Want a Cheaper Home Battery? Federal rebate now offers 1,259 models to choose from

The huge array of different home battery systems available to consumers through the federal Cheaper Home Batteries rebate has ballooned by nearly 500 since July 2025, as manufacturers compete for a share of Australia’s newly booming market.

According to the Clean Energy Council’s Rooftop Solar and Storage Report covering the second half of 2025, battery systems on the on the CEC approved product list increased from 764 to 1,259 models over the six-month period, marking a nearly 65 per cent jump.

Many of these new home battery models came from brands already established in the Australian market, but the number of new manufacturers to join the approved product list expanded from 110 to 123 over that timeframe, adding 13 new names to the menu. 

The numbers from the CEC reflect the state of flux that has been shaking things up in Australia’s home battery market since federal Labor first announced its plan to introduce subsidise residential energy storage.

As Renew Economy has reported, this has included the rise and rise of China newcomer, Sigenergy, which has gone from company launch, in 2022, to debuting its first batteries in 2023, and leading the Australian market by early 2025.

According to industry analyst SunWiz, Sigenergy held a 25 per cent market share across 2025 after becoming the top brand in March of that year, toppling the long-time market leader Tesla and sending its evergreen Powerwall battery near to the bottom of the top-five list.

The number of inverter models on the CEC has also grown, although at a less frantic pace than batteries. In the second half of 2025, inverter models increased on the approved product list jumped nearly 10 per cent from 1,897 to 1,965, while PV modules increased from 2,596 to 3,195, up 23 per cent.

All told, the CEC says there were 6,419 PV modules, inverters and batteries published on its approved product lists at the end of December 2025 – a 24.5 per cent increase on numbers at June 30, 2025 (5,157 models).

“The CEC recorded sustained high volume of applications for batteries and inverters listings throughout H2 2025, reflecting continued growth in distributed energy uptake and increase market activity associated with the expansion of battery incentive programs,” the report says.

“Battery application volumes remain high across the period with 128 applications received, aligning with the commencement of the Cheaper Home Battery Program.

“Batteries represented 49% of all applications received, followed by inverters and power conversion equipment application (33%) and PV modules (18%). Rejection and withdrawal totalled 62 for the period, driven primarily by battery applications.

“These outcomes reinforce the importance of complete, high-quality submissions and clear supporting evidence at the point of application lodgement,” the CEC says.
