The grid-tie inverter can transfer wind energy from wind generators directly into the home grid using no extra equipment. It can be connected to any outlet (conventional network) in the home. The grid-tie inverter controls the phase and the frequency and voltage of the power generated by the wind generator. It produces a pure sine-wave and matches that of the grid.
This model
grid-tie has build in bridge rectifier, it has a high voltage protection function, when the wind is too big, and the dump load controlling system can't keep the output voltage from the wind turbine, the controller will disconnect itself from the wind turbine, so it is very safe to be used.
