本推荐规程适用于与公用事业并联运行的公用事业互连光伏发电系统，并使用静态（固态）逆变器将直流电（dc）转换为交流电（ac）。（本推荐规程不适用于使用旋转逆变器的系统。）本推荐规程描述了针对以下问题的具体建议:？斯莫拉？额定功率为10千瓦或以下的系统，例如可用于个人住宅的系统。这些建议将为这些较小的系统提供更大的标准化，从而减轻光伏系统安装商和互联公用事业公司的工程和设计负担。 A.中间派？应用范围从10千瓦到500千瓦不等，遵循与小型系统相同的一般准则。互连公用设施可能需要具有可调设定点或其他自定义功能的选项，具体取决于光伏系统对其互连的公用设施系统部分的影响。A.拉赫亚？大于500千瓦的系统可结合各种标准化功能和定制要求，具体取决于光伏系统对其互连的公用事业系统部分的影响。随着光伏系统的规模相对于公用设施系统容量的增长，预计将对公用设施接口进行更大程度的定制工程

This recommended practice applies to utility-interconnected PV power systems operating in parallel with the utility and utilizing static (solid-state) inverters for the conversion of direct current (dc) to alternating current (ac). (This recommended practice does not apply to systems utilizing rotating inverters.) This recommended practice describes specific recommendations for "small" systems, rated at 10 kW or less, such as may be utilized on individual residences. These recommendations will provide greater standardization for these smaller systems, thereby reducing the engineering and design burden on both the PV system installer and the interconnecting utility. "Intermediate" applications, ranging from over 10 kW up to 500 kW, follow the same general guidelines as small systems. Options to have adjustable setpoints or other custom features may be required by the inter-connecting utility, depending on the impact of the PV system on the portion of the utility system to which it is interconnected. "Large" systems, greater than 500 kW, may combine various standardized features as well as custom requirements, depending on the impact of the PV system on the portion of the utility system to which it is interconnected. A greater degree of custom engineering of the utility interface is to be expected as the size of the PV system grows in relation to utility system capacity
