范围:1.1本标准提供了一种展示光伏系统蓄电池选择相关技术信息的方法，以及该信息的精度。注:光伏（PV）电力系统的一个显著特点是，可用充电功率的不可预测性和限制性，因此对蓄电池的充放电循环也有限制。1.2本标准包括验证蓄电池容量、效率和寿命的程序。注:不可能测试所有电池型号和类型。为此，给出了一种描述数据质量和来源的方法。1. 3.该标准不考虑蓄电池额定值超过150 V.1.4的蓄电池系统的含义。该标准不包括安装或维护，也不涉及与其他光伏系统部件接口的详细施胶程序或机构。1.5本标准仅包含光伏应用特有的测试。本标准不包括其他公认标准中现有的机械或环境试验程序。本标准的使用者应判断这些其他标准是否适用于其应用。

Scope:1.1This Standard provides a method of presenting technical information relating to the selection of storage batteries for photovoltaic systems and to the precision of that information.Note:A distinguishing feature of photovoltaic (PV) power systems is the unpredictability and limitation on the amount of charging power available and hence on the charge-d ischarge cycles imposed on the storage battery.1.2This Standard includes procedures designed to verify the capacity, efficiency, and longevity of storage batteries.Note:It is not practicable to test all battery models and types. For this reason a method of characterizing the quality and source of the data is given.1.3This Standard does not consider the implication of storage battery systems with a nominal terminal voltage in excess of 150 V.1.4This Standard does not cover installation or maintenance, nor does it deal with detailed sizing procedures or mechanisms for interfacing with other PV system components.1.5This Standard incorporates only those tests that are unique to photovoltaic applications. This Standard does not include reference to mechanical or environmental test procedures that now exist in other recognized standards. The users of this Standard should judge the appropriateness of these other standards for their application.
