Automobiles and motor homes have a 12 volt electrical system. Conversion buses have a 24 volt system. Maybe high line rigs like the LADB, KADB, EXDP and MADP should be 24 volts. I realize this is more a chassis issue, so K-2 or at very least K-3 Spartan chassis's.
As this is a topic I'm going to write on in early August, I thought it would be great if I could get some helpful input on the subject.
Especially the K-3 with its soon to be 650 HP. The starters would operate at half the amperage and the cables would only be again half the size. After all, large engines generally come with 24 volt starters for that reason. My boat, for example is 24 volt. The engines and starters only come that way, it's 24 volt or pneumatic driven, no 12 volt choice at all.
So what are the advantages?
* All the wiring for the DC equipment is generally half the size.
* Inverting only requires half the DC amp input. (pretty substantial 150 amps 12 DC input to drive the microwave. 75 amps for the 24 volt.)
* Onboard equipment could be more specialized (a bonus for the manufacturer)
* Possibly better cold weather starts.
* Cooler running altenator for high amp loads.
* Need more or bigger batteries for substantial amp hrs.
So, can anybody add to this or have any ideas?
