Fronius Inverters

Fronius History

Beginning with a one-man operation back in 1945, Fronius has grown to become an integral part of the solar landscape. Over the past 75 years, they have developed as a family business from a regional specialist repair shop into a player on the global stage. Their story starts with the company’s founder, Günter Fronius, who made a living as a repair and maintenance man. Then came the idea that changed everything: the trained electrical engineer built a device for recharging car batteries, allowing them to be used for longer. And with that, Fronius was born.

In 1980, Günter handed control of the company to his children, Brigitte Strauss and Klaus Fronius. The siblings started a strategy of growth and internationalisation, with numerous subsidiaries being established around the world. At the beginning of the 1990s, Brigitte and Klaus started to place an additional emphasis on the solar energy industry. Written off by some at the time as nothing more than dreamland, this sector has since established itself as an integral part of the business.

In 2001, the Fronius IG was developed and produced. This was an huge leap forward in the innovation and progression of solar inverters. For the first time, plug-in cards were used to upgrade the inverter. This gave the IG a unique future-proof feature that had been previously thought impossible. The importance placed on being able to upgrade the inverter throughout it’s lifetime demonstrates the exceptional quality and confidence in the products longevity. The Fronius IG was so successful that it wasn’t until 2015 that it was discontinued.

In 2010, Fronius opened its Australian office. The Melbourne based office has been integral to meeting the increasing demand for solar products in Australia. Here, the company not only provides customer service and technical assistance but also offers product demonstrations and training courses.

Fronius Inverters Today

One of the unique features found in Fronius inverters is the SnapINverter technology. The SnapINverter technology functions as a standardised wall mounted bracket with the inverter on a hinge system. This means servicing the inverter is much easier as the inverter opens up without the need to be remove the inverter from the wall.
