Rebekah:
Thanks for your help with this. Because I snapped up all of the 100 series rack I could (pun intended), I am past the recertification with newer modules. My argument is that although the rail was discontinued, the clips remain. What I did is extracted a page from the UR series manual showing testing with the Mission panels and inserted it into the permit set. I hope this sleight of hand passes plan check.

I wish there was a reasonable workaround for AHJs here, like onsite resistance measurements.

The UL 2703 listing requires the two to be tested/listed together for the rack to functionally ground the solar panels. [CEC 690.43(A)] Alternately, bond the metal parts of PV equipment to grounded metal supports per CEC 690.43(B).* Is it true that UL2703 requires testing with each and every type of module? I am using 100 Series rail from my stock with Mission MSE325SR8K panels. Does anyone have any documentation on file that would satisfy this request? I have sent an inquiry to Snap-n-rack about this but they often take a week or more to respond. Thanks in advance.
