In Europe and other countries photovoltaic applications earlier, "distributed" grid PV market has become mainstream, and look back at our country in recent years, more emphasis on large-scale popularization and application of large-scale power plants, related to statistics more than 70% of the photovoltaic installed capacity comes from large-scale photovoltaic power plants, "distributed" equipment accounted for only two percent. Relative to the large-scale photovoltaic power plants, distributed photovoltaic equipment mainly installed in homes, factories roofs fine, because the grid, tariffs, subsidies, and many other uncertain factors, therefore the popularity and development of distributed, will was recently a long way to go in the process.
Not long ago the relevant state departments in 2012 officially released "on the good services of distributed photovoltaic power generation and network views of the work" and other relevant policy documents, efforts to promote the domestic development of distributed photovoltaic power generation, to encourage units, communities and families Installation , the use of photovoltaic systems. Domestic "distributed" smooth opening of the market will undoubtedly become the PV production capacity to digest a new outlet.
Distributed photovoltaic power generationmicro-inverter to become the focus of much attention, the DC power conversion from a single solar module exchanges, each solar cell module is equipped with an inverter and converter function, each component can be individually currents conversion, and can level the panel maximum power point tracking (MPPT), beyond the central inverter has advantages, to optimize the output power of the module, the overall maximum output power.
Micro-inverters generally use reverse isolation topology, not inject DC bias current to the grid, DC side and AC side of the isolation, machine damage, solar panels will not affect the power grid; Second, each photovoltaic panels with a micro-inverter , no DC high voltage, there will be no risk of electric shock, no arc; each individual photovoltaic panels generate electricity, anti-shadow characteristics, the inverse of a micro-inverter is damaged, does not affect the power generation system; ease of installation, which for the United States and Europe expensive PV installation cost is a huge advantage.
It is reported that since 2009 off grid inverter assive sales in the U.S. market has been gradually occupy the country with 30% of rooftop PV market share, this share continues to increase. And because micro-inverters are easy to install and use transformer isolation, Western countries have very broad market prospects.
Faced with such a broad market demand, Samil Power Co., Ltd. (hereinafter referred to as "Samil Power") actively increase slightly inverse product development process, launched in 2012, respectively, for North America and Australia, Europe, China market The micro-inverter Solar Pond 240HF-US and Solar Pond 240HF-AU.
With foreign brands compared to mainstream micro-inverter, Solar Pond 240HF-US volume, efficiency considerably, maximum continuous AC output 240W, 11% higher than the foreign mainstream products output power, which is able to meet all household rooftop photovoltaic panels and large some commercial photovoltaic panels;
At the same time, Solar Pond 240HF-US and Solar Pond 240HF-AU warranty life of up to 25 years, while the general peer micro inverse lifetime warranty is only 10 years, thereby greatly reducing the user's entire life cycle cost, and saves installation costs; in domestic counterparts, efficiency, and the whole volume is much better than its competitors, and the Solar Pond 240HF-US through a CSA certified, and its authority is much higher than domestic competitors ETL certification.
To further validate Samil Power developed by the micro-inverter power under different weather conditions in the reliability and stability, and ability to adapt to the actual grid, Samil Power in December 2012 R & D center in Shenzhen Rooftop installed micro inverse and power generation systems.
The system covers the four kinds of domestic and commercial specifications of solar panels, a total of 16 panels, the total system power 4000W, equivalent to the capacity of an ordinary family, each equipped with a miniature solar panel inverter Solar Pond 240HF-AU, monitoring system is used Samil Power homegrown Solar watcher 100.
Solar Pond 240HF-AU and Solar watcher 100 through wireless communication between a station Solar watcher 100 monitors 100 Solar Pond 240HF-AU, fully meet the domestic and small commercial rooftop systems. Micro-inverters and power generation systems Another important objective is to verify the reliability of communication to ensure that users can get real-time power data to calculate revenue generation and monitoring occurs during the operation of the various events and information, to provide reliable The solutions and network communication.
Micro-grid system is inverse Samil Power R & D Center R & D personnel, installation and commissioning, the entire system to run successfully, marking Samil in product development and an important step forward, creating a product development inverter another milestone. Future Samil Power will implement national policies related to distributed generation, and always do the most reliable and stable inverter products first, and actively cooperate with relevant departments to promote distributed generation healthy, orderly and science to before development
