Zhuhai Sunray Meter & Control Technology Co., Ltd., Established in 2006, it has been engaged in the development and production of all kinds of static AC and DC electricity meters(kwh meters) with different installations such as wall-mounted, DIN rail mounted, Panel mounting and with different meters' functions, is one of the earliest domestic enterprises producing DC watt-hour meter in China. At present, our DC meters are mainly used for electric vehicle(EV) charging piles, charging stations, solar photovoltaic (PV) power generation, electric energy storage power stations, mobile communication base stations, etc., and the meters can also be used in the fields of DC display screen and subway, etc, all DC electric energy is applied. At the same time, our DIN rail AC electric energy meters(kwh meters) are also used for AC power monitoring.

Now the company focuses on new applications of our meters in new energy industry, We provide all static AD and DC meters, AC and DC supervision system solutions, We are integrator of the electric vehicle charging pile, electric vehicle charging station and system solutions. We are also integrator of solar photovoltaic components, solar photovoltaic stations solutions.

The main products are as below,
