Our single-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 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.
