[RFI] Solar Edge Prototype Optimizer

[David Eckhardt]

Ed, I'm well aware of the regulatory requirements and the fact that the
"full-up" system can not be properly evaluated in an accredited lab.  I can
only hope.  It sounds like you/ARRL are the best bet for evaluation of the
"new" optimizer unit.  I wish you and SolarEdge luck!

Please let us know how it turns out.
