The Wind Generator will generate power from the alternator and from there produce AC electricity.
It is able to charge 12V batteries after connecting to a rectifier or charge controller.
If your home or farm is connected to the power grid, on windier days you may be able to sell excess power generated by your wind turbine to your utility.
At other times when the turbine cannot generate all the power you need, you would buy power from the grid.
Even if net metering is unavailable, you might be able to reduce your power bills by using the electricity generated by wind turbines, and become less dependent on your utility.
