What You Need to Know About DC Isolator Safety


To mitigate the risks associated with incorrect DC isolator installation, it is essential to adhere to best practices and safety guidelines:

Qualified professionals: Employ qualified and licensed electrical professionals who have experience in PV solar system installations. Ensure that they are well-trained and knowledgeable about DC isolator installation requirements.

Compliance with standards: Ensure all installations comply with relevant industry standards and codes, such as the Australian Standards for Solar PV Systems (AS/NZS 3000:2018 Amendments 1, 2 & 3, AS/NZS 5033:2021, Clean Energy Council (CEC) guidelines and the manufacturer’s instructions.).

Regular inspections and maintenance: Don’t “Set and Forget,” Solar PV system owners need to have a routine maintenance plan as indicated in the owner’s manual for someone to clean, examine, and test their solar installation regularly to guarantee they are getting the most out of the system.

Documentation: Keep thorough records of the installation process, maintenance activities, and compliance documentation. This documentation will be crucial for audits and regulatory compliance. 

Solar PV installers are reminded that all installations in the Northern Territory’s cyclone-prone areas must have a building permit. This requirement has no exceptions.

Training and education: Continuously educate and train workers and contractors involved in PV solar system installations on the proper procedures for DC isolator installation and safety protocols.
