Sunny Backup- Set S
Reliable back-up electricity supply for single-family homes
Innovative power backup for private homes: as an add-on to the 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, if the power goes out, owners of small to medium-sized PV plants and inverters from SMA can supply their most important consumer loads themselves. Our affordable complete solution is suitable for both new solar electricity systems as well as existing PV plants, which can be easily retrofitted with our certified Sunny Backup Set S.
