1,this inverter integrated system maximizes energy harvest, increases system reliability, and implifies design, installation and management.
The small type wind grid tie power inverter can obtain the wind energy from wind turbine, and can tie to the grid through its output cables with no extra equipment. The installation is very convenient and reliable.
2,This inverter combining with small grid tie inverter and wind turbine as ‘SGWT’. The system includes wind turbine and small grid tie inverter and installation kit, and some “SGWT”also will include controller, dump load resistor.
The inverter can be connected to any outlets of utility grid at house. The small grid tie inverter monitors the volume, frequency and phase of the home utility grid, then produce pure sine wave AC power that the frequency and phase are as same as the grid's, and the volume is a bit higher than the grid's, then according to the current controlled PWM, to control the output power to the grid. The small grid tie inverter just puts out power when the home grid is on.
3,When the wind turbine is rotating, and the output of the voltage is in the range of the rated input voltage of the inverter, the wind turbine will produces power, and the grid tie inverter will change the power from wind turbine to the home grid. When the total power of electric apparatus that are using in the house is larger than the output power of the inverters, these power from the inverters will be consumed in the house, this will slow down the power meter,otherwise, the difference of the output power of the inverter between the total used power of the apparatus will go out from the house to the out grid.
