SunSpec Alliance Webinar: SunSpec Express Test™ Program Launch


SunSpec Alliance is happy to announce SunSpec Express Test™, a new, fast method for Distributed Energy Resource (DER) manufacturers to earn SunSpec Modbus for IEEE 1547 certification for DER products. Manufacturers apply online at for the SunSpec Express Test™ program and enroll for a timeslot to have the full test sweep executed within two weeks. For products that comply with the SunSpec Modbus for IEEE 1547 communication standard, testing can be done in 48 hours.

Why This Service Is Needed. SunSpec Modbus is a standard communication interface required by the IEEE 1547-2018 electrical standard for DER. Compliance with IEEE 1547 is validated via UL 1741 SB, a listing needed by DER products installed in the U.S. and Canada. Developing a SunSpec interface, linking it to the electrical functions of a DER product, and evaluating it across a wide range of use cases has proven to be a challenge for manufacturers and their test partners. Testing times grow and interoperability suffers when SunSpec interfaces are not fully vetted.
