November 5 , easy special self-developed 500KW PV inverter successfully passed the State Grid Electric Power Research Institute experimental validation center of the world's most stringent zero voltage crossing tests. The testing and certification that easy special power 500KW PV inverter is fully in line with national grid " photovoltaic power plants connected to the grid test procedures" and the latest national standard " photovoltaic power plants connected to the grid technology provides that" zero voltage across the photovoltaic plant functional requirements . Marking the company's PV inverter technology standards to achieve world-class level , the future PV market for the company 's rapid development has laid a solid foundation.

   The test carried out strictly according to the latest national standards , not only requires PV inverters with zero voltage crossing function, but also require it to have a grid voltage drop during dynamic reactive power support capabilities. It is also easy special 500KW PV inverter Following the success of last year through the low voltage through the test , the company continued research team to overcome technical difficulties , and in the short time successfully completed the world's most stringent zero voltage across the test , a breakthrough photovoltaic field Also a technical threshold .

    According to reports, the zero voltage crossing is the core technology of photovoltaic equipment , and network security is to determine whether the key indicator , is due to grid PV power plants in order to prevent malfunction causes a voltage drop caused by the collapse of the entire power grid , causing widespread power outages and set new national standards . And low voltage ride through (LVRT) technology, more demanding, more stringent testing .

A short circuit due to a fault in the power grid , the voltage drops , the PV grid-connected inverter must remain off-grid , and follow the instructions to the grid dispatching certain reactive power injected to help restore power to provide dynamic voltage support, protection grid stability normal operation. The introduction of standards for many photovoltaic inverter manufacturer is a severe test of the technology , currently only a few companies easy Principal passed this test certification.

    Successfully passed the test and is easy special over the years in the field of new energy applications continue to promote technological innovation, continuous improvement photovoltaic inverter performance and reliability of the indicators achieved a major breakthrough , marking its photovoltaic inverter technical indicators have reached the international first-class level , solar photovoltaic systems for the company 's research and development of products set a new milestone.

Currently, the easy special photovoltaic grid-connected inverter has worked in Xinjiang, Gansu , Jiangsu, Qinghai, Ningxia , Guangdong and Germany, France, India and other domestic and foreign large-scale solar photovoltaic power plant construction , Golden Sun PV demonstration project has been widely applications, and achieved good social and economic benefits.
