The battery voltage arrive the floating charging point2. The rated output voltage of the fan is much higher than the rated voltage of the battery, because the fan speed is proportional to the output voltage, and the fan voltage is dragged by the battery and will not be very high, so the speed will be very low3. The unloading tube was

[Stable Performance] Automatically match wind turbines charging, using supercharged MPPT technology, at low wind speeds, wind turbines power can still be used.

[MPPT Boost ] MPPT and boost charging, high efficiency tracking chip can effectively improve the charging efficiency of wind turbines, solar and wind energy, while charging and using electricity at the same time.
