Home-owners with solar panels are being asked to check if they have LG branded batteries installed in their systems after the company issued an urgent safety recall.
The recall includes 13 battery models at risk of overheating, catching fire and causing damage to property, serious injury or death.
The defective batteries could be installed in LG branded solar systems or non-LG systems such as SolaX Power Station, Opal Storage and Eguana Evolve.
NSW Fair Trading Commissioner Natasha Mann said the defective batteries had been sold by several companies across Australia since 2017.
"If you have a solar storage system installed, you may have one of these potentially dangerous products and not know it," she said.
"Please take a minute to inspect the batteries as soon as possible (and) if you are affected by the recall, don't panic."
If people find they have a product on the recall list they should immediately switch the battery off and contact LG Energy Solution to organise a remote or on-site visit.
Batteries can be replaced free of charge or customers may be able to ask for a refund.
LG will also compensate customers if their power bill increases while their battery is shut down and a new model installed.
