Finding innovative solutions to new challenges is what motivates us, just like it always has since the company was founded. Back in 1945, Günter Fronius found the poor service life of car batteries completely unacceptable and vowed to find a new way. Nowadays, it’s the ever-inquisitive engineers in our ultra-modern R&D centre in Thalheim who are asking the right questions: How can we squeeze even more energy out of our photovoltaic systems? How can we improve the way batteries are charged? How can we create the perfect welding arc?

Of course, efficient research and development activities demand professionalism and leading-edge technology: climate chambers, grid simulators, software and hardware-in-the-loop simulations, testing labs, etc. Our staff in Thalheim has already come up with over 1,000 patents. From ground-breaking research into electro technical principles to the development of hardware and software and the manufacturing of prototypes, we have a wealth of activities that will stretch any professional who wants to put their energy to good use.
