Learn how Australia's Federal Government battery incentive can reduce the upfront cost of eligible battery installations. Understand eligibility, STC discounts, battery sizing and what to consider before investing in home energy storage.
A professionally designed battery system helps you store excess solar energy, reduce grid dependence and maximise your renewable energy investment.
The Cheaper Home Batteries Program is an Australian Government initiative designed to reduce the upfront cost of eligible residential and small-business battery storage systems.
The incentive is delivered through Small-scale Technology Certificates (STCs). Instead of customers applying for a separate rebate after installation, the certificate value is generally assigned to an approved retailer or installer and included as an upfront reduction on the system quotation.
Eligible batteries can receive upfront financial support, making energy storage more affordable for Australian households.
Store excess solar generation during the day and use it when electricity demand and prices are higher.
A correctly designed battery system can help reduce reliance on the electricity grid and improve household energy management.
Battery incentives are calculated based on eligible usable battery capacity. Larger batteries may receive different certificate factors depending on the capacity range.
| Battery Capacity | STC Factor | Support Level | Explanation |
|---|---|---|---|
| First 14 kWh | 100% | Maximum Support | Full certificate value applies within this capacity range. |
| 14 kWh - 28 kWh | 60% | Reduced Support | Additional capacity receives a lower certificate factor. |
| 28 kWh - 50 kWh | 15% | Limited Support | Only a smaller certificate value applies. |
| Above 50 kWh | 0% | No STCs | Capacity above this limit does not receive STC support. |
The incentive calculation is based on eligible usable battery capacity, not simply the advertised battery size.
Battery size should match household energy usage, solar production, tariffs and backup requirements.
Correct installation, approved products and compliance requirements are essential for eligibility.
Not necessarily. The commonly advertised "around 30%" reduction is an estimate for a typical eligible battery system. The actual discount varies depending on battery capacity, STC value, installation timing, system eligibility and market conditions.
The Cheaper Home Batteries Program is designed to support eligible Australian households and small businesses installing approved battery storage systems.
A larger battery is not always better. The ideal capacity depends on your daily electricity usage and solar generation.
Your existing inverter, switchboard and solar system must be compatible with the proposed battery solution.
Not every battery provides blackout protection. Backup functionality requires compatible equipment and installation.
Battery retrofits can work with existing solar systems, but compatibility checks are required.
Consider manufacturer warranty, installer support and long-term service availability.
Switchboard upgrades, additional cabling, metering and compliance work may be required.
A quality battery installation starts with understanding your energy habits. Solar generation, household consumption, electricity tariffs, future EV charging and backup requirements should all be considered before selecting a system.
Solar Link Australia can assess your existing solar system, electricity usage, switchboard requirements and energy goals to recommend a battery solution designed around your home.
