You say you are plugging into the house. How many amp circuit are you plugging into? A 15amp circuit will not be enough to run your air. Stop trying until you have a 20,30 or 50 amp circuit. Even with 20 amp it will be hard to do if the converter has kicked on to charge your batteries. Turn off converter breaker.
You can avoid reality, but you cannot avoid the consequences of avoiding reality – Ayn Rand
