Changes to solar installation requirements
Amendents to AS/NZS 5033:2014 Installation and safety requirements for photovoltaic (PV) arrays came into effect on 29 June 2019.
This amendment places additional obligations to protect DC isolators (installed at the PV array) from environmental effects such as sun and rain. The change was introduced as a result of investigations into failures which led to a fire. Installers doing solar installations need to become familiar with the changes.
