Sunspec 1547 Initiative
AUTOMATING IEEE 1547.1-2020 TESTING USING SUNSPEC MODBUS
The goal of the SunSpec 1547 initiative is to reduce UL 1741 SB testing by at least 50% by automating IEEE 1547.1-2020 testing and SunSpec Modbus for IEEE 1547-2018 Certification testing.
Utilizes Standard Interface
The IEEE 1547-2018 standard precisely defines the relationship between the physical functions of an inverter and the standard SunSpec Modbus communication interface.
ENSURES IEEE 1547.1-2020 Compliance
Obtaining SunSpec Modbus for IEEE 1547-2018 certification is the single most important factor for ensuring that a DER device will pass IEEE 1547.1-2020 compliance tests quickly.
Speeds Time to Market
By automating IEEE 1547.1-2020 testing, manufacturers and test labs will reduce testing time by 50% as compared to current methods, thus saving money and expediting time to market.Â
