Fronius Solar Inverters Review

Fronius solar inverters


If you’re thinking about investing in solar for your home, choosing the type of inverter for your PV system is one of the most important decisions you’ll make.

To help you make a well-informed decision, Solar Market has written a series of blogs reviewing four of the most commonly sold solar inverters in Australia, including Fronius, Sungrow, Enphase and SMA.

In order to give a balanced review, we’ve taken into account several criteria including company background, sustainability practices, product range, warranties, and pricing.

To find what we rated Fronius inverters, read on.

About Fronius

With its origins in battery chargers and welding transformers extending back to 1945, and their first inverter manufactured in 1995, Fronius is one of the oldest and most respected inverter manufacturers in the world.

Headquartered in Austria, and with nearly 4,000 employees working across 24 countries around the world (in addition to representatives in over 90 countries), Fronius inverters are also one of the only brands compatible with Tesla Powerwall. Fronius opened its Australian office in Melbourne in 2010, where it facilitates all warranty and service requirements.

All Fronius inverters and associated products (including solar batteries) are manufactured in Austria.

Environmental Commitment

Fronius’ core values of community, profitability, innovation, sustainability and quality consciousness lie at the heart of the organisation’s business model, fuelling a corporate-wide respect for the environment, economy and society.

Following an external audit, Fronius achieved ISO14001 certification for its environmental management system in 2014.

With more than 70 years of experience in the manufacturing industry (more than 20 of which involve manufacturing solar inverters), several awards, a solid commitment to sustainability, and rock-solid reputation for quality and reliability, purchasing a Fronius inverter is a very safe bet.

We’re awarding their products a 4-star rating and would be happy to install Fronius products in our own homes, as well as recommend them to family and friends.

(We’re knocking off a star due to the fact their warranty does not cover removal, installation, labour or transport costs in the very rare occurrence of a fault, unlike other manufacturers including SMA and SolarEdge.)
