A backup power supply to meet your requirements

Supply always guaranteed

Power failures often happen when you least expect them. You may be cooking, browsing the internet or watching your favorite movie and, in an instant, the power is gone. In these moments, our backup power-capable inverters offer you a reliable PV backup power supply, making sure the lights stay on even if there is a power failure. Find out how it works and what is possible with the extensive backup power range from Fronius.

Backup power solutions for all requirements

Fronius offers the right backup power solution for everyone. From a cost-effective, basic backup power supply to Full Backup solutions that ensure maximum security, manually or automatically, with or without a battery – we meet every possible need. And the best thing is: There is no need to decide immediately which type of energy self-sufficiency is right for you. As a basic backup power supply, the PV Point is integrated as standard into all Fronius GEN24 and GEN24 Plus inverters. With the Fronius GEN24 Plus hybrid inverter combined with a battery storage system and a switching component, you can retrofit the Full Backup option at any time and keep the entire household supplied.

Simply secure: Basic Backup Power Supply with the PV Point

With the PV Point, the Fronius GEN24 and GEN24 Plus inverters offer an integrated basic backup power supply. During a power failure, energy is supplied to selected single-phase loads via a fused socket or a fused circuit. For even greater convenience, the PV Point Comfort ensures that selected electrical appliances are continuously supplied with power both in parallel grid operation and during a power failure.

Maximum independence with Full Backup

With our Full Backup variants, you can supply your entire household with self-generated electricity during a grid failure (as long as enough power from the PV system or the storage is available). The Fronius GEN24 Plus hybrid inverter and an energy storage device, together with the Backup Switch* and Backup Controller*, ensure a smooth transition to backup power mode. Both components can be installed in the switch cabinet to save space. The Fronius Backup Switch is an inexpensive 3-way switch enabling manual activation, while the Backup Controller automatically switches to Full Backup mode and returns to normal operation as soon as the grid becomes available again. The Backup Controller makes additional switchover boxes unnecessary.

Maximum performance including backup

"One advantage of the Fronius GEN24 Plus is the emergency power function. If there is a power failure, we can continue to use our electricity from the roof. We have created further independence here."
