COMMISSIONELECTRICAL INSTALLATIONS OF BUILDINGSPart 7-712:Requirements for special installations or locationsSolar photovoltaic(PV)power supply systemsFOREWORD1)The IEC(International Electrotechnical Commission)is a worldwide organization for standardization comprisingall national electrotechnical committees(IEC National Committees).The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields.Tothis end and in addition to other activities,the IEC publishes International Standards.Their preparation isentrusted to technical committees;any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work.International,governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation.The IEc collaborates closely with the InternationalOrganization for Standardization(ISO)in accordance with conditions determined by agreement between thetwo organizations.2)The formal decisions or agreements of the IEC on technical matters express,as nearly as possible,aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards,technical specifications,technical reports or guides and they are accepted by the NationalCommittees in that sense.4)In order to promote international unification,IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards.Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights.The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60364-7-712 has been prepared by IEC technical committee 64:Electrical installations and protection against electric shock.The text of this standard is based on the following documents:FDISReport on voting64/1229/FDIS64/1244/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives,Part 3.The committee has decided that the contents of this publication will remain unchanged until 2006.At this date,the publication will bereconfirmed;withdrawn;replaced by a revised edition,oramended.60364-7-7121EC:2002-7-INTRODUCTIONThe requirements of this part of IEC 60364 supplement,modify or replace certain of thegeneral requirements contained in parts 1 to 6 of IEC 60364.The clause numbering appearing after 712 refers to the corresponding parts or clauses ofIEC 60364,parts 1 to 6.Numbering of clauses does not,therefore,necessarily followsequentially.Numbering of figures and tables takes the number of this part followed by asequential number.The absence of reference to a part or a clause means that the general requirementscontained in parts 1 to 6 of IEC 60364 are applicable.60364-7-7121EC:2002-9ELECTRICAL INSTALLATIONS OF BUILDINGSPart 7-712:Requirements for special installations or locations-Solar photovoltaic(PV)power supply systems712Solar photovoltaic(PV)power supply systemsNOTE The abbreviation PVis used for solar photovoltaic712.1 ScopeThe particular requirements of this part of IEC 60364 apply to the electrical installations of PVpower supply systems including systems with AC modules.NOTE 1 Standards for PV equipment are being prepared by TC 82.NOTE 2 Requirements for PV power supply systems which are intended for stand-alone operation are underconsideration.712.2 Normative referencesThe following referenced documents are indispensable for the application of this document.For dated references,only the edition cited applies.For undated references,the latest editionof the referenced document(including any amendments)applies.IEC 60050(826):1982,International Electrotechnical Vocabulary(IEV)-Chapter 826:Electrical installations of buildingsIEC 60439-1,Low-voltage switchgear and controlgear assemblies-Part 1:Type-tested andpartially type-tested assembliesIEC/TR 60755,General requirements for residual current operated protective devicesAmendment 2(1992)IEC 60904-3,Photovoltaic
