EcoFlow

As energy costs continue to rise, more homeowners face the challenge of keeping their electricity bills under control while ensuring their home remains powered during outages. Many people struggle with high utility costs, unpredictable blackouts, and the limitations of traditional energy sources. The federal government’s “Cheaper Home Batteries Program” offers a practical solution. By joining this program, homeowners can access government battery rebates and gradually build a reliable home backup battery setup. This approach helps families reduce expenses, gain energy independence, and protect their homes from unexpected power outages. In this article, we will explain the program in detail, including eligibility requirements, how to apply, and tips for choosing the best battery for your home, enabling you to make smarter decisions.

What is the Cheaper Home Batteries Program?

The Cheaper Home Batteries Program is an initiative launched by the Australian federal government on July 1, 2025. The program offers approximately 30% battery rebates on the upfront cost of solar batteries. It is a direct expansion of the successful Small-scale Renewable Energy Scheme (SRES) and operates through the Small-scale Technology Certificate (STC) mechanism. Homeowners do not need to wait for a tax refund, as accredited installers apply the rebate directly to the purchase quote at the time of installation.

The program supports battery systems with capacities ranging from 5 kWh to 100 kWh and is available across Australia. It is open to households, small businesses, and community organisations, with no income restrictions. To qualify, the battery must be used in conjunction with a new or existing rooftop solar system.

Changes to the Cheaper Home Batteries Program After 2026

Starting in 2026, the Cheaper Home Batteries Program will undergo important updates. On December 13, 2025, the Australian government announced an increase in the program’s budget from the initially planned AUD 2.3 billion to AUD 7.2 billion over the next four years. It is estimated that by 2030, more than 2 million Australians will install home energy storage batteries, adding around 40 GWh of storage capacity.

These changes also come with adjustments to the program itself, ensuring that the rebates continue to apply to small, medium, and large battery systems. The updated rules take effect on May 1, 2026, with the following specific adjustments.

STC Factor Adjustments

The STC factor determines how many certificates can be generated per kilowatt-hour of battery capacity, which in turn affects the rebate amount a homeowner receives. The discount you are eligible for is based on the STC factor on the day your battery is installed.

Starting from May 1, 2026, the STC factor will decrease every six months. The reduction rate will be faster than before, meaning future installations may receive slightly lower rebates over time. Homeowners planning to install a battery system are encouraged to consider this schedule when deciding on installation timing, as acting sooner can help maximise the available rebate.

Adjusted Support Based on Battery Size

The program will continue to support battery installations with capacities up to 100 kWh. However, starting from May 1, 2026, the level of battery rebates will be adjusted. The discount calculations have been adjusted to align with declining battery costs, with the aim of maintaining around 30% discount for a range of battery systems at each capacity level.

The STC factor now decreases based on the installed battery capacity:

  • From 0 kWh up to 14 kWh (inclusive): 100% STC factor.

  • Over 14 kWh and up to 28 kWh (inclusive): 60% STC factor per kWh.

  • Over 28 kWh and up to 50 kWh (inclusive): 15% STC factor per kWh.

This adjustment ensures that the rebate proportion remains consistent for small, medium, and large battery systems, allowing homeowners to plan their installations more effectively according to their energy needs.

Eligibility for the Cheaper Home Batteries Program

To participate in the Cheaper Home Batteries Program, homeowners must meet certain eligibility requirements. Understanding these criteria ensures a smooth application process and helps plan the battery installation effectively.

  • The battery system must have a nominal capacity between 5 kWh and 100 kWh.

  • It must be installed on or after 1 July 2025 (or certificated on that date) to qualify.

  • The battery must be installed alongside a new or existing solar PV system on the same premises. Batteries installed without solar are not eligible.

  • The system must be installed by an installer accredited by the Solar Accredited Authority (SAA) in Australia, and the battery/inverter must be listed on the CEC-approved product list.

  • For grid-connected systems, the inverter must have Virtual Power Plant (VPP) capability, though participation in a VPP is not mandatory.

  • For off-grid properties, some rules differ. For example, VPP functionality may not be required if the grid connection is very remote or uneconomical.

  • Only one battery system per meter (NMI) is eligible. If you upgrade or increase capacity, the system must not have previously received a rebate, and the total capacity must remain within the allowed range.

How to Claim the Cheaper Home Batteries Program?

  1. Check Eligibility

Before installation, confirm that your battery system is compatible with the program requirements, including pairing with a rooftop solar PV system and meeting technical installation standards.

  1. Choose an Accredited Installer

Select an installer accredited by the SAA. These installers are familiar with the rebate process and know how to handle the necessary paperwork correctly.
