I did the math of how little power I would need to cook for a few minutes each day, and concluded I could use inefficient electricity to cook with and still have plenty to run the fridge and fan and lights and charge a phone...
In theory, yes, but when drawing huge amounts of amps like for an electric burner, a small complement of batteries can't maintain enough voltage to keep the inverter online. I'm not sure what kind of electric stove cooking is done for a 'few minutes.' Frying eggs?
