Scope1.1 This 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.
1.2 This 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.
1.3 This Standard does not consider the implication of storage battery systems with a nominal terminal voltage in excess of 150 V.
1.4 This Standard does not cover installation or maintenance, nor does it deal with detailed sizing procedures or mechanisms fo r 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.
