✔ 12V/24V/48V Automatic Match Battery:This wind turbine controller can auto match 12V/24V/48V battery system. Voltage and current limiting are be controlled during recharging to ensure the best charging effect. Meanwhile, it provides the maximum protection to the wind turbine and battery. ✔ Good Heat Dissipation: The wind turbine charge controller is made of aluminium alloy housing with good heat dissipation. ✔ IP67 Waterproof Controller: IP67 protection grade, this wind turbine charge controller is dust-proof, waterproof, oxidation-resistant, durable and wear-resistant. The charge controller can work steadily even in very humid environment. ✔ Automaticity Control:This charge controller can be used for 20000W wind turbine generator. It can control wind generator charge battery automatically. When the battery is fully charged, brake can be taken effect automatically by the interior circuit. When the battery voltage drops to restore voltage level, wind turbine can recover to charge battery automatically. ✔ Wind Turbine Controller LED:When the controller red indicator (BRAKE) is on, the battery is fully charged, the wind turbines is automatically braked, or the brake is automatically activated due to overcurrent protection.
