IEEE 2030.5 / V2G AC

IEEE 2030.5/V2G AC PROFILE

This profile serves to assist EVSE and PEV manufacturers, operators, and system integrators to implement the SAE J3072 requirements using the IEEE 2030.5 protocol. SAE J3072 establishes requirements for a grid support inverter system function which is integrated into a plug-in electric vehicle (PEV) which connects in parallel with an electric power system (EPS) by way of conductively coupled, electric vehicle supply equipment (EVSE).

The IEEE 2030.5/V2G AC Specification Package includes:

  • IEEE 2030.5 / V2G AC (TEST)

SUNSPEC RAPID SHUTDOWN

SUNSPEC RAPID SHUTDOWN

The SunSpec Certified program for Rapid Shutdown verifies compliance to the SunSpec Communication Signal for Rapid Shutdown Functional Specification to meet the requirement established by National Electrical Code (NEC) 2017. PV module-level power control and safety (“rapid shutdown”) is required in 24 states starting in January 2019 and will affect millions of PV panels and all solar inverters. This standard is tested using UL 1741 SA criteria.
