Fronius Solar Inverters: An Independent Review by Solar Choice

Solar Choice CEO Jeff Sykes gives a rundown of Fronius as a company and their 5kW Primo inverter.

This Fronius inverter review is performed independently by Solar Choice and has no affiliation with Fronius.

Overview of Fronius – Company History

Founded in Austria on June 20th 1945, Fronius is an international company with a 75-year history in the manufacture of welding equipment and nearly three decades of experience with solar inverters and other devices for monitoring and controlling energy, including battery chargers.

Fronius launched its first grid-connected solar inverter back in 1995. Since then Fronius has grown to become one of the industry leading solar inverter manufacturers, with 19 of 28 offices worldwide being involved with solar energy. This includes the Australian office located in Tullamarine, Victoria.

Fronius inverters are suitable for a wide range of applications, including residential solar and commercial solar projects, including their recently launched Fronius Tauro inverter with 100kW capacity.

A Brief Rundown on Solar Inverters

A solar system’s inverter is the point at which the DC electricity produced by solar panels is turned into grid-compatible AC electricity.

String inverters have traditionally been the standard in the solar industry. They send the power produced by solar panels to a central inverter that changes it from DC electricity to usable AC electricity that powers homes.

Microinverters, on the other hand, convert DC to AC electricity at each individual panel and allow for monitoring and power regulation at the panel level. This is useful for homes that are located somewhere with shading from clouds, trees, or other buildings.

What is PV Evolution Labs Top Performer?

PV Evolution Labs (PVEL) independently test solar inverter reliability. The tests are voluntary, with solar inverter manufacturers paying to participate in the testing. This testing process is internationally renowned and is an accurate reflection of the solar inverter’s performance. To read the full PVEL scorecard click here.

In 2019 Fronius Symo ranked as a top performer in the following tests:

  • High-Temperature Operation
  • Transient Response
  • Ground and Arc Fault

How Much Do Fronius Inverters Cost?

As Fronius inverters are manufactured in Europe this higher quality product comes with a higher price tag in comparison to the inverters that are manufactured in China.

The most popular Fronius GEN24 Primo 5kW model retails for about $2,200 to $2,400, which excludes installation and any additional required wiring and components.

Keep in mind that inverter costs generally only run between 10-20% of your total system, so often it is worth investing in a high-quality inverter given this will have a large impact on the efficiency and performance of your entire system.

Fronius Inverter Review – Point of Difference

There are many solar panels out there, what makes Fronius inverters stand out?

The most used premium inverter brand in Australia

Fronius SnapINverters

Fronius has earned a strong reputation for its high-quality inverters, advanced technology, and excellent customer support. Their inverters are widely used in residential, commercial, and industrial solar installations across Australia. Based on information from Solar Choice’s database of residential solar quotes, Fronius has maintained over 50% market share of installers’ premium options.

Monitoring and Data Communication

Fronius inverters offer advanced monitoring capabilities, allowing real-time access to energy production and system status through mobile apps and web portals. This data empowers users to detect and resolve issues promptly, optimise energy usage, and integrate with smart home systems and energy management platforms for more efficient energy consumption.

Fronius Inverters Technologies

A unique aspect of Fronius inverters is the SnapINverter technology. It’s a standardised wall-mounted bracket with the inverter on a hinge system. This enables easy access for servicing as the inverter opens like a car boot, without needing to be removed from the wall.

The majority of Fronius’s Inverters are approved by the Clean Energy Council for the Small-scale Renewable Energy Scheme, which is Australia’s home solar rebate program.

Fronius GEN24 Primo

Fronius GEN24 primo inverter 5kW

The Fronius Primo series is designed primarily for residential household applications with power ranging from 3.0kW to 10kW. These inverters are single-phase inverters, meaning they are suitable for smaller solar PV systems typically found in homes.

The newer GEN24 series has dropped the LCD screen which displayed the real time performance of the system and has replaced with status lights. The GEN24 series includes their Dynamic Peak Manager which helps the inverter improve output in shaded situations without any optimisers or micro-inverters installed on the panels.

