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

I am afraid my 60 amp alternator is not quite up to th= e job or should I just install a heavier circuit breaker? The oven is label= led "CE 230v 1080w".
