Market demand for Distributed Resource (DR) products such as PV inverters and wind energy systems is steadily growing as the world strives for clean renewable energy sources. This demand has created a need for rigorous
regulation testing to standards like UL 1741SA / IEEE 1547 / IEC 62116 which ensure proper and safe operation of on-grid products. It has become critical to manufacturers to conduct these tests in order to prove compliance and to relieve product liability concerns. Chroma’s new 61800 family of Grid Simulators has been designed to fulfill these test requirements by providing a full 4 quadrant, fully regenerative, grid simulator with advanced features for compliance, safety and product verification testing.
