Anyone have any info on this (recently UL approved) Sharp grid tie inverter?

Supposedly the units have > 60,000 installed (out of the country - mostly
Japan?).  They sound sort of like the SMA SunnyBoy units (in that they
configure with higher voltage series strings) and support up to 3 separate
strings.

One (reported) unique aspect is that each of the 3 strings supposedly do not
need to be the same configuration or orientation & the unit has a higher
efficiency rating that anyone else in the game... I'd love to see that!
Frankly, I've yet to hear it from an unbiased source...

I, for one, welcome our new inverter overlords.

 Until I get my hands on one at the training in So. Cal , I'm reluctant to
rely solely on the the PR and skimpy datasheets put out so far.
Personally I think Sharp are being smart to insist on training and
licensing.
But what I can confirm for you Roger is that , yes, up to three dissimilar
high voltage strings can be connected.
This helps in a number of ways including handling multiple planes ( where a
roof surface is fragmented ).
Also, the Sharp residential "brand" includes some newer poly-silicon panels
whose electrical characteristics are matched to allow easy mixing of those
panel sizes ( co-ordinated triangles and rectangles ).
Efficiency rating is no higher than our other favorite , but the reported
de-rating characteristics are rather interesting ( = good ).
