IEC 62109-2:2011涵盖了与直流至交流逆变器产品以及除其他功能外具有或执行逆变器功能的产品相关的特殊安全要求，其中逆变器拟用于光伏发电系统。本标准涵盖的逆变器可以是电网互动式、独立式或多模逆变器，可以由以各种阵列配置分组的单个或多个光伏模块供电，并且可以与电池或其他形式的储能装置一起使用。本标准必须与IEC 62109-1联合使用。

IEC 62109-2:2011 covers the particular safety requirements relevant to d.c. to a.c. inverter products as well as products that have or perform inverter functions in addition to other functions, where the inverter is intended for use in photovoltaic power systems. Inverters covered by this standard may be grid-interactive, stand-alone, or multiple mode inverters, may be supplied by single or multiple photovoltaic modules grouped in various array configurations, and may be intended for use in conjunction with batteries or other forms of energy storage. This standard must be used jointly with IEC 62109-1.
