Discription Our wind turbine controller can be on gird or separate. This autocontroller with a beautiful apperance,simplify indication,easy operation,has an auto-protection function in case of battery converse connection;autoshunt in case of heavy wind(unload). The wind turbine shut down automatically when the battery group volatge gets to 125%; and startup automatically when the voltage drops to 108%. The key component adopts the high-efficient chip control,the complete machines is intelligent. This system is running safely,steadily, and reliably, working efficiently, and have a long life, which is proved by a large number of experiments.
