Product Name: 20kw 30kw Wind Solar Diesel off Grid Controller Certification: CE Transport Package: Polywood Case Origin: China Product Description Off-Grid PWM Wind Solar Hybrid Controlleroff grid PWM wind solar hybrid controller Product CharacteristicsThe 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,power;solar panel voltage,current,power;battery group voltage, charge current.(The main board is with button battery,in case of power failure, historydata can be saved for 30 days)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 to ensure safe running of the overall wind turbine system.When the strong or super-strong wind conditions PWM control to ensure battery charged by the wind turbine with constant voltage and current.When the battery disconnect or damage, the three-phase dump load will start automatically to avoid the wind turbine idling and runaway accident.The protection function of battery: polarity reverse protection, disconnection and damage protection.Over-charging protection of the battery: When the battery is full (the battery voltage getting 125% of the rated voltage), the controller will carry out three-phase dump load automatically to stop charging the battery.Auto recharging of battery: When the battery voltage reduces to 108% of the rated voltage,it stops three-phase dump load to recharge battery automatically.The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will carry out three-phase dump load forcibly.The inside of the controller is equipped with surge arrester. Contain the over voltage into the wind turbine under the bearable voltage of the equipment or system. On the other way, to conduct the strong lightening current into the earth directly to avoid any damage of equipment.Solar panel control system is optional.based on customers' requirement. Diselgeneratorportisoptional.ControlthegeneratorstartandstopautomaticallyAdopt 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.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.*Above parameter only for reference. Could be custom made to user specifications.
