本推荐规程描述了独立光伏系统中通风式和阀控式铅酸蓄电池的尺寸确定方法。安装、维护、安全、测试程序以及对铅酸以外电池类型的考虑超出了本推荐规程的范围。混合和并网光伏系统的电池尺寸超出了本推荐规程的范围。与独立光伏装置相关的其余电气系统的推荐规程也超出了本推荐规程的范围。给出了各种典型系统应用的尺寸调整示例。优化电池成本的迭代技术，包括考虑电池尺寸、光伏阵列尺寸和天气之间的相互关系，超出了本推荐实践的范围。

This recommended practice describes a method for sizing both vented and valve-regulated lead-acid batteries in stand-alone PV systems. Installation, maintenance, safety, testing procedures, and consideration of battery types other than lead-acid are beyond the scope of this recommended practice. Sizing batteries for hybrid and grid-connected PV systems is beyond the scope of this recommended practice. Recommended practices for the remainder of the electrical systems associated with stand-alone PV installations are also beyond the scope of this recommended practice. Sizing examples are given for various representative system applications. Iterative techniques to optimize battery costs, which include consideration of the interrelationship between battery size, PV array size, and weather, are beyond the scope of this recommended practice.
