Your inverter consumes power just like any other appliance until it locks onto the 50hz frequency and can produce a higher voltage than the power coming in from the street. Grid feeding can only occur if the inverter voltage exceeds the grid voltage.
Whithin about 2 cycles per second your inverter will stay powered up if your panels are producing power...just that the inverter will stop grid feeding on it's output circuits.
(it will wait until the grid comes back up)

the average usable amount of sunlight to fall on the mid section of Australia is around 6 hours.....thereby any system that is facing north, unshaded and angled correctly will receive that amount
thereby a 5 kilowatt system averaging 6 hours per day will produce 30 kilowatts on average per day

The standard multiplier is 4.
5kw system is good for 20kw a day average, in most states with exceptions.
You will not get 30kw average all year round in any location in australia per day.
But you might average 365*20kw per year.
