Sigenergy Battery Review: Australia’s #1 Solar Battery Brand?

If we asked you to name the number 1 solar battery manufacturer in Australia, what would you guess? Tesla? LG? Sonnen? Sigenergy?

Wait, Sig … what?

That’s right: according to the latest industry data from SunWiz, Sigenergy – a relatively new name on the scene – took the top spot for battery market share in Australia in March 2025. And while many Australians haven’t even heard of a Sigenergy battery yet, that’s about to change.

As the federal government’s new solar battery rebate kicks in from July 1, there’s never been a better time to look into energy storage. If you’re searching for solar battery quotes, or just trying to understand which brands are worth considering, our exclusive solar battery review takes a closer look at the quiet achiever: the Sigenergy battery.

Who is Sigenergy?

Sigenergy is a Chinese clean energy company founded in 2022 and headquartered in Shanghai. In just a few years, they’ve rolled out their innovative battery systems to over 60 countries – and now, they’re leading the Australian residential market in terms of monthly kWh installed.

They’re best known for their flagship product: the SigenStor. It’s a sleek, all-in-one modular energy solution that combines:

• A solar inverter
• Battery storage
• EV charging
• And AI-powered energy management in a single stackable unit.

This rapid growth has been driven by a combination of cutting-edge engineering, installer-friendly design, and strong local distribution – including through trusted Australian providers like Static Electrics.

Why are Australians choosing Sigenergy?

So how did a brand new player edge out long-established brands in the Australian market?

There are a few reasons:

Modular Capacity: The SigenStor battery is stackable, allowing households to expand their storage from 5 kWh up to 48 kWh depending on usage. You don’t have to overinvest upfront – you can grow your system over time.

All-In-One Integration: Rather than installing a separate battery, inverter, charger, and control system, Sigenergy combines them into one unit. That means:

• Faster installs
• Fewer points of failure
• And a cleaner look.

EV Charging Built In: Unlike most battery brands, Sigenergy includes optional EV DC charging as part of its system. That’s a game changer for homeowners planning to add an electric vehicle in the next few years.

Smart Software: Sigenergy’s AI-driven SigenCloud platform lets you monitor, automate, and optimise your home’s energy usage – even remotely. It’s a major upgrade over clunkier apps used by older brands.

Installer Support: For solar companies, Sigenergy systems are fast to commission and come with advanced remote diagnostics, meaning less time on-site and fewer call-backs. That makes them an attractive option for trusted local installers.

How does it compare in the real world?

It’s one thing to have clever specs on paper – but does it hold up in the real world? Here’s a solar battery review of how the Sigenergy system compares on the ground.

Efficiency: The Sigenergy system offers round-trip efficiencies around 89-92%, depending on configuration. That puts it in line with industry leaders like Tesla Powerwall and ahead of many older lithium iron phosphate (LFP) options.

Safety: All modules are LFP-based (LiFePO4), known for excellent thermal stability and long lifespans. Each stack has built-in monitoring and safety shutoffs – features you’d expect from a Tier 1 brand.

Compatibility: While the system works best as an all-in-one install, Sigenergy’s battery modules are compatible with a range of solar setups and can be retrofitted in many cases.

Design: It’s compact, minimalist, and wall or ground-mountable. Unlike many boxy systems, Sigenergy units have a more integrated, architectural look.

Noise & Maintenance: Extremely quiet operation with minimal servicing needed. The cloud platform provides automatic alerts and firmware updates.

If you’re comparing options based on customer solar battery reviews, early feedback in the Australian market has been strong. Most reviewers highlight the simple installation, fast performance, and aesthetic design.

Sigenergy in the age of the federal battery rebate

With the new federal solar battery rebate scheme rolling out in July, Australians can now get a 30% discount on eligible battery storage systems through the Small-Scale Renewable Energy Scheme (SRES).

This makes 2025 the perfect time to consider upgrading your system – or finally installing a solar battery in Brisbane or the Sunshine Coast if you’ve been on the fence.

The Sigenergy battery is expected to qualify under the scheme, as long as it’s installed by a Solar Accreditation Australia (SAA) accredited installer. And that’s where Static Electrics can help!

If you’re getting solar quotes battery comparisons or reviewing other brands, it’s worth looking at how Sigenergy stacks up in value – especially with rebate eligibility factored in. It may well offer more functionality per dollar than some better-known brands.

Is Sigenergy right for you?

As with all battery decisions, the right solution depends on your specific needs:

• Want a modular system you can grow over time?
• Interested in EV charging now or in the future?
• Looking for a modern, app-connected solution with smart automation?
• Keen to get the most out of your solar under the new rebate scheme?

If so, Sigenergy is absolutely worth including in your solar quotes batteries shortlist.

On the other hand, if you’re in a remote location, or have very specific compatibility requirements, a site visit from an installer like Static Electrics can help you assess whether Sigenergy is the right fit for you – or whether another system makes more sense. We’ll be upfront and honest about what we think is best just for you.

A quiet leader worth watching

Sigenergy may not be a household name – yet – but it’s leading the Australian market in 2025 for a reason. From stackable batteries and integrated EV charging to sleek design and installer-friendly engineering, it’s bringing serious innovation to a market that’s long overdue for it.

Whether you’re researching options for your first solar battery, or you’re ready to take advantage of the federal rebate, this is the time to explore what’s new – not just what’s already familiar, as tempting as that is.
