Fronius Inverters

About Fronius

Founded in Austria in 1945, Fronius is recognised as one of the best solar inverter manufacturers in the world. Represented in over 60 countries, Fronius has over 4,500 employees who work in three divisions: solar energy, battery charging and welding.

Fronius originally started as a manufacturer of welding and battery charging equipment more than 70 years ago. The company’s experience in high performance welding inverters proved to be the ideal launchpad for moving into the design and manufacture of solar inverters. The company launched its first solar inverter in 1994.

All Fronius solar inverters are engineered, designed and manufactured in Austria. They are widely regarded as the highest quality string solar inverter on the market. Their efficiency and high levels of performance – even in extreme heat – make them ideally suited to the Australian climate.

In 2010, Fronius opened its Australian office, in Melbourne, where it provides customer service and technical assistance for its solar products.

Fronius inverters are amongst the most popular inverter brands in Australia due to their reliability, quality and the outstanding customer service provided by Fronius Australia. Industry authority Clean Energy Reviews, rated Fronius inverters as the number one solar inverter in Australia in 2021 for both residential and commercial installations up to 30kW.

About Fronius Inverters

With power categories from 1.5 to 27 kW, Fronius solar inverters are suitable for virtually any size solar installation – both residential and large-scale commercial – and are smart grid ready.

Perform effectively, even in extreme heat

With fan-forced active-cooling system, Fronius inverters work efficiently on hot sunny days without noticeable loss in performance, even in temperatures up to 55 degrees Celcius.

High efficiency

Residential inverter efficiency standards are generally 95 to 98 percent. Fronius inverters are rated at 98 percent efficiency or higher (depending on the model), placing them at the forefront of the industry in residential inverter efficiency.

Quick and easy installation

The unique ‘snap-in’ design of Fronius inverters means they are fast to install and service.

User-friendly online monitoring

With the free Fronius Solar.web monitoring tool, you can keep an eye on your solar production and consumption at all times. This is a huge advantage of the Fronius inverter as most other inverter brands only provide monitoring of solar production.

Neat installation

Fronius installations look neat and tidy as the DC isolator and string fusing is built into each Fronius inverter.

Excellent support

Trained Fronius Service Partners are able to carry out repairs at your premises without having to replace the device right away.

Easy to ‘export limit’

If your local network distributor insists on limiting the amount of electricity your solar power system can export to the grid, the Fronius inverter can be set up to limit your solar exports to meet the requirements of your solar connection agreement. (Note, this requires the addition of a Fronius Smart Meter).

Easy to integrate with home automation devices

The open interfaces on Fronius inverters facilitate straightforward integration into home automation systems. This means electrical devices can be switched on and off from a tablet or a smartphone according to the time, weather, etc.

Extremely low recorded failure rate.

If a failure occurs, Fronius usually ship replacement units in 3-5 business days.
