Why does our Mini Wind Turbine not need a charge controller?

One of the best features of our 12 volt Mini Wind Turbine is that it doesn't need a charge controller to function. 

The answer to this question depends on 2 variables: The wind speed and the size of your battery. 

Here is our official recommendation:

With no charge controller, in order for your battery to not be damaged, the battery should have at least 50 Amp-hours (Ah) for every 2 watts the turbine is producing. This rule of thumb also works for solar panels.

Here's an example:

You're at the beach.  The wind speed is about 25 mph and the mini wind turbine is producing about 10W.

10W / 2W = 5

5 x 50 = 250 Ah

This means that if your battery is rated for at least 250 Ah, you don't need a charge controller. 

As you can see, everyone's situation is different. If you would like to use a charge controller with your mini wind turbine, we would recommend our 120W max charge controller

 As always, please don't hesitate to email us at Sales@CuttingEdgePower.com with any questions or concerns you may have.

    If mounted on a vehicle and the travel speed is 60 mph, what would be the produced wattage?
