Revision of Installation Requirements for Grid Connection of Energy Systems via Inverters



MasterLogo_pos_colourStandards Australia has recently published AS/NZS 4777.2, Grid connection of energy systems via inverters – Part 2: Inverter requirements. Prepared by Technical Committee EL-042, Renewable Energy Power Supply Systems & Equipment, this standard replaces AS 4777.2-2005 and AS 4777.3-2005.

Much anticipated by industry, it defines minimum performance and safety requirements. Its scope focuses on the design, construction and operation of inverters intended for use in inverter energy systems for the injection of electric power through an electrical installation into the grid.

“The standard provides requirements for inverters so that households and businesses can connect renewable energy systems and battery systems to the grid. With more than 1.4 million inverter energy systems already installed Australia wide and another 130,000 inverter energy systems being added each year this standard is important for all Australians,” stated  Chair of EL-042 Nigel Wilmot.

This standard falls within AS/NZS 4777, which will shortly see the addition of AS/NZS 4777.1, Grid connection of energy systems via inverters – Part 1: Installation requirements. The draft is soon to be released for a second round of public comment with publication anticipated for 2016.
