<p>Interestingly, the problems I've had with the SMA -40 AFCI faults
have been on Comp roofs. When I've gone "inside" a -40 with my
laptop, I'm pretty sure I've seen where you can disable it?</p>

<div>At least with the TL-22s, the AFCI function can be turned
off. You need a<i> Web connect speed wire module</i>. .I don't
know if this same protocol will work for the TL 40s or not. <br>

<div>Metal roofing can apparently be affected by radio waves and
by other factors that create a disturbance that can trigger the
AFCI.The TL 40 was supposed to overcome this problem. <br>

[RE-wrenches] SMA phantom arc faults<br>
<br>
<br>
Aloha all,
<div><br>
</div>
<div>My company has really been struggling with the SMA US-40
line of inverters and incredibly disruptive to positive
customer experiences bogus arc faults. </div>
<div><br>
</div>
<div>We were told by our SMA friends that a firmware update/fix
was forthcoming in mid-August and we\u2019ve heard nor received
nothing last month.</div>
<div><br>
</div>
<div>Does anyone know anything as to where they\u2019re at on this?</div>
<div><br>
</div>
<div>Really frustrated....</div>
