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.
