UNE-EN IEC 62909-1:2025

This part of IEC 62909 specifies general and safety aspects of bi-directional grid-connected power converters (GCPC), consisting of a grid-side inverter with two or more types of DC power ports on the application side with system voltages not exceeding 1 000 V AC or 1 500 V DC.This document may also be used for the special case of a multiple DC power port GCPC is used in an application requiring only one DC power port.This document considers general aspects such as terminology, specifications, performance, system architecture, as well as safety requirements.This document does not cover:- uninterruptible power supply (UPS) systems, which fall under the scope of IEC 62040 (all parts),- power conversion equipments for use in photovoltaic systems, which fall under the scope of IEC 62109 (all parts), or- the single port bidirectional power converters to charge or discharge the batteries located within electric vehicles or in the charging station, which fall under the scope of IEC 61851 (all parts).NOTE 1 the external system (e.g. Energy management system, Utility operations system ) is not defined in this document.NOTE 2 The case power converter sub-system for use in Electrical Energy Storage Systems is currently covered by this document, but in the future this case will be covered by IEC 63285 series.NOTE 3 Annex A provides examples of GCPCs. These examples contain GCPCs covered and not covered by this document.
