DANSK DSF/PREN IEC 61439-8 PDF

This part of the IEC 61439 series specifies requirements for the design and verification of assemblies for use in photovoltaic installations. Such photovoltaic assemblies are designated PVAs. PVAs have the following characteristics: – assemblies used for the combination or recombination of electrical energy in DC systems for which the voltage does not exceed 1  500 V DC and supply to an AC network where the voltage does not exceed 1  000 V AC; – stationary assemblies with an enclosure; – assemblies intended for operation by authorised persons (see 3.7.17 of IEC 61439-1:2020), but can be located in an area accessible to ordinary persons; – suitable for indoor or outdoor installation. NOTE: PV installations having PV modules with micro-inverters that are connected directly to inter-connection assemblies according to IEC 61439-2 or IEC 61439-3 are not covered by this document. This document identifies definitions, specifies the service conditions, details the construction requirements, defines the technical characteristics, and provides verifications for PVAs. PVAs can also include control and or signaling devices associated with the distribution of electrical energy.
