My initial reaction to your posting was "What??!!" But, I see that I have used the wrong terminology. I stand corrected.
What I have purchased is a Progressive Dynamics Power Control Center. I used the term "converter" in the generic and I see that that is incorrect.
At any rate, take my earlier post and substitute "Power Control Center" for where I said "Converter" and you should be AOK. Yep, the converter is simply that portion of the power control center that "converts" 120v alternating current to 12v
direct current. As opposed to an "inverter" (which works the other direction....like you'd find in an ambulance) that inverts 12v
dc to 120v ac current.
OK, so all that being said, remember that Watts = power and that amperage times voltage = watts. So, if you are restricted to 120v ac, if you want more power, you need more amps because the voltage doesn't change. Hence the ramp up from 30amp to 50amp. Even though they call it a 50amp, the power control center (not a converter
) says 55amp on it.
Anyway, you will most likely need 50amp service to run two a/c units. But I still say that if you paint your roof white and get a good 15,000 btu unit, you could get by on 30amp. Just can't run the a/c, the microwave, and a hair dryer at the same time.
See you all on the road!
