    FAQS

    Q1 What problem does GT-PCTC controller solve?
    Compared with PV grid-tied inverters, small wind turbine grid-tied inverters market supply have following problem:
    • Few professional small wind turbine grid-tied invertor factories
    • Small wind turbine grid-tied invertors are several times more expensive than PV inverters
    • Quality is unstable, no after-sale service
    • Low efficiency
    • No grid connection certification
    GREEF GT-PCTC series controller can works together with GROWATT, DEYE, SOLIS brand PV grid-tied inverter, track and control the grid-tied power all the time. User can setting the wind turbine working power curve by themselves on the screen according to the wind turbine performance. It can inspection the generator speed and according to the setting power curve speed VS power to let the invertor working accordingly.
    Q2 How does the PWM and Dump Load protection system work?
    PWM Constant voltage + Three-phase dump load brake:
    • PWM constant voltage is control the wind turbine output not exceed 120% of the wind turbine rated power.
    • If exceeding of PWM’s capacity, it means the wind turbine is over speed, then the three-phase dump load system will brake the wind turbine automatically & immediately. After 10-20 minutes, the brake will release, then the wind turbine will re-start to generation power.
    Q3 How does the controller handle strong winds and grid cut-offs?
    • When meet strong wind, the controller can conduct constant voltage output to ensure the inverter safety running.
    • When grid-tied inverter disconnected, the controller can conduct constant voltage output and wait for inverter resumption.
    • When the grid is cut off, the three-phase dump load will automatically start to brake the wind turbine and let the inverter stop output to grid. When the grid recover, the controller will also recover the wind turbine.
    Q4 How about other built-in protection and control functions?
    • Surge protector: Limit the transient over-voltage that breaks into the wind turbine's power line to a voltage range that the equipment can withstand, or discharge a powerful lightning current into the ground to protect the equipment from lightning strikes.
    • 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 (three-phase dump load).
    • Manual Brake switch: To using this switch, the wind turbine will brake all the time (three-phase dump load).
    Q5 What other optional functions are available for communication and monitoring?
    • Modbus Communication protocol is available. Convenient to carry out the secondary development.
    • RS485 is available. Adjusting the technical specification via RS485.
    • Support WIFI and LAN remote monitoring and control. Customers can monitor the real-time working state of the on grid wind power system via PC and mobile and query history working state. Both Android and OS are compatible in Mobile.
