Wind turbine off grid inverter

Wind off-grid power system consists of the wind turbine, controller, battery, wind off grid inverter and distribution system.Wind generate AC power through the wind turbine generator driven by the wind, and then converted to be DC power. The wind turbine off grid inverter will inverte the DC power to be the right voltage , frequency and pure sine wave AC power to the local load. When the wind speed is very hight to cause high dc voltage,  the controller will start beyond full energy by unloading, removing.

Wind turbine off grid inverter

 1. Using IGBT from Mitsubishi or Infineon company as the power components

 2. Using American ATEMEL company microprocessor as figure controller

 3. Perfect protection and warning functions

 4. Circuit frame compact,Max. Efficiency≥92%

 5. With wide input voltage range

 6.RS232/485 communication,multi communication interface can be selected

 7. Big-screen English LCD, perfect display, interface-friendly
