About Fronius

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, they have developed as a family business from a regional specialist repair shop into a player on the global stage.

As the technology leader, they find, develop and implement innovative methods to monitor and control energy for welding technology, photovoltaics and battery charging. Fronius forge new paths, try something difficult and succeed where others have failed in achieving what seems to be impossible. They then came up with an idea to build a device for recharging car batteries, allowing them to be used for longer.
