Tesla Powerwall 3

Existing solar can often stay, subject to the connection design.

Powerwall 3 can work with an existing AC-coupled solar inverter or with panels connected directly to its integrated solar inverter. We check the current inverter, array and supply before deciding what stays.

Powerwall 3 is a single-phase unit. On a three-phase property, the design must account for the loads on each phase; one unit does not automatically provide three-phase backup.

Choose usable storage and backup circuits together.

Each Powerwall 3 has 13.5 kWh of usable storage. Compatible Expansion units add storage, rather than another solar inverter. The number of units, space and connection requirements are confirmed for your installation.

Backup uses separate Gateway equipment and the circuits agreed in your design. Battery charge, running demand and appliance starting loads affect what can operate together. Tell us about any future EV charging so its demand is considered alongside storage.

Tesla’s 10 years manufacturer warranty is separate from PSW cover.

Tesla's AU/NZ warranty Rev1.17, effective 3 September 2026, covers Powerwall 3, 3P and Expansion. It gives ten years and 70% capacity retention. Unlimited cycles apply only to the listed self-consumption, time-based control and backup uses; other applications have a 37.8 MWh throughput limit. Registration, internet connection and operating conditions apply. Australian availability and the quoted configuration remain separate checks.

PSW’s installation and service cover for the battery system is 10 years. For equipment supplied and installed by PSW, from installation completion, only where your signed installation agreement includes this commitment. Your written quote confirms whether it does. Existing longer promises and Australian Consumer Law rights remain unchanged. Manufacturer warranties apply separately on their own terms.

PSW Life Support gives you a local team to contact after handover. Keep your equipment and installation records. The Australian manufacturer warranty is linked under Full specifications.

The table describes the Powerwall product; the Australian manufacturer documents give the complete ratings, operating limits and installation requirements. Your selected system, Gateway and any Expansion units are confirmed together.

• Battery, mounting and enclosure
• Hybrid or retrofit inverter integration
• Backup circuit configuration
• WA battery rebate paperwork
• Monitoring app setup before we leave

Your written quote confirms the equipment, site conditions, backup scope and applicable rebates. Extra site work is itemised. Solar panels are separate from the Powerwall guide; an Expansion-only request has its own scope.

Federal support and the WA scheme have separate conditions. Equipment, installation date and participation requirements affect eligibility; applicable deductions are shown on separate quote lines.

Tell us about a cold installation location. Tesla’s operating and temperature conditions inform the design; the heat-mode guide explains the detail.
