Secondary cells and batteries for photovoltaic energy systems (PVES)

The IEC 61427 Ed.2 applies to all lead-acid and nickel-cadmium cells and batteries for photovoltaic energy systems (PVES). This standard gives general information relating to the requirements of the secondary batteries used in PVES and to the typical methods of test used for the verification of batteries performances. The objective is to assist the specifier in the understanding of the purpose of each test and provide guidance on a suitable requirement that will result in the battery meeting the needs of a particular application and operation condition
