Fronius Symo Hybrid The flexible hybrid inverter

Hybrid inverter for individual storage solutions

As it is so flexible, the Fronius Symo Hybrid inverter is suitable for a very wide range of applications. Such as retrofitting a storage system for existing PV systems or coupling with other energy sources. Thanks to integrated Multi Flow Technology, the Fronius Symo Hybrid enables optimum use of solar energy and maximum self-consumption for the PV system.

Maximum flexibility thanks to Multi Flow Technology

Thanks to integrated Multi Flow Technology, a wide range of applications are possible with one inverter. The inverter also enables DC or AC coupling of battery storage. Thus, already existing PV systems or other energy sources, such as wind power plants*, can be easily integrated and then form a common, efficient energy system. The Multi Flow Technology provides intelligent management of the various energy flows. This enables optimal use of produced as well as stored energy, as it facilitates parallel and simultaneous energy flows.


  • Maximum rate of self-consumption
  • High degree of self-sufficiency
  • Broad field of application

* Fronius hybrid inverters are not a replacement for wind power plant inverters. Nonetheless, the battery can be charged using energy from the wind power plant.

Simple installation and servicing

The SnapINverter technology means the inverters are safe and easy to install, intuitive to use and can be serviced quickly and easily. In addition, the Fronius Symo Hybrid inverter offers numerous open interfaces for easy connection of third-party components. For example, you can also integrate home automation products into the energy system.

  • Quick and secure installation & servicing
  • Serviceable on site
  • Easy connection of third-party components


In the event of a grid failure, the Fronius Symo Hybrid inverter provides reliable, three-phase backup power operation. Thanks to the integrated Full Backup feature, the storage system supplies the entire household with electricity during a power failure.*

  • Supplies the entire household (also three-phase loads)
  • Automatic switch to backup power in the event of a power failure
  • Efficient energy flows thanks to Multi Flow Technology also in the event of a power outage

*Only possible with BYD battery.

Our new GEN24 hybrid inverter generation is even more flexible in the case of emergency power.

Flexibility with the Symo Hybrid

“The high flexibility of the Fronius Symo Hybrid allowed us to expand the PV system with an energy-storage unit a few years after the initial installation,”

reports the May family who live in Australia. 

In 2015, the family installed a PV system with a Fronius Symo Hybrid inverter and expanded it with a BYD battery.
