Profile: Huangya Energy Technology Inc. is a manufacturer of wind turbine generators and energy equipments. We design, produce & sell 300 watt to 20 KW wind turbine generators, small wind turbines, solar hybrid generator system, solar power electrical system, grid off & grid on (grid tie) inverter, wind & solar charging controllers, converter, micro-hydropower and system solutions. Our wind/solar off-grid power system consists of wind turbine/solar panels, microprocessor controller, battery and inverter. It is widely used in off electric area away from the public power network such as outlying country, a pasturing area, island, and plateau. It provides power for communication relay station, weather power station and hydrographic monitoring. Wind/solar on-grid power system consists of wind turbine/solar panels, a system controller and inverter. Solar panels produce DC (direct current) electricity, and this electricity runs though the converter & inverter to produce AC (alternating current) electricity. These grid solar power systems enjoy the advantages of battery-free and low cost. Our wind turbine generators are manufactured in accordance with various national and international standards.
