Any AC appliances you run will reduce the power available for charging. The inverter doesnít create power out of thin air, it just converts it from DC to AC. The source of power the tow vehicle alternator, same as the 7-pin connector.
At full load, your 10000W inverter will draw 75-85 amps DC from the tow vehicle. Yes, thatís a lot more than the 30 amps available from the connector, but the connector goes straight to the battery, eliminating the energy loss through both the inverter and the trailer power converter.
In addition, the total AC output of your 1000W inverter is 8.3 amps, about half the capacity of a standard 15 amp AC outlet. While you could conceivably run a small microwave or an LED TV, most of your AC appliances are too big to power from the inverter. A typical water heater takes 6 amps, a refrigerator on electric is around 8, and a 13000 BTU air conditioner takes about 16 amps, twice what the inverter can provide. And whatever AC you use takes away from charging the battery.
