SMA Solar Technology AG Safety
2 Safety
2.1 Appropriate Usage
The Automatic Switch Box is a changeover facility for Sunny Backup-Systems. Sunny Backup regulates
and controls the Automatic Switch Box and acts as an island grid in case of a power outage. During
a power outage, the Automatic Switch Box safely disconnects the connected PV system and the
connected consumer loads from the public grid and connects them to the island grid.
You have the option of integrating a generator into the Sunny Backup-System providing you selected
the "Generator connection" feature when ordering the Automatic Switch Box. The generator
connection can be ordered as an option but cannot be retrofitted.
If a generator is integrated into the Sunny Backup-System, the Automatic Switch Box switches it to the
island grid if necessary.
Connection requirements
The Sunny Backup-System is only certified for TN grids and may not be installed in TT grids.
The Automatic Switch Box may only be operated in conjunction with 6, 9 or 12 Sunny Backup
(in2to4 clusters).
The Sunny Backup-Master of the Main Cluster evaluates the data recorded in the Automatic Switch
Box, coordinates all switching operations and controls all components of the Sunny Backup-System.
The maximum connection power of the individual outgoing lines in the Automatic Switch Box may not
be exceeded.
Do not use the Automatic Switch Box for purposes other than those described here. Alternative uses,
modifications, and the installation of components void the warranty claims and operation permit.
