Fronius Primo GEN24 Plus Hybrid Inverter Owner’s Manual

Maximum flexibility

With the Fronius GEN24 or Fronius GEN24 Plus as the core of your PV system, you will not only be starting your own energy revolution, you will also gain access to all the possibilities and advantages of solar energy. With “Fronius UP”, your PV system becomes even more flexible. A software update turns the Fronius GEN24 into our Fronius GEN24 Plus hybrid inverter

Backup power for every situation

Reliable energy supply: The Fronius GEN24 offers with “PV Point” an integrated basic backup power function. With the Fronius GEN24 Plus, you can choose “PV Point” or, with “Full Backup” *, a backup power supply for the entire household.

Built-in freedom

The Fronius GEN24 and Fronius GEN24 Plus have open interfaces. This means third-party components can be easily integrated in the system – for a customised PV system.

Easy to install

Saves time and money: Quick and reliable installation with 180° quick release screws, push-in tension clamp terminals and a well thought-out wall mounting system.

Support & tools

Endless support: Efficient Fronius solutions are available free of charge to help with planning, installation and system monitoring. This increases customer satisfaction and minimises maintenance expense.

Fronius GEN24 is available in two versions:

Inverter: Fronius GEN24
Hybrid inverter: Fronius GEN24 Plus

Impressive performance data

The Fronius GEN24 and Fronius GEN24 Plus stand out thanks to maximum efficiency and maximum output at high temperatures.
