East China Power developed the production of "500KW PV Grid Inverter" passed up the only low voltage ride through technology certification bodies "State Grid Electric Power Research Institute, the National Energy solar power research and development (experimental) centers" in low-voltage ride through (LVRT) test.

According to the National Energy Board, the State Grid Corporation of photovoltaic power plants and power generation requirements and grid PV inverter must have low voltage ride through capabilities to ensure normal and stable operation of the grid, has LVRT capability for entering the PV field of a threshold.

Based on this, as a rising star of the domestic photovoltaic power generation, Weihai Huadong Power Co. 500KW inverter independently developed a collection company more technical experts to form the low voltage ride through experimental research team initiated research the technical problems, and finally passed with the only low voltage ride through technical testing qualification Nanjing State Grid EPRI test trial, which was obtained by following the Eastern power "Golden Sun", "TUV" certification is another important "weights", fully embodies the East China power as a quality , a professional manufacturer of photovoltaic inverters strong technical strength, expanding its PV inverter market, domestic inverter creates a favorable impact on high-end brands.

East China Power photovoltaic industry stick to the "independent research and development, high-end alternative" road, after recent years to cultivate and incubation, has formed 10KW-500KW PV Grid Inverter, off grid modified sine wave inverter, combiner box, AC and DC power distribution cabinets, etc. complete product series, and other countries have been completed Wen Deng Nanhai Golden Sun Project photovoltaic demonstration project.

LVRT test is passed, marking the East China Power PV market more competitive, improve product quality and technical level to a new level, fully equipped to undertake different types of photovoltaic project conditions, and has entered the National Energy Board, State Grid Corporation of photovoltaic power plants and power generation threshold.
