IEC 62257-9-5:2018和IEC 62257-9-8:2020中文版要点解析

Key points analysis of IEC 62257-9-5:2018 and IEC 62257-9-8:2020 Chinese version

全球能源短缺,气候恶化已成为全人类面临的重大问题,离网太阳能产品作为重要的新能源产品之一,是解决能源短缺等问题的主要途径之一。离网太阳能光伏产品通过光伏组件发电,并通过储能电池和控制装置,可为照明、家用电器等产品提供能源供给。2022年全球首次出版发行的两项离网太阳能产品IEC标准中文版为全球的离网太阳能产品提供了统一的测试和评价标准。本文结合实验室多年的检测经验和数据,对两项IEC标准中文版中的重要项目详细解析,便于生产企业以及相关标准的使用者更加深入地理解标准技术要求,从而提升离网太阳能产品质量。

Global energy shortage and climate deterioration have become major problems facing all mankind.Using off-grid solar products,as one of the important new energy products,is one way to solve energy shortage and other problems.Off-grid solar photovoltaic products generate electricity through photovoltaic modules and provide energy supply for lighting,household appliances and other products through energy storage batteries and control devices.In 2022,two Chinese version of the IEC standards for off-grid solar products are released for the first time in worldwide,which provide a unified test method and an evaluation standard for off-grid solar products.Based on many years of testing experiences,the laboratory analyzed some important items according to the Chinese version of two IEC standards in detail,which could help manufacturers and users of standards well understand the technical requirements of the standards and could contribute to the improving quality of off-grid solar products.
