Product Description

Product Description

Off Grid Wind Turbine System

The Off Grid Wind Turbine System, manufactured by Jinan Deming Power Equipment Co., Ltd, is a reliable and efficient solution for harnessing wind energy in off-grid applications. This system is composed of various components including a wind turbine, off-grid controller, battery, solar panels, off-grid inverter, metering device, and power distribution system.

Wind Turbine Features:

1. High standard, quality components designed for harsh and extreme environments.


2. Equipped with an electric brake and overcharging protection for safe operation.


3. Low wind speed model with stable output voltage and a charge controller.


4. High efficiency and low mechanical resistance energy loss.


5. Excellent heat dissipation thanks to the aluminium alloy outer frame and special internal structure.


6. Constructed with fully heat-treated aluminium for high strength, anti-corrosion, and weatherproofing.


7. Generator designed with special materials to resist corrosion and oxidation.


8. Reliable and long operational lifetime under long-term full output.


9. Designed for a 20-year operational life.


10. Patent protected design.

The wind turbine in this system converts wind energy into AC electrical energy, which is then stored in the battery through the off-grid controller. The DC electrical energy is further converted into AC electrical energy of the same frequency and phase as the grid by the off-grid inverter. This system also supplies power to the local load, making it a comprehensive and efficient off-grid solution.

Product Description

Off-Grid PWM Wind Turbine Controller

FKJ-B Model

Product Characteristics:

1. The product is manufactured according to the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard, meeting users' technical requirements.


2. Equipped with a big LCD display that visually shows the working state and various data, including real-time wind turbine voltage, current, power; solar panel voltage, current, power; and battery group voltage, charge current.


3. Features two sets of control systems: PWM constant voltage system and three-phase dump load system.


4. Under strong or super-strong wind conditions, the PWM control ensures the battery is charged by the wind turbine with constant voltage and current.


5. In case of battery disconnect or damage, the three-phase dump load system automatically starts to prevent wind turbine idling and runaway accidents.


6. Includes battery protection functions such as polarity reverse protection, disconnection, and damage protection.


7. Provides over-charging protection for the battery. When the battery is full, the three-phase dump load system activates, causing the wind turbine to brake and stop charging the battery.


8. Supports auto recharging of the battery. When the battery voltage reduces to 108% of the rated voltage, the three-phase dump load stops to automatically recharge the battery.


9. Equipped with a manual brake switch for forcibly carrying out three-phase dump load.


10. Includes a surge arrester inside the controller to protect against overvoltage and lightning currents.


11. Optional solar panel control system based on customers' requirements.


12. Optional diesel generator port for automatic control of generator start and stop.


13. Adopts Modbus Communication protocol for convenient secondary development.


14. Allows adjustment of technical specifications via RS485 for different wind turbines.


15. Supports WIFI and GPRS for real-time monitoring of the on-grid wind power system via PC and mobile devices, with the ability to query history working state. Compatible with both Android and OS in mobile devices.


16. Can be equipped with various brake functions for different wind turbines, such as mechanical yawing, rotate tail control, furled empennage, mechanical brake, hydraulic brake, and electromagnetism brake.

Off Grid Inverter Function Introduction:

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


2. Utilizes American ATEMEL company microprocessor as figure controller.


3. Offers perfect protection and warning functions.


4. Compact circuit frame with a maximum efficiency of ≥94%.


5. Wide input voltage range.


6. RS232/485 communication with multiple communication interface options.


7. Equipped with a big-screen English LCD or LED for perfect display and user-friendly interface.