Contrary to many other inverter manufacturers, Fronius has stuck with active cooling with a built in fan. This may mean that the inverter makes a bit more noise, but Fronius argue that it improves the service life of their products.

The Fronius Primo also comes in a GEN24 Plus option which is Fronius’ hybrid version suited to connecting a battery to the system. All other features and appearance remain similar to the GEN24.

Fronius SymoFronius Symo

These inverters are three-phase inverters that are suited to larger residential homes and small commercial projects. The power range of Symo is from 3.0kW to 20kW. 

The Symo series offers higher efficiency and the same advanced features as the Primo series, including reactive power control and support for dynamic grid conditions

Fronius EcoFronius Eco

The Fronius Eco is a transformerless three-phase inverter designed for medium to large-scale commercial solar systems. The commercially used inverter comes in 25kW or 27kW power ratings. The Fronius Eco inverter holds an Ingress Protection Rating (IP Rating) of 66, which means it’s dust-tight and able to withstand heavy seas or powerful jets of water. Both power categories hold an efficiency rating of over 98%.

Unfortunately, the 27kW inverter is not well-designed for the Australian market where inverters are able to extend to 30kW without requiring extra network protection. The optimal design for many small businesses is to use a 30kW inverter and extend the solar panel capacity to 39.9kW, while the Fronius Eco 27kW can only support 35.9kW of solar panels.

Fronius Inverter Efficiency

In Australia, all CEC-approved Fronius inverters come with a 5-year warranty for parts and labour. A free additional 5-year extension (parts only) to the warranty can be claimed by, registering at solarweb within 30 months of the factory inverter dispatch. This means in the first 5 years Fronius will cover most of the labour and shipping associated with any covered repairs or replacements. In years 6 – 10 the customer will bear that cost.

This is definitely now below what is the standard for an inverter warranty in Australia. Most inverter companies offer 10 years full coverage including labour, including both of Fronius’ European competitors SMA and Fimer.

A full warranty extension can also be purchased from the inverter installer within 30 months of the inverters dispatch from the Fronius factory. This can extend the full parts and labour coverage to a total of 10, 15, 20 or 25 years.

Fronius do have a local office and excellent local support for their customers looking to resolve issues with their system.

So, Should I Buy Fronius inverters?

We consider Fronius as the premium option for both residential and small commercial uses. Fronius is one of the longest-standing brands in the solar inverter market with an excellent reputation. 

In recent years, many of the Chinese solar inverters have caught up to Fronius (and in some cases overtaken) when it comes to the technical performance characteristics of the inverter. Fronius’ point of difference comes from the long track record they hold in terms of reliability and after-sales support. 

In our opinion, you can’t go wrong with Fronius, and it would be worth paying a bit more to go with this brand over many of the others in the market.

Example of a Fronius Commercial Solar Project 

The Philippines has seen quite a rise in the number of solar systems being installed over the past few years. This is due to the public grid being unable to reliably supply power to the 13 million Filipinos living in the metropolitan area surrounding Manila.

Fronius Field Installation TARLAC CITY, PHILIPPINES

In April of 2019, a field located in Tarlac City, Philippines had a 20MW system equipped with 612 Fronius Eco inverters go live. The system included 61,200 solar panels to total the 20MW, the installation was completed in 5 months.

By installing the Fronius Eco the overall potential yield of the panels was increased. Although, for an installation of this magnitude it is unusual for the inverters used to be string inverters. However, it is because of the string inverters that the system is able to be more efficient. String inverters work better in conditions such as partial shade compared to central inverters. It was estimated that the system will produce around 32,000MWh of electricity, reducing CO2 by around 18.6million kg.

Love the app, have been looking at it the last couple days! Very informative and with the consumption meter, I'm constantly looking at ways to reduce buying from the grid. I know a few people that have had Fronius installed for a few years now and cannot fault them, plus Fronius has been around for a long time, so I feel comfortable in making the right decision. I really like the look of the GEN24 too!

Inverter looks and works great. The app connects giving a lot of information. The direct connection to the system by IP address gives a lot of control. The only problem I have had was when I wanted to do a system reset and couldn't remember the sequence. Fronius tech support were very patient and talked me through the process and waited while the system came back online. He then pushed a system update through. I can't rate Fronius highly enough.

