农村电气化离网系统用可再生能源和混合系统 第9-8部分：集成系统 - 额定功率≤350W的独立可再生能源产品要求

[中文适用范围]： IEC TS 62257-9-8:2025 RLV 包含正式的国际标准及其红线版本。红线版本仅提供英文版，为您提供一种快速简便的方法来比较官方IEC标准与其前一版本之间的所有更改。 IEC TS 62257-9-8:2025 提供了离网可再生能源产品的质量、耐用性和广告真实性的基线要求，以保护此类产品的消费者。这些要求的评估基于 IEC TS 62257-9-5 中描述的测试。该文件可以单独使用或与其他涉及离网可再生能源产品组件安全和耐用性的国际标准一起使用。 本文件适用于具备以下特性的独立可再生能源产品： - 该产品由光伏（PV）模块供电或由电磁机械发电装置（如发电机）供电，或者设计用于通过电网给电池或其他储能设备充电以供离网使用。这些要求也可能适合作为评估其他电源产品的质量的指导。 - 光伏模块或其他发电装置的最大功率额定值小于或等于350瓦。 - 评估的系统包括所有负载（照明、电视、收音机、风扇等）及其负载适配电缆，这些负载是作为套装的一部分销售或包含在套件中组件内的。 - 光伏模块的最大功率点电压以及套件中的任何其他组件的工作电压不超过35伏。对于符合适当安全标准的交流电至直流电转换器和包括光伏模块（或组合光伏模块）且开路电压大于35伏并满足IEC TS 62257-9-5评估之外额外安全要求的系统，此规定有所例外。 本文件包含与安全相关的条款；然而，并不旨在成为全面的安全标准。特别是，本文件并不打算替代如用于包括在独立可再生能源产品中的收音机和电视等器具的IEC 62368-1或IEC 60335系列电器的安全标准。也不打算取代IEC 62281或UN 38.3对于电池运输安全的要求，或者用于独立可再生能源产品外其他用途的光伏模块的安全要求（如IEC 61730-1和IEC 61730-2）。 [外文原描述]： IEC TS 62257-9-8:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 62257-9-8:2025 provides baseline requirements for quality, durability and truth in advertising to protect consumers of off-grid renewable energy products. Evaluation of these requirements is based on tests described in IEC TS 62257-9-5. This document can be used alone or in conjunction with other international standards that address the safety and durability of components of off-grid renewable energy products. This document applies to stand-alone renewable energy products having the following characteristics: - The products are powered by photovoltaic (PV) modules or electromechanical power generating devices (such as dynamos), or are designed to use grid electricity to charge a battery or other energy-storage device for off-grid use. The requirements may also be appropriate as guidance for evaluating the quality of products with other power sources, such as thermoelectric generators. - The peak power rating of the PV module or other power generating device is less than or equal to 350 W. - The system evaluated includes all the loads (lighting, television, radio, fan, etc.) and load adapter cables that are sold or included as part of the kit or integrated into kit components. - The PV module maximum power point voltage and the working voltage of any other components in the kit do not exceed 35 V. Exceptions are made for AC-to-DC converters that meet appropriate safety standards, and systems that include PV modules (or combinations of PV modules) with open-circuit voltage greater than 35 V that meet additional safety requirements beyond those assessed in IEC TS 62257-9-5. This document includes provisions related to safety; however, it is not intended to be a comprehensive safety standard. In particular, this document is not intended to be used as an alternative to safety standards such as IEC 62368-1 or the IEC 60335 series for appliances such as radios and televisions that are included with stand-alone renewable energy products. Nor is it intended to replace the safety requirements of IEC 62281 or UN 38.3 for battery safety during transport, or safety requirements of IEC 61730-1 and IEC 61730-2 for PV modules intended for use outside the context of stand-alone renewable energy products.
