Six reasons Brisbane homeowners pick Powerwall 3
The Powerwall 3 isn't just an iteration of the PW2 — it's a complete redesign. Here's what actually changed and why it matters for a Queensland home.
11.5kW continuous
Runs a 4-bedroom Brisbane home including ducted aircon, induction cooktop and pool pump simultaneously. Powerwall 2 maxed at 5kW.
Integrated solar inverter
6 MPPT inputs accept up to 20kW DC of panels direct. Skip the separate inverter — fewer parts, fewer failure points.
Whole-home backup
Switches to backup mode in under 100ms — appliances and computers never notice the grid is down. Powers everything, not just essentials.
Stack up to 4 units
Start with one 13.5kWh unit. Add another later for 27kWh, up to 54kWh total. AC-couples to existing solar too.
Tesla One app
Real-time monitoring, storm watch, time-of-use optimisation and VPP enrolment — all from your phone.
10-year warranty
Unlimited cycles, 70% capacity retention guaranteed. The only major brand offering unlimited cycles.
Brisbane install pricing
Fixed prices include hardware, Tesla Gateway 3, install, commissioning, app setup and 10-year warranty registration. QLD Battery Booster rebate of up to $4,000 applied separately at quote.
