Not really, but depends on the state of the infrastructure, if it was really because of a power overload, yes, but most likely "your circuit" (which could be your street or your neighborhood) got shut off, in this case there shouldn't be much difference

Yes, a phase difference of 180 can definitely happen but I guess most electronics can survive a 1/60s (I'd say even 1/10) switching time, which is probably enough to have the grid take over.

(Or of course you could have the grid and solar charging batteries then your own high power inverter for your house but that of course would mean $$$$$$)

A 1/10th switching time would be fine though if you change phase too much and suddenly some equipment might not like it.

And you'd still have to sync the inverter, having the inverter simply continue to run until it's back in sync with the grid, then just reconnect (as a previous comment wanted) is likely not an option for most consumers.

For that it would likely be cheaper to have a full DC stage as you mentioned.

Most computers can't handle 100 ms power loss, unless you actively throttle power consumption as soon as you sense the loss, in order for the filter capacitors in the PSU to last that long.
