Compact wind turbine charge controller with MPPT BOOST charging for improved lowwind performance and reliable battery charging. Designed for home and small offgrid systems, this controller increases charging efficiency compared with conventional PWM controllers and supports 12V and 24V battery systems automatically. Key features MPPT BOOST charging technology: starts and supplies power in light wind and low voltage conditions to improve charging when turbine RPM is low. Robust sealed construction: filled and sealed with thermally conductive silicone material and thermal filler for dustproof and waterproof protection rated IP67. Multiple protection functions: builtin protection against overcharge, reverse connection, short circuit, and temperature. Simple operation: plug and play style connections with automatic 12V and 24V detection; no complex configuration required. Wide compatibility: works with most small wind turbines and supports generator power ratings up to 800W. Technical specifications Maximum input AC voltage: AC 35V Output DC voltage: DC 12V or 24V (automatic) Battery charge cutoff voltage: DC 14.5V plus or minus 0.3V for 12V, 29V plus or minus 0.3V for 24V Maximum charging current: 15A at 12V, 10A at 24V Generator limit voltage: 14.5V plus or minus 0.3V or 29V plus or minus 0.3V Protection level: IP67 Static power consumption: 0.008A Supported generator power: 500W and 800W Maximum wind rating: level 12 Operating temperature range: 35C to 65C Input wiring: threewire Control mode: compatible with 12V and 24V systems Installation: bolt fixed Wiring and installation notes 1. Confirm the turbine output voltage matches the battery rated voltage before connecting. 2. First connect the positive and negative terminals of the battery to the controller. 3. Then connect the threephase output of the wind turbine to the threephase input terminals on the controller. 4. Use the bolt fixed mounting points for secure installation. Package contents 1 x Wind power controller Recommended applications Small offgrid cabins and cottages where wind complements solar to maintain battery charge during low sunlight. Remote monitoring stations and telecom sites that require reliable charging in variable wind conditions. Rural or farm power systems and small boats using 12V or 24V battery banks that need improved lowwind charging performance. Precautions Verify fan or turbine output voltage is consistent with the battery system before installation. Always connect the battery first, then the turbine threephase output. Follow wiring instructions carefully to avoid damaging the controller. Product color and dimensions may vary slightly due to lighting and manual measurement tolerances.
