You might be surprised to hear this, but just because a solar brand is well-known doesn’t mean it will last or offer the best quality. In fact, for some big names, years of experience can actually hold them back.
The Australian solar market is changing quickly. SMA, the German company known for its solar inverters, has already left the residential market here.
Fronius, another major European brand famous for its solar and hybrid inverters, is facing similar challenges.
At the same time, Sigenergy, a Chinese company that’s only two years old, is already making one of the world’s top home battery systems.
At PSC Energy, we’ve worked with SMA and Fronius inverters, and now Sigenergy batteries. We’ve seen what happens when a brand falls behind, and what it looks like when a company gets things right from the start.
In this article, we’ll cover the following topics:
- What Happened with SMA Solar Inverters in Australia
- Is the Fronius Inverter Next? An Honest Look at the Risks
- Why the SMA Inverter and Other Legacy Brands Struggle with Batteries
- Why Sigenergy Is Winning
- Not Every Battery Lives Up to the Hype
- FAQ: Fronius Solar Inverters, SMA Solar Inverters, and Sigenergy in Australia
By the end, you’ll understand why it’s important to choose a company that will be around for the long haul, and what to do if your inverter manufacturer leaves the market.
What Happened with SMA Solar Inverters in Australia
SMA has been making inverters for decades, and their products were once seen as some of the most reliable available. Here’s the current situation:
- SMA solar inverters are no longer offered for new residential installations in Australia.
- SMA still operates in the commercial and industrial market, so the brand hasn’t disappeared entirely.
- If you already have an SMA inverter at home, you still have support, but things aren’t quite the same as before.
- SMA made this decision because profits were shrinking and competition was increasing. We’ve seen this happen with other brands too.
SMA solar inverters have had very few warranty claims, which shows they’re high quality. Still, even a great product doesn’t mean a company will stay in the market long-term.
Is the Fronius Inverter Next? An Honest Look at the Risks
Fronius solar inverters have been popular for years, and Fronius Australia has had a strong local presence. But now, the same challenges that led SMA to leave are affecting Fronius too:
- Newer, more agile manufacturers offer better value and faster innovation.
- Because Fronius has focused on traditional inverter designs for so long, it’s harder for them to create battery storage that can compete with newer brands.
- Quality alone hasn’t been enough to keep other brands in the Australian residential market.
There’s no official word that Fronius will leave the market, and we’re not saying they will. Still, it’s reasonable to wonder about their long-term plans.
If you already have a Fronius inverter, there’s no need to worry right now. It’s a good idea to ask your installer what your options would be if things change.

Why the SMA Inverter and Other Legacy Brands Struggle with Batteries
Imagine you’ve spent twenty years perfecting petrol engines, and now you’re asked to build an electric motor. You might try to use what you know about petrol engines, but electric motors are different, and your old experience can actually get in the way.
This is what’s happening with inverter companies as they try to make batteries.
- Modern batteries work best with DC-coupled systems, where DC power is fed directly into the battery. It’s more efficient and safer.
- An engineering team built around AC faces a genuine structural challenge in designing a competitive DC-coupled battery.
- The same engineers who designed the original inverters are often tasked with designing the batteries. Without fresh leadership, you get the same results in new packaging.
What worked in the past won’t always work for the future.
Why Sigenergy Is Winning
Sigenergy has only been around for about two or three years. That might seem risky at first, but in reality, it’s actually their biggest advantage:
- They don’t have old products to protect, outdated systems to work around, or engineers stuck on old ways of thinking.
- Everything they make is designed from scratch with the latest battery technology in mind.
- The Sigenergy battery combines solar, storage, and energy management in one unit. It’s quick to set up and simple to use.
- Its three-phase capability makes it a good fit for many Australian homes, even larger ones with bigger energy needs.
- The price is competitive, offering good performance and value.
When Sigenergy faced a significant single-phase product recall, they handled it transparently and decisively; a more mature response than we’ve seen from brands around for decades.

Not Every Battery Lives Up to the Hype
There are lots of battery brands in Australia. They all say they have the best battery, so it can be tough for homeowners to know who to trust.
- Many new batteries are single-phase only, limiting how much stored energy you can use at once.
- Some systems match large batteries with small inverters. For example, a 50 kWh battery on a 5 kW inverter would take ten hours at full power to empty. Most households don’t use energy this way, so a lot of that battery’s capacity is wasted.
- Just because a battery is popular doesn’t mean it’s the best choice. Some of the most talked-about batteries are only popular because they’re inexpensive.
- The best battery for you depends on how you use energy, the size of your inverter, and whether you need single-phase or three-phase power.
Wrapping Up: AC/DC (Always Choose Disruptive Companies)
How long a brand has been around isn’t a good way to judge anymore. Well-known European brands like SMA have already left the residential market, and others are facing similar challenges.
- If you own an SMA or Fronius solar inverter and are worried about long-term support, speak with your installer.
- If you’re buying solar or adding a battery now, focus on the product itself, the local support, and the manufacturer’s track record in Australia, not just how old the brand is.

At PSC Energy, we work with you for the best, customised system available. The best solar system isn’t always the one you know best. It’s the one that will still work well and be fully supported ten years from now. Fortunately, we install them. It’s what we do.

FAQ: Fronius Solar Inverters, SMA Solar Inverters, and Sigenergy in Australia
Is SMA still operating in Australia?
SMA has exited the residential market but remains active in commercial and industrial. Homeowners looking for a new SMA solar inverter will need to consider alternatives.
Is my existing SMA solar inverter still supported?
You’re not immediately without support. Warranty claims on SMA solar inverters have historically been low, which is a positive sign. Still, talk to your installer about long-term options.
Is Fronius still operating in Australia?
Yes. The Fronius solar inverter remains a popular choice, and Fronius Australia is active in the residential market. Ask your installer about long-term support before you buy; the same pressures that led SMA to exit are pressing on Fronius.
How does the Fronius inverter compare to newer alternatives?
The Fronius solar inverter is reliable, but like other legacy European brands, Fronius struggles to develop competitive battery storage. Manufacturers building from scratch have a design advantage that older architecture can’t match.
Why is Sigenergy becoming popular?
The Sigenergy battery is an all-in-one home energy storage system designed from the ground up using modern technology. They’ve earned installer trust by delivering a quality product and handling issues, including a single-phase inverter recall, transparently.
What should I look for when choosing an inverter or battery brand?
A committed Australian presence, a strong track record of handling warranty claims honestly, and products built with modern technology. Also, ask whether your installer will back you up if a manufacturer reduces its presence in Australia.
