prEN IEC 63257:2022

This document 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 (normal/shutdown) 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 includes conformance test procedures including criteria, which have to be fulfilled to state conformity to this standard. Note 1: It is possible to have systems communicating in different ways to the method covered in this standard. For those systems this standard does not apply. E.g., in systems where all components of the PLC communication are from the same manufacturer. Note 2: Not included in the scope of this standard are: DC shutdown initiator mechanism; disconnection and de-energization. Note 3: This standard does not address whether DC shutdown is a requirement or not.
