.....cut.....

Thoughts?

Thank you in advance.

For clarity, an air conditioner won’t run for 48 hours on 800 Amp-hours of 12.8 VDC batteries. When running steady on a hot day, I’d expect 6~8 hours at best before you would need to recharge. If taking 4 hours of fast idling with 200-Amp alternator, you would end up running diesel van engine too much of the time.

I personally support the conceptual design of what you are considering, but it has to be accomplished in a much more efficient manner from the start to make it viable if sustain air conditioning is planned.

If I were you, I would not eliminate the diesel generator in order to save a little weight unless air conditioning will be limited to short periods or overnight only. Just my 2 cents.
