AS/NZS 4777.1, Grid Connection of Energy Systems via Inverters – Part 1: Installation Requirements was published in August 2024. The new version, AS/NZS 4777.1:2024, contains a series of changes
ESO awarded ten contracts to four providers worth a total of £323 million and procured 11.55 GVA of SCL and 6.75 GVAs of inertia. This will be provided by a combination of GFM BESS and SynCons.
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
Grid-forming BESS Connections This fact sheet contains information relevant to parties seeking to connect battery energy storage systems (BESS) with grid-forming inverter capabilities

A grid connected inverter is a vital part of a grid-connect solar electricity system as it converts the DC current generated by solar panels to the 230 volt AC current needed to run household appliances.
As the renewable energy landscape continues to evolve, the 2024 revision of AS/NZS 4777.1:2024, Grid connection of energy systems via inverters—Installation requirements, marks a
These supply types also assist in identifying when inverters are considered grid connected and are required to meet DNSP technical requirements, inverter compliance requirements and need approval
Stakeholders involved in specifying, installing, or maintaining grid-connected inverters should carefully review these changes and ensure full compliance with AS/NZS 4777.1:2024, AS/NZS 4777.2, and
This document deals with connection requirements of grid-following inverters connected to electricity transmission systems, which are characterised as being meshed networks.
