According to market research firm IMS Research IHSiSuppli its latest report revealed that with the PV inverter supply market in 2012 to further differentiate this year, a quarter of the global top ten inverter supplier market share fell more than 4% of the total .

IMS Research believes that part of the reason is that China and Japan, strong growth in market demand , and the world's top ten suppliers of inverter most companies business in both markets is relatively limited . With the PV market differentiation and core markets continued weakness in demand for products , SMA company in the global market accounted for the third consecutive year revenue decline, its market share is now only slightly higher than 25%. The recent burst of mergers and acquisitions wave , including AdvancedEnergy acquisition REFUsol, ABB Group acquired Power-One , including almost no impact on the competitive landscape , and the impact of supplier ranking is minimal .

PV inverter supply market differentiation although in general , there is more from the bankruptcy exit and merger cases implies industry is undergoing consolidation, but the world's ten largest PV inverter supplier 's market share only from 62% in 2011 fell to 56% in 2012 , the change is small.

2009 with nearly 40 % market share compared to 2012 SMA inverters DC TO AC in photovoltaic market leadership further decline in market share only slightly higher than 25%. IHS PV inverters research manager Sam Wilkinson said: " During the year 2012 , because business is still concentrated in the tradition of weak growth in the European market , and in the rapid growth of China and Japan, lack of market development , including SMA, Power-One and Kaco three regicide transformer suppliers , including many leading suppliers have lost some market share .

In contrast, in 2012 won a place in the market are the main suppliers of the vast majority of medium-sized enterprises in emerging markets . 2012 , the market share of more than 1% of the number of suppliers increased to 24 , this new group contributed three-quarters of total revenue . "The majority of market share and ranking rose suppliers are those in the fast-growing emerging markets in-depth plowing or launch the latest technology enterprises.

2012 , AdvancedEnergy with Enphase two companies in the fast- growing U.S. market in a strong position to promote increased its global ranking to fourth and sixth , and in 2011 the two companies were ranked eighth and eleventh names . Similarly , Omron advantage in the Japanese market sales charts it won the sixth position , and became into the world's top ten list of the inverter supplier first Asian suppliers .

In contrast, three inverters supplier fell out of the 2012 global top ten ranks. Following financial difficulties after , Satcon declared bankrupt ; Siemens exit the PV industry , and will be attributed to the decline in growth and increased pricing pressures ; Sputnik Engineering is rare except in the stagnant European market for new markets .
