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.

IEC TS 62257‑100 has been prepared by IEC technical committee 82: Solar photovoltaic energy systems. It was developed in cooperation with other IEC technical committees and subcommittees dealing with renewable energies and related matters, namely IEC technical committee 21: Secondary cells and batteries, subcommittee 21A: Secondary cells and batteries containing alkaline or other non-acid electrolytes, IEC technical committee 64: Electrical installations and protection against electric shock, IEC technical committee 88: Wind energy generation systems. It is a Technical Specification.

This first edition of IEC TS 62257‑100 cancels and replaces the third edition of IEC TS 62257‑1 issued in 2015. It constitutes a major technical revision. This new edition of the introductory document transitions the entire series to a 3-digit numbering scheme. The overall numbering scheme is presented, including planned topics and sub-topics, to assist in organizing future documents and to differentiate the new documents from those under the former scheme. This major re-organization and update of the series was determined by JWG1 to be necessary to accommodate major advances within this subject area.

The main technical changes with regard to the previous edition’s introductory document, IEC TS 62257‑1, are as follows:

– describe the major updates for the IEC 62257 series;
– new simplified title for the series “Renewable energy off-grid systems”, which will precede individual part numbers;
– provide an introduction to the entire series, including the updated organization and planned content of the IEC 62257 series;
– add example user case studies to assist various users in selecting relevant parts within the series;
– removal of content replicated in other documents and relocation of some information to other planned documents in this series;
– addition of general information on access to electricity;
– additional information on managing a renewable energy off-grid project including tendering;
– removal of an annex containing definitions, originally intended to cover all documents in the series; future documents published under this new scheme will contain definitions for individual documents within that document itself.

This technical specification should be used in conjunction with the other documents of the IEC 62257 series, as relevant.

The text of this Technical Specification is based on the following documents:

Draft	Report on voting
82/2028/DTS	82/2066/RVDTS

Full information on the voting for its approval can be found in the report on voting indicated in the above table.

The language used for the development of this Technical Specification is English.

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are described in greater detail at www.iec.ch/publications.

A list of all parts in the IEC 62257 series, published under the general title Renewable energy off-grid systems, can be found on the IEC website.

Future standards in this series will carry the new general title and three-digit numbering. Titles and numbers of existing standards in this series will be updated at the time of their next edition.

The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under webstore.iec.ch in the data related to the specific document. At this date, the document will be

• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
