Fronius Symo GEN24 Plus

Inverter for private PV systems with PV Point or Full Backup

Our three-phase Fronius GEN24 Plus hybrid inverter is the ideal core for private PV systems. The Fronius GEN24 Plus offers an integrated basic backup power supply with PV Point and even a full backup power solution through the option of connecting a battery storage system.
The Fronius GEN24 Plus hybrid inverter uses a battery storage system to enable self-sufficient energy production for electricity, heating, cooling and e-mobility. Fronius GEN24 Plus with Full Backup* also has a backup power solution that can supply even three-phase consumers – such as heat pumps. Thanks to Multi Flow Technology, the hybrid inverter can even handle parallel energy flows in the system in backup power mode.
* Available on the Fronius Primo GEN24 Plus 3-6 kW as well as the Fronius Symo GEN24 Plus 6-10 kW.
