Photovoltaic power generating systems - EMC requirements and test methods for power conversion equipment
IEC 62920:2017 specifies electromagnetic compatibility (EMC) requirements for DC to AC power conversion equipment (PCE) for use in photovoltaic (PV) power systems. The PCE covered by this document can be grid-interactive or stand-alone. It can be supplied by single or multiple photovoltaic modules grouped in various array configurations, and can be intended for use in conjunction with batteries or other forms of energy storage. This document covers not only PCE connected to a public low voltage AC mains network or other low voltage AC mains installation, but also PCE connected to a medium or high voltage AC network with or without step-down power transformers.

Systèmes de production d'énergie photovoltaïque - Exigences de CEM et méthodes d'essai pour les équipements de conversion de puissance
L'IEC 62920:2017 spécifie les exigences de compatibilité électromagnétique (CEM) pour les équipements de conversion de puissance (PCE) en courant continu et en courant alternatif utilisés dans les systèmes de production photovoltaïque (PV). Le PCE couvert par le présent document peut être couplé au réseau ou autonome. Il peut être alimenté par un ou plusieurs modules photovoltaïques disposés en différents groupes et peut être destiné à être utilisé avec des batteries ou d’autres formes de stockage de l’énergie. Le présent document couvre non seulement les PCE connectés à un réseau public en courant alternatif à basse tension ou à une autre installation secteur en courant alternatif à basse tension, mais aussi les PCE connectés à un réseau en courant alternatif à moyenne ou haute tension avec ou sans transformateur de puissance abaisseur.
Fotonapetostni energetski sistemi - Zahteve EMC in preskusne metode za opremo močnostnih pretvornikov
IEC 62920:2017 določa zahteve EMC za elektromagnetno združljivost za opremo močnostnih pretvornikov enosmerne v izmenično napetost za uporabo v fotonapetostnih energetskih sistemih. Močnostni pretvorniki, ki jih zajema ta dokument, so lahko mrežno interaktivni ali samostojni. Dobaviti jih je mogoče kot enega ali več fotonapetostnih modulov, združenih v različne konfiguracije, in jih je mogoče uporabiti v povezavi z akumulatorji ali drugimi oblikami shranjevanja energije. Ta dokument ne zajema le močnostnih pretvornikov, ki so povezani z javnim nizkonapetostnim omrežjem ali drugo nizkonapetostno omrežno napeljavo, temveč tudi močnostne pretvornike, ki so priključeni na omrežje srednje ali visoke izmenične napetosti s pretvorniki, ki omogočajo transformacijo navzdol, ali brez njih.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62920 has been prepared by IEC technical committee 82: Solar
photovoltaic energy systems.
The text of this International Standard is based on the following documents:

INTRODUCTION
Background
Power conversion equipment (PCE) is indispensable for solar photovoltaic power energy
systems in order to convert the DC electric power energy generated by solar photovoltaic
panels into AC electric power, and to feed the AC power energy into the AC mains network or
loads.
In recent years, standardization of EMC requirements for PCE has become more active. For
example, CISPR/B has been considering the limits and measurement method for conducted
disturbances at DC power ports of grid connected power converters since 2008. These
proposed limits and measurement methods form the basis of the instructions for
supplementing CISPR 11 in order to cover the set of EMC requirements for the PCE applying
to the solar photovoltaic power energy systems. EMC requirements for PCE were added in
CISPR 11 Ed.6.0 which was published in 2015. Some product committees, which consider
products utilizing PCE, have their own product standards on EMC requirements. SC 22G has
developed IEC 61800-3 to define the limits and test methods for power drive systems. SC 22H
has IEC 62040-2 for uninterrupted power supplies, and TC 26 has IEC 60974-10
