Sungrow completes grid-forming validation

Sungrow, a leading PV inverter and energy storage system provider, successfully completed the world's first large-scale grid-forming full-scenario validation. The program, independently verified by TÜV Rheinland, covered 14 scenarios over 138 hours, meeting multiple international standards. This breakthrough addresses critical challenges in grid stability as global power systems transition to high shares of renewable energy. Key tests included short-circuit performance, inertial response, and black start capabilities, demonstrating Sungrow's system's ability to maintain connection, restore frequency stability, and restart facilities without external support. Henry Liu of Sungrow highlighted the significance of these results for the large-scale deployment of grid-forming technologies, which align with grid codes in Europe, Australia, and China.
