Inverter with backup power function for private households

Ready for the private energy revolution: With our Fronius GEN24* inverter at the heart of their private photovoltaic system, households can produce their own energy sustainably and inexpensively.

While the Fronius GEN24 offers an integrated basic backup power supply in the form of the PV Point, the Fronius GEN24 Plus** can also provide a comprehensive Full Backup power supply via a connected battery storage system.

The inverter with flexible backup power options

Backup power for every situation

Your energy supply must be reliable. That’s why the Fronius GEN24 offers an integrated basic backup power supply. Backup power is supplied to connected devices up to 3 kW via the PV Point socket, as long as the sun is shining.

With the PV Point and Full Backup*, the Fronius GEN24 Plus offers two backup power options: a power supply for loads of up to 3 kW via a single socket and a backup power supply for the entire home, including large, three-phase loads such as heat pumps.

* The Full Backup option is not available for the Fronius Symo GEN24 3.0–5.0 Plus. For Full Backup, a battery and a switching device for safe grid disconnection are required in addition to the inverter.

 

Versatility as standard

Thanks to their energy management functions, our inverters continuously save time and money. The smart device design combined with our intelligent software enables fast and flexible installation and delivers optimum yields, even when the PV modules are in the shade. What’s more, the integrated active cooling extends the service life of the inverters, securing your customers’ investment.

 

Built-in freedom

The Fronius GEN24 and Fronius GEN24 Plus have been designed so that you can create an independent energy supply for your customers that’s as individual as possible. That’s why the hybrid inverter has open interfaces. This makes it exceptionally easy to integrate and manage components from Fronius or third-party providers.
