EEB1 10KW PWM Wind/Solar Hybrid Controller Off-grid

EEB1 10KW with two sets of control systems:PWM constant voltage system and three-phase dump load system. Big LCD shows 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, history data can be saved for 30 days)

EEB1 10KW PWM Wind/Solar Hybrid Controller Off-grid


Off-grid Connection


Features


     ◆ The 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, history data 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.
