August 2, 2019, San Jose, California The SunSpec Alliance is pleased to announce that the SunSpec Common Smart Inverter Profile (CSIP) Conformance Test Procedures, APPROVED and made available for free download on May 22, 2018, have been updated to improve clarity and eliminate certain procedures that were determined to be not applicable. 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 Distributed Energy Resource (DER) system. The characteristics of this communication path are described in the CSIP 2.1 specification (available here), developed by the Smart Inverter Working Group (SIWG), and include adherence to the IEEE 2030.5-2018 specification.
