[RE-wrenches] Solar power Magic

[David Katz]

Bob-O
I see a use for SolarMagic from National Semiconductor in large systems=20
with many parallel strings, installed by inexperienced contractors who=20
put some of the strings in the shade, not realizing how little you  get=20
with minimal shading of one string in parallel strings of modules.  They=20
might have to buy these to appease the system owner who is not getting=20
what they expect from their system.
They Tigo converter is very interesting and has an MSRP of $56.  At this=20
price it will make some sense.
Cheers,
David
