I found this
All searches came up with sites that are by the same company. (really annoying light gray font on white page, hard for these old eyes to read, which may be their goal to keep you from reading the whole thing closely)
At $2000 for 12,000 BTU ($1725 from a site that direct link that reads like it is from same people) I could find no mention of any power consumption figures other than you need to supply from a battery bank with some way to charge said batterys. If you are solar to charge batteries the same lack of sun to charge batteries would also make the AC less efficient making it draw more from the battery bank.
