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 inverters 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 with charger '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 .

 Denmark's largest industrial group Danfoss COO Fang Xingjian recently in an interview with this reporter , said his company would consider entering the Chinese solar inverter market.

    Fang Xingjian said that as the international PV market downturn last year , its business in Germany inverter appeared about 30% of the decline, but overall, its inverter business in the world also tend to rise .

    "This is mainly caused by the decline in some applications , but we believe that this business will soon be able to recover just a typical case of Germany, and not as a key factor in overall consideration ." Fang Xingjian said .

    As for the Chinese market , Fang Xingjian said, " If we consider the Chinese market, we now share may be close to zero , but Danfoss has been in focus , as well as doing some preparation to how to better enter this market, occupy a certain market share . "

    But he also said, " China market access in other countries may be slightly different market entry , China may be mainly concentrated in several large power plant facilities, and demand for products is diverse, so we are considering this issue , there may be some difficulty entering . "

 Recently, the SGS International Certification Services Division technical expert review, Jiangsu solid Dulwich fully passed ISO9001: 2008 quality system certification , the certification include: solar photovoltaic inverter design , development, production and services.

SGS technical experts audit finds solid Dulwich in Jiangsu PV inverter product design , development, production process in strict accordance with the ISO9001 standard can but executed layers of managers focus on leadership and full participation in the quality improvement philosophy ; customer focus to enhance the quality of service ; will manage the process approach into practice .

    Jiangsu solid Dulwich since its inception , the principle of " first-class quality , hard service" for business purposes, to provide customers with high-quality, high-efficiency photovoltaic inverter responsibility, and strive through 5-7 years of rapid development , the world's leading clean Energy inverter supplier. Obtained ISO9001 quality system certification , in order to achieve this goal, laid a solid foundation.

    It is learned that Jiangsu solid Dulwich was founded in 2010 , mainly engaged in solar , wind inverter R & D , production and sales . The first phase of one-time investment 120 million yuan . Research and production of photovoltaic power inverter http://www.gridtiepowerinverteronline.com/ products covered 1.5KW to 500KW, a full range of photovoltaic inverter maximum conversion efficiency of 98.8%, MPPT tracking efficiency of over 99.5 %, total harmonic distortion (THDi) control in 1 % or less, product performance has reached world- class level. 100KW-500KW PV inverter unique centralized low voltage ride through , STATCOM , intelligent anti- backflow protection techniques , such as three , is the construction of photovoltaic power plants inverter products the ideal choice.

 December 2011 7-9 , Intersolar exhibition for the first time into the China International Photovoltaic , holding a variety of expectations, businesses and practitioners came to the National Convention Center , Hall is not great, but the atmosphere is hot, in the winter to PV market has injected a shot in the arm - If winter comes , can spring be far behind ? the exhibition , which attracted some well-known domestic photovoltaic inverter companies, including companies from Germany Redford unveiled new 20 kilowatts and 333 kilowatts high performance PV inverter , as well as innovative photovoltaic system monitoring solution . Reporters on the 8th and Redford 's general manager of Miss Yao Shang China on the development trend of the inverter are discussed .

YAO Shang Jieshao , Redford company in this exhibition -phase photovoltaic string inverters REFUsol020K. This compact PV inverter rated AC power of 19.2 kilowatts , can be smoothly integrated in the solar photovoltaic power generation device in order to achieve maximum output. It weighs only 41,5 kg , easy to install , and saves space. Even at low levels of solar radiation , excellent MPP tracking system and a broad range of input voltage 480 to 850V The PV inverter can also reach a peak efficiency of 98.2% . The highly efficient , based on the successful use of Redford convection cooling technology to achieve cooling . As the ground voltage fluctuation is very small , this photovoltaic inverter can be used for various thin film solar panels .
