Meet Tesla Powerwall Battery and solar inverter in one box, with room to add more later.
- Solar inverter built in
Powerwall 3 has its own solar inverter, so new panels connect straight to the battery. One box does both jobs.
- Already have solar? There's Powerwall 3AC
Powerwall 3AC is a battery-only version made for homes adding storage to an existing solar system.
Check whether your quote is a Powerwall 3 or a Powerwall 3AC. The 3AC puts out up to 5 kW.
- Enough power for most homes
Up to 11.04 kW of steady output starts heavy loads, and Tesla says one unit covers most homes' power needs.
Output depends on the power setting on your quote: 5, 10 or 11.04 kW.
- 10 years' cover, unlimited cycles
Ten-year warranty, with at least 70% capacity left at year ten and no cycle limit for solar and backup use.
Ask your installer to confirm they're Tesla-certified; the warranty requires it. Keep it online and registered, or Tesla may honour only four years.
Owners say blackouts barely register, and praise the app (SolarQuotes, Oct 2026).
The company behind it
Tesla is the US electric-car maker; its energy arm builds Powerwall home batteries and grid-scale storage.
Powerwall since 2015
Australia was among the first markets for Tesla's original Powerwall, announced in 2015.
Storage at scale
Tesla deployed 43.5 GWh of energy storage in the 12 months to September 2025.
Sydney warranty desk
Tesla's warranty lists an Alexandria, Sydney address and a 1800 number for Australian claims.

Is Tesla Powerwall right for your home? Fit and warranty checks
A good fit if…
- Single-phase homes buying solar and battery together — the integrated inverter is where the value sits
- Households who want maximum virtual-power-plant choice; Powerwall works with effectively every major Australian VPP
- Buyers who want one manufacturer accountable for the whole system rather than three
- People who want the longest local operating history behind the product on their wall
Consider the limitations
- You have a three-phase home and want whole-home backup — Powerwall 3 energises one phase, even with multiple units
- You want a large stack; cost per kWh is materially better elsewhere at bigger capacities
- You already have a recent hybrid inverter you do not want to strand
- You want fine-grained sizing — Powerwall comes in fixed blocks, not small increments
The Tesla Powerwall range
Powerwall 3 Expansion
Battery-only modules behind the main unit
Adds capacity without a second inverter. Cheaper per kWh than adding whole units.
Backup Gateway
Whole-home or partial
The hardware that isolates your home from the grid during an outage and decides what stays live.
Tesla Powerwall specifications and source documents
Powerwall 3 puts the battery and a solar inverter in a single unit, so a new solar-and-battery install needs one device on the wall instead of two. Battery-only expansion units sit behind it if you want more capacity without a second inverter. It has the broadest virtual-power-plant support of any battery sold in Australia and the longest local operating history. The catch is structural rather than technical: Powerwall 3 backs up a single phase, so three-phase homes wanting whole-home backup need to read the quote very carefully.
Tesla Powerwall questions, answered
- Does the Tesla Powerwall 3 work with a three-phase home?
- It can be installed on one, but backup is single-phase — Powerwall 3 energises one phase during an outage, even where several units are fitted. If whole-home backup across all three phases matters to you, ask the installer to show exactly which circuits stay live, and compare against batteries built around three-phase backup. This is the most common misunderstanding in Powerwall quotes.
- Is the Powerwall 3 eligible for the federal battery rebate?
- Yes. Powerwall 3 is on the Clean Energy Council approved battery list, which is the gate for the federal Cheaper Home Batteries Program. Note that the older Powerwall 2 has been withdrawn in Australia and is off the approved list, so it no longer qualifies — if a quote offers one, ask why.
- How many Powerwalls do I need?
- For most Australian households one unit covers the evening peak and overnight base load. A second becomes worthwhile if you have an EV, ducted air conditioning, or a genuine appetite for riding out long outages. Beyond that, the cost per kWh makes modular stacks hard to ignore — so if your target is a large system, price both approaches.
- Is a Powerwall still worth buying now that other brands outsell it?
- Losing the market-share crown is not the same as being a worse product. What Tesla still holds is the longest Australian operating history of any current battery and virtual-power-plant support no competitor matches. What it has lost is the price argument and, for three-phase homes, the backup argument. If you are single-phase and value proven longevity over cost per kWh, it remains a straightforward choice.
- Can I add a Powerwall to solar I already have?
- Yes, but how well it works depends on your existing setup. Powerwall 3’s value is largely in its integrated solar inverter, so retrofitting onto a healthy existing array means either re-terminating your panels into it or running the system in a configuration that leaves some of that value on the table. Ask the installer to explain which approach they are quoting and what happens to your current inverter.
- Will one Powerwall run my air conditioning?
- Usually yes for a split system, and it depends for ducted. Powerwall 3 has a strong continuous output rating, so the constraint is normally total energy across the evening rather than instantaneous draw. Ducted air conditioning running for hours on a hot night is what empties a single unit. If summer cooling is the main reason you are buying, ask the installer to model your actual usage rather than quoting a unit count.
- Can a Powerwall be installed outdoors in the Australian heat?
- Yes, it is rated for outdoor installation, and plenty of Australian Powerwalls live outside. What matters is orientation and shade: a unit on an unshaded western wall in a hot inland town works harder to stay cool than the same unit on a southern wall. It is also the most common source of fan-noise complaints, so think about proximity to bedrooms before you approve the mounting position.
