Have your say on new standard for installing battery energy storage systems

Standards Australia have released a new draft standard for installation of battery energy systems (BESS), DR AS/NZS 5139:2017 Electrical installations—Safety of battery systems for use with power conversion equipment.

The draft standard covers general installation and safety requirements for BESS, where the battery system is installed and connected with power conversion equipment to supply electric power to other parts of an electrical installation. The draft standard applies to on-site built BESS units and pre-assembled integrated BESS units.

This standard outlines the hazards that are associated with BESS and specifies installation methods that eliminate or minimize these hazards.

There are potentially serious safety risks to the installer or the homeowner if these battery systems are incorrectly installed. Having a robust standard for installers will help reduce these risks.

This is a draft document that will be amended by the Standards Australia committee based on feedback from industry and other stakeholders. Feedback is needed to ensure the final standard is able to be understood, applied and adequately address the risks identified.

There's nothing like getting back for getting better

Workers who get back to safe work as soon as possible recover more quickly than those who wait until they are fully recovered.
