Off Grid Wind Turbine System

Off Grid Wind Turbine System

The Off Grid Wind Turbine System, developed by Jinan Deming Power Equipment Co., Ltd, is a reliable and efficient solution for harnessing wind energy in harsh and extreme environments. It consists of a wind turbine, off grid controller, battery, solar panels, off grid inverter, metering device, and power distribution system.

Wind Turbine

• High standard, quality components designed for use in harsh and extreme environments.


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


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


• High efficiency and low mechanical resistance energy loss.


• Excellent heat dissipation due to the aluminium alloy outer frame and special internal structure.


• High strength from the fully heat-treated aluminium, providing anti-corrosion and weatherproof properties.


• Generator designed using special material and treated to resist corrosion and oxidation.


• Designed for reliable and long operational lifetime under long-term full output.


• Patent protected design ensuring uniqueness and innovation.


• Designed for a 20-year operational life, providing long-term energy generation.

With the Off Grid Wind Turbine System, wind energy is efficiently converted into AC electrical energy by the wind turbine. The off grid controller then converts it into battery power, which is further converted into AC electrical energy of the same frequency and phase as the grid by the off grid inverter. This system allows for the supply of power to local loads, ensuring a reliable and sustainable energy source.

Product Description

Off-Grid PWM Wind Turbine Controller

FKJ-B Model

Product Characteristics

1. The Off-Grid PWM Wind Turbine Controller is manufactured according to the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard, meeting users' technical requirements.


2. It features 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. The controller offers two sets of control systems: PWM constant voltage system and three-phase dump load system.


4. In strong or super-strong wind conditions, the PWM control ensures constant voltage and current for battery charging from the wind turbine.


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. The controller provides protection functions for the battery, including polarity reverse protection, disconnection, and damage protection.


7. It also offers over-charging protection for the battery. When the battery is full, the three-phase dump load system works, and the wind turbine brakes and stops charging the battery.


8. The controller supports auto recharging of the battery. When the battery voltage reduces to 108% of the rated voltage, it stops the three-phase dump load system to recharge the battery automatically.


9. For manual control, the controller is equipped with a brake switch that activates the three-phase dump load system forcibly.


10. Inside the controller, there is a surge arrester to protect the wind turbine from overvoltage and conduct strong lightning current into the earth to avoid equipment damage.

Solar panel control system is optional based on customers' requirement. Diesel generator port is optional to control the generator start and stop automatically.

The controller adopts Modbus Communication protocol, allowing for convenient secondary development. It also supports adjusting the technical specification via RS485, making it easy to adjust different wind turbines for professional customers.

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 on mobile devices.

For different wind turbines, the controller can be equipped with mechanical yawing, rotate tail control, furled empennage, mechanical brake, hydraulic brake, electromagnetism brake, and other brake functions.

Off Grid Inverter Function Introduction:

1. The Off Grid Inverter uses IGBT from Mitsubishi or Infineon company as the power components.


2. It utilizes an American ATEMEL company microprocessor as a figure controller.


3. The inverter offers perfect protection and warning functions.


4. The circuit frame is compact, with a maximum efficiency of ≥94%.


5. It has a wide input voltage range.


6. RS232/485 communication is supported, and multiple communication interfaces can be selected.


7. It features a big-screen English LCD or LED display, providing a perfect and user-friendly interface.
