Hi,
The reason I mentioned class A or C motorhome is because they generally share some common characteristics in their AC/DC system. I am comparing the options of 12 vs higher voltage system. In this post, I want to limit the discussion to the effect in generator.
Usually on class A or C, there are built in generators and by default house batteries are used to start the generator. That means the generator uses12V DC as its starting power, and usually the starting current can be pretty high for a brief period.
If the battery system is upgraded to higher voltage system, then the house batteries can no longer be used to start the generator. How should the starting power be provided to generator? I don't think any DC step down converter can handle that much current (or at lease not within a reasonable cost).
Thanks!
