are you using powerwall or powerwall 2 numbers, there's a difference.
besides, you should be accounting for your individual situation. is electricity especially cheap where you live? is it especially expensive? renewable? does it adjust easily to load or does the grid have a blowout when demand changes?
if you do it right it should at best save you money, at worst give you a good amount of redundancy from the grid and make your electricity cheaper.
if you're the type that likes laughing at people just wait until the power goes out again (i guarantee you this SA power bullshit will spread east to victoria and NSW) and start playing music.

Honestly It'd be cheaper if I just bought a couple batteries and wired up a converter from the solar panels.

Or have a gas powered generator.
