2.1 Appropriate Usage
The Automatic Switch Box is a component of a Sunny Backup system M. In case of a grid failure, the
Automatic Switch Box will disconnect the PV system and the loads from the public grid and connect
them to the Sunny Backup. The optional generator is also integrated into the stand-alone grid in the
Automatic Switch Box in case of a grid failure.
Connection requirements
The Sunny Backup system is only certified for TN grids and may not be installed in TT grids.
Principle of an Automatic Switch Box in a Sunny Backup System
The Automatic Switch Box may only be operated in combination with a Sunny Backup. The Sunny
Backup evaluates the data collected by the Automatic Switch Box and coordinates all switching
operations.
The maximum connection power of the individual outgoing lines (e.g. maximum AC PV power to be
connected: 5.7 kW) 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, as well as installing components not recommended or sold by SMA may void the
warranty and any applicable interconnection agreements.
