Membership Benefits

Companies and individuals who want to drive standards in the Distributed Energy industry should join the SunSpec Alliance.

Product Certification

The SunSpec Certification program takes a holistic approach to compliance testing, security, and communication of results and quality control.

SunSpec Ecosystem

SunSpec standards enable interoperability of components and systems, are compatible with diverse utility grids and microgrids around the globe, and support the establishment of Distributed Energy as a financial asset class.

Sunspec Modbus

SunSpec Modbus defines common parameters and settings for monitoring and controlling DERs and their capabilities, such as voltage regulation, setting power factor, and power export limiting. It also structures data to increase interoperability. Leveraging the Modbus1 protocol, widely adopted for industrial electronic devices since the 1980s, SunSpec Alliance created the SunSpec Modbus interface in 2009 and has continually extended it to cover all solar inverters and many other commercially available DERs.

DER Cybersecurity

The SunSpec Alliance is comitted to paving the way for a secure distributed energy infrastructure by creating opportunities for education, collaboration, and standards development for DER Cybersecurity. Participate in work groups, attend webinars, and access exclusive video content here.
