recently developed by the China Shipbuilding Industry Corporation seventh thirteen studies assume 500KW PV inverter , Electric Power Research Institute of China National Energy solar power research and development ( experimental ) passed the low voltage across the test , and obtain the corresponding test report. Testing and certification , this type of inverter in full compliance with the the national grid photovoltaic power plants connected to the grid technical requirements " Grid tie inverter, " photovoltaic power plants connected to the grid test procedures across the functional requirements of the low voltage of the photovoltaic power plant .
low voltage across the grid voltage drop occurs in the case of the photovoltaic inverter can be kept in certain conditions and the time range and network, to support the grid fault recovery power inverter, thereby "through" the time of this low - voltage , to avoid causing the grid the failure of the enlargement . Low voltage ride through technology to improve the security and stability of the grid system . http://www.gridtieinverter.de/
