Alex, I know the feeling, running idependant of the grid is a buzz, if a little expensive. I have 2Kw on the shack on a 24 V system, supplies all our power needs.
Our array is oversized, i.e. the capacity of the array is larger than the regulator will handle at 24V. That gives us better performance on cloudy days and on either side of the daily peak.
Most decent MPPT regulators will allow oversizing. We've just gone electric on the fridge, having used a Consul gas fridge since 91.
The new LG fridge freezer (340 Litres) uses under 30 amp hours a day ( around .5kwh) , not much more than my 12 V bushman which uses about the same but only has 50 litres capacity.
