WHAT IS IT
A CLEAR PATH TO COMPLIANCE WITH THE IEEE 1547-2018 COMMUNICATIONS MANDATE
The cost of supporting SunSpec Modbus is low because the physical network interface exists in most DER devices.
SunSpec provides royalty-free specifications, reference software, and development tools to help implementation teams get their products to market.
IEEE 1547-2018 COMPLIANCE
Referenced in IEEE 1547-2018, SunSpec Modbus is the quickest way to insure compliance.

SUNSPEC MODBUS WORK GROUP
Open exclusively to Members of the SunSpec Alliance, the SunSpec Modbus Work Group works on updates to the SunSpec Modbus specifications. The updates include additions to SunSpec information modeling, new DER information models for IEEE 1547-2018 support, and a SunSpec Modbus Conformance Profile for IEEE 1547-2018 compliance.
A Clear Path to Compliance with IEEE 1547-2018
SunSpec Modbus is an open standard, referenced in IEEE 1547-2018, that enables interoperability amongst DER system components. SunSpec specifications reduce the cost of system implementation. They enable applications to be written using a single, standard view of the components comprising a solar plant, independent of manufacturer and model; and enable devices to maximize their potential deployment possibilities by interoperating with applications and other protocols such as IEEE 2030.5 and IEEE 1815.
