Additional Info (Advertising)

A passion for new technologies, intensive research and revolutionary solutions have been shaping the Fronius brand since 1945. As technology leader, we find, develop and implement innovative methods to monitor and control energy for welding technology, solar energy and battery charging.

The advanced technology and sheer quality of the innovative products from Fronius have filled people with enthusiasm for generations, inspiring confidence, trust and satisfaction. Their sustainability is impressive, they boost productivity, increase energy yields and also reduce operating costs. They help our customers to make significant progress and lay the foundations for growth and successful development.

Fronius has 24 subsidiaries on four continents – yet we are still the same owner-managed company we have always been, combining the values of a family business with regional roots, with the visions of a global company.

Three divisions – best bankability

In the Perfect Welding Division, we direct our attention to generating the perfect arc to ensure consistently high welding quality. The focus for our Solar Energy and Perfect Charging Divisions is to have a reliable and comprehensive energy supply realized with renewable energy – 24 hours a day. We call this “24 hours of sun”

Solar pioneer since 1992

Our mission at Fronius Solar Energy is to drive the transformation to 100% renewables, to 24 hours of sun. We are therefore concentrating on developing solutions and solar technologies that make it possible to generate, store, distribute and consume renewable energy intelligently, efficiently and economically since 1992. With 25 years of experience in solar technologies we are solar pioneers from the very first hour.

1. Fronius Eco

The three-phase Fronius Eco in power categories 25.0 and 27.0 kW perfectly meets all the requirements of large-scale installations. Thanks to its light weight and SnapINverter mounting system, this transformerless device can be installed quickly and easily either indoors or outdoors. This inverter range is setting new standards with its IP 66 protection class. Furthermore, thanks to its integrated double fuse holders and optional overvoltage protection, string collection boxes are no longer necessary.

2. Fronius Primo

The Fronius Primo in power categories from 3.0 to 8.2 kW perfectly completes the SnapINverter generation. This single-phase, transformerless device is the ideal inverter for private households. Its innovative SuperFlex Design provides maximum flexibility in system design, while the SnapINverter mounting system makes installation and maintenance easier than ever before. The communication package included as standard, with WLAN, energy management, several interfaces and much more besides, makes the Fronius Primo a communicative inverter for owner-occupiers.

3. Fronius Symo

With power categories ranging from 3.0 to 20.0 kW, the transformerless Fronius Symo is the three-phase inverter for systems of every size. Owing to the SuperFlex Design, the Fronius Symo is the perfect answer to irregularly shaped or multi-oriented roofs. The standard interface to the internet via WLAN or Ethernet and the ease of integration of third-party components make the Fronius Symo one of the most communicative inverters on the market. Furthermore, the meter interface permits dynamic feed-in management and a clear visualisation of the consumption overview.
