Recently, the reporter learned from the Ming Yang Technology, Guangdong Mingyang Electric Group Co., Ltd. developed the production of high-power 1MW photovoltaic grid inverters (Model MYsolar-1000TL) successfully passed the National Energy solar power research and development center low voltage ride through certification testing. This marks the company Ming Yang inverter technology has made a major breakthrough.

Ming Yang is a single stage inverter MW by State Grid EPRI LVRT certification testing second domestic companies, is using two MW-level photovoltaic inverter topology and successfully passed certification tests LVRT first enterprise. According to the company officials briefed reporters on the next step, the company's R & D center will trade higher difficulty PV zero voltage crossing test challenges!

It is reported that, 1MW inverter circuit topology with conventional topologies in different ways, technology is more difficult, more demanding. Therefore, the test demonstrated through full Mingyang in inverter technology R & D strength FredeBlaabjerg too few professors this review article inverter has reached nearly 1,000 reference number, which in the field of power electronics has been very amazing.

And when he was the IEEE Power Electronics Technology (TransactiononPowerElectronics) editor in the past few years, the PV inverter has become a very hot research field. Personally, I think the article is very accurate prediction, since 2008 Enphase company introduced the first commercial product, the micro-inverter http://www.gridtiepowerinverteronline.com/ begins to be academic outsiders who know the company by virtue of its advantages in Silicon Valley development is very rapid expansion financing fast, then quickly followed several other brands compete.

First, wait several major brands, recently began the layout of the micro-counter market. Industry leader SMA bought the micro inverse Pioneer OKE-Services product platform OK4ALL, and thus developed a micro inverse products SunnyBoy240. This product is currently only available in the United States of SMA website you can see, the specific time is unknown. PowerOne also in 2011 launched its own micro-counter product AuroraMicro.
