I'm a photographer and filmer.
In a petrol-based car I sometimes use the car with a 12VDC to 230VAC inverter and run the engine.
I think it's better emissions control than a portable generator.

How does the 12VDC system work in the ID.3?
Is the 12V battery continuously charged from the main car battery if the "engine is running?"

Or is it a traditional generator/alternator that charges the 12V battery while the car is on the move?

There is a converter that takes power from the high voltage battery to charge/maintain the 12v battery; there is no generator.

The 12V battery is charged as needed from the main car battery even if the "engine is not running". This was added in a recent update since the early ID.3 were having dead 12v batteries too often when just sitting parked, due to a low drain but always on portion of the electronics. You should be safe to run your inverter.

You can draw power from the 12V system while the HV system is powered on (car on).
I don't know what the power limit of the DC-DC converter is, but it could be a few kW in order to power the heater.

I have a 1500W inverter hooked up to the 12V battery on my Chevy Volt and it works fine on that car.

Perfect, then there isn’t any need for a mobil generator when working in the field.
The power from the fuel car 12V system worked fine.
