    Fronius now operates on five continents worldwide with its 37 subsidiaries, although the main concentration of locations is still in Europe. In addition, the sales and service partners are represented in over 60 countries on all continents, so that optimum support can be guaranteed around the globe. 
  • What products does Fronius specialize in?
    Fronius specializes within the photovoltaic industry in the production of inverters and electricity meters. 
  • When was Fronius founded and what are they known for?
    In 1945, the Fronius company was founded by Günter Fronius, a trained electrical engineer, in Pettenbach, Austria, as a one-man operation for radio and electrical maintenance work. Fronius' fame continued to grow through the invention of simple battery chargers, and welding transformers have been part of the company's portfolio since 1950. Over the years, the company continued to expand, entering the solar business in the 1990s. Now run by the 3rd generation of the Fronius family, the headquarters are still in Pettenbach, Austria, whose mainstays today are solar energy, welding and battery charging technology.
