SMA Backup Secure

The system can be equipped with the manual secure power supply function SMA Backup Secure when SMA Backup Start is installed. In the event of a power outage, the inverter can continue to supply selected loads with power from the battery and the PV modules connected to the Sunny Boy Smart Energy. The loads are connected to the inverter via a socket. SMA Backup Secure is started manually, if needed, via a switch connected to the inverter. SMA Backup Secure can be activated in case of a power outage when AC voltage is no longer being applied to the inverter. Switch and socket are not sold by SMA Solar Technology AG.

SMA Backup Secure must be combined with a rapid shutdown initiator. This can be an external rapid shutdown initiator or the DC load-break switch of the inverter, configured as a rapid shutdown initiator.
