AS 4777.2:2005 Grid Connection of Energy Systems via Inverters - Inverter Requirements is a standard that specifies the requirements for inverters used for the injection of electric power into the electricity distribution network. The standard covers inverters with ratings up to 10 kVA for single-phase units or up to 30 kVA for three-phase units.

While this standard specifically focuses on inverters for renewable energy systems with a DC power source, such as photovoltaic arrays, it can also be adapted for systems using variable AC power sources like wind turbines or micro-hydro systems with appropriate modifications to the tests.

Notably, this standard does not include electromagnetic compatibility (EMC) requirements, as these are mandated by the Australian Communications Authority (ACA). Users are advised to refer to the ACA's document on electromagnetic compatibility for guidance on meeting these requirements.

It is important to note that this standard is applicable to smaller-scale energy systems and does not cover larger systems. However, the principles outlined in AS 4777.2:2005 can serve as a basis for designing such larger systems.
