In developed countries, low tariffs , electricity widely available . But in Africa, weak infrastructure, electricity , electricity is very common. People use car batteries to charge your phone . Kerosene is commonly used lighting equipment, but also very dirty and dangerous .

        As countries far behind the growth rate of power demand growth , more and more Africans are no longer seeking centralized fossil fuel -based solutions, but turned to solar energy.

        So far , solar dc to ac inverter in the African energy mix is only a secondary role, but the growth of solar energy utilization in Africa marked the turning to renewable resources . In 2004, Africa 's renewable energy industry scale is only $ 750 million . In 2011, this figure had reached $ 3.6 billion . Late last year , the United Nations predicts that by 2020, Africa 's renewable energy sector will reach $ 57 billion .

        Particularly suitable for solar central Africa and eastern equatorial regions ample illumination , an entrepreneur , said: " Here, energy shining on our heads every day ." In recent years , the region has become a haven for renewable energy , some of the leading technology small companies eager thirst for energy from the Southern Hemisphere digging opportunities.

        Headquartered in Silicon Valley, USA FenixInternational is such a company . The company has developed a plug and play battery ReadySet, through solar panels or bicycle charging. Although ReadySet has a range of features ( it has a USB port and car cigarette lighter port ) , but it is primarily designed to help users in the absence of local power grid to charge your phone .

        According to industry association GSMA gridtiepowerinverteronline mobile operator 's data , the first quarter of this year , sub-Saharan Africa 's mobile phone network to more than 500 million total . This figure is expected to increase over the next five years will be 250 million . In Africa , many people have cell phones , but not necessarily supply. They are part of the global shortage of mobile phone users , these users in 2009 is expected to be 500 million people . No electricity supply, means that many dead battery .

        " Africa 's mobile phone network grew very alarming ," Fenix ​​CEO and founder Lin Maike ( transliteration ) said, " This is our opportunity to fancy ."

        So far , Fenix ​​has sold 3,000 units in Uganda ReadySet ( Uganda Fenix ​​sales office is one of the largest ) , 5,000 units were sold worldwide . Early users include some of the entrepreneurs, they use ReadySet charge for local phone charging service users .

        "It's like a mini- license ," Fenix ​​East Africa Regional Director Lindsay • Handler said, " It is a simple and can scale solutions using this box , one year can get a steady income ."

        Initially credit card loans to $ 100,000 from scratch founded this company Lin Maike recently completed a new round of financing , attracted to the France Telecom Orange and energy management company Schneider Electric (SchneiderElectric) such a large corporate investors . Lin Maike expected , Fenix ​​will be in the next two to three years to achieve profitability.

 Recently, Jiang Su Lvyang New Energy Technology Co., Ltd. self-developed 500KW and 250KW PV Grid Inverter passed the National Golden Sun certification. This is the second 10KW and 100KW PV inverter , the company made ​​the two products have the certification .

Jiang Su Lvyang New Energy Technology Co., Ltd. as an emerging PV micro grid tie invertermanufacturer , since its inception has been committed to the development of independent intellectual property products , one after another to obtain a large number of results , some products have passed TUV, CE, QC080000, AS4777 and many other certification and testing .

Companies with domestic and international well-known institutions to maintain long-term , good R & D partnership to set up a " solar, wind grid inverter Systems Research Center ," and the identification of national science and technology sector , while the company and the Ministry of Education, photovoltaic systems engineering research establishment of a comprehensive research cooperation between the center and made the core technology in the field of solar inverter breakthrough .

As the " Golden Sun" certification is a PV inverter into the nation-building "Golden Sun Demonstration Project " a necessary condition to obtain certified Green Solar Energy is a recognition of the quality products , the company is bound to the development of photovoltaic industry into a strong driving force. Green Solar Energy will continue to insist on doing the most reliable inverter, is committed to the development of new energy sources .

 Governments and power companies are expected , photovoltaic (PV) power generation will supply the amount of energy they account for a large proportion. The solar cell is converted into direct current and alternating current power grid synchronization , the design can be demanding in the future even more so. PV inverters have a wide power range and operating conditions to achieve maximum efficiency , and must also comply with strict safety requirements. Ultimately depends on performance of the inverter based power accurately measured . PV inverter manufacturers need to work closely with the sensor manufacturer , to ensure support for the latest trends in photovoltaic technology .

Our world is asked to use "green" renewable energy alternatives to fossil fuels to benefit the environment . Forecast for the near future reality of the power supply system includes a variety of energy scenarios , in which there are a variety of configurations scale solar energy , both covering several hectares of large-scale power plants , there are also single-family use of the device. This will promote the photovoltaic (PV) solar inverter market, strong growth. Even in the current economic downturn , it is expected PV market in 2013 will reach 34 billion U.S. dollars . About PV market considerations , a relatively new device is expected of all sizes will be connected to the grid ; Even the single-family home system, if the load generating capacity exceeds local needs , but also to the power transmission and sale of electricity companies .

PV system to achieve its potential, it is necessary to improve the efficiency of power generation in order to reduce the cost per kilowatt . As we all know , solar cell manufacturers have been working to enhance the solar radiation into electricity based efficiency ; manufacturers are designing the next generation of photovoltaic inverters, diagnostics and other features by adding increasing power and efficiency , increased intelligence and functionality. The latest trend is a multi- string technology : the series connected solar cell consisting of a plurality of series connected to a single grid tie power inverter, wherein each cell has its own maximum power point tracking (MPPT) device , thereby maximizing energy production . Solar power cells are difficult to use .

Battery is open, the output voltage of about 0.6 volts nominal : Normally each solar panel up to 72 cells , the formation of 44 volts open circuit. The battery can be a certain level of short-circuit current of the output . At a point between these limits , the battery voltage and current in a lower maximum power output . This maximum power point with the operating conditions ( such as the projection of solar radiation ) changes, so this point, the inverter must be tracked in order to maintain maximum efficiency. Designers rely on the instantaneous voltage and current data acquisition sensor, software algorithms do this.
