    On loss of power these inverters cut off within 20 ms or so. These are grid-tied, not insular (though with hacked firmware some of the models can be made insular-capable).

      20ms are exactly 1/50th of a second i.e. our grid frequency I think there’s some more leeway. A whole oscillation being gone surely is suspicious and you want to shut off but that might take another millisecond or two.
