None of it will matter. That said, short term FUBAR can be mitigated. I have a semi-portable solar setup that currently runs my internet, NAS, Fridge and to some degree, the A/C.
To prep for the serious mess, I have to get Faraday bags for my server, drives, and solar generator and have enough time to bag everything before the EMP hits.
I have survival guides in book form as well as on the NAS, and I work the land enough to bring the soil into balance and build its fertility, plus feed the bees so they’ll be there when I need them.
Not huge. I have a bluetti AC200L and 1000 watts of mismatched panels. It’s plugged into the wall socket and switche to grid power at 40% of capacity.
Router and modem plus NAS average a continuous 70 watt draw. The fridge is the biggest draw as it turns on regularly and uses about 80 watts, and runs a defrost cycle for 40 minutes at 300 watts.
