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.

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?
