How Sungrow Won the Australian Inverter Market (2026)

In April 2026, SMA exited the Australian residential market after more than 15 years. The same month, Sungrow collected three number-one rankings at the 2026 SunWiz Awards, including top residential inverter, top commercial inverter, and top commercial energy storage system.

How did a Chinese manufacturer overtake one of Germany’s most respected engineering firms? And what does this shift mean for Australian homeowners choosing an inverter today? We break it down below.

How Do SMA and Sungrow Compare in 2026?

SMA has withdrawn from Australian residential solar while Sungrow now holds the number-one position across three categories. The gap between the two brands widened sharply through 2025 and into 2026. SMA posted losses exceeding €65 million in 2025, cut 1,100 jobs worldwide, and announced 350 more cuts planned for 2026. Sungrow moved in the opposite direction, growing market share and expanding its local support network.

Five years ago, SMA still held a strong position. That position no longer exists.

Why Did SMA Leave the Australian Residential Market?

SMA could not sustain the pricing pressure and product gaps that had eroded its residential position for years. According to PV Magazine Australia, SMA CEO Jurgen Reinert confirmed the company would refocus entirely on Australia’s utility-scale solar segment. The decision followed a string of financial setbacks, strategic missteps, and mounting competitive pressure.

The Glory Days

For over a decade, SMA was the default choice for quality-focused Australian solar installers. The German manufacturer brought disciplined engineering, strong build quality, and proven reliability. SMA supplied technology to early Australian utility-scale projects such as the Greenough River Solar Farm, the Royalla Solar Farm, and the Moree Solar Farm.

At its peak, SMA had supported over 10GW of solar installations across Australia. The Sunny Boy became one of the most recognised residential inverter brands in the country.

Where It Went Wrong

SMA’s decline resulted from four compounding failures, not a single mistake.

1. No battery strategy. As Australian homeowners moved toward solar-plus-storage, SMA had nothing to offer them. They never developed their own battery product. Their battery-compatible units like the Sunny Island, Sunny Boy Storage, and the late Sunny Boy Smart Energy were expensive and awkward compared to the integrated solutions from competitors like Sungrow, Tesla, and Enphase.

2. Premium pricing in a price-driven market. SMA inverters often cost double the price of Sungrow equivalents. Many installers respected SMA’s quality, but price-sensitive customers and the installers competing for their business increasingly chose alternatives that performed within 2% efficiency of SMA at half the cost.

3. Slow product development. The Australian market moved toward hybrid inverters with built-in battery management, fast backup power, and integrated monitoring apps like iSolarCloud, FusionSolar, and mySolarEdge. SMA’s product roadmap lagged behind, particularly in the residential segment where homeowners expected a single-brand solution.

4. Financial pressure. Losses exceeding €65 million in 2025 forced SMA into hard choices about which markets to keep. With 1,100 job cuts globally and another 350 planned for 2026, Australia’s fiercely competitive residential market was cut from the strategy.

What Makes Sungrow the Top-Selling Inverter in Australia?

Sungrow combines near-best-in-class efficiency with the widest product range and the lowest price point among tier-one inverter brands. That combination has made it the top-selling residential inverter in Australia for three consecutive years, according to the SunWiz Awards. While SMA was retreating, Sungrow was filling every gap SMA left open.

1. Unbeatable Value

Sungrow’s core advantage is price-to-performance ratio. Their inverters deliver up to 99% peak efficiency, matching or exceeding the SMA Sunny Boy’s 97.2%, at roughly half the installed price. For the average Australian household running a 6.6kW system, the real-world output difference between the two brands is negligible. The price difference is not.

Australian installers have voted Sungrow best value inverter for 3 consecutive years. That vote reflects thousands of installations and warranty claims, not marketing.

2. Complete Solar-Plus-Storage Package

Where SMA failed to build a battery, Sungrow went all-in. Their SH hybrid inverter series pairs directly with the SBR battery range, creating a complete solar-plus-storage package under one brand, one warranty, and one monitoring app. This matters for three practical reasons:

• Single point of warranty and support, eliminating finger-pointing between brands
• Guaranteed compatibility between inverter and battery, with no third-party adapters
• Sub-20ms backup switchover, fast enough to keep fridges, Wi-Fi routers, and medical equipment running during a blackout

3. Largest R&D Team in the Solar Industry

Sungrow operates the largest dedicated R&D team in the solar industry. This is not a low-cost manufacturer trimming corners. It is the world’s largest inverter manufacturer by shipment volume, investing heavily in firmware updates, new hardware generations, and grid compliance across markets like Australia, Germany, and the United States. The result is a product range that evolves rapidly, with new models arriving consistently.

