Wind Turbine Charge Controller IP67 Waterproof Size 12V Description This wind turbine charge controller is designed for small wind power systems to improve charging efficiency and protect batteries and turbines. It uses MPPT boost charging to start at low wind speeds and increase energy harvest. The unit is sealed with heat conductive silicone for long term resistance to water, dust, and oxidation. Key benefits Improved charging efficiency: MPPT boost charging converts low voltage from light breeze startup into usable charge, increasing overall energy harvest compared to traditional PWM controllers. Durable and weather resistant: IP67 protection grade with silicone filling provides dustproof, waterproof, and oxidation resistant sealing for reliable outdoor use. Comprehensive protection: Built in overcharge protection, reverse connection protection, short circuit protection, and temperature protection keep battery and system components safe. Manual braking option: A dedicated thin red wire allows manual braking when needed, offering simple control over turbine operation. Flexible compatibility: Supports 12V, 24V, and 48V battery systems when used within rated parameters. Specifications Size: 12V variant Rated battery voltage: 12V, 24V, 48V Wind generator braking voltage: 60V Wind generator recover voltage: 54V Protection class: IP67 Sealing material: Heat conductive silicone filling for waterproofing and anti oxidation Protection functions: Overcharge protection, reverse connection protection, short circuit protection, temperature protection Package contents 1x Wind Turbine Controller IP67 Waterproof 1x Controller manual Wiring and installation 1. Connect battery positive and negative to the controller battery terminals using correct polarity. 2. Connect the wind turbine three phase output to the controller three phase input terminals. 3. For manual braking, short the thin red wire to the positive battery terminal to engage braking. Remove the short to cancel manual braking. 4. Verify connections before powering on and follow the included manual for torque and cable specifications. Performance notes MPPT boost mode helps the turbine generate usable charge even at low RPM, addressing the common issue of slow fan speed failing to charge the battery. The controller applies braking when generator voltage reaches 60V and releases braking when voltage drops to 54V to protect the generator and battery. Suitable for most small off grid wind turbine setups that match the rated voltages and three phase output connection. Typical applications Off grid cabin or remote power supply where wind energy supplements battery charging for lights, communications, and small appliances. Marine or coastal installations with exposure to weather, where IP67 sealing and corrosion resistance are required. Hybrid renewable systems combining wind and solar, where efficient low wind charging increases overall system yield. Compatibility and safety Compatible with battery banks rated 12V, 24V, or 48V when wired and configured correctly. Intended for use with three phase AC output wind turbines that match the controller input specifications. Always follow the manual for correct wiring, fuse protection, and grounding. Ensure the system voltage and wiring are appropriate for the selected battery voltage. This controller provides a practical solution to convert variable wind generator output into reliable battery charging while offering robust environmental protection and essential system safeguards.
