Depending on your location, you will need to choose a HAWT or a VAWT.
A HAWT (Horizontal Axial Wind Turbine) is best suited for turbulent, low speed winds. But they don't produce as much as the VAWT's.
A VAWT (Vertical Axial Wind Turbine) are best suited for large open flat lands with little or no obstructions. They need straight moving air.
Downside to a HAWT is that they produce less power. Upside is they can be placed in many locations at lower heights. They also can handle higher winds (like storm gusts) as there is no swinging back and forth. They are easier to lock in place, too.
Downside to a VAWT is that need height, the higher the better, and they need lots of space to keep the air from being turbulent. High speed winds are their enemy. You would need to get one with a very good locking mechanism to keep the blades from spinning in stormy weather.
As far as charge controllers go, you need a controller that is designed for wind turbines as they have a dump load connection. This is for when the batteries are full, the power generated can be offloaded somewhere. Turbines (both wind and hydro) need a dump load. They will burn themselves up if they don't have a dump load.
