Hi Tim:

If the inverter is really delivering 1100 watts to the oven then = it is=20 drawing 85 amps or so from your 14 volt system (over 100 amps if the = voltage=20 falls to 11 volts). Suggest you check carefully if the wiring/breaker = and=20 engine monitor are both up to that current delivery. You will = obviously run=20 the battery down fairly quickly even if the alternator will support 60 = amps=20 continuous.
