2018 market share of different kinds of inverter and efficiency

Solar photovoltaic webex photovoltaic inverter is one of the main components of photovoltaic power generation system, pv inverter main function is to send the dc component is converted into alternating current (ac), and follow up the maximum output power of pv array, its energy to the smallest conversion loss and best quality feed into the electricity grid.

photovoltaic inverter in accordance with the applicable places can be divided into centralized inverter, collecting and distributing type inverter, set of string type inverter and micro inverter. In 2018, pv inverter market mainly centralized inverter and still set of string type inverter is given priority to, miniature and distribution type inverter is small. With the rapid increase of distributed photovoltaic market and centralized in the photovoltaic power station group increased proportion of string type inverter, set of string type inverter market proportion reached 60 in 2018. 4%. Centralized-distributed photovoltaic inverter than centralized inverter ascension MPPT control effect, and compared with the set of string type inverter solution has low construction cost. Market share, therefore, present a rising trend year by year. 2018 - 2025 market share of different kinds of inverter as shown in the figure below.

in 2018, the centralized inverter efficiency of China in 98 on average. About 3%, and distributing type inverter in 98. About 4%, group of string type inverter in 98. About 4%. The inside of the inverter power semiconductor devices and magnetic devices in the process of work produced by the loss is the main factor that influence the efficiency of the inverter. As the future silicon semiconductor power device to further improve the technical indicators, silicon carbide and other new type of efficient semiconductor material technology matures, gradually reduce the unit loss of a magnetic material and combined with better topology and control technology, power electronic transformation inverter efficiency there is room for further increase in the future. The figure below 2018 - is presented 2025 different types of inverter efficiency of China's change trend.
