
fed into the public grid.
If generation is less than consumption, the battery switches to discharge. This is
only an amount needed in the household. Note that necessary switching times of
the system can lead to slight controlling delays.
Energy management in automatic mode
In automatic mode all energy flows are controlled automatically. Depending on
generation the storage system switches between charge and discharge.
While energy is being generated it is distributed with the following priority:
1. Consumers in household
2. Charging of storage system
3. Feed-in to grid
While there is no generation (e.g. nighttime) the consumers in the household are
supplied by the storage system up to maximum battery capacity. Extra energy
needed is imported from the public grid.
