Unloading function In the high wind speed or the wind generator power beyond the scope of the battery capacity, the controller launches the unloading function by dump load resistor, protect the controller and battery. 1 pc controller 1 pc dump load resistor 1 pc operation Manual 2 pcs MC4 wrench Feature 1.Control mode: wind turbine generator mode is MPPT charge function, solar panel mode is PWM. 2.Boost charge: Flexible independent step-up circuit(optional) 3.Protection: Reversed charging Protection of solar, over charge voltage/under voltage & Over load voltage Protection, battery reverse connects and open circuit protection, Lightning Protection, etc.） This controller can recognize battery voltage 12/24V auto. It can connect two DC Load with 4 working models. Especially is wind turbine charging having MPPT The cable entry is well made to connect. Make the system wiring is simple and easy to operate. Big LCD Display Which convenient to browse parameters. Including solar panel, wind turbine, battery and load status. And four operation buttons, easy for user to understand and handle. Good Heat Dissipation Aluminum profile not only sturdy and durable, but also with good heat dissipation performance. Which can make hybrid controller self-cooling by itself. Well Packing &Clear Manual Customized foam packaging to ensure the safety of transportation. Clear and profession manual which make you to use wind and solar controller well and easy. Note: 1. Correct connection sequence: 1) pls connect the wires between battery and controller 2) pls connect the wires between wind/solar panels and controller 2. Usable battery: This model only used for GEL and lead-acid battery.If you will connect lithium battery，please buy our upgrade hybrid controller.
