Features The controller can control the wind generator to automatically charge the battery. When the battery is fully charged, the brake can be automatically controlled by the inner circuit. Comprehensive waterproof protection. If the controller is not waterproof, but is used in a light mud water environment or the moisture is high, the controller can easily corrode and be damaged. Unique reverse connect protection circuit. In case of improper operation, plus and minus of the battery do not need to be replaced, just to reset plus and minus to the right point. This makes the entire system more reliable. The product is made of aluminium alloy material, corrosion resistant and of good quality. When charging, it has the function of limiting voltage and current to ensure the best charging effect. At the same time, it provides maximum protection for wind turbines and batteries.
