About Fronius, Solar Inverters

Fronius solar inverters review

Fronius Customer Service: 03 8340 2900

Fronius is a European company that was established by founder Günter Fronius in Austria in 1945. Mr. Fronius kicked off with a repair shop for radios and electrical equipment and soon started making battery chargers, then welding transformers.

The company grew over time from being a welding and battery charger manufacturer to become one of the most prominent European players in the solar market. Its solar division has been operating in this field since 1992, so they have decades of experience - and this shows in Fronius inverter products.

In late 2010, Fronius opened its Australian office based in Melbourne where it not only provides customer service and technical assistance, but also offers product demonstrations and training courses.

Fronius make some of the best inverters in the world. They used to be playing catch up with SMA in terms of industry reputation and quality, but I would argue they have well and truly caught up in recent years. I would happily have one of these inverters on my house.

The inverters are easy to 'export limit', if your local network insists on this as part of your solar connection agreement. But you do have to buy the 'Fronius Smart Meter (FSM)' accessory to do this (about $500 extra). The FSM also allows full consumption monitoring (over and above solar monitoring) although I am not a fan of the Fronius SolarWeb monitoring software.

Personally, I prefer Solar Analytics and always recommend adding Solar Analytics to your Fronius inverter and using that for monitoring instead.

Fronius solar inverters usually come with 2 solar inputs (or MPPTs). Their MPPT efficiency is legendary. And if you have a symmetrical east/west facing roof you can often put both the east and the west array into one input - leaving the second inverter input free for a third roof area.

The only downside with the Fronius hardware that I am aware of is their inverters are fan cooled and can be rather noisy. Keep them away from living areas!

Fronius Solar Inverter Warranty Notes

All Fronius string inverters are accompanied by 5 years Fronius Warranty Plus. However, by registering at www.solarweb.com, customers can receive an additional 5 years warranty free of charge.

If you should experience what you believe to be a warranty related issue with your Fronius inverter, you should first contact the original installer of the unit. However, if that installer is no longer around, don't panic.

Fronius advise that in this situation they first require the customer to find an qualified solar installer to verify the issue with the inverter - but this needs to be paid for my the customer. Once the issue has been confirmed, the installer will then contact the company on your behalf. Fronius will then work with the installer to arrange for replacement of the inverter. If a customer needs help in finding an installer, the company is able to make a recommendation.

3 weeks in, all going well.
Update at almost 12 months: still going well. During the height of summer there were a few stoppages due to excess voltage, but they generally only went for a few minutes.

It's going well. It pumps out electricity at its max capacity (6kw/h) for about the middle 4 hours of fine summer days, and gets close to 4.75 kw/h for the equivalent time and conditions in winter.

When exporting power the inverter does emits a small amount of noise but as the inverter is mounted high in my garage and only makes sound during sunlight hours it’s out of the way and far away therefore rarely noticed.

It is a tad noisier than I was anticipating, though the previous Fronius I had was only 3 kW and this one is 15 kW. Lucky it is in the garage.

As the Inverter needed to mounted out of direct sun, locating the inverter under the house but near the electric switch board worked well.

After nearly 12 months of operation from installation, the Inverter has worked flawlessly. Very happy with a trusted brand and model.
