Fronius rezerves kontrolieris 3P-35A

The Fronius Backup Controller is a switching device that enables an automatic transition to Full

Backup mode. In the event of a power failure, it automatically switches to backup power mode and

back to parallel grid operation as soon as the grid is available again. This solution ensures that the

entire household is always reliably supplied as long as enough power from the PV system or the

storage is available - even when nobody is at home.

- Automatic solution for maximum security

- Ensures power supply to critical devices even when absent

- Quick and easy installation on a top-hat rail in the switch cabinet

- Automatic return to normal operation

The Fronius Backup Controller and Fronius Backup Switch can be installed easily, quickly and in a

space-saving manner in the control cabinet. This minimizes installation effort and costs. Additional

switch boxes with high space and cost requirements are no longer necessary.
