Off-grid Controller
Wind-solar hybrid controller which rectifies AC current generated by wind generator into DC current and charges the battery bank. Unload function activates when strong wind produces excess current. The controller brakes when batteries reach full capacity (125% voltage) and resumes charging when voltage reduces to 108%. Includes manual brake button for emergency stops.
