Three business units One passion

Fronius displays its expertise in three business units - Perfect Welding, Solar Energy and Perfect Charging. However, each one must strive to be distinct. Take any Fronius product. Many have already been dismantled, analysed and rebuilt, but when all’s said and done, the end result is not always the same. Because performance cannot be replicated. Performance remains distinctive.
