While Australia does not have a single national register for home battery safety, it operates a comprehensive, multi-layered framework to ensure systems are safe. This framework is built on three key pillars: a list of approved products that meet stringent safety standards, a national accreditation system for installers, and mandatory installation standards. To be eligible for government rebates, your battery must be on the Clean Energy Council's approved product list and installed by a professional accredited by Solar Accreditation Australia.
Is there a national register or certification system for home battery safety?
Navigating the world of home energy storage can feel complex, but when it comes to safety, Australia has a robust system in place to protect homeowners. While there isn’t one single database you can check, safety is managed through a combination of product certification, installer accreditation, and strict installation standards that work together to create a secure environment for your home battery system.
The three pillars of battery safety in Australia
Think of Australia’s battery safety system as a three-legged stool. Each leg is essential for providing a stable and safe foundation for your investment. If one is missing, the entire system can become unstable.
The three pillars are:
- Approved Products: Only batteries that have been tested and certified to meet high safety and quality standards can be sold and installed.
- Accredited Installers: The system must be designed and installed by a qualified and accredited professional.
- Mandatory Standards: The installation itself must comply with strict Australian Standards for electrical safety.
Pillar 1: The list of approved battery products
There is no mandatory national register of every battery installed, but there is a crucial list of products that are approved for installation. To ensure a battery is safe and eligible for government incentives, like the federal Cheaper Home Batteries Program starting in July 2025, it must be on the Clean Energy Council’s (CEC) list of approved battery systems.
This list is a critical tool for consumers. It confirms that the battery models on it have been independently tested and verified to meet specific Australian and international safety standards. These standards are designed to prevent common risks associated with battery systems. The CEC’s Battery Assurance Program is a key part of this, providing independent information on the safety and quality of lithium-based batteries.
When considering a battery, a key question for your retailer should always be: “Is this exact model on the Clean Energy Council’s approved battery list?” You can also view the list yourself on the CEC website.
Pillar 2: Accredited installers for safe installation
Even the best battery can be unsafe if installed incorrectly. This is why the second pillar—installer accreditation—is so important. In Australia, individuals who design and install grid-connected battery systems must be accredited by Solar Accreditation Australia (SAA).
This accreditation ensures the installer has the specific training and technical knowledge required to install battery systems safely and according to all relevant standards. Using an SAA-accredited installer is a mandatory requirement for accessing government rebates under the Small-scale Renewable Energy Scheme (SRES).
Before hiring a professional, you should ask for their SAA accreditation number and verify their status. This ensures they are up-to-date with the latest safety requirements and best practices.
Pillar 3: The safety standard: AS/NZS 5139
The third pillar is the rulebook for installation: Australian/New Zealand Standard 5139 (AS/NZS 5139). This standard sets out detailed requirements for the safe installation of battery energy storage systems (BESS). It covers crucial safety aspects such as:
- Where a battery can and cannot be located within a property.
- Requirements for ventilation and protection from heat sources.
- Necessary signage and labelling for safety and emergencies.
- Specific electrical wiring and protection requirements.
Compliance with AS/NZS 5139 is not optional; it is a mandatory requirement for all grid-connected battery installations. After the installation is complete, the accredited installer must provide you with a Certificate of Electrical Compliance (or its equivalent in your state). This document is your proof that the system has been installed in accordance with these vital safety standards and is necessary for warranty and insurance purposes.
How government rebates reinforce the safety framework
Government incentive programs play a significant role in upholding these safety standards. The upcoming federal Cheaper Home Batteries Program, which began on 1 July 2025, ties its rebates directly to this safety framework. To be eligible for the discount, homeowners and small businesses must use a battery from the CEC-approved list and have it installed by an SAA-accredited professional. This creates a powerful incentive for the entire industry to adhere to the highest safety protocols.
What does this mean for you as a homeowner?
While you don’t need to be an expert on standards and regulations, understanding this safety framework empowers you to ask the right questions and make informed decisions.
When planning for a home battery, your checklist should include:
- Verify the Product: Confirm that your chosen battery and inverter are on the Clean Energy Council’s approved product lists.
- Verify the Installer: Ensure your installer is an individual accredited by Solar Accreditation Australia (SAA) for battery installations.
- Request the Paperwork: Upon completion, make sure you receive a Certificate of Electrical Compliance for your records.
By ensuring these three pillars are firmly in place, you can be confident that your home battery system is not only a smart investment in your energy future but also a safe one.
