Power line communication for DC shutdown equipment - Communication signal, physical layer

Apstrakt

IEC 63257:2023 applies to photovoltaic (PV) system components and communication networks supporting the communication of the DC shutdown equipment using power line communication.
This document defines how to propagate the operational state of the entire PV system (normal / shutdown) to the individual power production components comprising the PV system. The document also describes requirements and constraints associated with power line communication networks that are used to support this application.
