The history of Fronius begins in 1945. At that time, charging car batteries was not something that could be taken for granted. Günter Fronius was unwilling to accept this. To begin with, he repaired electrical appliances and he built his first charger using 50 Hz technology. An old army hut in Rankleiten near Pettenbach, where the Fronius family lived at the time, was the first company headquarters for this “specialist repair workshop for radios and electrical engineering”. With a small workshop next to the living quarters and his first employee Andreas Schinker, Günter Fronius laid the foundations for a global company.In 1950, Günter Fronius expanded his product portfolio to include welding transformers. With technology as its focus, in the decades that followed Fronius continued to grow into a successful medium-sized company, which Günter Fronius then handed over to his children Brigitte Strauß and Klaus Fronius at the start of the eighties. Driving forward their growth and internationalisation strategy saw the establishment of subsidiaries around the world. In 1992, the decision was taken to focus on the “future field” of solar energy, which is why the company today is split into three strong divisions: Perfect Welding, Solar Energy and Perfect Charging. Join our ZERO Home Bills Community. BEST Solar Battery Products from the BEST Solar Brands at the BEST Retail Prices on by Solaranna.
