Battery Location Restrictions from AS/NZS 3000:2018

Battery Booster Inspectorate Program

The installation of Battery Energy Storage Systems (BESS) is governed by stringent safety standards as outlined in AS/NZS 5139:2019, specifically in sections 4, 5, and 6. These sections impose explicit restrictions on permissible installation locations to mitigate safety risks. In addition to the provisions specified within AS/NZS 5139:2019, compliance with AS/NZS 3000:2018 is also mandatory as it imposes additional location requirements for avoiding hazardous installations.

Among other important requirements, AS/NZS 3000:2018 provides guidelines for electrical installations in proximity to various gas appliances, as detailed in section 4.18. Notably, this standard includes specific exclusion zones to prevent hazards associated with gas cylinders and gas relief vent terminals. As a faulty battery may produce electrical sparks or excessive heat, it is considered an ignition source and is therefore subject to the location restrictions of ignition sources set out in AS/NZS 3000:2018 section 4.18, concerning gas cylinders.

The following points summarise key restrictions and requirements:

  1. AS/NZS 5139:2019 Compliance: Sections 4, 5, and 6 of AS/NZS 5139:2019 detail prohibitive locations for BESS installations to ensure safety. Installers must adhere to these sections to avoid placing BESS in areas that could pose significant risks.
  2. Hazardous Locations per AS/NZS 3000:2018: BESS installations must also comply with AS/NZS 3000:2018, which identifies hazardous locations, including those near gas appliances. Section 4.18 is particularly relevant for ensuring the safety of electrical installations in these areas.
  3. Exclusion Zones for Gas Cylinders: Figure 4.18 of AS/NZS 3000:2018 specifies exclusion zones for electrical appliances near gas cylinders. BESS installations are an ignition source and must avoid these zones to prevent any potential interaction between electrical systems and gas cylinders that could lead to hazardous conditions.
  4. Exclusion Zones for Gas Relief Vent Terminals: Figure 4.19 of AS/NZS 3000:2018 outlines exclusion zones for electrical appliances near gas relief vent terminals. Similar to the guidelines for gas cylinders, BESS installations must be placed outside these exclusion zones to maintain safety and compliance.

The installation of BESS must strictly adhere to the location restrictions set forth in AS/NZS 5139:2019, with additional consideration given to hazardous locations as identified in AS/NZS 3000:2018. By following these comprehensive standards, installers can ensure the safe and compliant placement of BESS, thereby mitigating risks associated with hazardous environments.

The following excerpts from AS/NZS 3000:2018 help illustrate the hazardous areas and exclusion zones for gas cylinders in proximity to ignition sources.

Agents And Installers

What are the inspectors looking for?

The inspectors are checking installations for safety, compliance, and industry best practices. The main goals of the inspections are to ensure that systems are safe and to uplift the industry by promoting best practices systems.  

The Battery Booster Program Installer Guide lays out the main standard clauses and best practices that the inspectors will be checking for. Access the Installer Guide here: 

How long after the installation will the inspection happen?

The inspection period for the battery booster program is expected to run from May 2024 until mid-2025. Reports with the inspection outcome will be sent to the installer around a month after the inspection is conducted. 

What do I do once I receive an inspection report?

The inspection report will outline all the items that require rectification. Installers under the Battery Booster program are required to return to site and rectify any issues found with the system. The installer then must email GSES with photographic evidence of the rectifications done. GSES will also accept documentation that justifies installation practices in certain cases. 

I disagree with the inspection outcome, what can I do?

Please reply to our email with justification on your installation methods. We recommend attaching standard clauses, manufacturer’s documentation, or industry reputable communication that justifies your decisions. A dispute process is available, all information is in the report sent to you. 

Can I charge the homeowner for rectification

No, it is your responsibility to rectify systems which are not compliant with Australian standards and regulations. You have agreed to this when you signed up to be an accredited installer for the Battery Booster program.
