Grid connected photovoltaic systems - Minimum requirements for system documentation, commissioning tests and inspection
IEC 62446:2009 defines the minimal information and documentation required to be handed over to a customer following the installation of a grid connected PV system. Also describes the minimum commissioning tests, inspection criteria and documentation expected to verify the safe installation and correct operation of the system. Is written for grid connected PV systems only.

Systèmes photovoltaïques connectés au réseau électrique – Exigences minimales pour la documentation du système, les essais de mise en service et l’examen
La CEI 62446:2009 définit les informations et la documentation minimales exigées devant être remises à un client à la suite de l'installation d'un système PV connecté au réseau. Décrit également les exigences minimales des essais de mise en service, des critères d'examen et de la documentation prévus pour vérifier l'installation en toute sécurité et le fonctionnement correct du système. Concerne uniquement les systèmes PV connectés au réseau.
Fotonapetostni sistemi, priključeni na omrežje - Minimalne zahteve za sistemsko dokumentacijo, prevzemne preskuse in nadzor (IEC 62446:2009)
Ta mednarodni standard določa minimalne informacije in dokumentacijo, ki se mora predati kupcu po vgradnji fotonapetostnega sistema, priključenega na omrežje. Ta standard opisuje tudi minimalne prevzemne preskuse, nadzorna merila in dokumentacijo za preverjanje varne vgradnje in pravilnega delovanja sistema. Dokument se lahko uporablja tudi za redno ponovno preskušanje. Ta standard je napisan le za fotonapetostne sisteme, priključene na omrežje, in ne za sisteme z moduli za izmenični tok, ali sisteme, ki uporabljajo hranilnike energije (npr. baterije) ali hibridne sisteme. Ta standard se uporablja za sistemske načrtovalce in monterje fotonapetostnih sončnih sistemov, priključenih na omrežje, kot predloga za zagotavljanje učinkovite dokumentacije za kupce. S podrobnim navajanjem pričakovanih prevzemnih preskusov in nadzornih meril se uporablja tudi kot pomoč pri preverjanju/nadzoru fotonapetostnega sistema, priključenega na omrežje, po vgradnji in za nadaljnji ponovni nadzor, vzdrževanje ali spreminjanje.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 individ
