SMA Backup Secure

The manual secure power supply operation SMA Backup Secure ensures that, when needed, for example in case of a power outage, the inverter can continue to supply electric current to selected loads via the inverter. The loads are connected via a socket to the inverter and can be supplied with electric current from the battery or the PV system. SMA Backup Secure is started manually, if needed, via a switch connected to the inverter.

SMA Backup Secure can only be used if SMA Backup Start is installed in the inverter. SMA Backup Start is equipped with a battery that can be charged to start the system as soon as energy is present in the PV system or the system battery.
