<p>Hey Marco,</p>
<p> I hear you, we have installed many SMA-40's and we're
not at the same point as you may be but we've definitely had a
fair number of arc fault shut-downs which take a site visit to
rectify. One location had been experiencing lightening over a
year and a half which seemed to be triggering the 8206 code. <br>
</p>
<p> I had to go back three times to one such install.
After that I went back with my array map (before an install I make
a laminated map of the strings with home-run locations) and
started inspecting home-run connections. I was lucky and found
the culprit with my first try. Somehow I hadn't pushed the wire
end which I had crimped on the tip to far enough into the plastic
connector....too cold maybe? lazy? distracted?...not sure but
there it was, my bad. I took that connector back to the shop and
sure enough it would show intermittent connection with an ohm
meter, perfect for an arc fault.<br>
</p>
<p> This doesn't answer your question about the fix but
thought I'd apply a little egg to my face in the hopes of saving
others the same.</p>
<p>Bill</p>

Aloha all,
