You should do some modelling of your options, but yes maximum panels is money better spent than batteries if you can get a good feed-in-tariff. Do’t forget you lose panel efficiency at all but optimal angles, and also be mindful that you need a lot of winter solar to fill two batteries, so your payback may be a lot longer than you think if your solar is too small for your batteries.

Sure, 30% pitched roof with good east, north (mainly) and west....if I use the best kw pannels I should be able to get just under 30kw as a total system size....I would hope this would easily put in up to 60kw per day in winter (house, batteries and feed in etc.).
Best I'll do is about 12 cents per kw in Melbourne.....

My all north facing 30kw system in Adelaide, albeit less than the 25 degree optimum pitch, produces 63kwh average per day during the worst two months, which are May and June.

Your weather isnt as good in melb so that will lose a small amount. 30 degrees is good, which will be better than mine, optimum in fact. West at 30 degrees you will lose 17%, and east 18%.
Microinvertors will give you a better result than a single invertor as well, as you wont get system-wide shutdown from panel issues. The enphase microinvertors come with a really good app that shows performance and issues on each panel.

The feed-in amount isnt as important as the difference between your consumption charge and feed-in tarif.
