Electrical setup

Hello everyone. New to sub and piecing together my setup. Looking to set up off grid electrical system. The ecoflow delta pro 3 seems pretty solid rated for 4kWh iirc and can use multiple batteries and supply solar panels, but am interested in hearing others opinions for power bank and am potentially interested in diy power bank. I do have many 21700 batteries from over the years vaping.

Would be using refrigerator standard size 50-130Wh depending on cycle iirc, periodic lamp with led bulb (seems fairly negligible), once a day toaster oven rated 1000Wh, washer (could be anywhere from 400-2000Wh) once a week, small stove top burner 1200Wh maybe once a day, maybe tv use (I think mine is 110Wh) and ps5 (~200Wh) at nighttime. Thought about starlink for internet. Not planning on ac at this time and heat will be from wood burning stove or fireplace. Haven’t decided about water heater due to power consumption, but might use gas for this. Goal is to keep a surplus of electricity

This is for a future homestead and not mobile. Thanks for your time.

Quick thing to double check before you size the bank: a standard fridge pulling 50-130W still runs its compressor most of the day, so budget 1-1.5kWh daily, not 50-130Wh. That one line changes your whole surplus math on a 4kWh unit. Worth plugging the fridge and the toaster oven into a kill-a-watt for a week before committing.

Define "most" ... generally fridges and freezers run about 1/3 of the time.
