Generators: Do the proper break in procedure and keep plenty of oil on hand. Do not run a brand new generator out of the box like a broken in one. Change oil every 100-150 hours. Do not use eco mode. It causes carbon build up. Don't waste time and money on shit generators. Honda and Onan/Cummins are about the best. Stay the fuck away from Champion and Predator. Use marine stabil, the blue one every tank of fuel.
AC: Get a window unit or portable AC and wire in a microair easystart to it. This will allow you to run at least one room worth of AC off of a generator. I can run my 6k btu on my little Honda 2200, though I usually run it on my Onan 4500. Compressor appliances like AC and refrigerators are hard on generators and require high current to start unless a third party start assist like the easystart is used.
Power: Solar panels, mppt charge controller, batteries, inverter. You got some homework.
Water: Two gallons per person per day minimum. Know local water sources of available. If not available, move.
Food: Dry goods that only need water added. Grains, pasta, etc. Canned and jarred goods. Eat what you store and rotate products. Be mindful of rodents and humidity. Be extra mindful of anything dairy like jarred Alfredo sauce. Tomato based sauce lasts much longer.
Cooking/hot water: propane 21,600 btu per pound. Know your burn rate. Store 1lb bottles or put up a bigger tank with a conversion kit/hose for whatever propane appliance of your choice. I like the Coleman two burner stove personally. Be mindful of the excess moisture produced. Blue flame is safe. Yellow is incomplete burn and will produce carbon monoxide.
Never use "off grid" electricity aka battery bank and inverter to power anything that converts electricity to heat or drives a compressor. Making heat from electricity is the worst use of electricity. Your 2250 should have ran your fridge/freezer unless you used an extension cord that was an improper gauge or was too long.
Being prepared isn't just hoarding and living on cheap Walmart camp equipment. It's a lifestyle. Use what you put up, rotate, replenish. There's no reason I'm more prepared in my van than you are at home.
If you don't have wood, water, and game in your area, move.
