The Best Home Batteries In Australia In 2025: According To Aussie Installers

According to installers we trust, what are the best home battery brands in Australia in 2025?

Two brands tied for this year’s top spot – read on to discover the victorious duo.

How Did We Survey Our Installers?

We asked the 594 installers in the SolarQuotes installer network one question:

If installing a system on your own house today, what brand’s batteries would you use?

161 replied. Here are the results – including the two brands sharing the crown.

Best Home Batteries In Australia: 2025

Best Home Batteries 2025: First place – Tesla & Sungrow

Last year, Tesla dominated with 53% of the vote, while Sungrow barely secured third with 10%.

It’s remarkable how Sungrow has closed the gap with Tesla, which won gold every year since 2021. In a way, it’s just as interesting to see how far Tesla has fallen—despite still taking first place!

Is it Elon’s transformation into a hardcore Trumper? Is Tesla’s new Powerwall 3 not as good as the Powerwall 2? Is Sungrow simply offering a great product for a great price?

I’ve had my Powerwall 2 since 2016, and I installed a Sungrow battery on my rental property in 2023.

Both have performed well, with the Tesla App being a joy to use—but it’s not without its bugs. For example, the Tesla App’s ‘Charge-On-Solar’ feature broke about three months ago and refuses to charge my car from my 20kW of solar. I’ve now given up on it and pay $7 per month to ChargeHQ for solar charging instead.

The Sungrow is an excellent battery, although the Sungrow hybrid inverter has had some teething problems. Its modular architecture is a great feature. I added an extra module —and it was as easy as advertised.

Best Home Batteries 2025: Second place – Sigenergy

In my Best Inverters for 2025 blog, I mentioned that Sigenergy is the new kid on the block in Australia. It seems to have taken installers by storm, rocketing to second place in its first year with 17% of the vote.

I’d heard the buzz about their Sigenstore all-in-one system—especially its optional 25kW bi-directional DC EV charger—so I had to see one being installed.

I saw firsthand how easy they were to install and commission—everything worked flawlessly on the first try.

Sigenergy also appears increasingly often in quotes that my team reviews, proving it’s more than a niche player.

With their momentum, I wouldn’t be surprised if they take first place next year. I wouldn’t be too upset to see first place go from Elon’s Sieg heil to China’s SigEnergy¹.

Best Home Batteries 2025: Third place – BYD.

Falling from second place last year, BYD has taken third with 12% of the vote.

Austrian Fronius and Chinese BYD partnered years ago. BYD batteries are designed to DC-couple with Fronius’ latest Gen24 inverter range.

From everything I’ve heard, they’re a great battery, so you’d need a pretty compelling reason to get anything other than a BYD if you’re getting a Fronius inverter.

What Do These Batteries Cost?

My battery storage comparison table shows pricing for all the winners, plus heaps of other brands.

To keep things as apples-to-apples as possible, I’ll use the 13.5kWh of storage the Tesla Powerwall 3 has as the benchmark to compare the other modular battery brands:

• Tesla Powerwall 3 (13.5 kWh) – $13,600
• Sungrow SBR HV (12.8 kWh) – $9,500
• Sigenergy Sigenstor (13 kWh) – $11,500
• BYD HVM (13.8 kWh) – $10,600

Note that these prices don’t include installation costs, which generally run around $2,000 for the typical home, or hybrid inverter costs for the Sungrow and BYD batteries. Expect to pay more for installation if something about your place makes installing a battery tricky.
