If the inverter has a split bus I don't think it would limit the power.
in normal operation each bus is subjected to alternating 8ms of loading,
I donít see why one can't constantly load one of the buses, but you
never know.
The AC DELCO inverter I have looks robust enough (multiple parallel
transformers for each bus) to pull this off.

You do need to check regulation, since MSW inverters adjust their AC
output pulse width to maintain 115v.
The bus is the output of just a raw DC-DC converter with no regulation.
But a good thing is there is most likely some form of circuit protection
(Over current) built in, at least one would hope.

Cheers

Since Tecumseh went bankrupt last year, who bought the name and is
manufacturing the equipment under that name, so that they can sound more
legitimate. It certainly isn't the Tecumseh we remember.

 Hey,  I have gone down this rabbit hole. Kingtec Solar air conditioners hav
e been developed to do what your talking about.

It's more than just a compressor.  Here is a description of one of our prod
ucts.

 Solar window unit description:  16000 btu -- E.E.R. 18.6

Kingtec Solar air conditioners come completely ready with built-in connecto
rs for solar panels, power converter and batteries. All the necessary cable
s are provided. The A/C has a 45 amp mppt solar charge controller inside th
e unit. There is an external enclosure for the AC to DC power converter opt
ion.   All of the necessary DC overcurrent protection fuses and breakers ar
e installed in the air conditioner. Quick fuses for solar surge protection  
 and grounding are also installed in the unit.  The air conditioners come w
ith two year warranty on parts and one year on the compressor


So - How much did you say you were willing to pay?

Not that much!  At least, not yet.  That thing (not even counting the PV  
panels) would cost us what we pay for two years of power bills for our  
whole house, yet the compressor is only warrantied for one year!

A conventional unit powered by an inverter might make a lot more sense.
