According to the website, the base model is 7kwh (7000w-hr) battery bank and 600w solar.

If you are doing long 6-8hr slow simmering meals, it could be a bit of a problem.

Assuming the stove uses 1500w for an hour on high (longer than it typically takes us to make most meals, that's pretty viable with a 7000w-hr battery bank. The 600w solar system should put back in around 2400w-hr per day.

Our 12v fridge pulls around 60w on a 50% duty cycle in comfortable conditions, so around 720w-hr per day.

It's when it gets hot or cold that battery power becomes problematic. An air/con pulling 1200w with a 50% duty cycle is going to pull 14,400w-hr per day. Assuming they are heating with a heat pump, expect similar consumption. So it would need a substantial upsizing to the battery bank and solar array to keep up or they need to undersize it but then the duty cycle goes up. If it's small and insulated far better than I expect, it might be possible but you will always have to be watching the batteries so you don't run them dead.

None of what you're describing comes anywhere close to meeting the definition of "indefinitely".

If there is no sunlight available, no amount of solar panel "upsizing" is going to help.

You are going to run out of power.

Interestingly, they don't list the cooling capacity in BTUs - Only in "watts of cooling power".

If you use the standard conversion factor of 1 watt being equal to 3.41 BTU/h, their larger "Comfort RC" model with "2400 watts of cooling power" produces 8200 BTUs - Which is around 60% of what a typical RV air conditioner produces.
