Title 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
Project Number 22529
Abstract/Scope This Technical Specification deals with the protection of PV installations against overvoltages. It deals with the protection of the PV installation against surge overvoltages induced by direct and indirect lightning strikes. If such a PV installation is connected to an AC-supply system this document is applicable as a complement of HD 60364 4 443, HD 60364 5 534 and HD 60364 7 712 and also CLC/TS 61643 12. Surge protective devices (SPD) installed on the AC side shall comply with EN 61643 11. NOTE 1 Due to the very specific electrical setup of PV installations on the DC side, only surge protective devices especially dedicated to PV installations shall be used to protect the DC side of such installations. NOTE 2 Taking into account the sensitivity and of the setting up of the photovoltaic modules, a detailed attention must be paid to the protection of the structure itself (building) against direct effects of the lightning; this subject is covered by EN 62305 series.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
