12v is for when you are experiencing to use about 2kwh per day or less. For backup power for a refrigerator and a few small items or camping because of the 12v.
Cars only have about 10 amps available for charging with everything off, idling. Burning a L of gas per hour or more for 10 amps sucks.
A 24v alternator strapped to a 3hp predator engine can do better than that, a lot better.
