The best thing to do with a totally disconnected house is go with solar/wind to charge control, to battery bank(s), to fuze, to inverter(s) to standard circuit breaker box. For more than 30 feet, the wire size for DC goes to thick while with an inverter, standard 3 (or 4) wire house wiring can be used. Hair dryers and irons use too much electricity, and only some washers will tolerate modified square wave electric of the less expensive inverters (like my Staber 2000). You will want to go with all LCD or CF lighting, LED TV, LED monitor, and energy star other appliances. Do some reading on solar installation, and do the worksheets for system sizing. Paying others to install costs big money, but with DIY you may need someone licensed to look at your work and sign it off before inspection. There isn’t much available with 12VDC appliances, some lights, car vacs, and other little, less powerful stuff, for cars. Some have built in inverters after the cigarette lighter plug. My hybrid even has a low power 110VAC outlet. Inverters come in European 220 VAC 50 Hz, or 110VAC 60 Hz.
