本推荐规程提供了一个确定独立光伏（PV）系统尺寸的程序。本文件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）。阵列利用率、电池充电效率和系统损耗等问题也会根据它们对系统大小的影响进行考虑。本推荐规程适用于光伏为唯一充电源的所有独立光伏系统。本文件不包括PV hybrid2系统或并网系统。当太阳能/光伏阵列与导线配对时，本文件通常与IEEE Std 1013一起使用- 酸性电池系统。3本推荐规程不包括系统控制器、逆变器、接线或其他系统部件的尺寸。

This recommended practice provides a procedure to size a stand-alone photovoltaic (PV) system. Systems considered in this document 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). The issues of array utilization, battery-charge efficiency, and system losses are also considered in terms of their effect on system sizing. This recommended practice is applicable to all stand-alone PV systems where PV is the only charging source. This document does not include PV hybrid2 systems or grid-connected systems. This document is normally intended to be used in conjunction with IEEE Std 1013 when the solar/PV array is paired with a lead-acid battery systems.3 This recommended practice does not include the sizing of the system controller, inverter, wiring, or other system components.
