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 Fronius Energycell, which first went into development in early 2002, is one of these future-proof projects. This system has been designed to convert solar energy into hydrogen for storage. In 2009 it was certified as the first system of it's kind anywhere in the world by TUV Sud.
