Non sono coperti gli SPD per impianti fotovoltaici con accumulo di energia (ad esempio batterie, banchi di condensatori). Gli SPD con terminali di ingresso e uscita separati che contengono un'impedenza in serie specifica tra questi terminali (i cosiddetti SPD a due porte secondo la norma IEC 61643-11:2011) non sono coperti. Gli SPD conformi a questa norma sono progettati peressere permanentemente collegati laddove la connessione e la disconnessione degli SPD fissi possono essere effettuate solo utilizzando uno strumento.

Impianti fotovoltaici situati a terra come centrali elettriche in campo libero caratterizzati da messa a terra multipla e sistema di messa a terra a maglia.

These devices are designed to be connected to the DC side of photovoltaic installations rated up to 1 500 V DC. These devices contain at least one non-linear component and are intended to limit surge voltages and divert surge currents. Performance characteristics, safety requirements, standard methods for testing and ratings are established.\u00a0 SPDs complying with this standard are exclusively dedicated to be installed on the DC side of photovoltaic generators and the DC side of inverters. SPDs for PV systems with energy storage (e.g. batteries, capacitor banks) are not covered. SPDs with separate input and output terminals that contain specific series impedance between these terminal(s) (so called two-port SPDs according to IEC 61643-11:2011) are not covered. SPDs compliant with this standard are designed to be permanently connected where connection and disconnection of fixed SPDs can only be done using a tool. This standard does not apply to portable SPDs.\r\n\r\n<strong>IEC 61643-32:2017\u00a0<\/strong>\r\n<strong>Low-voltage surge protective devices \u2013 Part 32: Surge protective devices connected to the d.c. side of photovoltaic installations \u2013 Selection and application principles<\/strong>\r\n\r\nIEC 61643-32:2017 describes the principles for selection, installation and coordination of SPDs intended for use in Photovoltaic (PV) systems up to 1 500 V DC and for the AC side of the PV system rated up to 1 000 V rms 50\/60 Hz. The photovoltaic installation extends from a PV array or a set of interconnected PV-modules to include the associated cabling and protective devices and the inverter up to the connection point in the distribution board or the utility supply point. This part of IEC 61643 considers SPDs used in different locations and in different kinds of PV systems:PV systems located on the top of a building. PV systems located on the ground like free field power plants characterized by multiple earthing and a meshed earthing system. The term PV installation is used to refer to both kinds of PV systems. The term PV power plant is only used for extended free-field multi-earthed power systems located on the ground.
