my country South Locomotive's photovoltaic grid-connected inverter passed the low voltage ride-through certification

Recently, CSR GTI-500 photovoltaic inverter successfully passed the ride-through test at the State Grid Electric Power Research Institute in Nanjing and received unanimous praise from the testing agency.

What is "low voltage ride-through"? When a grid fault causes a voltage drop, if the photovoltaic power station is also immediately cut off, it will cause drastic changes in the entire system, resulting in a large-scale power outage. Low voltage ride-through means that when such a problem occurs in the power system, the photovoltaic power station can remain connected to the grid and support the grid fault recovery, thereby "riding through" this low voltage period and avoiding the expansion of the grid fault.

According to the requirements of the National Energy Administration and the State Grid Corporation for grid-connected photovoltaic power stations, all photovoltaic inverters for grid-connected power generation must have low voltage ride-through capabilities to ensure the normal and stable operation of the power grid. In recent years, bidding for photovoltaic inverter projects at home and abroad has taken low voltage ride-through capabilities as a threshold for entering the photovoltaic field. The successful passing of this test is another strong pass for CSR photovoltaic inverters to enter the photovoltaic market after obtaining the "Golden Sun" and "TUV" certifications.

The exploration and development of the photovoltaic industry is an important banner for CSR to respond to the country's "low-carbon and environmentally friendly" sustainable development policy, adhere to the company's "concentric technology diversification" development strategy, rely on core technology advantages such as power conversion in the rail transit field to explore the new energy market, and create a new image of an international professional supplier of electric drive and control systems in the new energy field.

CSR's photovoltaic industry insists on the path of "independent research and development, high-end substitution". After cultivation and incubation in recent years, it has now formed a complete product series of 50kW-1000kW photovoltaic grid-connected inverters, photovoltaic lightning protection combiner boxes, combiner boxes and sun tracking systems. It has completed and put into production three "Golden Sun" national photovoltaic power generation application demonstration projects, and took the lead in realizing the high-altitude application of photovoltaic inverters. It has established long-term strategic cooperation with well-known domestic new energy companies such as Huangming Group, China Electronics Technology Group Corporation, Zhuhai Xingye, Qinghai Development Investment, and Qinghai Encyclopedia.

As one of the first six manufacturers to pass the experiment, CSR not only broke the conventional practice of one week for this experiment, but also completed three times the test items of other manufacturers in four days. It also simulated the on-site mobile detection equipment test, and the waveform and data showed good. This once again fully demonstrated the deep technical strength of CSR as a high-quality and professional photovoltaic inverter manufacturer, which is of far-reaching significance for the company to accelerate the development of the photovoltaic market and create the first high-end brand of domestic inverters.
