IEC TS 62257-9-4:2016(E) specifies the general requirements for the design and the implementation of a user's installation. It applies to single phase user's electrical installations with maximum power of 500 VA, in decentralized rural electrification systems. It is applicable to installations supplied by an AC microgrid and to installations encompassing their own single-unit AC micropower plant or DC micropower plant. The main technical changes with regard to the previous edition are as follows: changing the voltage range covered by the technical specification to AC nominal voltage below 1 000 V and DC nominal voltage below 1 500 V.
