Finn's Fronius Inverters Review & Verdict

Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO

Fronius inverters are brilliant: reliable, high performance with a very smart optimisation algorithm to squeeze lots of energy from panels even with partial shade or on multiple roof areas.

But beware: a Fronius-powered solar system is only as good as the designer designing it and the installer installing it!

Make sure you buy the Fronius GEN24 - it is better and quieter than its 'SnapINverter' predecessor. And if you choose to upgrade to batteries later, the inverter can be software-upgraded to control batteries at any time for $650 to $1000 depending on the inverter size.

Fronius Inverters: Pros & Cons

  • Brilliant local support and warranty.
  • Ethical approach to full life cycle, packaging, repairability and recycling.
  • Thoughtful connection area makes it easy to install in a very neat and compliant manner.
  • High DC input current for modern panels and flexible parallel arrays.
  • Great surge capacity for hybrid output during a blackout.
  • Open source compatibility for smart control of other loads.
  • Compatible with the excellent Wattpilot EV charger.
  • 40-second delay on hybrid backup is an unmissable indication you need to conserve energy.
  • The fan means it stays cooler, lasts longer and yields more energy.
  • The fan makes some noise, but new models are very quiet.
  • 40-second delay on hybrid inverter backup means you'll need to reset the clock on the oven.
  • Premium price (but you get what you pay for)
  • 53Hz output during a blackout means hybrids don't play well with some appliances or any other solar inverter.
  • Old and new Fronius show up on the same Solarweb portal but they do not talk to each other or coordinate output. There can only be one Gen24 running in a power outage.
  • The well-loved SnapINverter series is being phased out.

About Fronius

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 hardware market. Its solar division has been operating since 1992, so they have decades of experience - and this shows in Fronius inverter products.

In late 2010, Fronius opened its Australian office 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 once were playing catchup with SMA in terms of industry reputation and quality, but I would argue they have well and truly done so in more recent years. I would happily have one of these inverters on my house and Fronius is currently a SolarQuotes recommended inverter brand

In the 2024 SQ Installers' Choice Awards, Fronius achieved the top spot for the fourth year in a row - and quite convincingly. It was also voted by installers as offering the best after-sales support.

Fronius inverters are easy to 'export limit'. But you do have to buy the 'Fronius Smart Meter (FSM)' accessory to do this. The hardware costs around $250 for a single phase system and installation can cost up to a couple of hundred bucks..

The FSM also allows full consumption monitoring (over and above standard 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 - using that for monitoring instead (or in addition to).

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 tech-related downside with the Fronius hardware I am aware of is in relation to their inverters being fan cooled. While this improves efficiency and longevity, it can be rather noisy in the older SnapINverter models; particularly on hot days. Keep them away from living areas! The noise isn't such an issue with the GEN24 models. 

You'll also pay more for a Fronius inverter than many other brands; but that extra cash is money well-spent given the quality and bearing in mind an inverter is the true workhorse of a solar power system. 

Fronius Solar Inverters Available In Australia

The product lines available in Australia for some years were the Fronius Primo (single phase) and Symo (three-phase). These have proven their mettle in Australia's often harsh conditions.

More recent additions are the Primo and Symo Gen 24 Plus. These are hybrid inverters designed for use in conjunction with batteries. However, a really interesting feature is PV Point, which enables backup power without a battery supplied to a dedicated power point installed near the battery or inside the home. Assuming sufficient solar power resources are available, it can provide a maximum 3kW during a blackout situation - but watch out for clouds!

There's also a non-hybrid Primo Gen 24 available - which doesn't have the PV Point feature. 

Various specifications and estimated pricing for Fronius gear can be found on our solar inverter and hybrid inverter comparison tables.

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. But note that while the first 5 years covers parts and warranty, the second only covers parts.

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. But 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.

The Fronius Symo 5.0-3-M seems to be an excellent inverter, although their web connectivity is quite backwards, with the web interface looking like it was stuck in the early 2000's. I've had to factory reset this inverter several times, and eventually used ethernet as the WiFi module wouldn't work on a 5GHz network.

In the future I'd likely look at purchasing a less expensive inverter as I felt that the Fronius Symo 5.0-3-M does not represent value for money.

We decided to add the Fronius Smart Meter to the Fronius Inverter and are very happy with all the information that it is providing to us. We needed to speak with technical support after the installation and called the Sydney office. Support assistance was extremely helpful and patient, and solved all the issues we had.
12 months later .. The Fronius Inverter is super efficient and has performed even higher than the averages. The Smart Meter provides all the information you need to monitor the system and your production, and we use it all the time .. also very easy to use.

We have two and I lovingly call them the Fronius Twins. In the first few months of having them installed I would check on them twice a day to make sure that the correct lights were lit. It is not a necessary thing to do. It was me just being paranoid with my new purchase not unlike buying a new car and checking that no-one has scratched it when you have been to the shops. They did keep dropping out of our internet from time to time so we purchased a booster (not expensive) and have not had that issue since. Dropping off your internet only means that it doesn't transmit your solar information to the base so you cannot see what you are Making/Using and sending back to the Grid. It's a handy tool that causes you to Rub your hands together with Glee and look forward to that Electricity Bill when it arrives. I could not be happier with our Fronius Twins purchase and the way in which they perform.