The Gen24 inverter is fine after 18 months. However, the Solar.web app is very poor. When it works the data is adequate, but for months the app could not connect to the inverter via wifi and I had no output data. I fixed this by connecting an Ethernet cable from the inverter to the router. Now in Feb 2024 Fronius has “updated” the app and it now takes 20 seconds to load on my iPhone, which is irritating. The in-app instructions to modify settings as a Technician are also very unintuitive. Get something better if you can.

I did thorough research online and went with Fronius GEN24 inverter and one of the recommended solar installers Essential Solar. My solar system got install in July 2023. The inverter ran for less than a week then it stopped working totally. I reported to the installer immediately, Essential solar couldn't find the problem; then reported it to Fronius; Fronius Australia couldn't find the problem; then reported to Fronius International. The whole "kicking the ball" process took them 2 whole weeks 14 days! During this period, none of the companies bother send their technician to come to my house to give an actual diagnoses for the problem. After two week, they eventually showed up with an electrician and find a tiny issue that could be solved immediate onsite! 7 months on, here comes my 2nd bad experience - again the Fronius GEN24 inverter stopped working on Tuesday 13th Feb. at 15:31 immediately after the catastrophic weather conditions in Melbourne. I live only 9km from city so we didn't experience power outrage or anything too serious in the whole area. I reported it to Essential Solar on Wednesday morning 14th. The whole "kicking the ball" process starts again! The technical from Essential Solar can not diagnose the issue remotely, it was then passed to Fronius Australia, and now I was told it has been escalated to Fronius International. I am still waiting... no one has come to my house to even have a look, all done remotely! I have been paying my electricity bill since the inverter broke down, and we have experience few hot days and today will be another 38C but I can't use my solar energy! I won't recommend Fronius to anyone as their service is the worst! Don't expect to get problem solved quickly as their technicians are not capable to doing so quickly.

The Fronius Gen 24 inverter has a fan which comes on and off but is unobtrusive and quiet even though it is close to the door to our living area. I have read comments relating to earlier series inverters and noise but we have not experienced that and you need to be close to hear the fan. The supplied Solar.web app works well and reports on immediate power generation and also daily, monthly and yearly generation. It has worked faultlessly.

We chose the Fronius brand inverter due to the reputation the brand has world wide. The Quality Solar System reps. felt that as a 'top of the range' brand, we had made the right choice. We opted to have the inverter installed inside the garage. There was the usual 'mess' from the drilling of the garage wall for the inverter and associated switch but everything was left 'spick and span' at the end of the installation. The inverter display is easy to read but as I am not a tech nerd, not too easy to interpret. The installing tech. however stated that so long as the green 'ON' light was illuminated, I could rest assured that the Fronius was doing it's job. I also have the Fronius App on my phone but it also is a bit difficult to understand. The system did trip it's circuit breaker twice but Quality Solar's rep. and electrician were at our house within an hour and the 'problem' rectified. The system has also been setup by Quality Solar Systems to email a log of unusual events which is reassuring.

A little bit noisy in operation, especially when starting up at the start of daylight and closing down at the end of the day. Otherwise excellent. Note that I was aware of this issue - noise- (from reading reviews and owner comments), but as system is installed in/on a large farm shed, it does not intrude on house with the noise generated.

I consciously choose an expensive inverter (but I had no need for sophisticated one). This is a critical component, and I wanted to have open access to it with reliable API and known protocol (so that I could gather statistics independently, without 3rd-party tools). But this may not matter for most. Fronius Primo is clearly a well-designed unit with enough customisation, which is pleasure to work on, and which worked flawlessly so far (1.5+ years). The only thing that the users should be conscious about: it has a fan, which can get appreciably noisy when the power output is close to maximum. (It will be practically silent at night and most times in winter). Don't install it next to windows and doors, if possible.

This system is Off Grid but the Grid is present as a manually switched backup. The Fronius is electronically coupled to a Selectronic SP PRO which acts as the battery inverter and charger and controls the 240v to the house. The Fronius is there to convert Solar DC to 240v which is AC coupled to the Selectronic.
