Fronius International

For over 60 years the name Fronius has stood for intensive research and the constant search for new, innovative solutions. The perfect efficiency of every product has repeatedly been awarded both national and international prizes.

Solar Electronics

We have been closely involved with solar electronics since 1992. Our aim is to revolutionise the energy supply of our planet to achieve energy self-sufficiency. 
The highest possible level of quality is at the forefront of all our activities. This is demonstrated not only by our powerful, grid-connected inverters, but also by our comprehensive range of system monitoring products.

However, energy self-sufficiency requires more than temporarily available photovoltaic electricity, which is why Fronius has already spent many years researching into efficient ways of storing solar power. Our development of the Fronius Energy Cell represents a milestone for this sector. The objective is to store excess PV current in the form of hydrogen and to release it again as electricity when required.

The high quality of Fronius is not only apparent from our products: our technical support and unmatched Fronius Service Partner Programme are unique selling points and an important part of our philosophy.

Whenever it starts to develop a new product, Fronius critically examines the prevailing technology on the market and comes up with innovative ideas and new solutions. Solutions that we use in Solar Electronics every day in shifting the limits.


Grid-connected inverters

Solar energy is converted into electricity and fed into the public grid. Efficient, reliable, high power inverters form the heart of any PV system. In the development of PV inverters, Fronius has thought out new technologies, searched for innovative solutions, and has found completely new answers. The result: Highly functional mains-connected inverters, which interact optimally with all solar modules.

System Monitoring

Fronius DATCOM is a user-friendly data communications system for individual PV system monitoring. The hardware components are quick and easy to install, the software easy to operate. Because of its modular design, Fronius DATCOM can be upgraded at any time. Customized monitoring solutions, from basic equipment to complete system management, can be installed quickly and without problem. Because every PV system operator wants to know how their investment in the system is doing.

The Fronius Energy Cell

Ensuring a year-round autonomous energy supply involving photovoltaics was previously only possible by having environmentally-damaging diesel generators to fall back on. Fronius has found a new solution – the Fronius Energy Cell. In future, the energy cell can be used to convert excess energy into hydrogen for storage, converting it back into useful power when needed.
