The beating heart of any solar system is its inverter, and nobody knows them better than the experts who work with them daily. It’s time to announce the winners of the 2025 SolarQuotes Installers’ Choice Awards for Best Solar Inverters.
How Did We Survey Our Installers?
At the time of writing, we have a whopping 594 installers in our network across Australia.
161 found the time out of their busy schedules to respond to our survey.
We asked them one simple question:
If installing a system on your own house today, what brand’s solar inverters would you use?
Here are the results. Drumroll, please.
Best Solar Inverters In Australia: 2025
Best Solar Inverters 2025: First Place – Fronius
A Fronius Gen24 inverter, installed by MC Electrical
Surprising no one, high-end Austrian manufacturer Fronius won gold for its 5th straight year, with 26% of the vote.
Their reputation in Australia borders on legendary, known for providing well-supported, reliable products.
The Gen24 series is Fronius’ current residential inverter, featuring a huge central fan and heatsink to keep it cool. Almost all of Fronius’ competitors avoid fans, relying on just a heatsink. The downside of a fan is noise, but the Gen 24 emits only a gentle hum. The upside of a fan is that it keeps the inverter cooler, theoretically improving efficiency and longevity.
Notably, Primo single-phase inverters are battery-ready, but you need to pay about $1,000 when you get your battery to update the inverter software.
On the SolarQuotes website, Fronius inverters have an average consumer review score of 4.8/5 based on over 8,600 reviews—a fantastic average score.
Best Solar Inverters 2025: Second place – Sungrow

Sungrow has made it on the podium every year since we started these awards in 2021. This year, they took silver with 19% of the vote.
They have a reputation for being a reliable, midrange inverter brand with a rock-solid battery pairing.
Their SGRS and SGRT comprise their core residential offering, with SHRS and SHRT as their hybrid inverters, designed for pairing with the SBR HV series of batteries.

On the SolarQuotes website, Sungrow inverters have an average customer review score of 4.7/5 based on over 4,000 reviews.
One disadvantage of the Sungrow hybrid inverter architecture is that the backup circuits go through the inverter in such a way that if the inverter fails, you lose power to those circuits. The simple way to mitigate this is to always install an emergency bypass switch with any Sungrow hybrid inverter.
Best Solar Inverters 2025: Third place – GoodWe
A GoodWe DNS inverter, installed by In Series Electrical and Solar
Taking bronze with 14% of the vote, GoodWe makes reliable budget inverters. They have a reputation for being simple to install and are a favourite among many installers.
Since Goodwe units are thousands of dollars cheaper than premium brands like Fronius, many installers and customers opt for them. At the end of this post, I’ll quantify the price difference between all the winners.
On the SolarQuotees website, Goodwe inverters have an average customer review score of 4.7/5 based on over 2,500 reviews.
Best Solar Inverters 2025: Special Mention – Sigenergy
The top module with the logo is the Sigenergy hybrid inverter module. The two modules below it are batteries. Installed by Energy Solution Centre.
Although it lost out on bronze by two votes to Goodwe, Sigenergy deserves a mention as an up-and-coming brand that burst onto the Australian solar scene in 2024.
It’s the early days, but installers like how easy it is to install and commission Sigenergy units, with a great-looking app that is heavily influenced by Tesla’s app (and that’s a good thing).
Price-wise, they sit between midrange Sungrow and premium-end Fronius.
I filmed the installation of a full Sigenergy system—and was impressed.
What Do They Cost?
Pricing at the inverter level can be seen on my standard inverter and hybrid inverter comparison tables.
To use an example – here’s pricing for a 10kW single-phase inverter:
- Fronius Gen24 10.0 Primo: $3,700
- Sungrow SG10RS: $2,300
- Goodwe GW10K-MS-30: $1,300
- Sigenergy 6.0kW (they don’t do 10kW single phase): $1,800
So the budget Goodwe will save you over $2,000 compared to the premium-end Fronius.
The question for consumers is: Is Fronius’s reputation worth $2k more, compared to the budget Goodwe? That’s a decision for you to make.
