This part of IEC 62446 defines the information and documentation required to be handed over to a customer following the installation of a grid-connected PV system. It also describes the commissioning tests, inspection criteria and documentation expected to verify the safe installation and correct operation of the system. It can also be used for periodic retesting.
This document 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 document 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.
Throughout this document, there are various requirements highlighted from the "Applicable Installation Standard" (AIS). Where a local AIS does not have the specific requirement detailed in this document, then the requirement from IEC 62548-1 shall be used.
Documentation, test and inspection requirements for systems incorporating a DC coupled battery are included in the scope of this document.
NOTE 1 Batteries may also be AC coupled to a PV system, but as such are considered out of the scope of this document.
Detailed system performance validation is not within the scope of this document.
NOTE 2 IEC 61724 series should be consulted for PV system performance validation
This document does not address off-grid systems, or concentrating PV systems, however many of the parts may apply.
NOTE 3 IEC TS 62257-100 provides an overview of the 62257 series, which cover off-grid renewable energy and hybrid products and systems.
