a 30 AMP Breaker will give about 3,600 watts ---- if it is working right and others are not all running their ACs and the voltage is low.
But starting there
Take away what your converter is using to recharge your batteries. This will drop as they reach full charge but the converter will still use some power to run lights, fridge board, etc. Just guessing 200 watts?
Then look at what is running
Residential fridge?
Microwave
TV
Coffee pot
Etc.
You may have enough to run one AC but not both.
Get a handle on how much you are using either by adding it up or by getting a monitor to prevent low voltage or blowing the breaker.
