This depends on the starting wind speed and working wind speed of your wind turbine, which are both listed in the manual.
Starting the wind speed means that when the wind speed is high, the fan will generate electricity when it rotates (it will still rotate even if it is turned slowly, but there will be no electricity. This is not explained), but this amount of electricity must be very high. Less (because it is not rated wind speed), the normal is 1.8 meters/second (starting wind speed).
The rated wind speed means that the fan can work normally when the wind is at least high (this is very simple, everyone knows it), the normal speed is 3-6 meters/second
Because Each manufacturer designs fans differently, so its start-up and rated wind speed are also different. Please read the instructions.
Will the battery be full when the wind power generation stops?
Yes, but it is not so stable. The output voltage will change with the wind. When the wind is strong, the voltage will be high. , when the wind is low and the voltage is low, it is okay if the electrical appliances used do not have high voltage requirements, but not for electrical appliances (such as computers) that require high voltages. If you still use them, there will be Damage to electrical appliances! You should pay attention to this!
To answer your additional questions: First of all, the premise of voltage and current stabilization is that voltage stabilization can only be achieved when the power supply is large enough! When the power generated by wind power is not enough (the wind is low), the voltage cannot be stabilized! The stability of wind power generation is not so continuous! Even if a voltage and flow stabilizing device is added, the effect is still not satisfactory! The voltage and current stability of the intermediate link of the battery is the best, so it’s better not to remove it! It can be used when the wind power is insufficient (when the wind is low), and the insufficient power can be temporarily provided by the battery
No.
Wind turbines mainly rely on natural wind to drive the generator. Only when the wind blows the fan blades will move, the wind turbine will store electricity. If the generator When it stops working, there is no wind. It's not that the battery is full.
