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.
