The premise of One Second After is an EMP attack. Suppose that would be like a major Carrington event.

The March 1989 solar storm shorted out the Quebec power grid for 9 hrs. 9 days would be testing the veneer of civility.

Not exactly correct. The premise is a Nuclear EMP, not a solar. they have their own characteristic. A solar can be planned for and much damage prevented by unplugging stuff and shutting it off. A nuke EMP doesn't care and will fry it anyway.
