Warning issued on fire risk to Solar PV systems
NT WorkSafe has issued a Safety Alert warning of the increased risks of fires if DC isolators are not installed correctly and in line with manufacturers’ guidelines.
Electrical Safety Inspectors have attended eight fires this year that started in the DC isolator of a Solar PV System. Two properties suffered extensive fire damage.
Solar PV installers and electrical contractors are urged to ensure the installation option selected is appropriate for the location of the DC isolator and the ingress protection of the isolator isn’t compromised during installation.
Electrical Safety Inspectors have issued 22 infringement notices this year to Solar PV installers for non-compliant installations.
Information for solar PV system owners
Owners of solar PV systems must ensure that:
- The required building permits are obtained before the installation beings.
- The installer provides an electrical certificate of compliance once the installation has been completed.
- The installer must also provide the systems owner manual, warranty information and emergency shutdown information.
- The installer should demonstrate the start-up and shutdown procedures, including how to safely isolate the system in case of an emergency.
- A scheduled maintenance program is set as outlined in the owner’s manual for someone to regularly clean, inspect and test the solar system.
If there are concerns on the safety of your solar PV system, contact a licensed electrical contractor for assistance and advice. A list of licensed electrical contractors is available on the Electrical Workers and Contractors Licensing Board website.
NT WorkSafe audits
Electrical Safety Inspectors conduct random audits on new Solar PV installations to ensure they have been installed to the required standard.
These audits occur at both commercial and residential properties, and will require Electrical Safety Inspectors to enter your property to exam your Solar PV systems. All inspectors carry photo identification.
