Finn's Tesla Batteries Review & Verdict

You want the best grid-connected home battery? Then get a Tesla Powerwall. They look great, they work great, and the app is the best-in-class. You’ll find you use the Tesla app not just to monitor your battery, but your solar and home energy consumption too – because it is so much better than the app that came with your solar inverter.
As you might expect from a Tesla product, the Powerwall is also very smart: it can charge and discharge to maximise your bill-savings in a way that is more sophisticated than any other battery I’ve tried.
The Tesla Powerwall also set the standard for blackout protection. It just works, and it does it properly – switching over in about 1 second and happily charging from your solar panels while the grid is down.
The Powerwall updates automatically over-the-air, and if there’s a problem, Tesla’s Australian support is excellent.
