Fronius Solar Inverters

A passion for new technologies, intensive research and revolutionary solutions have been shaping the Fronius brand since 1945. As the technology leader, we find, develop and implement innovative methods to monitor and control energy for welding technology, photovoltaics and battery charging. We forge new paths, try something difficult and succeed where others have failed in achieving what seems to be impossible. But these are not the only reasons why Fronius is the global leader in innovation and technology. We have a clear vision, an unremittingly inventive spirit and an ingrained sense of quality, so we can keep shifting the limits of what is possible and set the trends that change the market. In the Perfect Welding Business Unit, we direct our attention to generating the perfect arc to ensure consistently high welding quality. The focus for our Solar Energy and Perfect Charging Business Units is to have a reliable and comprehensive supply of energy – 24 hours a day.

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 34 subsidiaries on five 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.

Why Fronius?

Fronius products and solutions taking us a step closer to 24 hours of sun. 

At Fronius, responsible business practice means taking into consideration environmentally-relevant, social, and economic factors in equal measure. We always endeavor to optimize processes and utilize synergies in the production process. We keep energy and raw material requirements as low as possible, for example through the use of fuel-efficient machinery, energy recovery, minimizing sheet metal waste, or by using reusable packaging. Robust components and high production quality promise a long service life.

Impact test, dust test, low temperature performance – these are just three of the 13 quality tests that our products undergo during the development phase, depending on the intended area of application of course. All our tests go far beyond the specifications laid down in standards: it is no coincidence that innovative solutions from Fronius impress with their quality and long service life. And if required, the products can be easily repaired and individual components replaced.

Low-emission heating systems are used at all our Austrian sites. In fact, at the research and development site in Thalheim, we cover 100% of the heating requirements using a Co2-neutral geothermal field. The geothermal system situated here is one of the largest in Europe, with 204 boreholes of 200 meters each. What’s more, we use the heat from the test laboratory for heating in winter and the river water from the nearby Traun for cooling in summer.

The sun provides most of the energy that we need. We use special photovoltaic systems, some of which are installed directly in the facades, and some of which are integrated in the covered parking lot roof. One of the largest roof-mounted PV systems is situated at our production site in Sattledt and has a module surface area of approximately 7000 m². The system delivers more than 1000 kWp of electricity, equating to the energy requirements of roughly 250 households.

Solar Power Inverters

Fronius inverters are ready for the Smart Grid of tomorrow. The inverters are optimally equipped to meet the technical requirements of grids in the future. A series of smart functions, known as Advanced Grid Features, are built into the devices. They include a number of control functions for optimum feed-in of reactive power and effective power. These functions are designed to enable stable grid operation even when the PV system density is very high and to prevent unwanted interruptions to feed-in and associated yield losses if grid parameters exceed the thresholds. Fronius inverters therefore help to guarantee the yield of a PV system. Furthermore, where feed-in limits are imposed, Fronius inverters can provide dynamic feed-in control with self-consumption taken into account. Just connect the meter and set the feed-in limit!
