daserra,
Purely out of curiosity why would you want to go off grid when you are on grid as opposed to just minimising your on grid consumption to near zero ?

Partly the cost as we have large standing charges, secondly I like to provide for myself, perhaps my achilles heel but it's served me well up until now. If I can make a large investment and then not need to worry about energy expenses until my batteries need replacing I'll be happy.
We also use 27kwH/day at the moment as our hot water is electric also but this won't be for long. I have lived on 0.4kwH per day before, I just didn't like it much.
