This wind generator charge controller uses MPPT boost charging to improve power harvest from lowspeed wind and keep batteries charging even when the turbine runs slowly. It replaces traditional PWM controllers to increase charging capacity and overall system efficiency while protecting batteries and electronics. Key benefits Starts and charges at low wind speeds: MPPT boost charging and lowvoltage startup let the controller extract usable energy from breezes that would not charge with conventional controllers. Higher charging efficiency: Upgraded MPPT control improves energy conversion and battery charging capacity compared with PWM controllers, making small wind systems more effective. Robust protection and reliability: Builtin overcharge protection, reverse connection protection, short circuit protection, and temperature protection safeguard batteries and turbine components. Durable, weatherresistant construction: IP67rated protection, heat conductive silicone filling and sealing, and oxidationresistant materials provide dust resistance, waterproofing, and longterm durability. Features and specifications Charging method: MPPT boost charging for improved energy capture at varying wind speeds. Lowvoltage start capability: Designed to begin charging even when turbine speed is low. Protections: Overcharge protection, reverse connection protection, short circuit protection, temperature protection. Environmental resistance: IP67 protection grade with heat conductive silicone filling to prevent moisture ingress, dust accumulation, and circuit oxidation. Materials and durability: Oxidationresistant and wearresistant construction for outdoor use. Performance: Optimized to increase conversion rates and make small wind generation systems more practical and reliable. Compatibility and applications Designed for use with small wind turbines and batterybased offgrid power systems. Suitable for integration with 12 V and 24 V battery banks when matched to turbine and battery specifications. Use with chargeable battery types commonly deployed in small wind systems; verify battery compatibility and system wiring before installation. Practical use scenarios Remote cabin or offgrid shed: Charge a battery bank from a small wind turbine to power lights, pumps, and lowvoltage appliances during windy conditions and breezy nights. Marine and coastal installations: Provide reliable battery charging aboard small boats or shoreside equipment where salt air and moisture demand corrosionresistant, waterproof electronics. Rural telecommunications or sensor sites: Keep batteries topped up for remote monitoring equipment or weather stations where steady wind may be intermittent and lowspeed startup is required. Installation notes Confirm system voltage and battery type compatibility before connecting. Follow correct polarity when wiring to avoid activating reverse connection protection. Place the controller in a location that allows heat dissipation while remaining protected from direct water exposure, even though the unit is sealed for outdoor use. This controller is a practical upgrade for small wind generation systems that need improved lowspeed charging performance, enhanced protection, and weatherresistant construction.
