Off-grid Controller:
It is wind-solar hybrid controller which rectifies AC current generated by wind generator into DC current and charge the battery bank. Unload function will be made when the current caused by the strong wind is much and little current will charge the battery. The controller braked when the batteries are full (batteries get to 125% voltage) and recover to charge reduce to 108% voltage. Manual brake button forces to stop the wind turbine according to circumstance.
