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.
