What happened
A fire broke out on the roof of a home in Emerald in central Queensland. An electrician confirmed that the fire began in faulty DC isolators on a rooftop solar system installed about a decade earlier. People at the home used a ladder and a fire extinguisher to put out the blaze and saved the house. The source does not say whether anyone was injured. It notes that, since 2018, breather valves have been used to ventilate isolator switches and reduce overheating, and that isolator fires can occur if the devices are exposed to the weather.
Contributing factors
An electrician attributed the fire to faulty DC isolators. The householder said she had not known that the older system should have had regular maintenance checks. The report does not say whether water ingress or weather exposure caused this particular fault.
Lessons learned
- Home owners should arrange annual inspections of rooftop solar systems by accredited installers, with particular attention to isolators and wiring.
- Systems should be checked after major weather events for signs of damage or water ingress, and damaged equipment should not be touched.
- Regular maintenance reduces the chance of electrical fires in solar installations.
