[RE-wrenches] Enphase/Conergy Suntop and Weeb

[Nick Soleil]

Hi Benn,

I manage the content on Enphase's Racking Compatibility List and WEEB List,
and have worked with the engineers from Wiley (now Burndy.)  We have tested
the Enphase microinverters with multiple configurations of WEEBs and
racking types, and the ground is adequate with 3 of the 4 tabs making
contact between the microinverter and rail.

The Conergy SunTop / CMC / M215 is not the only pairing where this occurs;
it occurs with most pairings.

Don't worry about this one.  It is fine. No additional steps should be
taken during the installation process to try and prevent this.

What is more important is using a 1-1/2" fender washer to spread out the
clamping force applied to the lid of the M215 microinverters.

Feel free to reach out to me directly if you have any questions or concerns
(my contact info is below.)

“Don’t get me wrong: I love nuclear energy! It’s just that I prefer fusion
to fission. And it just so happens that there’s an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it’s wireless! .”

- William McDonough
