An undersized extension cord, poor quality adapter or a weak breaker at the house could be your problem. Is the tripping breaker a 15A or 20A?
If your battery is starting to short from age it can cause the converter to draw excessive current without you being aware.
A true 1500W heater will draw 12.5A at 120V plus a small fan current, but mine draws ~11A
