Information

The wind generator charge controller is an intelligent controller specially designed for wind power generation systems. Making full use of wind energy resources to generate electricity, the equipment not only can efficiently convert the electric energy generated by the wind turbine to charge the battery, but also provides powerful control functions.

MPPT wind generator charge controller

The wind generator charge controller regulates and controls the electric energy generated by the wind generator. On the one hand, the adjusted energy is sent to the DC load or AC load, and on the other hand, the excess energy is charged to the battery pack according to the characteristic curve of the battery. , When the generated electricity can not meet the needs of the load, the controller sends the electric energy of the battery to the load. After the battery is fully charged, the controller must control the battery not to be overcharged. When the stored electric energy of the battery is discharged, the controller should control the battery not to be over-discharged to protect the battery.

The wind generator charge controller adopts PWM stepless unloading method to control the fan to charge the battery intelligently. When the electric energy generated by the wind turbine exceeds the storage capacity of the battery, the control system must consume the excess energy. The common control method is to connect the entire unloading. At this time, the battery is generally not full, but all the energy is consumed in the unloading, which causes a waste of energy. Others use staged connection and unloading. The more stages, the better the control effect, but generally it can only achieve about five or six levels, so the effect is still not ideal. The best control method is to use PWM (Pulse Width Modulation) method for stepless unloading, which can reach thousands of unloading. Therefore, under normal unloading conditions, it can ensure that the battery voltage is always stable at the float voltage point, but only the excess electric energy is released to the unloading. So as to ensure the best battery charging characteristics, so that the electric energy can be fully utilized.
