IEC 62446-1 establishes the standard for testing, documenting, and maintaining grid-connected PV systems. The standard specifically outlines protocols for direct current (DC) testing, which is used to assess the health of the system at various points of asset life.
Developed in collaboration with the National Renewable Energy Laboratory under a Cooperative Research and Development Agreement (CRADA) funded program.
In order to make these standards more actionable, the Department of Energy has funded a collaborative research initiative with aims to adapt NREL's published into digital, operational, and publicly accessible procedures.
