Non tied solar won't affect the grid at all. So this is a non-issue.
Grid tie requires the grid to tie to, otherwise it can't synchronize. So it stays disconnected.
Why would that prevent you from being grid-tie? I have 53 panels (~21kw) grid tied and pushing to the grid, but in the event of grid failure my panels will still operate and push into my 42kwh battery array which will power the entire house. ( The batteries take over as the 'virtual grid source). I can then augment the batteries with generator and run fully off grid for an extended amount of time ( weeks in my case ).

these are mutually exclusive. What you have is a hybrid system, which is something i explicitly did not mention. A grid-tie system is not generating an AC waveform when the grid is down, at all. it cannot, by definition, and by design, as the AC waveform requires the grid to synchronize to.
Hope this clears this up.
I really thought that sentence was going to end with "it makes it a lot easier to handle that segment".
Yeah you have some big problems if it's a complete surprise, but your status quo monitoring would have to be very strangely broken for it to be a complete surprise. Instead it should be a mild complicating factor while also being something that reduces your load a lot and lets you get things running quicker.
You need to calculate for it but I don't think this would be a problem
The South Australia System Black in 2016 would count - SA already had high wind and rooftop solar penetration back then. There's a detailed report here if you're interested:

Also I suspect there is far more renewables on the grid now than in 2016.
This is potentially the first real black start of a grid with high renewable (solar/wind) penetration that I am aware of. Black starts with grids like this I imagine are much more technically challenging because you have generation coming on the grid (or not coming on) that you don't expect and you have to hope all the equipment is working correctly on "(semi)-distributed" generation assets which probably don't have the same level of technical oversight that a major gas/coal/nuclear/hydro plant does.
I put in another comment about the 2019 outage which was happened because a trip on a 400kV line caused a giant offshore wind farm to trip because its voltage regulator detected a problem it shouldn't have tripped the entire wind output over.
Eg: if you are doing a black start and then suddenly a bunch of smallish ~10MW solar farms start producing and feeding back in "automatically", you could then cause another trip because there isn't enough load for that. Same with rooftop solar.
