MPPT Wind Controller for Small Wind Generators Overview This MPPT wind controller maximizes charging efficiency for small wind generators, maintaining battery charging even at low wind speeds and low rotor speeds. Built with an aluminum alloy housing and IP67 sealing, it offers reliable performance, automatic battery voltage matching, and multiple protections for safe operation. Key benefits Higher energy capture: MPPT technology improves power utilization by up to 90, enabling charging at lower wind speeds and slower rotations. Plug and play compatibility: Automatically detects and adapts to 12V or 24V battery systems, regulating voltage and current to optimize battery charging. Builtin protection suite: Prevents overcharging, overdischarge, reverse connection, and overload. Supports both automatic braking and manual braking of the wind generator. Reliable thermal management: Deep cooling wind tunnel design rapidly dissipates heat during current charging to maintain stable operation. Robust weather resistance: IP67rated with thermal silicone potting for sealing, making the controller waterproof, dustproof, and resistant to circuit oxidation. Simple status feedback: Diode indicator display provides clear charging and fault status information. Specifications Item type: MPPT Wind Controller Material: Aluminum alloy Rated voltage: 12V and 24V Charging mode: MPPT Wind generator braking voltage: 14.5V (12V system) and 29V (24V system) Wind generator recovery voltage: 13.5V (12V system) and 27V (24V system) IP rating: IP67 Display: Diode indicator How it solves problems Low wind performance: MPPT tracking converts variable wind input into the most effective charging power, so the battery keeps charging even in light wind. Battery longevity and safety: Automatic voltage matching and controlled charge current reduce the chance of incorrect charging and help preserve battery life. Overheating avoidance: The integrated cooling tunnel prevents thermal buildup during heavy charging, avoiding operational interruptions. Outdoor durability: IP67 sealing and potting protect internal electronics from moisture, dust, and oxidation for longterm field use. Typical applications Offgrid cabins and remote homes: Charge 12V or 24V battery banks from a small wind turbine to support lighting, appliances, and charging. Marine and RV installations: Maintain battery state of charge on sailboats or recreational vehicles where space limits system size and conditions vary. Remote equipment and monitoring sites: Power batterybacked sensors, communication gear, or pumps in locations without reliable grid access. Wiring instructions 1.
