The history of the division - solar energy

Fronius has been engaged in the field of renewable energy, particularly solar energy, since 1992. The first Fronius inverter, the “Sunrise”, was developed in 1995. This marked the birth of the Fronius Solar Energy division. The youngest of the three Fronius divisions was responsible for a revolution in 2001, when on the roof of Fronius' former production site in Pettenbach, the Fronius IG inverter was energized for the first time. The Fronius IG was an immense leap forward in the field of inverters because for the first time plug-in cards could be used to upgrade a device. The WLAN module was developed to provide additional network options; a future-proof feature that had never before been deemed possible. 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.

As well as manufacturing inverters, Fronius has been consistently working on different research projects, always with the aim of making renewable energy future-proof. The Fronius Energycell, which first went into development as early as 2002, has been designed to convert solar energy into hydrogen and store it. In 2009 it was certified as the first system of its kind anywhere in the world by TÜV Süd.

The next evolutionary leap forward for inverters came in 2013: the Fronius Galvo marked the arrival of the SnapINverter generation on the market. The intelligent design of the Fronius Galvo and the models that followed were warmly received by installers and customers alike.

Our milestones

The future in our sights

Freeing ourselves of our dependence on coal and crude oil is becoming an increasingly important matter – not only for utility companies, but also for each and every consumer. Fronius has made a significant step in this direction with the launch of its Fronius Energy Package, with which surplus solar energy is stored in a battery and consumed as needed – even if the sun isn’t shining. The World Climate Summit 2015 brought climate targets to the fore, which Fronius has represented and been working towards for years. The future holds countless challenges, from e-mobility to efficient energy management and comprehensive strategies for energy supply. Fronius will continue to play a crucial role in the future and carry out research into new, revolutionary technologies.
