Fronius solar inverters reviews

Fronius Customer Service: 03 8340 2900

Fronius is a European company established by founder Günter Fronius in Austria in 1945.

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. Fronius’s solar division has been operating in this field since 1992.

In late 2010, Fronius opened its Australian office, based in Melbourne. Here, the company 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 that they have well and truly caught up in the last 5 years. I would happily have one of these inverters on my house.

They 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 input free for a third roof area.

The only downside with the Fronius hardware that I am aware of is they 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 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 (out of pocket). Once the issue has been confirmed, the installer will then contact Fronius on your behalf. Fronius will then work with the installer to arrange for replacement of the inverter. If a customer needs help sourcing an installer, the company is able to make a recommendation.
