replacement air conditioner
I want to replace my rooftop air with a mini split cassette like the one in the attached video. https://www.youtube.com/watch?v=aDXKuZaMXoY My plan is to run it on solar and batteries. Problem i...

I would go with a 240 volt sine wave inverter dedicated to the mini.
I like separate components but get a combo unit for the 120v if you must.
Yes Victron makes inverters that can be connected to make 240/120 split phase service. I think in the end this would make it more complex.
Yes, Victron makes inverters that can be stacked to make 240V split phase. They still recommend an Autotransformer on the output side to load balance 120V loads across both inverters (though most RV installs seem to skip this - I don't recommend doing so) and if they are stacked, then if you plug into single phase service the second inverter will reject the input because it isn't out of phase and thus, only one inverter will be used for charging. If you run ESS, then both inverters will reject the input. To work around this they make - guess what - an Autotransformer.
In the end, the best solution for the user here (assuming the rig is 30A) is probably a single Victron inverter and an autotransformer in the role I initially explained. Everything else is over-complicating things for no benefit.
The Autotransformer consists of a couple windings and a breaker. Not much to go wrong with one and the MTBF is >100 years.
