1Used to control the wind turbine to charge the battery automatically. When the battery is full, the fan is braked by the internal circuit automatic control. When the battery voltage drops to the recovery voltage, the turbine resumes charging the battery, thus protecting the turbine and the battery. 2Enable voltage and current limits during charging to insure optimum charging performance. At the same time, it offers the greatest protection for wind turbines and batteries. 3Reverse connection protection circuit. Since when the battery is reversed due to improper operation, there is no need to replace the fuse, just reset the positive and negative to the correct position. 4With full sealing comprehensive waterproof design, it can resistant the heavy humidity, salinity, such as ground water operational environment. The protection grade reaches IP67 above, even in water can steadily work normally for a long time. 5Aluminum alloy material,small size, good for heat dissipation. 1000W maximum applicable power, and DC60V maximum voltage, which has stable performance.
