[RE-wrenches] SMA phantom arc faults

[drake.chamberlin at redwoodalliance.org]

At least with the TL-22s, the AFCI function can be turned off. You
need a_ Web connect speed wire module_. .I don't know if this same
protocol will work for the TL 40s or not.  

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.

 Aloha all,

My company has really been struggling with the SMA US-40 line of
inverters and incredibly disruptive to positive customer experiences
bogus arc faults. 

We were told by our SMA friends that a firmware update/fix was
forthcoming in mid-August and we’ve heard nor received nothing last
month.

Does anyone know anything as to where they’re at on this?

Really frustrated....
