A solar pioneer from day one The story of Fronius solar energy

Fronius has been engaged in the renewable energy sector - particularly solar energy - since 1992. The first Fronius inverter - the Sunrise - was developed in 1995, marking the birth of the Fronius Solar Energy division. We are the third and youngest of the three Fronius divisions. 

In 2001, the former production site in Pettenbach Austria witnessed the development and production of the Fronius IG. This was an immense and innovative leap forward in the field of inverters. For the first time, plug-in cards were used to upgrade the device - giving the Fronius IG a unique future-proof feature that had been previously thought as impossible. The product lifetime of the inverter clearly demonstrates its exceptional quality; it was not until the end of 2015 that the Fronius IG was discontinued. 

Along with manufacturing inverters, Fronius has also been consistently working on different research projects from it's earliest days - always driven by the aim of making renewable energy future-proof.

The next evolutionary leap forward for inverters came in 2013: the Fronius Galvo. The Fronius Galvo marked the arrival of the SnapINverter generation on the world market. The intelligent design of the Fronius Galvo and the SnapINverter models that followed caused delight among installers and customers alike.

Our milestones

The future in our sights

The effects of climate change are undeniable; freeing ourselves from an outdated dependence on coal and crude oil as a source of energy is becoming steadily important for both utility companies and consumers. Fronius has made significant leaps in this direction with the the Fronius Energy Package. The Fronius Energy Package not only generates energy but also stores the surplus solar energy in within the Fronius Solar Battery to be consumed as needed - even if the sun isn't shining. 

The 2015 World Climate Summit brought climate targets to the fore - targets Fronius have represented and been working towards for many years. We understand the future will hold countless challenges, from e-mobility to efficient energy management and comprehensive strategies for energy supply. At Fronius we plan to meet these challenges head on; we will continue to play a crucial role in the future and carry out research into new, revolutionary technologies. 

Our vision of 24 hours of sun



a future without reliance on fossil fuels

Over the years Fronius Solar Energy has become much more than just an inverter manufacturer. Today, our division is a pioneer in the field of renewable energy. Under the motto of “24 hours of sun”, Fronius is presenting our vision of a future without reliance on fossil fuels. This is a completely new energy strategy in which only renewable sources are used to supply the population with power - join the renewable energy revolution. Find out more
