Backup power options and products

Simply secure: basic backup power supply

Our Fronius GEN24 and GEN24 Plus inverters come as standard with PV Point, a basic backup power feature. During a power failure, energy is supplied to selected single-phase loads via a designated socket, without the need for a battery. For added convenience, PV Point Comfort continuously supplies selected electrical loads during normal grid operation and in the event of a power outage.

Maximum autonomy with Full Backup

With our Full Backup options, you can power your entire household with self-generated electricity during a grid failure as long as sufficient energy is available from the PV system or battery. A Fronius hybrid inverter and a battery, together with the Backup Switch* and Backup Controller*, ensure a smooth transition to backup power mode. Both switching components can be installed in the switch cabinet to save space.

Maximum performance including backup

A self-sufficient and secure energy supply—the Anzi family relies on a complete PV system from Fronius

“One advantage of the Fronius GEN24 Plus is the backup power function. If there’s a power failure, we can continue to use our self-generated electricity. This gives us even greater independence from the grid.”
- Ralf Anzi (homeowner)

Did you know?

Not all PV systems are automatically blackout-capable
A combination of backup power and black-start capability in the hybrid inverter and battery enables the system to reactivate itself automatically, even without power from the grid. Our Fronius GEN24 Plus and Verto Plus hybrid inverters and our Fronius Reserva high-voltage battery boast these features, making you truly self-sufficient in your home.
