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 such as IEEE 1547 / IEC 61000-3-15 / IEC 62116, ensuring proper and safe operation of on-grid products. It has become critical for manufacturers to conduct these tests to prove compliance and to relieve product liability concerns. Chroma’s 61800 Regenerative Grid Simulator 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.
