This standard BS EN 62509:2011 Battery charge controllers for photovoltaic systems. Performance and functioning is classified in these ICS categories:
27.160 Solar energy engineering
IEC 62509:2010 establishes minimum requirements for the functioning and performance of battery charge controllers (BCC) used with lead acid batteries in terrestrial photovoltaic systems. The main aims are to ensure BCC reliability and to maximise the life of the battery.
This publication is to be read in conjunction with IEC 62093:2005.
