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.

Paving the way for a future worth living

From research and development to production: Almost all of our products, solutions and digital tools are developed and produced in Europe – predominantly in Austria.

We firmly believe that the close proximity of everyone involved is also essential to the high product quality our customers know they can rely on.

We verify our high quality standards with tests under extreme conditions including extreme temperatures, humidity, ice, salt, dust and dirt, which our products and solutions withstand without sustaining damage.

The future belongs to sustainability

Sustainability has been one of our primary guiding principles since our founding. Our entire portfolio is therefore produced in the most resource-conserving way possible. This applies to how we use materials as well as to how we use energy. In addition, all our products are designed for exceptional durability and excellent repairability. This is confirmed by our life cycle analyses, which have been audited by the renowned Fraunhofer Institute for Reliability and Microintegration IZM.