The Fronius Gen24 is situated in the laundry on a wall behind the meter box. At full capacity the fan is fairly quite and even with the laundry door open cant really be heard in any other rooms.

We like the simple display of just two lights which you can tell at a glance if operating properly or not.

The PV point could be a useful feature during a prolonged blackout to power the fridge or freezer (providing PV is generating)

The Fronius Primo GEN24 6.0-1 inverter works seamlessly with the Fronius smart meter, switching to battery backup when mains power goes out - as it does frequently in Far North Queensland. Power is cut for about 30 seconds and then resumes from the battery. I have highly rated energy-saving appliances so I asked for all power circuits to be available on backup. I am careful to monitor how much current I am drawing and this has never been a problem. Some reviews mention the noise of the inverter fan but in my experience, it is hardly noticeable from close up in the garage and not at all in the house.

Fronius is one of the oldest, if not oldest inverters available on the market. Their longegivity and positive reviews all around provides positive insights of the company. It is regarded as one of the top brands of inverters availabe on the market. The availibility of metrics from the system (power produced, power consumption and power feeding back into the grid) may provide further insight on the benefits of your investment, and possibly happiness in my personal experience.

The Fronius Symo inverter worked great. Only downside is that even though it is a 3 phase inverter, it only seems to be able to output 1.5 kW to the grid at any one time. So the inverter never got to strut its stuff as the load was never close to the rated 8.2 kW. (See battery section for update on this)

My other problem is that it is not a Hybrid inverter so cannot support a battery which is what I was originally planning. I guess I can only put it down to a lack of communication between myself and Green Choice Electrical to clearly state that my ultimate goal was to add a battery at a later date. They also did not ask the question.

So it means I have a second hand Fronius Symo 8.2 kW inverter for sale with less than 12 months use. All reasonable offers ;-) (having bought a new hybrid inverter to replace it)

Second Fronius at this site. Purchased identical unit to match the existing unit. Generally happy with the Fronius inverters. However, the cooling fan is very noisy. As part of this install, I had Springers' relocate the older Fronius from the garage to the carport. While the Fronius Datamanager is OK, I am a little annoyed at how Fronius "locks" the Datamanager with their password. While I can understand Fronius locking the inverter (to prevent naughty fingers from changing voltage settings), I fail to see why the Datamanager is locked, after all, it is my data.

(Update one year later) In general, really happy with the Fronius inverter. However, on niggle is that one of the firmware updates has thrown the internal clock out by a few minutes. In turn, this is throwing out my one minute data collection process. Nothing that has affected the functionality of the inverter. I would definitely buy a Fronius inverter again.

I did a fair bit of research and spoke with a lot of people and would have been happy to go with the Goodwe inverter however chose the Fronius as the price was not that different, it came with a 10 year warranty like the Goodwe (some installers can offer a 10year Fronius warranty) and the company has been around a significant amount of time.

Hi Dennis.
Thank you for choosing Fronius Gen24. The Fronius Gen24 Plus along with the Fronius smart meter would definitely help you in future proofing your energy demand. The self consumption values could be obtained from the Fronius smart meter which can further help you to decide if you plan to add batteries down the lane.

The inverter installed is a 10kW Symo 10.0-3-M (I have a three-phase setup). We are about five months into using the system and it has worked well. It may be too early to say how well this inverter functions from a reliability perpective. On the other hand, the Fronius system comes with access to data via the Solar.web app (and internet site). The data provided is quite granular and I expect this will help in understanding the performance of the system down track.

We have also purchased a subscription from Solar Analytics to provide additional monitoring data.

Each day the system shuts down with a message - 'Status Code 102 - AC Voltage too high'. I understand that this has something to do with the load being fed back into the grid and 253 volts. United Energy were to monitor this and make some form of adjustment but this never happened. The shutdown is only for short periods so it is not a worry.

It manages the hot water system via the smart meter and a relay ,which judiciously uses bits of excess power that would otherwise feed to the grid, and we have never had to use grid boost even on cloudy days. This saves us having a separate solar hot water system on the roof and yet still gives us a big system. The element has been downsized to 1800W but that has proved perfectly adequate for a 315L nominal system.

System has been operating for about 2 weeks since installation. No issues and ability to monitor output remotely is useful. Inverter is Fronius SYMO 8.2-3-M, 3 phase.

We opted for the Fronius Primo 5 Int and Fronius Smart Meter (optional extra). If you like to monitor how much electricity your system produces and you use, it is useful, especially when first trying to change habits like when you do the washing, vacuuming etc. I can't comment on the inverter as yet as the system is not turned on. Fronius recommended and used by installers.

Was contemplating between the SMA Tripower and Fronius Symo but went for the latter instead given it's reputation as among the top brands in the inverter market with quality build, excellent after-sales support and warranty. Also liked the active-cooling and snap-on design better.

I haven't had it long enough to answer that, so I just chose "Good". But it's a premium brand - solarquotes analogised it with a BMW. It's got a 10 year (5+5) warranty. BTW, Goliath organised the 5 extra years warranty (a Fronius offer till the end of 2019) for me.
