FKJ-GT (Grid-tie) model Product Characteristics
The product is manufactured according the JB/T6939.1-2004 industrial standard and GB/T
19115.1-2003 national standard also with users' technical requirements.
Big LCD display. The images tell working state visually. Various data show: real-time wind
turbine voltage, current, solar panel voltage, current, DC output voltage, current, total power
Two sets of control systems:PWM constant voltage system and three-phase dump load
When the strong or super-strong wind conditions, the controller can conduct constant voltage
output to ensure the inverter safety running.
The inside of the controller is equipped with surge protector. Contain the over voltage into
the wind turbine under the bearable voltage of the equipment or system. On another way, to
conduct the strong lightening current into the earth directly to avoid any damage of
The controller is equipped with emergency stop switch; in case of emergency, press down the
emergency stop button in the front panel to cut off all power supply of the controller and the
wind turbine will immediately brake.
The controller is equipped with manual three-phase dump load switch. To using this switch,
the wind turbine will brake.
Adopt Modbus Communication protocol. Convenient to carry out the secondary development.
Adjusting the technical specification via RS485 is available. Convenient to adjust the different wind turbines for professional customers.
Support WIFI and GPRS. Customers can monitor the real-time working state of the on grid wind power system via PC and mobile and query history working sate. Both Android and OS are compatible in Mobile.
Can increase the solar panel control system according to customer requirements.
For the different wind turbine, the controller can be equipped with mechanical yawing, rotate tail control, furled empennage, mechanical brake, hydraulic brake, electromagnetism brake and other brake functions.
