I posted a similar thread before here and oddly I had the same experience. Lightning tonight in the area. After one of the strikes made the UPS's beep, I switched the PW to self powered and they started supplying the house. Less than 10 minutes later, the area power went out right after a strike. Items plugged into the wall such as TV, cable box, amp, all lost power. The last thread suggested this may be normal, but since that thread, there's now a "go off grid" option in the app. Since the cutover is not clean when on PW, should I have selected that option instead of "self powered"?
