If I had your problem the first thing I would do is check the battery voltage, with the furnace off, first with the 120v unplugged then with the rig plugged in. The voltage should increase with the rig plugged in. Exactly what it should increase to depends on your converter and the battery state of charge.

Lacking a volt meter, have someone plug in the rig while you watch the lights. They should get brighter when plugged in.

The next step depends on the results of this test.
