Communications solutions for the rapidly changing smart energy environment.
Our software based gateway solutions provide communications management of DERs at the grid-edge. Congruence.IQ Gateways are available in various form factors to support asset owner and utility operational goals – including gateways that implement advanced control capabilities for legacy inverters and systems.
The Smart Energy Profile 2.0 (SEP 2.0) is an application for connecting consumer owned smart energy devices to the Smart Grid. SEP 2.0 is designed to work over any technology that supports the Internet Protocol (IP). This standard is not necessarily limited to transmission of energy usage information and can support many other types of information (e.g., pricing information, demand response events, billing information, prepayment information) and commodities (e.g., natural gas, water). SEP 2.0 is also used for communication between an electric vehicle and a charging station.
After the SEP 2.0 standard was completed, it was adopted as IEEE 2030.5; and, for all intents and purposes they are considered the same.
California Rule 21 requires that, by default, Distributed Energy Resources within Investor Owned Utilities (IOU) must utilize the IEEE™ 2030.5-2018 (SEP 2.0) networking standard in the manner described in the Common Smart Inverter Profile.
Since its adoption in 2013, the IEEE 2030.5 protocol has been updated at least once, and many industry experts anticipate further updates as technologies advance and cyber security requirements evolve. Because of these evolutions, it is important to evaluate the upgrade-ability of any solution you select to the most current version of IEEE 2030.5 to provide the most functionality, value and security.
The SunSpec Certified™ program is designed to instill buyer confidence in SunSpec member product solutions by establishing objective criteria for verifying the compliance of communication interfaces of SunSpec member company products. In addition, certified products are allowed to participate in the SunSpec Certified Public Key Infrastructure (PKI) program for authenticating and securing communications according to California Rule 21 compliance requirements.
