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 perfect heart for private photovoltaic systems. The Fronius GEN24 Plus with its PV Point provides an integrated basic backup power supply or even a comprehensive backup power solution with the option to connect a battery system.

The Fronius GEN24 Plus hybrid inverter enables energy self-sufficiency for electricity, heating, cooling and e-mobility with the use of a battery system. This means that the Fronius GEN24 Plus with Full Backup has a backup power solution that can even supply 3-phase loads, such as heat pumps. What’s more, the Multi Flow Technology lets the hybrid inverter supply parallel energy flows in the system, even in backup power mode.*

*The Full Backup option is not available for the Fronius Symo GEN24 Plus 3.0-5.0. Additional external components for grid switchover are required for the Full Backup. More information on this can be found in the operating instructions.
