VWG3008 wind & solar hybrid controller can control PV cells and wind turbines charging battery with an intelligent charge mode. With the appearance of fine and operational running status lights, the controller is easy to operate. Have clear indications and accurately control battery to charge and discharge, with perfect protection. Controller core component adopt the United States original micro-controller, control software using the German scenery complementary advanced control technology. Current limiting constant voltage type charge greatly extending the battery life. Controller has a high charging efficiency, low no-load loss, security, stability, reliability and long life. Has a very high cost performance.

Main function：
* Precise control of digital and intelligent
* Using PWM constant voltage charging mode, always keep batteries in a full state。
* Prevent the battery overcharge. When battery voltage is too high, controller stop to charge the battery. When the battery voltage back to the settings, back to normal charging.
* Prevent the battery over discharge. When the battery voltage drops below than the setting value, the lights tips to prevent over discharge to protect the battery, when battery voltage restored, the lights automatically extinguished.
* Prevent the battery reverse charge to PV cells
* When the DC voltage which rectifier from the three-phase alternating by wind turbine is higher than 150V, the controller will automatically unloading and control the wind turbine brakes, back to normal after continuing to the setting time.
* Wind turbine manual brake protection. Turn the brake switch to “ON” to control the wind turbine brake when requirement.
* Automatic cooling to protect the controller. When the controller temperature is too high the cooling fan will be automatically activated to ensure the normal work of the controller。

Perfect protection：
* Reverse Polarity Protection for Battery
* Reverse Polarity Protection for Solar panels
* Protection from the lightning strike
