Thought, research, calculation, then feasibility study.
Induction cooker :- up to 2000 watts? maybe/likely less? but lets work on the worst case.
2000watt Inverter :- There is peak watts and run watts, items can have a peak for a short period, but run consistent at lower than the flashy number printed on the box? So? Will a 2000watt inverter run a 2000watt cooker?
A 1000watt inverter will run on cable the size of your little finger, a 2000 needs close to the size of your thumb.
How much Ah ? Well the ball park is divide AC watts of the appliance by 10 to get DCamps draw, therefore 2000 divide by 10 = a massive 200 amps dc?????? Sounds horrific, don't it? At the least it could be as low as 160/170 amps as calculations of dc/ac vary.... and yes I don't give a rats ring about inefficiency or losses.[remember, I DO NOT let my tyres down!]
Next, cook time? 10 minutes? or half an hour? Lets pluck 15 minutes out me ****[insert sound fx], and go with it. That's one quarter hour, remember Ah from above? Well that's amps per hour. From the previous rubbish I plucked out me ****, we need 200 amps per hour divide that by 4 for 15 minutes, bingo 50Ah used to cook for 15 minutes? On hand we have one 80Ah battery minus 50Ah in fifteen minutes, and I predict we are going to be in tears, today or tomorrow.
One can work forward and backward to estimate the battery capacity/solar/battery/angst/or tantrums ... oh solar .... yes ... one just destroyed 50Ah in fifteen minutes, no matter if we have 80 or 800Ah battery, it needs to be put back. So? The solar needs generate 50 amps over 1 hour of ''peak'' sunlight or 5 amps over 10 hours of peak sunlight. A 120watt panel may max out round the 7amp mark [again insert sound fx, I plucked that out me ****] great, 10 hours of peak sun? no ! ....... Lets pluck out 5 to 6 hours 9am to 3pm? Six sevens are 42, close enough, six by 120Watt panels makes.... [lets just buy a freakin gas bottle, or go the pub]
Disclaimer:- I plucked some or all out me *****, I don't care about totally technical b&s of units per hour per hour, losses, mppt, lithium charge rates, zebras crossing the Zambezi river, it's not needed when the feasibility study get screwed up and binned after all that twaddle.
