My main train of thought is that for most of the year we get maybe 6-8 hours of daylight here, so solar alone will not produce enough unless you have a LARGE array and LARGE battery bank, ex: a battery bank you can charge fully in the summer months, then have enough capacity for the whole year, and simply trickle charge it a tad in the day which would simply slow down the overall discharge rate, but never fully charge it. The days are simply too short and nights are too long. Sun is down by 5pm and comes back up around 8am.
But yeah it sounds like wind is not really viable at small scale so I'll forget that. I think my dream of going off grid simply won't work where I am as I would need a bigger property for an alternate source to top up batteries half way through the night. So I'll probably concentrate on doing a small setup that will selectively power certain loads but not the whole house. I'm thinking I would just have various outlets throughout the house that go to a separate electrical panel that is powered by the inverter. Could plug all the phantom and occasional use loads in it. TV, lights, that kind of stuff. Maybe a few computers. Would also act as a backup source of power so if power goes out I still have basic power.
