One issue to remember is your 3 way is no different than a light bulb if the voltage drops by 10% then the light bulb dims. So your frig element gets less wattage. Which is why so many ppl complain about performance on 12v.... if you have a 12v regulator that does 13.8v then you get consistent wattage.
Correct, but in this test the 240v element draws less juice than the 12v element. In both tests the battery voltage remained about the same. By all accounts the fridge should cool better on 240v, and in my tests, using less energy even factoring in inverter losses. That leads me to believe the 240v heater is positioned better to make more effective use of the heat it generates, despite pulling less power.
