AMENDMENT 1 2 IEC 62894:2014/AMD1:2016 IEC 2016 FOREWORD This amendment has been prepared by the IEC technical committee 82: Solar photovoltaic energy systems.
12、 The text of this standard is based on the following documents: FDIS Report on voting 82/1175/FDIS 82/1205/RVD Full information on the voting for the approval of this amendment can be found in the report on voting indicated in the above table. The committee has decided that the contents of this amen
13、dment and the base publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingu
14、al version of this publication may be issued at a later date. _ 2 Normative references Add, after the reference IEC 60721-2-1, the following new reference: IEC 61683, Photovoltaic systems Power conditioners Procedure for measuring efficiency 3 Terms and definitions Add, after entry 3.1.7, the follow
15、ing two new terms and definitions: 3.1.8 maximum short-circuit DC input current I scmaxabsolute maximum total PV array short circuit current (DC) that the inverter is rated to have connected to its input terminals, under worst-case conditions of ambient temperature, irradiance, etc. Note 1 to entry:
16、 This term is based on the term I sc, PVin IEC 62109-1. It refers to the absolute maximum current the DC input to the inverter is designed for under conditions of expected use. This differs from the simple sum of the marked I scratings of the connected PV modules, since those markings are based on s
17、hort-circuit conditions under standard test conditions, and may be exceeded in temperatures or irradiance levels different from the standard levels. IEC 62894:2014/AMD1:2016 3 IEC 2016 3.1.9 rated input power P dc,rinput power (DC) at rated input voltage and rated power (AC) Add, after the entry 3.2
18、.12, the following new terms and definitions: 3.3 Other optional parameters 3.3.1 time to start-up t startdefault start-up delay time of the inverter under normal conditions 3.3.2 rated AC current I ac,rrated AC current at rated power (P ac,r ), and rated grid voltage (V ac,r ) 3.3.3 maximum AC outp
19、ut power P acmaxmaximum continuous active power the inverter can deliver under specified voltage or temperature conditions within the inverters rated range of operation Note 1 to entry: The maximum AC output power (P acmax ) may differ from rated power (P ac,r ) if the inverter is capable of deliver
20、ing additional power under specific conditions, for example at temperatures below the inverters maximum ambient temperature rating, or within specified DC voltage ranges. 3.3.4 total harmonic distortion THD total harmonic distortion measured in the output current at rated power (P ac,r ), divided by
21、 the full rated fundamental current Note 1 to entry: This definition of “total harmonic distortion“ applies to this document only. 3.3.5 maximum efficiency maxmaximum measured DC to AC efficiency recorded, tested in accordance with IEC 61683 4.1 General Add, after the first paragraph, following new
22、paragraph: The following subclauses define the minimum required information, which should be included on the datasheet for a photovoltaic inverter. Additional information can however be supplied by the manufacturer. 4.2 Short description Delete, in this subclause, the last sentence, as follows: The
23、topology type should be indicated too. 4.4.2 Delete, in the list of parameters, the the last two parameters, as follows: 4 IEC 62894:2014/AMD1:2016 IEC 2016 P dcmax , t startAdd, in the list of parameters, before P dc,r , the following parameter: I scmaxAdd, at the end of this subclause, the followi
24、ng new paragraph: The list of parameters does not include a maximum DC power rating and it is recommended that such a term not be included in product data sheets. This is due to significant inconsistencies in how the term is used, defined, and interpreted. The maximum array size that can be connecte
25、d to an inverter should be determined by the maximum short-circuit DC input current rating and the maximum input voltage rating. 4.4.3 Delete, in the list of parameters, the last four parameters, as follows: I ac,r , P acmax , THD, maxAdd, after 4.4.3, the following new subclause: 4.4.4 The followin
26、g parameters are not required on the product data sheet, but may be included if considered useful: t start , I ac,r , P acmax , THD, maxIf the parameters P acmax , and maxare included, the product data sheet shall specify: the conditions at which the maximum AC output power can be delivered; the DC
27、and AC voltage and ambient conditions at which the maximum efficiency is reported, tested in accordance with IEC 61683. 4.6 Safety Delete the last two dashes, as follows: the method of active detection of loss of mains should be clearly indicated; time to reconnect after disconnection due to loss of
28、 mains should be indicated. Add, after the dashed list, the following sentence: Additional information such as the minimum allowed time for an inverter to reconnect to the grid after disconnection due to loss of mains, or the method of active detection of loss of mains, may be included if useful for
29、 the particular country or market. 4.8.2 Other characteristics Delete the last dash, as follows: Warranty period should be indicated. IEC 62894:2014/AMD1:2016 5 IEC 2016 5 Details on the name plate Delete, in the last paragraph above Figure 3, the second sentence, as follows: The material of the name plate shall be metallic. _ INTERNATIONAL ELECTROTECHNICAL COMMISSION 3, rue de Varemb PO Box 131 CH-1211 Geneva 20 Switzerland Tel: + 41 22 919 02 11 Fax: + 41 22 919 03 00 infoiec.ch www.iec.ch
