Pulling 100 amps through an inverter would keep the DC-DC converter at max, poss overheat/failure, etc.

#1 the DC/DC converter is
liquid cooled and that is what the second yellow tank of coolant is for under the hood.
#2 The FEH has
MORE 12v devices than a traditional car. The 12v coolant pump is just one example. It has more actual devices... but I can't be sure this means more amps overall.
#3 If you run your headlamps / parking lamps, fans, etc... then obviously you will have less current available to run your power inverter.
#4 If you turn on every possible option in the car, the 12v draw is about 100 amps... and the car can sustain this indefinately.
