applications. This manual details the safe installation and operation of the Sunshine Grid Tie Inverter.
This integrated system maximizes energy harvest, increases system reliability, and simplifies design, installation, and management.
The small type of wind grid tie power inverter can obtain the wind energy from wind turbines and tie to the grid through its
output cables with no extra equipment. The installation is very convenient and reliable.
We call a system combining with a small grid tie inverter and a wind turbine as "SGWT". The system includes a wind turbine and a
small grid tie inverter, and a set of the installation kit. Some "SGWT" also will include a controller, dump load resistor.
The inverter can be connected to any outlets of the utility grid at the house. The small grid tie inverter monitors the volume,
frequency, and phase of the home utility grid, producing pure sine wave AC power that the frequency and phase are the same as the
grids. 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 puts out power when the home grid is on.
When the wind turbine is rotating, and its output of the voltage is in the range of the rated input voltage of the inverter, the
wind turbine will produce power, and the grid tie inverter will change the power from the wind turbine to the home grid. When the
total power of the electric appliance that is using in the house is
larger than the output power of the inverters, this 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 appliance will
go out from the house to the out grid.
