It is not about a prediction. It is about the question whether the sizing fits the scenario. 3 days of power outage and a 5 kWh battery do not go together, you really have to go big.

Exactly that. Either do it properly so that you can bridge multiple days or not at all. Providing power for 2 or 3 hours is nice, but nothing more.

I would rather take camping equipment (stove, lamps, propane gas heater) than batteries for so much money that I never need. It is significantly cheaper €/kWh. And boiling water is easier and more sensible with that than with electricity. Ideally, you have a caravan - they also have gas-powered refrigerators, but that will be the smaller problem in winter if there is no power supply. Otherwise, a mobile photovoltaic system, a suitable charger, and an e-bike battery that is not restricted. You can also connect everything up to 36V or, if necessary, 220V devices via an inverter.
