One thing, you will not be able to run an a/c with enough BTU's to cool your van on batteries, even with solar. You are going to need a generator, and at least a 9,000 BTU a/c and then your only looking at 10 to 15 degrees cooling below outside temps. As for sizing a generator, double the BTU's of the a/c to get the gen-set size. So in this case you would need a 2,000 watt generator to start, and run the a/c.
Vans, do to all the glass, metal body, air holes, are the hardest type of RV to cool.
Check out the much larger Sprinter based E-Trek at roadtrek.com under models.
They are using an all electric configuration including heat, water heating, cooking, and air conditioning all running on batteries and solar.
Yes, and they are realistically only getting about 4 hours of a/c use, before having to fast idle the engine to use their upgraded engine generator, to recharge the 8 coach batteries. To use the a/c with out hook ups, you are going to have to use some kind of generator other wise the batteries will be drained in a very short time. Remember you only have half of the batteries amps to use, you do not want to discharge past 50 %.
8 batteries, engine generator, large inverter, etc are going to reduce the CCC's by about 800 lbs. and is expensive.
