An Available Superseded Standard is one, which has been made available for a period of time although it has been formally superseded by another Standard. Its availability is maintained where it is referenced in legislation/regulations or in other Standards and its use should be restricted to where so referenced. No responsibility is taken by Intertek Inform as to the ongoing technical validity of such a Standard, the responsibility resting with the referencing authority.

Specifies requirements for inverters with ratings of up to 10kVA for single-phase systems, or 30kVA for three-phase systems, and intended for connection to the low-voltage electricity distribution network (grid).

This Standard specifies the requirements for inverters, with ratings up to 10kVA for single-phase units or up to 30kVA for three-phase units, for the injection of electric power through an electrical installation to the electricity distribution network.Although this Standard does not apply to larger systems, similar principles can be used for the design of such systems.Although this Standard is written on the basis that the renewable energy is from a d.c. source (e.g. photovoltaic array), this Standard may be used for systems where the energy is from a variable a.c. source (e.g. wind turbine or micro-hydro system) by appropriate changes to the tests.This Standard does not include EMC requirements. These are mandated by the Australian Communications Authority (ACA). Users attention is drawn to Australian Communication Authority’s document ‘Electromagnetic Compatibility-Information for suppliers of electrical and electronic products in Australia and New Zealand’ for guidance.
