FG2000
FG2000inverter is a series of high performance and low noise inverter independently developed by WindSun with a brand-new idea and a simple design. With increased stability, this series has a raft of practical and advanced functions for operation and control, like simple vector-based PI controller, light load oscillation suppression, detection of input and/or output phase loss, re-starting at the tracked rotation speed, flexible input/output terminals, online changes of parameters, auto-identification if signal transmission failures, storage of shut-down and power-off parameters, wobbulator control and RS485 control. WindSun provides equipment manufacturers and the end users with highly integrated solutions which are greatly helpful for lowering system purchase and operation cost and increasing system reliability.
