Low voltage Air Conditioning [RE-wrenches]

[Larry Crutcher, Starlight Solar]

Wrenches,

I did not get a response to my post from last week. I know most of you do not work with battery based systems but is there anyone here that can offer some experiential advice about low voltage air conditioning? 

Thanks again,
Larry Crutcher

  Does anyone have experience with DC air conditioning equipment? I have a 
  customer with a semi truck and wants a roof air for the sleeper.  Many 
  truck stops now forbid engine idling for more than 5 minutes so they can 
  not use the cab air. 

  A small diesel generator is one solution but the trucker is not sure if 
  some truck stops may forbid that as well. Since the truck engine is only 
  off for 10 hours or so, it looks like 18kWhr of battery @ 50% DOD  will 
  operate the A/C load until the engine starts again. 

  Some customers in Mexico are running mini-splits successfully but I 
  don't want to add the complexity of an inverter if there is a low 
  voltage DC solution.
