SunSpec Modbus for 1547 Certification
SunSpec Modbus, a default communication and interoperability standard specified in IEEE 1547-2018, enables Distributed Energy Resources (DER) and smart inverters to be controlled and monitored by operators, thus enhancing the value of DER and improving grid health. The SunSpec Modbus for IEEE 1547 interface is fully interoperable with IEEE 2030.5 and IEEE 1815, the other communication interfaces identified in IEEE 1547-2018.
Certifying your product to the SunSpec Modbus for IEEE 1547 standard is the simplest and most important step you can take to reduce the time needed for IEEE 1547.1-2020 clause 6 interoperability testing and for achieving UL 1741 SB compliance.
The SunSpec Modbus for 1547 package includes:
- SunSpec Modbus Fact Sheet
- SunSpec Technology Overview
- SunSpec Device Information Model Specification
- SunSpec DER Information Model Specification
- SunSpec Information Model Reference Sheet
- SunSpec Modbus IEEE 1547-2018 Specification, Profile and Implementation Guide

SUNSPEC SVP DASHBOARD and SUNSPEC MODBUS FOR 1547 PLUS PACK
Designed to support software developers and software test labs in preparing products for SunSpec Certification, SunSpec SVP Dashboard may be upgraded to include automated test suites for SunSpec Modbus-enabled devices. The following features are included in the SunSpec Modbus for 1547 Plus Pack:
- A profile for SunSpec Modbus 1547 Certification, including a complete SunSpec Modbus communication verification test that results in a SunSpec Certification mark.
- A test procedure for SunSpec Modbus for 1547 Certification (that references the IEEE 1547.1 interoperability test procedure) and a CA Rule 21 compliance test procedure.
- A test procedure for SunSpec Modbus Certification with the addition of a 1547.1 Interoperability test script.
SunSpec 1547 Initiative News and Updates
With SunSpec Membership and Certification numbers growing at unprecedented levels, the team is hard at work developing resources to further support our members and benefit the broader SunSpec ecosystem. From SunSpec Modbus, to DER Cybersecurity and 2030.5 Profiles for Vehicle to Grid (V2G) and EV Charging applications, SunSpec is committed to providing technical coverage on cutting-edge topics and equipping our Members with the tools needed to thrive in a dynamic regulatory environment.
Entering 2022, the SunSpec Alliance is anticipating yet another year of unprecedented growth. From record-setting additions of new members each month (already seven in January!), to rapidly increasing numbers of products being certified to SunSpec standards, the Alliance is on track to grow in-step with the broader Distributed Energy and Electric Vehicle industries.
While reflecting back on the year’s past, it is clear that the SunSpec Alliance is fueled by an industry of dedicated, hard working individuals and organizations. From our work groups participants, to our webinar attendees, we are consistently impressed by the level of engagement and support from our members and followers.
On November 15th, President Biden passed a 1.2 trillion dollar infrastructure bill, signaling an unequivocal win for the renewable energy industry. With roughly $555 billion allocated to climate and clean energy projects, including tax credits for renewables, energy storage, electric vehicles and the transmission grid, we are excitedly anticipating massive growth in many of the sectors that the SunSpec Alliance is actively developing standards for.
At the core of the SunSpec Alliance ecosystem is a steady momentum of progress driven by the dedicated efforts of our seven primary Work Groups. Consisting of representatives from SunSpec member companies, a designated Work Group leader, and a SunSpec employee, these groups meet weekly or bi-weekly to engage in the active process of standards making. As the year barrels towards a close, we’d like to acknowledge some of the major achievements of these groups and their impacts on the SunSpec ecosystem as a whole.
Addressing new interconnection requirements–including those for advanced inverter electrical functions and corresponding data communication interfaces–is a recurring theme for SunSpec and its members. While some requirements are local, and therefore less urgent to address, at least two national markets, the U.S. and Australia, have implemented changes that have firm deadlines. Companies that meet these deadlines have the potential to reshape the market.
The Race to Market As the deadline to IEEE 1547.1 compliance nears, manufacturers of smart inverters will be racing to complete their UL 1741 SB certifications. With 50 companies, 1000 products, and a turn around time of 10-12 weeks to complete functional...
The Deadline is Approaching! Smart inverters are becoming a key component for ensuring a safe and reliable energy grid in the U.S. and states such as California, Hawaii, New York, and Pennsylvania are mobilizing to adopt IEEE 1547-2018, the national grid...
