The added efficiency of a DC variable speed /inverter setup comes from its minor load ability to match the engine HP to the load.

Running at almost full bore the fuel burn would only be slightly different.

The mismatched installation a 12KW running only the fridge would be helped.

Some folks could do better using the noise maker cooling thru the heat exchanger to create domestic hot water.

Co generation , capturing some of the lost energy for free.
