In the photovoltaic industry chain, the inverter has always been considered one of the links is the most technical threshold. Or why, in 2010, the photovoltaic industry crazy expansion, the expansion of the inverter industry was slightly some of the "rational", and in the subsequent industry-wide rapid price, the price cut and the speed was much more moderate.
However, since the second half of 2012, the market price of the inverter wave of rapid fill-off, high-power cut by about 8 cents per watt to about 4 cents. For a single watt inverter price is not that high, so fast and up to 50% price cut, no doubt their ability to control costs severe challenges.
Known as the inverter is able to produce as well as sporadic shipping companies in the market, also have sprung up hundreds. The competitive situation of the domestic inverter market, a time of intense unprecedented. As Shaanxi Changling Photovoltaic wind inverter Electric Co., Ltd. (hereinafter referred to as "Changling PV) current chief engineer and chief technology officer, graduated from Xi'an University of automatic control professional OF RADIO, almost in Changling Group engaged in the power of the" lifetime " electronic product development and technology management. 2010, Changling PV inception, OF RADIO has served as the main technical person in charge, and accompanied by Changling PV development and growth so far.
In early April 2013, "mppt solar charge controller power" magazine reporter went to the Changling PV headquarters is located in Baoji City, Shaanxi Province, an exclusive interview OF RADIO PV inverter technology development and the current competitive situation and other related issues. "Inverter there is indeed a technical threshold" Some people think that the inverter is the photovoltaic industry chain, not more than a technical threshold link, how do you think this is? OF RADIO: the development and manufacture of photovoltaic inverters, a variety of techniques involving power electronics, power conversion technology, maximum power point tracking technology, phase-locked loop technology integration, safety, EMC, power quality and conversion efficiency have a more high demand.
Same time, the photovoltaic system to run two or three decades particularity in the open-air environment, but also put forward higher requirements on the use of reliability and life of the inverter, its life must be more than two decades. Due to the integration of various technologies, and the use of environmental constraints, different from the PV inverter power electronic products have special requirements, its design, production and quality control. Therefore, relatively speaking, the inverter indeed be regarded as more of a part of the technical threshold in the photovoltaic industry chain.
