What is a photovoltaic inverter? With the rapid development of society, our photovoltaic inverters are also developing rapidly, so do you know the detailed information analysis of photovoltaic inverters? Next, let xiaobian lead you to understand the relevant knowledge in detail.
Europe/Middle East/Africa (EMEA) has historically been the region with the greatest demand for pv inverter replacements, as the core markets of Germany, Italy, Spain, the Czech Republic and Bulgaria experienced an early boom in the solar market, with the highest percentage of PV system installations over five years.
With the approach of affordable Internet access, cost reduction, efficiency improvement and intelligent upgrading have become the urgent demand of the photovoltaic industry. As the key equipment of photovoltaic power generation, the inverter has been updated and iterated under the stimulus of favorable policies, and has become the "engine" to promote the era of parity. In 2019 alone, more than 11 million PV inverters will ship around the world, most of which will be connected to software platforms and controlled by inverter companies, according to IHS's latest forecast. At the same time, the new development situation also put forward higher requirements for inverter power level, voltage level, capacity ratio, overload capacity and so on, so that the development of inverter technology and market into a new stage.
Asia ranks second because of the huge replacement demand in China. China has many older large pv installations and has recently seen massive growth, which will continue to drive demand in this region. The replacement demand for pv inverters is expected to come primarily from utility-scale (5 MW) facilities. Residential and commercial facilities will also drive demand in Japan due to early solar growth. Japan currently ranks first in the world in the number of residential facilities built over five years ago.
In China, photovoltaic inverters have been researched and developed since the 1980s, and now there are specialized companies researching and developing grid-connected inverters. Start time later because the terminal market, the domestic photovoltaic inverter manufacturers generally on a smaller scale, structure, process, work, performance stability index with the first-class enterprise has certain gap, but to occupy the domestic market more than 60% of the leading enterprises in hefei sunshine power company has achieved rapid development, and has to enter the European market and other high power markets abroad. At present, hefei Sunshine company's main competitors for Germany SMA, Satcom and other international manufacturers, but the high cost, long delivery cycle is the main obstacle for foreign manufacturers to enter the domestic market, investment in domestic production and sales is the necessary way for foreign manufacturers to seize the Chinese market
In the process of digitalization and intellectualization, more and more energy management functions will be added to photovoltaic inverters. First, photovoltaic energy storage management function. The importance of energy storage for large-scale grid connection of photovoltaic and other new energy is self-evident. The application of optical storage system, further drive inverter to power station energy management center evolution. Second, safety management function. The inverter equipped with such skills as DC arc pull-out detection, module quick turn-off and protection changes the safety protection of photovoltaic power station from passive to active. Third, automatic monitoring and early warning operation and maintenance management functions. Fourth, household micro network management functions.
At present, the domestic production of inverter manufacturers, professional research and development of photovoltaic power generation system inverter manufacturers are not many. Manufacturers with large horizontal production capacity mainly include Hefei Sungrow Power Supply Co., Ltd., Nanjing Guanya Power Equipment Co., Ltd., Beijing Kono Technology Co., Ltd., and other enterprises, the photovoltaic inverter technology and output of these enterprises has shown a rising trend year by year, some enterprises have successfully developed large inverters. Due to the low production cost, mature technology and stable product performance of photovoltaic inverter suppliers, so the gross profit margin of the inverter can be maintained at 35%~40%.
