About us

30 years of fronius solar energy

We are Fronius Solar Energy. For 30 years, we have been developing innovative products, solutions and digital tools to cost-effectively and intelligently generate, store, distribute and consume solar energy.

Today our name stands for innovations that sustainably enrich the lives of private consumers as well as the businesses of our commercial customers with solar energy – true to our motto “Energize your life”. 

Living with stability and future-readiness

We are an important part of Fronius, a stable family business now in its third generation and led by Elisabeth Engelbrechtsmüller-Strauß. The essential corporate values that were prized by her grandfather Günter Fronius are still practiced today and are passed on from one generation to the next.

With our three pillars of battery charging technology, welding technology and solar energy, Fronius is solid, broad-based and fit for the future.

24 hours of sun for everyone

With our products and solutions, we make it possible to use the sun 24 hours a day. Whether for electricity, heating, cooling or electric mobility – and regardless of the time of day or season. We are thus paving the way to a livable future, where renewable energies cover 100% of the world’s energy needs.
