PV inverter market recently after several
mutations, April 22, ABB came news of the acquisition PowerOne vibration
industry. People have speculated that the electrical equipment giant and the
world's second largest manufacturer of photovoltaic inverters marriage of whatchanges will bring the photovoltaic industry.
With the major components of the market
giants leave the flesh is different inverter market is indeed acquisitions
frequently. In early April, the Photon magazine was a very eye-catching German
inverter manufacturer REFUsol by U.S. companies AdvancedEnergy acquired late
last year, the acquisition of the domestic industry a brother SMA cable
manufacturers MeV love. The major manufacturers in the direction toward the
bigger and more powerful strides, coupled with China 's western photovoltaic
"leap forward", some domestic manufacturers that "one hundred
kilowatts below the small loom we simply do not do it."
Compared with the component, the inverter
technology innovation more slowly. Especially large inverter
(utility-scaleinverter) each topology (topology), control methods, switching
devices are similar, but the stability of the product and the actual efficiency
is need long-term experience in engineering design. On the other hand,
large-scale projects also need to do this kind of technical support for
localization, marketing, government relations, financial support, the future
winner in doubt, but the multinational giants have been ahead of others in
several ways.
But it is an entirely different story in
academia, laboratories inverter is getting smaller and smaller. Engage in
research of PV inverters should have read Danish Aalborg University
FredeBlaabjerg professor and his students to write about the PV inverter
(PVinverter) review articles.
The article mentioned the inverter a trend,
a large central solar grid tie inverter (centralizedinverter) is already very mature past
tense, then (2005) is more popular string type (stringinverter) and
communication components (ACmodule) / micro-inverters (micro-inverter), the
future trend will be the exchange of components or even AC battery (ACcell).
