Renewable Energy Backup

Renewable Energy SMA BACKUP from 2.2kW to Set S / M / L / XL (to over 60kW for 30minutes).

Solar power – even in the event of grid failure

Greatest performance and user benefits along with the lowest investment and operating costs: in comparison with conventional emergency power systems, the Sunny Backup System scores well. As an ad-on to the PV plant the Sunny Backup automatically switches to stand-alone power supply within approximately 20 milliseconds of a grid failure. Both new and existing PV plants can be equipped with a Sunny Backup System – with no effect on PV efficiency. And the best part: due to the integration of the PV plant, a small and therefore low-cost battery can be implemented as it is usually only needed to bridge the night hours.
