Anyone heard of a Combo AC/DC Air conditioner?

Suddenly from "Lithium batteries will give you all the power you might want" topic we landed "you will not have enough power"
12 or 24V AC are used more than some can imagine.
Obviously they are not for climate where you need 15k BTU running 24 hr a day,
but with 3-400W of solar and good battery bank, smaller unit will do 50% duty just fine.
