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 2 pcs resistor cable Feature 1.Boost charge: Flexible independent step-up circuits. Wind turbine charging mode is MPPT and Solar panel charging mode is PWM. 2.Battery type: Lithium Battery can be connected with this controller. Inluding all other battery type. 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.） The controller battery voltage is 12/24V/48V. Especially is wind turbine adopts booster MPPT technology which make charge continuous and efficiently even in low wind speed. It can connect DC Load with 3 working models. The cable entry is well made to connect. Make the system wiring is simple and easy to operate. Big&Clear Display The new screen is bigger and clearer. Easy for you to browse in any angle. Four operation buttons, convenient for user to understand and handle. Updated Intelligent system The parameters will be set well automatically after connect battery. The Upgraded sofeware system can control voltage more stable to avoid burn battery. 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. 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 is used for GEL ,lead-acid and lithium battery.
