What type of controller should I use with Chispito?
Dump load controllers are best with wind generators. Basically, when the batteries get full, they dump the extra energy coming from the wind generator into a dump load, like a water heater. There are many sources and types of these controllers. Do not use an in-line controller, like you would use with a solar panel. These series controllers disconnect the wind generator when the batteries are full, allowing it to free spin and throw parts and blades at your head!
