Sunny Backup Set S
Reliable back-up electricity supply for family homes
Innovative power backup for private homes: as an add-on to a PV plant, the Sunny Backup Set S switches
automatically to off-grid mode within 50 milliseconds in the event of grid failure. Whether in summer or winter:
owners of small to mid-sized SMA PV plants and inverters can supply their most important consumer loads
themselves in case of a blackout. Our affordable complete solution is suitable for both new solar electricity
systems as well as existing PV systems, which can be easily retrofitted with our certified Sunny Backup Set S.
Existing PV plants can also be retrofitted with this certified Sunny Backup Set S without problems.
