From July 2025, going solar just got even better. Thanks to the upcoming Cheaper Home Batteries Program, eligible Australians will be able to save up to 30% off the cost of a home battery system, potentially cutting your out-of-pocket expenses by thousands.
Whether you’re upgrading your existing solar setup or starting fresh, this new federal rebate could make energy independence far more affordable than ever before. And here at Solar Secure, we’re already helping families prepare to take full advantage.
What Is the Cheaper Home Batteries Program?
Announced in the 2024–25 Federal Budget, this landmark initiative is all about boosting battery storage across Australian homes. While we’ve led the world in rooftop solar, battery adoption has lagged, mainly because of high upfront costs.
From 1 July 2025, eligible households will be able to access :
- Around $372 per kWh off your battery, which equals ~$3,720 off a typical 10kWh battery
- Open eligibility – there’s no income test, and both new and existing solar system owners can apply
- Stackable rebates – combine it with your state’s existing rebates and interest-free loans
And there’s no cap. If you’re eligible, you’ll get the discount - it’s that simple.
1. Neovolt Battery
Understanding Neovolt: The Company Behind the Battery
Before diving into the specifics of the battery, it's essential to understand the company behind it. Neovolt is a relatively new player in the Australian energy storage market, but they have quickly gained attention for their focus on providing cost-effective and reliable lithium-ion battery solutions. This Neovolt battery review will consider their reputation and track record where available.
What Sets Them Apart?
- Lithium-Ion Technology : Utilizing advanced lithium-ion chemistry, Neovolt batteries offer high energy density, longer lifespans, and better performance compared to traditional lead-acid batteries.
- Scalability : Many Neovolt models are modular, allowing you to increase your storage capacity as your energy needs grow. This flexibility is a significant advantage noted in many Neovolt battery reviews.
- Integrated Battery Management System (BMS) : The built-in BMS ensures safe and efficient operation by monitoring voltage, current, and temperature, protecting the battery from overcharging or discharging.
- Ease of Installation : Designed with installers in mind, Neovolt batteries often feature a relatively straightforward installation process, potentially reducing installation costs.
- Competitive Pricing : One of the frequently mentioned aspects in any Neovolt battery review is their competitive pricing, making solar storage more accessible to a wider range of homeowners.
How Well Do Neovolt Batteries Perform?
A critical aspect of any Neovolt battery review is its performance. Neovolt batteries generally offer good round-trip efficiency, meaning a high percentage of the stored energy can be retrieved. While specific efficiency figures vary between models, they typically fall within the industry standard for lithium-ion batteries.
Lifespan and Warranty
The lifespan and warranty of a solar battery are crucial factors. Neovolt batteries typically come with a competitive warranty period, often around 10 years, which aligns with industry standards for lithium-ion batteries. The number of charge/discharges cycles a battery can handle over its lifetime is also an important consideration discussed in detailed Neovolt battery reviews.
Safety Features of Neovolt Batteries
Safety is paramount when it comes to energy storage. Neovolt batteries incorporate multiple safety features, including the Battery Management System (BMS), to protect against overcharging, over-discharging, and thermal runaway. This is a crucial aspect often highlighted in positive Neovolt battery reviews.
Is This the Best Solar Storage for You?
