Professor Frede Blaabjerg too inverter
which several review articles have reached nearly 1,000 reference number, which
in the field of power electronics has been astonishing. And when he was the
IEEE Power Electronics Technology (Transaction on Power Electronics) editor in
the past few years, the PV inverter has become a very hot research field.
Personally, I think the article is very
accurate prediction, since 2008 Enphase company introduced the first commercial
product, the micro-inverter begins to be academic outsiders who know the
company by virtue of its advantages in Silicon Valley development is very rapid
expansion financing fast, then quickly followed several other brands compete.
First, wait several major brands, recently began the layout of the
micro-counter market.
Industry leader SMA bought the micro
inverse Pioneer OKE-Services product platform OK4ALL, and thus developed a
micro inverse products SunnyBoy 240. This product is currently only available
in the United States of SMA website you can see, the specific time is unknown.
Power One also in 2011 launched its own micro-counter products Aurora Micro.
Micro-inverse can improve system
efficiency, since each module is equipped with an inverter, the mismatch loss
between the components (mismatch loss) can be eliminated. However, due to the
inverse price higher than the current micro-string grid tie power inverter times, even if the
total generating capacity of slightly higher cost of repayment of the system
time (payback time) also no advantage.
In fact, there is an inverse micro big
advantage is that installation is easy and safe to do, according to some of the
PV system design UNSW alumni, currently the latest Australian standard AS 5033
installed PV installation on the micro inverse relaxation of many requests, but
due to the voltage levels decreased, workers feel more secure installation.
This may be the future of this technology to develop new markets major
advantage.
