Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear
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.
