scope:

This European Standard specifies technical requirements for connection and operation of fixed installed micro-generators and their protection devices, irrespective of the micro-generators primary source of energy, in parallel with public low-voltage distribution networks, where micro-generation refers to equipment rated up to and including 16 A per phase, single or multi phase 230/400 V (line voltage) or multi phase 230 V (phase-to-phase voltage). This European Standard is intended for installation mainly in the domestic market. In some countries this document may be applied to generators with higher ratings used mostly in domestic and small commercial installations. These countries are listed in Annex E. Whenever the scope is extended to equipment rated greater than 16 A per phase additional standards could be applicable. Inform and fit is the recommended procedure for installation of micro-generation except in those countries where legislation precludes this approach e.g. where it is mandatory for the DSO to give prior permission for the connection.
