Phantom 4 amp inverter draw - Help please

I recently installed a 2000 watt inverter which draws 1 amp or less when turned on with nothing connected to it. When I plug the shore plug into the inverter (converter/charger unplugged and fridge on LP of course) There is a 4 amp 12 vDC draw from the inverter with everything I can think of unplugged or or disconnected on the AC side.

Is there anything else in the 110 vAC system that could be drawing 4 amps from the 12 vDC side of the inverter. Tank heaters, lights or something else I am missing???? The list of items I have disconnected from 110 vAC is below...

110 vAC Unplugged or Disconnected:

  • All outlets
  • Fridge
  • water heater
  • microwave
  • converter/charger

110 vAC still connected:

  • Air Conditioning Unit

The air conditioner controls are a possible draw. I have seen it with my Armstrong air conditioner. There is likely a 110 to 24 volt transformer in there that is hot all the time

Turn the AC circuit breaker off and see what that does. Report back. I can't think of any other load you have missed.

Turning the circuit breakers off one at a time should give you more to go on as to which one is causing the load.
