Incinerating toilets and mini-split air conditioners on solar?

Has anyone here ever had success running either of these in a solar-powered off-grid structure?

I've seen and read several sources/product reviews that advise against using each of these (especially incinerating toilets) with a solar setup, but I've heard anecdotes from a couple of people who used a dedicated solar panel for a mini-split and had no problem.

I think an incinerating toilet is the best option for my location, but I'm not sure if I can swing it off-grid.
