From its roots as a simple one-man operation back in 1945, Fronius has grown to become an integral part of the industrial landscape. Over the past three quarters of a century, we have developed as a family business from a regional specialist repair shop into a player on the global stage. Our story starts with the company’s founder, Günter Fronius, who made a living as a repair and maintenance man. Then came the idea that changed everything: the trained electrical engineer built a device for recharging car batteries, allowing them to be used for longer. And with that, Fronius was born.
