Power One Aurora PVI-6000-OUTD-US-W Wind Inverter 6000W, non isolated 240VAC 50-600VDC, 5yr Warranty. HIGH PERFORMANCE REDEFINED The switching technology utilized in the Aurora inverters includes state-of-the-art for silicon Power Devices such as Silicon Carbide Diodes, CoolMOSTM and Insulated Gate Bi-polar Transistors (IGBT’s) to reduce switching losses. Aurora has been designed with large de-rating criteria on all critical components, achieving an extremely robust and reliable inverter designed to last for 25 years and more. With this design concept we achieve peak efficiencies of over 94%. Total current harmonic distortion, on the other hand, is typically less than 2% through the use of high-frequency switching techniques. Another exclusive advantage is Aurora’s two source circuit inputs, each with its own MPPT (Max Power Point Tracker) for installations with multiple arrays
