Feature:1. [MPPT Technology] Ensures that the wind generator can still charge the battery at low wind speeds and low rotation, improving the power utilization by 90%.2. [Automatic Matching] This wind generator controller can automatically match 12V or 24V battery, controlling voltage and current limit during charging to ensure best battery charging.3. [Comprehensive Preservation] This wind turbine controller features overcharging, over discharge, reverse connection, overload preservation, supports auto braking or manual braking.4. [Effective Heat Dissipation] Deep cooling wind tunnel rapidly dissipates heat, solving the cooling problem of controller during high current charging, ensuring safe, stable operation.5. [IP67 Design] The wind turbine controller uses thermal silicone potting for sealing, making it waterproof, dustproof, and circuit oxidation resistant.Specification:Item Type: MPPT Wind Turbine ControllerMaterial: Aluminum AlloyRated Voltage: 12V 24VCharging Mode: MPPTWind Generator Braking Voltage: 14.5V 29VWind Generator Recovery Voltage: 13.5V 27VIP Rating: IP67Display: Diode Indicator.Package List:1 x MPPT Wind Turbine Controller
