fridge electric heating element 345w, 3amps at 120v
but thats 30amps at 12v input into the inverter..
your 1kw inverter is No problem, but your batteries will only last a few hours
the fridge uses 12v control circuit, but that very small only 1 amp , unless there are fans on the cooling unit
switching from electric to gas on power failure it will last a long time on batteries and propane
but propane fulltime is best, then if shore power fails, the only drain on batteries is the 12v control circuit and the fans..
like i said a long time.. days..unless there are 12v fans involved
even then it will be many hours
