PV Inverter companies gathered seize the Chinese market

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 grid tie power 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 .

In addition , Redford also exhibited REFUsol333K photovoltaic inverters . According to reports, this product has a degree of protection IP65 , suitable for outdoor installation , can reduce the overall cost of photovoltaic power generation system . Has a power rating of 333kW and a unique patented UltraEta?? Circuit topology , the PV inverter which can reach peak efficiency of 98.5% , and optimize the energy conversion and use. REFUsol333K to 690 volts AC voltage, which is the industry standard network and the voltage level of wind power plants . Its maximum DC voltage up to 1500 volts. Therefore, the industrial production standard transformers and compensators with which supporting the use of photovoltaic inverters .

In order to facilitate remote monitoring operator efficiency photovoltaic systems , Redford provides specialized Internet portal REFUlog. Integrated data collection devices , regardless of day and night can monitor photovoltaic systems. PV dc to ac inverter can configure an interface to connect to the local network and the Internet. For example, installing 20 kilowatts or Plug and Play devices can be installed via an Ethernet connection . Thus can learn anytime, anywhere PV inverter operation.

Managing MichaelSeehuber Redford expand sales , said: " China 's PV market growing rapidly, and has become a vital member of the global market , we have long recognized the tremendous potential here , China in our global strategic position in the important. Shanghai and the future establishment of the company have witnessed the localization of production for the Chinese market continued investment in our long-term commitment to development . "
