CSA C22.2 NO. 62109-3:24

CSA Preface This is the first edition of CSA C22.2 No. 62109-3, Safety of power converters for use in photovoltaic power systems — Part 3: Particular requirements for electronic devices in combination with photovoltaic elements , which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 62109-3 (first edition, 2020-07). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. For brevity, this Standard will be referred to as "CSA C22.2 No. 62109-3" throughout. This Standard is intended to be used in conjunction with C22.2 No. 62109-1:16, Safety of power converters for use in photovoltaic systems — Part 1: General requirements (adopted IEC 62109-1:2010, with Canadian deviations) and CSA C22.2 No. 62109-2:16, Safety of power converters for use in photovoltaic power systems — Part 2: Particular requirements for inverters (adopted IEC 62109-2:2011, with Canadian deviations). This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Power Conversion, under the jurisdiction of the CSA Technical Committee on Solar Photovoltaic Energy Systems, the CSA Strategic Steering Committee on Requirements for Electrical Safety, and the CSA Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This Part 3 of IEC 62109 covers the particular safety requirements for electronic elements that are mechanically and/or electrically incorporated with photovoltaic (PV) modules or systems. Mechanically and/or electrically incorporated means that the whole combination of electronic device with the photovoltaic element is sold as one product. Nevertheless, tests provided in this document may also be used to evaluate compatibility of PV modules and electronic devices that are sold separately and are intended to be installed close to each other. Items included in the scope: Electronic devices combined with PV modules that perform functions such as, but not limited to, DC-DC or DC-AC power conversion, active diodes, protection, control, monitoring, or communication. These requirements specifically address such electronic devices used in combination with flat-plate photovoltaic (PV) modules. NOTE It is acknowledged that the physical design of products covered by this scope may vary widely, it is anticipated that the requirements of this document may need to evolve to meet the unique safety requirements of such products, particularly if the photovoltaic element of the product is not of a flat-plate configuration. As an example, this document does not fully address the safety requirements of building-integrated photovoltaics (BIPV) and building-attached photovoltaics (BAPV) products, although they would fall under the scope of this document. The purpose of the requirements of this part of IEC 62109 is to provide additional safety-related testing requirements for the following types of integrated electronics, collectively referred to as module integrated equipment (MIE): a) Type A MIE where the PV element can be evaluated as a PV module according to IEC 61730-1 and IEC 61730-2 independently from the electronic element; b) Type B MIE where the PV element cannot be evaluated as a PV module according to IEC 61730-1 and IEC 61730-2 independently from the electronic element. Items excluded from the scope: PV modules with only one or more bypass diodes as the combined or integrated element. Such products are covered by IEC 61730-1 and IEC 61730-2. Aspects included and excluded from scope: All aspects of IEC 62109-1:2010 apply. Addition to the list "excluded from the scope" is evaluating the MIE to IEC 61215-1.
