There are no household DC air conditioners available. The compressors require too much current at 12 or 24 Volts DC. and the cost of hook up wire alone would be prohibitive. All solar housing is based on a 12 or 24 volt Battery bank and 120 VAC converters. There are some small 12v appliances (coffee pot, slow cooker, etc.) available, but are expensive and terribly inefficient. It gets extremely expensive to power a house this way. Usually solar power is used where electricity is unavailable, and then just for basic needs. As an example, I have 4 batteries in my motor home and a 2000 watt converter which is about equivalent to one 120v 20amp circuit. That cost, at current prices would be roughly $3500. If you'd like, I can find a few more links for you to look at. That would save you a few hours of looking through a google search to find pertinent links. Getting older and still not down here.
