Fronius, founded in 1945, is a leading Austrian manufacturer of electronics with a strong presence in Australia. As a major supplier of solar inverters, its products have become associated throughout the industry with innovation and long lasting quality.

Fronius is one of the inverter brands that Proven Energy sells and installs, offering both inverters and batteries to convert and store power. Fronius inverters range in capability from 1.5 to 27.0 kW. 

The role of an inverter is to convert direct current (DC) power produced by solar panels into alternating current (AC) suitable for use in your home or business. Battery storage allows homeowners to store the energy produced during the day and use it during the night when solar isn’t available. 


Fronius Rigorously Tests Its Products

Fronius is continually innovating, and does rigorous testing on its products in all types of conditions. This testing includes extreme temperatures, moisture, ice, salt, dust and dirt, to ensure the product stands up to any condition. 


Because of this testing, Proven Energy proudly recommends Fronius products, using them across a large sector of our installations.  


Fronius also offers smart metering, which includes a user dashboard for both consumers and installers, so property owners can be alerted to any major issues within their systems via live updates.   

Our customer’s systems are monitored via our email system and alerts are also sent to each customer’s own email. Not every company offers hands on monitoring but we believe it is in our customer’s best interest and our own, that any issue that may arise is seen and dealt with as soon as possible.  

This monitoring covers things as simple as your internet provider changing and no longer connecting to your inverter, through to alerts around lack of production. This information allows us to troubleshoot and identify problems before they have a big impact on your power bill. 


Proven Energy designed and installed a solar solution tailored to my home's energy needs and budget. In the 12 months since my solar was installed, my electricity bill has been wiped out and now I receive regular cheques for surplus electricity fed back into the grid. My whole system will have paid for itself in less than 3 years.

Friendly, professional, explained options, stuck to quoted price, came back to property to check one room, found problem, fixed it at no charge. Problem was not something this electrician caused but rather a problem caused by a former home DIYer.
