China inverter how to "go out"

In recent years , the photovoltaic industry has become the new energy industry has attracted the attention of a bright star in the horizontal and vertical development have brought about a large number of enterprise development, elaborate domestic photovoltaic enterprises, it is the only one with its own advantages for development , in the more short period of time , and lead the world to become peer beyond the strategic , sustainable new industries.

However, the field of photovoltaic technology and applications in the world is just the middle or lower level . The main reason is the domestic solar photovoltaic cells have not yet mastered the required silicon purification technology . The technology is currently being monopolized by big foreign companies , domestic production of solar photovoltaic cells and therefore high cost . The cost of photovoltaic power generation cost is usually several times , and therefore can not cause widespread popularity .

Upstream relative to the core in terms of PV dc to ac power inverter technology , they can already compete with international brands on the same stage , many enterprises have gradually inverter is emerging on the international stage , to participate in international competition among . Domestic enterprises in the industry-leading inverter no less than a few , such as the main job of the power of the sun within the domestic market , both inside and outside " alike " in Samil Power Co., Ltd. , etc. These companies regardless of the company's overall strength or R & D strength and product quality. forefront of the industry .

Nowadays domestic enterprises to go out inverter nor difficult, but China inverter for many reasons not able to occupy the U.S. or European markets , but also be able to gain a place of rare . Since the entire solar system inverter only 7% of the total cost . A relatively inexpensive inverter price impact on the system is not so big, so buy a cheap but lesser-known Chinese brand inverters advantage is not obvious.

Careful analysis of reasons , first choice of material , the inverter is different from the assembly of electronic products belong , in order to achieve the desired quality and conversion rates , the internal components selection also appears to be crucial , but also to ensure the stability of the product , so with excellent suppliers to establish long-term stable cooperative also can not be ignored . Many enterprises are micro grid tie inverter sold at low prices , mainly because most of the internal components are not on the selection of internationally renowned supplier of products in the eyes of foreign customers will certainly be greatly reduced.

Secondly, technology, technology has always been the core of electronic products , the inverter is stable or not , and is closely related to the level of conversion efficiency , and a strong R & D team or the level of product technology and also blood interlinked , like the international brands of digital , appliance industry , they are undoubtedly the industry's top R & D team , and ensure that the product innovation.

Local customers rely on local products thinking largely crowded out foreign enterprises , local enterprises may in product performance and price are slightly inferior to foreign products , one chip, but after all, has prejudiced the minds of customers has been formed at a local brand . China 's enterprises in order to further the inverter must first make the product popular market , breaking customer conventional thinking .

In services, companies can set up local offices or branches , and with local service team to serve local customers , giving enterprise local flavor . In terms of products , to ensure product quality and establish a corporate trust in the minds of local customers . In market development , through the use of strategic cooperation model with local upstream and downstream enterprises to establish good cooperative relations.

Correlation analysis institutional analysis, Samil Power Co. them in Europe, Australia market development achieved good results, PV inverter shipments exceeded expectations , with great potential is the one of the inverter , it is learned Samil new energy to meet and adapt to the needs of the local market development , worked in Europe, Munich, Germany , set up branch offices in Sydney, Australia , the local establishment of professional technical service team.

German exhibition I had the honor to interview Samil Power relevant person in charge , informed Samil market development in Europe has been quite effective, products successfully applied in Germany , Italy, Britain , France and other dozens of countries and regions , products and services have been recognized by customers , Samil Power brand also withstand the test of the market and customers , has become a benchmark for standing firm in the European market .


I believe that with the domestic enterprise technology after a certain time of the precipitation and accumulation, there will be more competitive on the international enterprise inverter stage , so that Chinese -made inverter installed around the world , for the world cleaner green energy.

Solar photovoltaic inverter grid layout and safety issues

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 modified sine wave 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.
