California Rule 21 requires that, by default, Distributed Energy Resources within Investor Owned Utilities (IOU) must utilize the IEEE 2030.5-2018 networking standard in the manner described in the Common Smart Inverter Profile.
Products certified by SunSpec to the IEEE 2030.5 standard for wide area communication can be installed on sites connected to California Investor Owned Utilities and have the confidence in their compatibility with local area communication protocols like the freely available SunSpec Modbus Standards.
