We are proud to announce that QualityLogic, an industry leader in software testing tools and services, has officially joined us as the first SunSpec Authorized Test Software Provider. QualityLogic has been developing test tools for over three decades and is a proven partner in the Smart Energy sector. They were the first to develop IEEE 2030.5 test tools, starting in 2010. In 2018, QualityLogic became a key partner in developing the SunSpec CSIP test specification. The QualityLogic IEEE 2030.5 test tools were the first to implement the SunSpec CSIP CA Rule 21 test specification and are currently being used by leading test labs and vendors around the world.
