Low-voltage surge protective devices - Surge protective devices for specific application including d.c. - Part 12: Selection and application principles - SPDs connected to photovoltaic installations

Scope

This Technical Specification describes the principles for selection, location, coordination and operation of SPDs to be connected to PV installations. The d.c. side is rated up to 1 500 V d.c. and the a.c. side, if any, is rated up to 1 000 V rms 50 Hz. The electrical installation starts from a PV generator or a set of interconnected PV modules with their cables, provided by the PV generator manufacturer, up to the user installation or the utility supply point. For PV installations including batteries, additional requirements will be necessary. NOTE 1 HD 60364-7-712, CLC/TS 61643-12 and EN 62305-4 are also applicable. NOTE 2 This Technical Specification deals only with SPDs, and not with SPDs components integrated inside equipment.
