Micro Wind Grid Tie Inverter
Product Description
Micro Wind Grid tie Inverter for 300W~2000W
-speical make for low voltage wind turbine
Introduction
Wind grid connected inverter is the second generation of grid connected inverter. It is widely used in wind turbine system. Senwei's wind grid connected inverter can take immediate actions with wind or solar power. With the function of on grid inverter, the grid connected inverter needn't battery, saving cost and dominating spoilage.

Ø Build In High Wind Protection
Preface
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 and dump load controller, it can maintain the rotating speed of the wind turbine and keep the voltage from the wind turbine always at the range of the rated range of the grid tie inverter. It also 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.
Layout
There are 5 terminals on the left side of the inverter, 3 red terminals will be connected to the three phase output from the wind turbine,and2blackterminals will be connected to dump load resistors. There are 4 LED indicators, 3 green indicators and 1 red indicator, 3 green LED indicators will start to cycle from left to right when the grid and AC input supply is detected.
This indicates the inverter is operating under normal condition.The rate of the cycling is according to how much power is being output from the wind turbine. The bigger the output power is, the faster the rate is. If there is no AC grid detected,the red LED will be on, the inverter will not put out power,this is called"Island Protection".
