3kW solar wind hybrid controller for hybrid system on grid ZKJ-GT

Model Number: ZKJ-GT3KW Brand Name: ZONHAN Key Specifications/Special Features: ZKJ-GT (Grid-tie) model product characteristics:◆Product is manufactured according the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard also with users’ technical requirements◆Two sets of control systems: PWM constant voltage system and three-phase dump load system◆PWM constant voltage control is 120% of the rated power of the wind turbine. In case exceeding of PWM’s capacity, the three-phase dump load will automatically start immediately. After 10-20 minutes, the three-phase dump load will stop and the wind turbine will re-start to resume power supply to ensure the safe running of the overall wind turbine generation system◆Under the strong or super-strong wind conditions, the controller can conduct constant voltage output to ensure the inverter safety running◆Under the condition of disconnected grid-connected inverter, the controller can conduct constant voltage output and wait for inverter resumption◆Three-phase dump load of the controller will automatically start and the inverter will stop grid output when the power grid is offAs soon as the grid power resuming, the controller stops three-phase dump load and the inverter will resume power supply◆For the different wind turbine generator type, the controller can be equipped with mechanical yawing, furled empennage, mechanical or hydraulic, pneumatic, electric magnetic and other brake functions Technical parameters of the ZKJ-GT model grid-tie wind turbine controller Type 3KW Function rectifier ,control Operating environment Temperature-30-40℃,humidity≤80% PWM constant pressure voltage ≥380Vdc 3-phase load voltage of the wind turbine 410±5Vdc Time-lapse of the wind turbine 3-phase load 12-20 min Low-voltage ≤200Vdc PWM Fuse 10A Fuse of DC output 16A Size of the controller 480*360*230 mm Weight of the controller 21 Kg Size of the load 660*320*320 mm Weight of the load 19 Kg
