Enphase Energy, Inc. announced that a growing number of Australian solar installers are now exclusively offering Enphase(R) products, as increased solar safety regulations and compliance standards come into effect across the country. In May 2022, AS/NZS5033:2021, an update to installation and safety requirements for photovoltaic (PV) arrays, came into effect nationwide in Australia. The revised regulations aim to support solar installers in meeting compliance requirements and promoting consumer and electrical contractor safety.

The standard details new compliance measures for direct current (DC) central ("string") inverter-based solar systems, including restrictive cable runs, IEC 62930 compliant DC cable, and high visibility DC voltage and warning signs. In contrast, alternating current (AC) decentralized inverter-based solar systems operating at extra-low voltage, such as installations with Enphase microinverters, are exempt from most new regulations. As a result, some Australian solar installers are exclusively leveraging Enphase technology to help insulate their businesses and customers from electrical risk and future regulatory changes.
