DIN EN 62446-1:2016-12

Grid connected PV systems are expected to have a lifetime of decades. Only by the provision of adequate documentation at the outset can the long term performance and safety of the PV system and works, on or adjacent to the PV system, be ensured. This part of IEC 62446 is for use by system designers and installers of grid connected solar PV systems as a template to provide effective documentation to a customer. By detailing the expected commissioning tests and inspection criteria, it is also intended to assist in the verification/inspection of a grid connected PV system after installation and for subsequent re-inspection, maintenance or modifications. This part of IEC 62446 defines the different test regimes expected for different solar PV system types to ensure that the test regime applied is appropriate to the scale, type and complexity of the system in question. This part of IEC 62446 has been prepared exclusively for grid connected PV systems that do not utilize energy storage (such as batteries) or hybrid systems. It refers to IEC/TS 62548:2013, which is in the process of being transformed into an International Standard. The responsible committee is DKE/K 373 "Photovoltaische Solarenergie-Systeme" ("Photovoltaic solar power systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
