E DIN EN IEC 63257 VDE 0126-302:2024-08

This international draft-standard applies to Photovoltaic (PV) system components and communication networks supporting the communication of the DC shutdown equipment using powerline communication. This standard defines how to propagate the operational state of the entire PV system to the individual power production components comprising the PV system. The standard also describes requirements and constraints associated with power line communication networks that are used to support this application. This standard describes the supplementary use of this communication for monitoring purposes as an option. This standard includes conformance test procedures including criteria, which have to be fulfilled to state conformity to this standard.
