Bojan, I suggest that before you investigate off grid options, you do some sums on the necessary storage.
You'll find that Fridges, although only consuming small amounts of power run at high duty cycle, so for example a 125 watt load running 80% of the time will need a fair amount of storage just to run when your solar isn't producing power.
You might also want to factor in battery costs, at high depths of discharge batteries have a relatively short lifespan, so sizing of your battery bank will be a factor that will need to be balanced against your anticipated discharge, life expectancy and available budget.
I have self sufficiency with power at my shack on only a couple of 80 watt panels, but I run LPG hot water and a gas fridge and heater, once they're out of the equation power needs are miniscule.