4. Strong Australian Market Commitment

Sungrow maintains local offices in Sydney and Melbourne, runs installer training programs across every state, and provides direct warranty support through its Australian team. Their iSolarCloud monitoring platform receives regular updates. Buying Sungrow in Australia means buying from a company that treats this country as a priority market, not one preparing to leave.

How Do SMA and Sungrow Compare on Technical Specifications?

Sungrow’s SH hybrid series outperforms the SMA Sunny Boy on efficiency, battery integration, and backup capability while costing significantly less. Here is a direct comparison between the two brands’ flagship residential products.

The specifications show a clear pattern. Sungrow’s hybrid range delivers more functionality, higher peak efficiency, and a lower price.

What Did SMA Do Better Than Sungrow?

SMA set the standard for inverter build quality, monitoring software, and utility-scale grid technology over a 15-year track record in Australia. This comparison is not one-sided. SMA excelled in areas that still matter.

• Build quality and longevity. SMA inverters are built like industrial equipment. Many units installed 10 to 15 years ago are still running without a single fault. That durability is hard to match.
• Monitoring platform. The SMA Sunny Portal was one of the first professional-grade solar monitoring platforms. It set the benchmark that Sungrow’s iSolarCloud, Fronius Solar.web, and Huawei FusionSolar later followed.
• Utility-scale expertise. SMA remains a global leader in large-scale solar. Their grid-forming inverter technology supports some of the world’s largest solar farms. They have not left Australia entirely; they have refocused on this higher-margin segment.
• German engineering reputation. For some buyers, the “Made in Germany” label carried real weight and justified the premium price.

The lesson from SMA’s exit is not that they made bad products. They made excellent products. The lesson is that technical quality alone cannot sustain a market position when competitors offer 99% efficiency at half the price, a complete battery integration, and a local support network that keeps growing. SMA won the inverter market of 2015. Sungrow won the inverter market of 2026 by recognising that Australian homeowners now buy energy systems, not standalone inverters. The brands that survive in this market are the ones that deliver a full solar-plus-storage solution with local warranty backing, not just a well-engineered box on the wall.

What Should You Do if You Own an SMA Inverter?

Keep your SMA system running until it needs replacement, then upgrade to a Sungrow SH hybrid paired with an SBR battery. Your existing SMA inverter is still a quality product. SMA is honouring all warranties through a maintained local office in Australia. There is no rush to replace a working system.

When your SMA unit does reach end of life, the Sungrow SH series is an excellent upgrade path. Your existing solar panels from brands like Jinko, Trina, or LONGi will work with a new Sungrow inverter. A qualified installer will confirm compatibility and handle the switchover.

Which Inverter Should You Choose in 2026?

Sungrow is the best all-round choice for most Australian homes, combining the top SunWiz ranking with the strongest value proposition in the market. It offers the best balance of quality, features, and price. For homeowners who want a premium European alternative, Fronius remains an excellent option, particularly for those who value Austrian manufacturing, the Fronius Solar.web monitoring platform, and the Primo GEN24 hybrid range.

Why did SMA leave Australia but Sungrow didn’t?

SMA faced a cost structure that could not compete with Chinese manufacturers at Australian residential price points. They also never developed their own battery product, leaving a gap in their lineup as the market shifted to solar-plus-storage. SMA’s CEO Jurgen Reinert confirmed the company would refocus on Australia’s utility-scale sector. Sungrow, with its manufacturing scale and lower cost base, does not face the same pricing pressure. It continues to invest in local operations, new product launches, and installer training across Australia.

Will Sungrow leave Australia too?

That is extremely unlikely. Australia is one of Sungrow’s top global markets. They just collected three number-one rankings at the 2026 SunWiz Awards, they maintain growing local teams in Sydney and Melbourne, and they continue launching products specifically designed for Australian grid standards and climate conditions.

Is SMA still available in Australia?

SMA has exited the Australian residential and commercial inverter market. They no longer sell products like the Sunny Boy, Sunny Tripower, or Sunny Island for homes and businesses. They do maintain a local office for warranty support on existing installations, and they continue operating in Australia’s utility-scale segment for large solar farms.
