Small Wind grid-connected Inverter


　

Small wind turbine grid-connected power system includes small wind turbine dump load, grid -connected inverter, meter and power switchboard. When wind speed reaches the cut-in-speed, the AC power from the wind turbine will be fed in the utility grid after rectifying and inverting. If the wind speed is too large, part of the dump load will be connected to the wind turbine to keep the constant power to fed in the utility grid.
