May 22, 2018, San Jose, California The SunSpec Alliance is pleased to announce that the SunSpec Common Smart Inverter Profile (CSIP) Conformance Test Procedures have reached APPROVED status and are now available for free download and use. This means that manufacturers, system integrators, and implementors can verify products for compliance to California Rule 21 phase 2 (communication) and phase 3 (control) requirements.
SunSpec CSIP Conformance Test Procedures address the communications path between the Investor Owned Utility (IOU) network and aggregator or DER system. The characteristics of this communication path are described in the CSIP 2.1 specification (available here), developed by the Common Smart Inverter Working Group (SIWG), and include adherence to the IEEE 2030.5 specification.
