IEC/TS 62548:2013(E) sets out design requirements for photovoltaic (PV) arrays including d.c. array wiring, electrical protection devices, switching and earthing provisions. The scope includes all parts of the PV array up to but not including energy storage devices, power conversion equipment or loads. The object of this Technical Specification is to address the design safety requirements arising from the particular characteristics of photovoltaic systems. Attention is drawn to a project in the IEC 60364 series under joint development between IEC TCs 64 and 82, which will, when published, cancel and replace the present technical specification.
