A pallet of cheap, used solar panels, two large inverters with required control units and batteries for a “power wall” stored in a metal boxes is a good start. Said metal box needs attention to make it into a faraday cage.
That would survive a large EMP event. Just don’t take them out for a few days because weaponized EMP pulses mean a scenario where there would likely be more.
It would suck to set up your emergency generation/storage just to have a subsequent EMP pulse damage your ability to generate power.
A deep well pump usually requires up to 6kw to start and run and I consider having water to be the most important for survival. A working well pump is usually not easily identified by outsiders because most deep well pumps are silent.
During a long blackout event (one month or more), don’t flaunt that you have power because the “have nots” will surely be attracted like a moth to flame.
It’s hard to conceal solar cell arrays and generate power with them.
It’s best to present a “we’ve got nothing” view to society until law and order are once again established.
If power goes down in a nuclear attack scenario, there really would be no safe haven much like in the movie “on the beach”. Not sure how Fred Astaire ended up in the cast of a disaster movie but he was also in “towering inferno”.
