I just want any battery system to be installed for 7kWh for under $5000 in Australia. I had hoped when the Powerwall 2 came out that you would be able to pick up the first version for that but alas. I really do think that the above 7kWh for $5k installed is the sweet spot. At that point its a no brainer purchase for anyone with over 3kw of solar panels. For me, with the stupidly high electricity prices in Australia (some of the highest in the world) at that point it would save me money in 3-5 years, and I am not the only one thinking like this. Among my friends and colleagues every single one has said at that price point they will pull the trigger and buy one. Even better if they are modular and can be upgraded again at a later date with additional storage.
