Labor’s election win means its $2.3bn Cheaper Home Batteries Program campaign promise is set to become reality. But which are the best brands to get under this new battery rebate, and how big are the savings?
Using SolarQuotes’ Federal Government Battery Rebate Calculator, here’s the estimated rough discount for the best battery brands in Australia in 2025, as voted by our network of installers.
The results of SolarQuotes’ Installers Choice Awards 2025 for best battery brand.
The estimated savings listed below are a rough guide only and exclude installation prices, which depending on your property and requirements could be around $2000. The value of the rebate is also set to depend on a fluctuating STC price, which we’ve put at $36 per STC for the purposes of this piece.
The finer details of the rebate itself are still being hashed out and it is only due to come into effect July 1, although you can claim it for batteries installed since the announcement of the rebate on April 6, as long as you the battery isn’t turned on before the start date of the scheme.
These savings also don’t include the financial benefits of double-dipping with state battery incentives.
The Sungrow battery offers the benefit of modular design, and can be expanded in 3.2 kWh increments.
Sungrow SBR HV
In equal first place in our Installer’s Choice Awards for Best Battery, Sungrow offers a rare combination of relatively low price and high-quality hardware with excellent tech support. Reviews on the SolarQuotes website for Sungrow batteries average an impressive 4.8 out of 5 star rating.
The Sungrow SBR HV is modular and so is available in a range of sizes. For this article we are assessing the 12.8 kWh version, for which you can expect the rebate to shave roughly $4,068 off the cost.
This takes the overall estimated retail cost from $9,500 down to $5432, not including installation.
The Tesla Powerwall 3 is a higher-cost option that has proved popular with users.

The other brand sharing the podium in top spot is Tesla, which has a good track record of providing reliable batteries and excellent customer service, explaining why they enjoy a strong rating of 4.9 out of 5 stars among SolarQuotes reviewers.
The company’s latest home battery is the Powerwall 3, which unlike Sungrow’s modular offering is fixed at 13.5 kWh of usable storage. The rebate should cut roughly $4,500 off the cost.
That takes the $13,600 estimated retail price down to $9,100, excluding installation fees.
Sigenergy is a relatively new arrival in the Australian home battery scene, but is growing quickly in popularity.
Sigenergy’s Sigenstore All-In-One
Only founded in early 2022, Sigenergy is the new kid on the block in terms of solar batteries but has already had a huge impact, with our installers rating it in second place in 2025 for its battery offerings.
Averaging 4.9 out of 5 stars on the SolarQuotes review hub, Sigenergy seems to be winning Australian hearts and minds with their all-in-one product offering, which can also include an optional 25kW bi-directional DC EV charger. For the single-phase 13kWh battery, the rough estimated rebate is $4,320.
That takes the $11,500 estimated retail price down to $7,180 excluding install costs.
One of the advantages of BYD batteries is that they play nicely with high-quality Fronius inverters.
BYD HVM
BYD landed in third place among our installers choices. One of the advantages of BYD is its partnership with Fronius, who produce some of the best inverters available.
BYD batteries are designed to DC-couple with Fronius’ latest Gen24 inverter range.
SolarQuotes reviewers have rated BYD batteries an impressive 4.9 out of 5 stars.
For a BYD HVM (13.8 kWh), the rebate should reduce the cost by roughly $4,608.
That whittles the $10,600 estimated retail cost down to $5,992, not including installation.
Next Steps
So there you have it: how much the battery rebate could save you on the brands most highly recommended by our installers — use the calculator yourself for your preferred battery brand and size if it wasn’t mentioned here, and see the estimated price for those batteries before applying the rebate in our comparison table.
That link to the table also takes you to a comprehensive guide on all the aspects to consider when deciding whether to purchase a battery: cost is only one factor, and just because getting a battery is now cheaper doesn’t necessarily mean it is right for your circumstances.

For cuatomers in NSW can this be combined with the NSW state battery rebate? Be good if the article could also show the impact of state based incentives.
I was very easily convinced to buy solar panels simply because those panels paid the loan! The savings were so large!
The 10 KW Sungrow battery we had installed was done only so I pay a green loan and not an energy retailer, it costs us money, and honestly, we would need another 30-40 KW’s to make it work for us. It isn’t going to happen soon, rebate or not.
I’ve done the sums so many times to justify (to the wife) getting a second Powerwall. But unless we’re looking to sell into the wholesale market through Amber, it’s not really a goer, even with the rebate. And even then it’d be a marginal thing.
One Powerwall does everything we need, we rarely need to draw from the grid and now with super-cheap and even free retail rates at certain times of day, I’ve found it preferable to use the existing Powerwall to tap into those, than buy a second one.
It’d be nice if rebate programs rewarded early adopters for once, with retrospective claims!
