Founded in 1945 by Günter Fronius in Pettenbach, Austria, Fronius International GmbH began as a company specializing in battery charging systems. Over the decades, it has evolved into a global technology leader, expanding into welding technology and solar energy. In 1992, it entered the solar market with the introduction of its first solar inverter, the Fronius Sunrise.

By 2022, it surpassed €1 billion in sales for the first time in its history. To meet increasing demand, the company has been investing significantly in expanding its production capacities, aiming to produce 3,000 inverters per day by the end of 2023. This expansion underscores Fronius’s commitment to delivering high-quality, efficient, and reliable inverters for residential, commercial, and industrial solar applications.
