China's CSR Zhuzhou Electric Locomotive Research Institute Co., Ltd. (referred to as China CSR Zhuzhou) developed 500 kilowatts of new PV inverter PV power station in Qinghai Plateau successfully installed a grid. According to reports, a move that the company is fully capable of photovoltaic products, large-scale photovoltaic power plants to meet the complex requirements of grid access conditions, with volume production conditions.

Reporters learned that the success of the new grid inverter 500 kilowatts and 500 kilowatts inverters compared to the original, the whole cost of significantly reducing the volume reduced by 20%, conversion efficiency, longer life, harmonics in the system, the application of voltage range, active and reactive power adjustable, adaptive grid phase sequence, night SVG reactive power compensation and other key performance indicators than similar products. The indicators in full compliance with the national grid and the Golden Sun certification standards, the overall performance reached the advanced level of similar foreign products.

PV inverter is the core equipment of solar photovoltaic power plant, one of the solar photovoltaic systems, solar cell modules is converted to DC by means of energy through photovoltaic inverter power conversion and control system of direct current into grid electricity to meet quality requirements AC. In this process, the inverter assume orthogonal transformation function, but also has to maximize solar cell performance and system protection features in the industry, inverters known as "PV's core", it shows in the photovoltaic industry chain equipment technology and the importance of position.

At present, China PV inverters especially high-power photovoltaic inverter in its infancy, there are dozens of domestic enterprises engaged in research and development of this product, but a late start, foundation is weak.

China CSR Zhuzhou is the field of rail transportation variable flow control technology and industrial leader converter technology is also China National Engineering Research Center of the only support unit. 2009, the company relies on the technology and industrialization, engineering advantages, strong entry photovoltaic field. Four years, the company has independently developed ranging from 50 kW to 1 MW power level of more than 10 kinds of inverters and related facilities, becoming one of the few domestic product spectrum series, full of the enterprises.

Right now, China has made CSR Zhuzhou "Golden Sun", CE and many other industry qualifications, has awarded more than 50 domestic 19 provinces PV projects with a cumulative capacity exceeded 500 MW. According to statistics, the first half of 2013, the company installed capacity to enter the top five national industry, a national master key independent photovoltaic device technology innovation-oriented enterprises.
