Fronius Primo GEN24 Plus

The hybrid all-rounder with individual back-up power

With need-based emergency power variants, which can operate with or without a battery, the Fronius Primo GEN24 Plus delivers the highest degree of supply reliability for the home sector.

The innovative PV Point provides for the first time a basic emergency power supply even for those customers who do not wish to purchase a battery straight away. For customers who already have a battery, the device offers a tried-and-tested full backup solution that can supply the entire household with emergency power. 

The Fronius GEN24 Plus devices are therefore the ideal solution for a whole range of customer requirements; whether the system is to have a battery from day one, a Fronius Ohmpilot is to use PV energy to heat the hot water, or the PV system is to be integrated into a home automation package. Fronius GEN24 Plus will always be the right choice – for new systems as well as the upgrade and expansion of existing solar systems.

Furthermore, the new devices make installation, commissioning and servicing incredibly easy and can be used in every type of system. Proven Fronius technologies, such as the SuperFlex Design, will also be found in the Primo and Symo GEN24 Plus – devices that offer ideal storage solutions for single-phase and large three-phase systems.
