Did the ARRL lab have influence on the re-designed version that is in the supply chain? 

I was presenting at a club last week and I was asked about the Lab working with some manufacturers on devices that had interference problems.  I was asked about the prognosis of that actually being effective.  I told him I would do some checking and get back to him since I didn’t have a good answer on the spot.  I dropped Kermit’s name and the EMC Committee, along with the ARRL Lab in that conversation.

If the ARRL Lab did have some influence, is that something we can share specifically?

Hello John -

                THe manufacturer is Solar Edge,  I also believe that they

are the OEM of the problematic optimizer circuit.  A re-designed version

is in the supply chain and the problem that their system presents can

be remedied - but with PV systems becoming a cottage industry (especially

in California) we will need real-time input from the field to keep harmful

interference problems in check.  The important take-home from the

Solar Edge story, is that industry really worked well with the ARRL lab

(Mike and Ed)  to solve the problem.

                 We are starting a cloning process in the lab, but we aren't

supposed to tell anyone.

                Thanks for the kind words, I will pass your message along to the

Committee.  See you in a few days !

                                      GUD DX es 73,

                                                        -  Kermit W9XA

    Who is the solar products manufacturer discussed under "Solar PV Systems"?

    And — please — could we all agree to number the pages in our reports to make it easier to discuss them? T

    What plans do we have to clone Mike Gruber or find a suitable replacement?

    Kermit, thanks to you and the EMC Committee for the extensive work, by the way.
