Dave – Related but different. CA Rule 21 and HECO Rule 14H and NE-ISO require equipment tested to UL1741 SA (which outlines what additional functions beyond UL1741 inverters must be capable of) utilizing the appropriate utility Source Requirement Document (SRD). The SRD spells out which UL 1741 SA additional functions -with set point values- each utility wants enabled . This allows for “smart inverter” functionality to prevent undesirable behavior.
The objective of the IEEE 1547.x updates is to harmonize testing across the industry to provide a uniform baseline for “smart” inverter functionality/capability. I believe there will still be specific SRDs – that is, not all tested IEEE 1547-2018 functionality will be enabled by default. I vaguely remember hearing of deadline for certification being at most 18 months after publishing of the standard (which I think means the IEEE1547.1-2020 standard as that actually outlined the testing procedures for listing), which would very roughly be Jan 2022. Also, I think “Hawaii” is being very aggressive with this deadline – I think they (HECO? HELCO? Other?) have set July 1, 2021 as testing deadline? Anyone have more details?
