Wind Turbine Controller Size 48V Package contents 1x Wind Turbine Controller 1x Controller manual Key benefits Reliable power management for small to medium wind turbines up to 4000W. Automatic battery voltage detection and adaptive charging for DC 12V, 24V, or 48V systems, improving charging efficiency and reducing setup complexity. MPPT electrodeless and noiseless unloading provides stable turbine control without moving relays, reducing maintenance and audible noise. IP67 rated waterproof housing and wide operating temperature range allow continuous operation in harsh outdoor environments. Main features Rated power: 4000W Compatible battery systems: DC 12V, 24V, 48V (automatic detection and parameter selection) Waterproof level: IP67 Protections: battery overvoltage protection, windgenerator current limit, windgenerator brake, speed protection Unloading method: MPPT electrodeless and noiseless unloading Indicator: LED status indicators for easy system monitoring Operating temperature: 35 C to +75 C Why this controller solves common problems Prevents battery overcharge through automatic voltage detection and overvoltage protection, extending battery life. Limits generator current and applies braking and speed protection to safeguard the turbine from overspeed and excessive mechanical stress. Electrodless MPPT unloading reduces mechanical wear and operating noise compared to relays, lowering maintenance needs. IP67 protection and wide temperature tolerance make it suitable for exposed installations where moisture, dust, or temperature extremes are a concern. Specifications summary Power: 4000W Voltage compatibility: DC12V, DC24V, DC48V (auto detect) Waterproof rating: IP67 Working temperature range: 35 C to +75 C Indicators: LED Protection functions: battery overvoltage protection, windgenerator current limit, windgenerator brake, speed protection Unloading method: MPPT electrodeless and noiseless unloading Wiring and installation steps 1. Connect the battery positive and negative to the controller battery terminals labeled positive and negative. 2. Connect the threephase output of the wind turbine to the threephase input terminal of the controller fan. 3. For manual brake operation, short the thin red wire to the battery positive terminal to engage the brake. Remove the short to release the brake. Note: The controller will automatically detect whether the battery system is 12V, 24V, or 48V and apply the corresponding charging parameters to optimize conversion efficiency. Recommended applications and scenarios Off grid cabins and remote homes: Integrate with a battery bank to store wind energy for lighting and basic appliances where grid power is unavailable. Remote monitoring stations and telecom sites: Provide dependable turbine charge control with reduced maintenance needs due to electrodeless unloading and rugged IP67 protection. Small farms, boat installations, and hybrid renewable systems: Use as part of a wind plus battery setup to maintain battery health and manage turbine output during variable wind conditions. Notes for safe and reliable operation Ensure correct polarity when connecting the battery to avoid damage. Match turbine threephase output wiring to the controller threephase input terminals. Use the manual brake connection only when and ensure secure connections. Follow the included controller manual for detailed installation, mounting, and troubleshooting guidance. This controller provides a practical, durable solution for managing wind turbine charging and protection in 12V, 24V, and 48V battery systems while minimizing mechanical wear and noise through MPPT electrodeless unloading.
