Family business with tradition: Fronius celebrates its seventy-fifth birthday
Pettenbach/Wels, 06/25/2020 – What began in 1945 as a one-man business based on a simple idea is now part of the industrial landscape: we’re talking about the Austrian family-owned company Fronius, which has grown over the past three quarters of a century from a regional repair shop to a global player in the fields of welding technology, photovoltaics, and battery charging technology. And it all started exactly 75 years ago on June 20.
Günter Fronius set the ball rolling in 1945 when he started a radio and electrical repair workshop, beginning a story of success that continues to this under the stewardship of the third generation of the founding family. The business was born in the market town of Pettenbach, Upper Austria, where Fronius’s headquarters are still located. This is where Günter Fronius lived and worked after being given an old military barracks in exchange for carrying out some repair work. In those days, charging vehicle batteries was not a simple matter – something which he felt ought to change. A trained electrical engineer, he developed a solution which meant that batteries could be used for longer. “So what we are and what we stand for is based on a sustainable idea that my grandfather had,” says Fronius CEO Elisabeth Engelbrechtsmüller-Strauß, who has been managing the family business since 2012.
The welding revolution, globalization, and solar power
In 1950, Günter Fronius expanded the company’s product range to include welding transformers. Building on this technological basis, over the following decades Fronius grew into a substantial medium-sized company, which the electrical engineer handed over to his children, Brigitte Strauss and Klaus Fronius, in 1980. They launched a program of growth and international expansion that led to the founding of subsidiaries all over the world. In 1992, it was also decided to focus on solar energy as a “technology of the future”. And so, today, Fronius stands on three pillars: welding technology, photovoltaics, and battery charging technology.
Business Unit Perfect Charging
The Business Unit Perfect Charging is as old as the firm itself. Company founder Günter Fronius started charging lead accumulator batteries in the early years of the business. After numerous further developments, in the early 1990s the company switched from 50 Hz chargers to high-frequency technology for the first time. Further research lead to a real milestone in 2007 – the Ri charging process which charges the battery according to its effective inner resistance. Since then, Fronius products have automatically adapted themselves to the batteries being charged and their properties, making every charge unique. Perfect Charging is currently taking the next step into the future with lithium-ion technology, incorporating new ideas about digitalization and device networking
