1 Scope This part of the IEC 61439 series specifies requirements for the design and verification of low-voltage switchgear and controlgear assemblies for use in photovoltaic installations. PVAs have the following characteristics:
assemblies used for the combination of electrical energy in DC systems for which the input and output voltage does not exceed 1 500 V DC; assemblies supplied from an AC network where the voltage does not exceed 1 000 V AC for auxiliary and control purposes; stationary assemblies with an enclosure; assemblies intended for operation by authorised persons (see IEC 61439‑1:2020, 3.7.17 ), but can be located in an area accessible to ordinary persons (see IEC 61439‑1:2020, 3.7.16 ); suitable for indoor or outdoor installation.
NOTE 1 PV installations having PV modules with micro-inverters that are connected directly to inter-connection assemblies according to
