Provides performance requirements and tests for inverters.

This Standard specifies performance requirements for low voltage a.c. output inverters, both single-phase and three-phase, intended for use in stand-alone power systems with batteries. It applies to inverters with - (a) ratings up to 10 kVA for single-phase units, or up to 30 kVA for three-phase units;(b) a nominal a.c. voltage equivalent to the nominal supply voltage 230 V (single-phase) or 400 V (three-phase);(c) a nominal a.c. frequency of 50 Hz; and(d) nominal d.c. voltages up to 300 V between positive and negative or (300 V d.c. with respect to earth and connected to a battery.NOTES:1 Although this Standard does not apply to larger systems or systems of different nominal voltage or nominal frequency, similar principles apply to such equipment.2 This Standard does not specify EMC requirements, which for Australia are covered by the requirements of the Radiocommunications Act 1992 and for New Zealand by the Radiocommunications Regulations 2001. For further guidance on Australian requirements, see the Australian Communications and Media Authority’s document Electromagnetic Compatibility - Information for suppliers of electrical and electronic products in Australia and New Zealand.
