Fronius Inverter

Fronius, a prominent global technology enterprise, specialises in pioneering energy sector solutions. Founded in Austria in 1945 by Gunter Fronius, the company has emerged as a key player in the renewable energy industry.

Originally established as a modest welding business, Fronius swiftly diversified its product lineup to encompass battery chargers, welding transformers, and other industrial electronic devices. In the 1990s, the company transitioned its focus toward renewable energy technologies and introduced its inaugural grid-connected inverter for photovoltaic systems in 1995.

Since then, Fronius has remained committed to continuous innovation and product expansion, solidifying its status as a premier provider of solar inverters, battery storage systems, and monitoring solutions for residential, commercial, and industrial applications. The company places a strong emphasis on sustainability, earning recognition for its endeavours to diminish its environmental footprint and advocate for renewable energy.

Presently, Fronius boasts a global presence, with subsidiaries and sales partnerships spanning across more than 60 countries worldwide. Employing a workforce of over 5,000 individuals, the company maintains a robust commitment to research and development, reflected in its portfolio of over 1,000 patents and patent applications.

Notably, Fronius inverters were instrumental in the 2018 implementation of the Tokmak solar farm in Ukraine, a remarkable 51.9MW installation featuring 65 Fronius Eco 27.03-s inverters. Covering an expansive area equivalent to 130 football fields, this solar farm effectively delivers clean and sustainable energy to 80,000 people.

Our Thoughts

A quality European manufactured product, with a strong and long trading history.

The Australian office allows for warranty issues to be catered for, even if your installation company disappears.

They will be a good choice by anyone wanting a quality and premium inverter, that will last the test of time and produce power for years to come.

We would put them on our own house or business, although making sure the noise doesn’t impact our everyday living by placing the inverter well out the way.
