US IEC 62509:2010, Battery charge controllers for photovoltaic systems — Performance and functioning

This Uganda Standard establishes minimum requirements for the functioning and performance of battery charge controllers (BCC) used with lead acid batteries in terrestrial photovoltaic (PV) systems. The main aims are to ensure BCC reliability and to maximize the life of the battery. This standard shall be used in conjunction with IEC 62093, which describes test and requirements for intended installation application. In addition to the battery charge control functions, this standard addresses the following battery charge control features:
• photovoltaic generator charging of a battery,
• load control,
• protection functions, and
• interface functions.
This standard does not cover MPPT performance, but it is applicable to BCC units that have this feature.
