ABOUT US
Fronius Sattledt

Our history

One of the earliest solar pioneers

The history of Fronius’ youngest business unit dates back to 1992 when Fronius Solar Energy was founded. A lot has happened in the meantime. 

One of the first key milestones was the first Fronius inverter, the Fronius Sunrise. Since then, we have significantly expanded and developed our product range.

At the same time, we are working on many research projects, particularly in regard to hydrogen. Countless awards in a wide range of categories are testament to our success and many years of experience.
All our experience and each and every project bring us ever closer to achieving our vision of 24 hours of sun.

Focus on our roots – then and now

The Fronius story begins all the way back in the 1940s. At that time Günter Fronius founded a simple one-man business in Pettenbach. 

Now we are a strong global player and one of the most prominent names in the industry. As a stable family business, we are very proud of our regional roots and are still strongly connected to them to this day. From Upper Austria, Fronius Solar Energy is now represented by more than 20 branches around the world.

Sustainability as a driving force

Sustainability has played an important role for us since day one. For example, over 75 years ago, company founder Günter Fronius was looking for a solution for charging batteries so that they could be used for longer. This marked the day on which the Business Unit Perfect Charging was founded and since then we have lived and breathed sustainability and it is firmly rooted in our DNA.
