CREDIT RATING
When Günter Fronius developed the first
battery charging system in 1945, he laid the
foundations for what the company has
represented for over 75 years: the constant
search for pioneering solutions to
the technical challenges of the times.
In developing new markets for Fronius, our
desire never changed: to be the technology
and quality leader. Today we have 34
international Fronius subsidiaries and sales
partners in more than 60 countries.
We at Fronius think in terms of sustainable
growth, not quarterly figures. We are not
motivated by share prices, but by exciting
innovations. This enhances our strength
and stability.
