Profile: Ningjin Huaya Industry Co., Ltd. is specialized in offering wind turbine generator. Our products include wind & PV hybrid system, water heating system, wind turbine controller, and tower & wind turbine blades. Wind turbine generators are used primarily for electricity generation. The power can be stored in a battery bank, or connected to the mains supply using a suitable grid tie inverter. We design a special controller for heating water directly. The controller should be powered by two PCS 12V/AH batteries. The controller will charge the batteries automatically when the turbine spins.
