Yes, a battery stores energy (how much is determined by the size). Multiple batteries store more energy.
An inverter does not "turn the power upside down". I agree that there can be less line loss at 120v than at 12v, but that's not the goal. The goal is to power a device that was designed for 120v.
I absolutely guarantee that you can run your AC by improving your batteries and inverter to the necessary level. A residential fridge takes a lot lower "necessary level" and that upgrade is commonly done.
I have a cabin with a total solar electric system, and have for 10 years. I'm well aware how how independent power works.
Since a decent, small, system costs $20,000, and my batteries are enormous, please tell me how I can run my AC and fridge in an RV by "improving my batteries and inverter". Where do I get these items, and how much do they cost? How much do they weigh? What is their power source?
To turn inside out or upside down: invert an hourglass.
