The PV on the roof probably wont help anymore after am EMP. So you‘d need the whole package incl water purifier also in a shielded box

I think the PV would be fine, but the charge controllers, anything that uses a coil, might be fried.

EMP's create huge discharges in coils, that's how they "fry" electronics and cars and motors and the more sensitive chips attached to said coils.

yep, and the magic number of separation of condenser plates to a solar water condenser is 5mm.
