Fronius Symo GEN24

Inverters for private photovoltaic systems with backup power function

Our three-phase Fronius GEN24 inverter is the heart of private photovoltaic systems.
The Fronius GEN24 is equipped with PV Point, an integrated basic backup power function that supplies backup power to connected devices via a protected socket (as long as the sun is shining).*

The Fronius Symo GEN24 boasts a wide range of features that support a sustainable, independent energy supply. Discover the key features for installers and their customers:

/ Intelligent energy management

/ Active cooling for a longer service life

/ Flexible and fast installation

/ Easy integration and management of Fronius or third-party components thanks to open interfaces

*The Full Backup option is not available for the Fronius Symo GEN24 3.0-5.0.
