The SMA Sunny Backup 5kW from Critical Power Supplies


Solar power – even in the event of grid failure

Best performance, greatest user benefits and lowest investment and operating costs: in comparison with conventional emergency power systems, the Sunny Backup System scores well. As an add-on to the PV system, the Sunny Backup automatically switches to off-grid supply within approx. 20 milliseconds in the event of a grid failure. New and existing PV-plants can be equipped with the Sunny Backup – without affecting system efficiency. And the best part: due to the integration of the PV system, a small and therefore low-cost battery can be implemented as it is usually only needed to bridge the night hours.
