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
