Tesla Powerwall
Powerwall is a strong product with a loyal following. It is also not automatically the right one for your house, and we will say so if it is not.
Households comparing one specific battery against the alternatives we install.
kW
Everything at once is about 5.45 kW, over the battery’s output. The backup circuits on their own sit well inside it.
kWh
about 19 hours
about 3.5 hours
Worked example on a 13.5kWh usable battery with 20% held in reserve. Losses, weather and your inverter’s limits change the real runtime, and your quote models it on your own usage.
You choose the backup circuits with us at design time, before anything is installed. This is a typical choice, not a fixed list.
What it costs
Your roof, your switchboard, your access and the size you actually need all move the number, so we price it properly rather than publish a figure we would have to revise. You get a fixed, itemised quote with every incentive already deducted.
What may apply to this
Federal · both states
Requires eligible solar installed or installed at the same time, and the battery must be on the approved list.
No amounts, on purpose: they change, sometimes mid-year. We confirm your actual entitlement in writing and show it as a deducted line on your quote.
Powerwall's reputation rests on two things: the backup is excellent, and the software is the most polished in the category. If keeping the house running through an outage matters to you, it is a serious contender.
It is not the cheapest kilowatt hour of storage you can buy, and for a household that just wants to shift daytime solar into the evening, something less expensive often does the same job. We will model both against your usage and show you the difference rather than steering you to whichever we would prefer to sell.

Honest comparison
We install both. The right answer depends on whether you are buying backup or buying cheaper evenings, and those are different purchases.
Premium storage with the strongest backup capability and the most refined app in the category.
Strong value storage that does the core job of shifting daytime solar into the evening, for less per kilowatt hour.
If riding out a blackout matters to you, Powerwall earns its premium. If your goal is simply to stop buying power at 6pm, a value battery usually reaches payback sooner. We model both on your consumption and show you the difference in writing.
Whether a battery can be retrofitted at all depends on your existing inverter. If it is not battery-ready, the choice becomes a hybrid upgrade or an AC-coupled battery, and that changes the maths. We check first.
What you get
We will show you Powerwall against the alternatives on your own numbers. Sometimes it wins, sometimes it does not.
Which circuits stay live in an outage is a decision made at design time. We plan it with you rather than defaulting.
The federal battery rebate is deducted from your quote and the paperwork is ours.
Most systems can be retrofitted. Where yours cannot, we will price the alternatives honestly.
Battery installation is regulated work with specific standards for placement and protection. Every install meets them.
Configured and demonstrated before we leave, so you can see charge, discharge and grid draw in real time.

Get a Free QuoteFor households that want reliable blackout backup and polished software, often yes. For households that only want to shift daytime solar into the evening, a less expensive battery frequently does the same job. We model both on your usage before you decide.
It is capable of whole-home backup, but whether yours will depends on your loads and how the switchboard is configured. Large loads like ducted air conditioning may need to be excluded. We work this out at design stage.
Usually yes. It depends on your existing inverter and switchboard. We check both before quoting and tell you if anything else needs to change.
The federal battery rebate applies to eligible installations, and Victorian programs may apply on top depending on your circumstances. We confirm your position in writing before you commit.
Typically a day for the battery itself. If the switchboard needs work or backup circuits are being reconfigured, allow longer. We give you the exact scope in the proposal.
Without storage, most households export the bulk of what they generate at a low feed-in rate, then buy power back at peak prices after dark. A battery closes that gap.
