Growatt inverter into the "Millennium institution" Lake stable operation of large photovoltaic demonstration project

From the " Millennium institution " Hunan University news came new energy provided by the Guruiwate Growatt inverter PV project in Hunan University to maintain efficient operation , stable performance ! Lake 30kw solar power demonstration project is the project has been successfully running eight months , according to plan generation is not less than 45,000 degrees each year , which can basically achieve self-sufficiency in electricity floors surrounding the project . Lake demonstration project to achieve a thousand years of cultural heritage and the perfect fusion of modern green technology for Hunan university teachers and students teaching practice provides a great convenience .

   CLC project , the project uses thin-film modules , as opposed to conventional components , one can effectively control the cost of the entire project , but the performance of the inverter will put forward higher requirements , especially in the voltage range and how to ensure that the film component life put forward a great challenge. The open circuit voltage of the film components is generally about 80 volts beyond the conventional components of the open-circuit voltage of 30 volts , so the operating voltage range of the inverter demanding .

And this project Guruiwate provided Growatt5000MTL new energy models operating voltage range of 120-550 volts, the voltage range is high and wide to effectively adapt to the needs of the project . In addition , the thin film battery itself is corrosive , in particular its negative bias voltage , the stronger the higher the resistance , the greater the impact on their life . To this end , Growatt pure sine wave inverter specially developed proprietary grounding module , allowing thin film battery negative ground , in order to eliminate the negative impact of bias effective in ensuring its life.

   To control the leakage current on the inverter 's own life of thin-film modules , Growatt with dual asymmetric boost circuit with three-level topology , with a unique control algorithms implemented using dual interleaved boost circuit , which greatly reduced the DC side voltage ripple , tested in the worst case ( humidity exceeds 95% ) leakage current less than 2mA, will affect the life of thin-film modules are minimized.

   As China Inverter http://www.gridtiepowerinverteronline.com/ leader in overseas markets , Guruiwate new energy involved in numerous projects abroad , has accumulated a wealth of experience. In this square in cooperation with the project is also actively involved made ​​many useful suggestions . According to the project CLC, Guruiwate new energy in the entire course of the project whether products or employees have shown a very high professional level , but also expressed Guruiwate new energy thanks to the entire project team .
