Tesla Powerwall 3 (Australian version) explained

I've cherry picked the main features, pros and cons, of the new Tesla Powerwall 3. It won't make many of our fellow West Australians very happy, but I think for East Coast Australians this will be an option worthy of their shortlist.

In summary:
5kW and 10kW single phase solar inverters with 3 x MPPTs capable of connecting 20kW of panels
13.5kWh Lithium Iron Phosphate battery with backup Gateway for grid outages.
Can connect to 3 phase homes but only on one phase.
Differs from Powerwall 2 in that PW3 is a hybrid solar and battery product.
PW2 was battery only, no solar.

Western Australian rules will make it very difficult to sell this product widely.
5kW single phase solar inverter limit on both single phase and three phase, so we can never sell the 10kW TP3 model. Worse still, unlike Powerwall 2 which we could install in addition to the 5kW solar limit as it was a pure battery only inverter, no solar, we can't install Powerwall 3 like this because it can connect solar panels, even if none are actually connected.
