SMA Energy System Home
In the SMA Energy System Home (storage system), the Sunny Island uses the
connected battery for the intermediate storage of excess PV energy for increased
self-consumption.
Battery-backup system
In the event of grid failure, a battery-backup system supplies loads with energy
and a PV system disconnected from the utility grid with voltage.
External energy source
Grid-forming generators such as electric generators or utility grids
Off-grid system
All components belonging to the stand-alone grid (e.g., Sunny Island)
Grid failure
Utility grid failure or deviation from the country-specific thresholds for voltage
and frequency
Automatic transfer switch with
battery-backup function
disconnects the battery-backup grid from the utility grid in the event of grid fail-
ure.
