Growatt’s two power station photovoltaic inverters completed zero voltage ride-through testing at one time

International New Energy Network News: Zero voltage ride-through is a rigid safety regulation requirement proposed by the State Grid to protect the safety of the power grid. The new national standard requires that the inverters for grid-connected power generation in photovoltaic power station systems must have low voltage ride-through (LVRT) and zero voltage ride-through functions. Compared with low voltage ride-through (LVRT) technology, zero voltage ride-through has higher technical requirements and more stringent testing.

The test was conducted in strict accordance with the State Grid's "Test Procedures for Photovoltaic Power Station Access to the Grid" and the latest national standard GB/T19964-2012 "Technical Regulations for Photovoltaic Power Station Access to the Grid". During the test, the Growatt CP500TL/630TL models met the standard requirements in terms of various technical indicators such as waveform and data, and all passed the zero voltage ride-through test in the shortest time at one time.

It is worth mentioning that after passing the test, Growatt became the second inverter brand in China to pass the zero voltage ride-through certification for both 500KW and 630KW models, and all kinds of technical indicators have reached the leading level in China.

As one of the leading inverter brands in China, Growatt has developed 500KW and 630KW power station inverters based on its strong R&D strength in photovoltaic grid-connected solutions and rich global grid-connected installation experience. The inverters have the characteristics of high efficiency, high power density, easy operation, safety and reliability, and are currently one of the models with the highest one-time grid-connected success rate in domestic installation sites. So far, this model has been installed in many power stations in Qinghai, Xinjiang, Inner Mongolia, Zhejiang, Shandong and other provinces, and has won unanimous praise from customers.
