The only problem about going off grid is that to keep your batteries alive for a good amount of time you can only really run them down to 50% depth of discharge for maximum life, assuming you run with the tried and true sealed lead acid style batteries, so think what you need than double it to get good life out of them.
Its probably cheaper to have a smaller battery system just to take over night loads and then a massive solar setup for during the day, as panels/inverters would be cheaper than battery bank.
Lithium Polymer batteries can withstand higher charging rates, and more discharges, but $$$!
