It's all about total amps. If you are on a 30 amp main breaker, then you need to limit your self to 30 amps.
You may think that is the only two things...but is the fridge using AC 120 volt, how about the water heater, and how many 12 volt things (lights, pumps, fans, etc are you using. The 12 volt things are powered by your converter which converts 120 volt AC to 12 volt DC. The more DC things you are using, the more AC amps the converter is using.
There should be a label on the bottom of the coffee pot that tells amps or wattage. You can convert wattage to amps by this formula
watts = voltage X amps
Ex: 1440 watts =120 volts X 12 amps

Hopefully, it's just something as simple as overloading the circuit which you can easily correct by turning things off, but it could be something else.
Can you turn the coffee pot off, and everything else running is good to go?
If so, then can you turn off the air conditioner, and everything else is good with the coffee pot going?
