Choosing between a Sungrow and Fronius hybrid inverter in Brisbane comes down to balancing premium European engineering against outstanding Chinese value. Fronius, an Austrian brand, is the top choice for installers who prioritise build quality and long-term reliability, with its GEN24 Plus hybrid inverter costing around $2,800 to $3,500. Sungrow, a globally leading Chinese brand, offers its popular SH-RS hybrid inverter for a more budget-friendly price of approximately $2,200 to $2,800, providing a faster return on investment, typically within 5 to 7 years. Both brands perform well in hot climates and come with 10-year warranties, but Fronius is often praised for its active cooling technology and hassle-free warranty claims.
Sungrow vs Fronius: A head-to-head comparison for Australian homes
When deciding on the heart of a solar battery system, the hybrid inverter, two names consistently come up in Australia: Sungrow and Fronius. As a consumer advocate, I’ve analysed countless data sheets and spoken with numerous installers, and the consensus is clear: this isn’t a simple case of one being better than the other. It’s about choosing the right inverter for your priorities.
Fronius is an Austrian company with a long-standing reputation for premium engineering and exceptional durability. It’s often the top pick for Solar Accreditation Australia (SAA) accredited installers who value reliability and robust local support. Sungrow, founded in China, has become a global powerhouse by delivering high-efficiency, feature-rich inverters at a more accessible price point. In recent years, Sungrow has significantly closed the gap in quality and support, making it the preferred brand for homeowners focused on value and a quicker payback period.
Here is a high-level breakdown of how they compare:
| Feature | Sungrow (SH-RS Series) | Fronius (GEN24 Plus Series) |
|---|---|---|
| Origin | China | Austria |
| Market Position | Best Value / Mid-Range | Premium Quality |
| Price Point | More Affordable | Premium |
| Key Strength | Excellent value for money, high efficiency | Superior build quality, proven longevity |
| Cooling System | Passive (Heatsink) | Active (Fan and Heatsink) |
| Warranty | 10 Years | 10 Years (registration required) |
Sungrow SH-RS hybrid inverter review
The Sungrow SH-RS series is arguably the most popular hybrid inverter in Brisbane for homeowners seeking a balance of performance, features, and price. It’s known for being a reliable, quiet, and highly efficient unit that pairs seamlessly with Sungrow’s own SBR batteries.
Key Features:
-
High Efficiency: Sungrow inverters boast a maximum efficiency of up to 98.4%, ensuring maximum energy yield from your solar system. This means more of the energy from your panels is converted into usable electricity.
-
Value for Money: This is Sungrow’s biggest advantage. It offers features comparable to premium brands at a significantly lower upfront cost, shortening the payback period on your solar investment.
-
User-Friendly Monitoring: The iSolarCloud app provides real-time data on your energy production and consumption, helping you track your savings effectively.
-
Backup Power: The SH-RS provides a backup circuit that can power essential loads during a grid outage when paired with a compatible battery.
From my analysis of dozens of system quotes, choosing a Sungrow inverter can often save a homeowner between $1,200 and $1,500 on the initial installation compared to a Fronius system.
Fronius GEN24 Plus hybrid inverter review
The Fronius GEN24 Plus is the inverter of choice for those who believe in the “buy once, buy right” philosophy. Its Austrian manufacturing and robust components are designed for a 15+ year lifespan, offering peace of mind and exceptional long-term performance.
Key Features:
-
Active Cooling Technology: The GEN24 Plus features a large fan and heatsink system. This is a significant advantage in hot climates like Brisbane, as it keeps the inverter’s electronics cooler, improving efficiency and prolonging the unit’s life.
-
Advanced Backup Options: It offers a basic “PV Point” backup socket and a “Full Backup” option that can power the entire home during an outage (when installed with the right battery and switchgear).
-
Flexible Battery Compatibility: While it pairs perfectly with BYD batteries, the GEN24 Plus is known for its flexibility in working with a range of third-party battery brands.
-
Superior Support: Installers consistently praise Fronius for its excellent local technical support and straightforward warranty process.
Best hybrid solar inverters for Brisbane homes
For Brisbane homes, the choice hinges on your budget and long-term goals.
-
Choose Sungrow if: Your priority is achieving the fastest possible return on investment without compromising on core performance and reliability. It’s an excellent, cost-effective choice that makes adding a battery more accessible.
-
Choose Fronius if: You are willing to invest more upfront for premium build quality, superior performance in extreme heat, and the peace of mind that comes with a top-tier European brand.
Case Study: A Family in Chermside West The Tran family was dealing with quarterly power bills over $550. They installed a 6.6kW system using Trina panels and a 9.6kWh Sungrow SBR battery with an SH5.0RS hybrid inverter for a total cost of $14,800. After federal rebates, their initial outlay was closer to $11,000. Their annual savings are now projected to be over $2,100, putting them on track for a payback period of just over 5 years. Their last electricity bill was only for the daily grid connection fee.
Sungrow vs Fronius inverter performance in hot climates
This is a critical consideration for anyone living in Queensland. Electronics degrade faster in high heat, and an inverter’s efficiency can drop as temperatures rise. Fronius holds a distinct advantage here with its active cooling system. The fan actively dissipates heat, allowing the inverter to maintain more consistent performance on scorching summer days.
Sungrow inverters use a fanless, passive cooling design which relies on a large heatsink. While this makes them quieter, some installers have noted a slight performance dip in extreme heat compared to Fronius models. However, both brands design their inverters for harsh Australian conditions and operate effectively up to 60°C.
Gigi’s Pro Tip: Ask your installer to place the inverter in the garage or on a shaded southern wall of your house. Keeping it out of direct sunlight, regardless of the brand, is one of the easiest ways to maximise its performance and lifespan.

Sungrow: Provides a straight 10-year manufacturer’s warranty. While their support has improved significantly, some installers note the claims process can occasionally require more documentation than Fronius.
Installer recommendations in Brisbane
I spoke with an SAA-accredited installer last week, and they summarised the local sentiment perfectly: “If a customer wants the best and doesn’t mind the extra cost, we recommend Fronius every time. It’s bulletproof. But for 8 out of 10 customers, Sungrow hits the sweet spot—it’s reliable, does everything they need, and saves them a significant amount of money that can go towards a bigger battery.”
Most reputable Brisbane installers are happy to install both brands, recognising them as the top two contenders in their respective market segments.
Battery compatibility
Both inverters offer great “behind-the-meter” integration with smart meters and are designed to work seamlessly with leading battery brands.
-
Sungrow SH-RS: Is optimised for its own Sungrow SBR (Solar Battery Residential) series. It is also compatible with other high-voltage batteries, including some models from BYD.
-
Fronius GEN24 Plus: Is most famously paired with the BYD Battery-Box Premium HVS/HVM series. It is also compatible with LG battery solutions, offering excellent flexibility.
The final verdict
Deciding between Sungrow and Fronius is a great problem to have, as both are fantastic choices for a Brisbane home.
If your goal is to get the best value, a faster payback, and a high-performing system that ticks all the boxes, the Sungrow SH-RS hybrid inverter is an outstanding choice.
If you prioritise long-term durability, maximum performance in the summer heat, and the assurance of a premium European brand with rock-solid support, the Fronius GEN24 Plus is worth the extra investment.
