Safety Must Come First in Consideration of Plug-In Solar and Battery Systems

NECA WA is urging a cautious and considered approach to the proposed introduction of plug-in solar and battery systems, warning that significant technical, safety and regulatory issues must be resolved before the technology is approved for widespread use in Western Australia.

The Western Australian Government is examining the potential introduction of plug-in solar and battery systems that would allow small-scale energy generation and storage devices to connect to household electrical installations through a standard power outlet.

While the proposal aims to expand access to renewable energy technologies for households, renters and apartment dwellers, the National Electrical and Communications Association (NECA) says the technology introduces complex electrical safety considerations that differ significantly from traditional rooftop solar and battery systems.

Recent public discussion has highlighted concerns that plug-in systems may create risks if introduced without appropriate standards, testing, installation requirements and consumer safeguards. Concerns include the potential for electrical overload, fire risks, impacts on household wiring, and challenges in ensuring safe installation and ongoing operation.

NECA WA Executive Director Kelly Dewar-Matusik said governments, regulators and industry must work collaboratively to ensure any future framework places safety at its centre.

“NECA is aware of a number of significant technical, regulatory and safety issues associated with plug-in solar and battery systems that remain to be resolved.”

“These technologies should not be viewed as a simple extension of existing rooftop solar or household batteries. They introduce electricity into a home’s electrical installation in a different way, and that requires careful consideration of the potential risks and appropriate safeguards.”

“Our view is that these issues need to be worked through methodically before any decision is made about whether widespread deployment can occur in Australia.”

“While we support innovation and greater consumer access to renewable energy technologies, any pathway forward must maintain the high electrical safety standards Australians rightly expect.”

“NECA looks forward to working with the Western Australian and Australian Governments as we work through these issues.”
