1. High-quality technical components for stability and reliability.2. Voltage/current controlled charging ensures that the batteries are always in the best charging condition.3. MPPT charging efficiently collects energy from the generator to charge the batteries.4. Aluminum alloy shell makes it lightweight and provides good heat dissipation. Waterproof and dustproof shell makes it usable in various outdoor environments.5. Full protection: overcharge, overdischarge, reverse connection of batteries, overload, lightning, current control, automatic wind generator.1. Safety instructionsPLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR USING THIS PRODUCT.1.1 Make sure that the wind generator's output voltage matches the battery's rated voltage.1.2 First connect the battery's positive and negative cables, then the wind generator's three cables.1.3 Make sure you connect the battery and wind generator to the controller according to these instructions. Reverse polarity or incorrect connection can result in abnormal operation of the system or damage to system components.2. Wiring2.1 Connect the battery's \"+\" and \"-\" to the controller's red and black input cables.2.2 Connect the wind generator's three cables to the controller's three blue cables.3. Lights3.1 When the wind generator light (green) is on, it indicates that the wind generator connection is normal and it shows the wind generator's speed with speed.3.2 When the brake light (red) is on, it indicates that the controller is automatically shut off due to the battery being fully charged or the controller's overcurrent protection function being activated.Type: 1000Wsize: 100 x 85 x 25mmMaterial:Aluminum alloycolor: black+orangePackage contents:1 x Wind turbine controllerOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
