Look at your wind charts for your area. You need an average wind of 10 mph if you want to produce meaningful power.
Usually, a mix of sun and wind power does a good job.
Unless you have to have 12 volts for some reason, I would suggest using 48 or 24 volts in the RE system. Since you have a 12 vac wind turbine, you could take the power through a transformer or use a switching power supply to get the voltage higher in order to transport it to the batteries/inverter.
