In August 2024, Standards Australia released a new version of AS/NZS 4777.1 Grid connection of energy systems via inverters Part 1: Installation requirements (AS/NZS 4777.1:2024).
The update saw a range of changes to improve the safety of electrical installations and support the security of the electricity supply network taking into account standardised improvements to inverter technology since the last installation standard was released.
These changes will support the continued increase of solar Photovoltaic (PV), batteries and electric vehicles.
From 23 February 2025 it will be mandatory for all inverters connected at low voltage to the distribution network to be compliant to AS/NZS 4777.2:2020 and installed in compliance with AS/NZS 4777.1:2024.
In addition to AS/NZS 4777.1:2024, inverters will also need to meet any relevant DNSP network standards.
