Fronius Backup Controller

The Fronius Backup Controller is a switching unit that enables automatic transition to Full Backup mode. In the event of a power failure, it automatically switches to backup power operation and back to parallel grid operation as soon as the grid is available again. This solution ensures that the entire household is always supplied with electricity as long as there is enough power available from the PV system or storage - even when nobody is at home.

As a space-saving solution, the Fronius Backup Controller can be installed quickly and easily on a top-hat rail in the control cabinet. This minimizes installation effort and costs, as an additional switchover box is no longer required.

- Automatic solution for maximum security
- Supplies the entire household even when absent
- Automatic return to normal operation
- Easy and space-saving installation in the control cabinet
