Nanjing Guanya 500kW PV inverter successfully passed the China Electric Power Research Institute to test the zero voltage ride through

Division I independent research and development of 500KW PV grid-connected inverter successfully passed the national power research solar energy China Electric Power Research Institute (test) center zero voltage ride through strict test. The testing and certification indicates that Nanjing Guanya 500KW PV inverter power is fully in line with the national grid "photovoltaic power plants connected to the grid test procedures" and the latest national standards, "the provisions of photovoltaic power plants connected to the grid technology" for zero voltage across the PV power plant functional requirements . Marking the company's PV inverter technology level has reached world-class level, and laid a solid foundation for the rapid development of the future PV market companies.

Zero voltage crossing is rigid safety requirements for the protection of the national grid and grid security proposed. The new national standard PV power plant system grid inverter must have low voltage ride through (LVRT), zero voltage ride through capabilities. Zero voltage across the low voltage ride through (LVRT) technology compared to the technical requirements are higher, more stringent test.
