本指南提供了帮助确定独立光伏系统阵列和电池大小的信息。本指南中考虑的系统包括作为唯一电源的光伏和用于储能的电池。这些系统通常还采用控制装置来保护电池不被过度充电或充电不足，并可能采用功率转换子系统（逆变器或转换器）。 本指南适用于光伏为唯一充电源的所有独立光伏系统。本指南不包括光伏混合系统或并网系统。本指南仅适用于铅酸蓄电池；镍镉和其他电池类型不包括在内。本指南不包括系统控制器、逆变器、接线或其他系统部件的尺寸。

This guide provides information to assist in sizing the array and battery of a stand-alone photovoltaic system. Systems considered in this guide consist of PV as the only power source and a battery for energy storage. These systems also commonly employ controls to protect the battery from being over- or undercharged, and may employ a power conversion subsystem (inverter or converter). This guide is applicable to all stand-alone PV systems where PV is the only charging source. This guide does not include PV hybrid systems nor grid-connected systems. This guide covers lead-acid batteries only; nickel-cadmium and other battery types are not included. This guide does not include the sizing of the system controller, inverter, wiring, or other system components.
