Power outage means:

Disconnection of the PV system from the grid

No light, no heating, and no computer: today, it is very difficult to do anything without electricity. But how many solar power system operators are really aware that in the event of a power outage, the PV system is disconnected from the grid for reasons of safety? From the moment of disconnect, it ceases to provide solar power – neither for grid feeding, nor for the internal power supply. And this is all the more problematic, because experts agree: Throughout Europe, lengthy blackouts and temporary power outages are likely to increase.

Sunny Backup means:

Electricity – even in the event of grid failure

It is precisely this supply gap, which we are closing with the new Sunny Backup system from SMA. As of now, this can be used by any PV system owner to power important loads in a reliable and environmentally friendly way, even in the event of grid failure. Within just 20 milliseconds (SBU 2200 = 50 ms), the system switches to a stand-alone power supply in a fully automatic manner. The Sunny Backup system can be added to new and existing PV systems very easily, without impairing PV efficiency.
