Home Battery Prices in Australia

Home battery prices vary significantly depending on usable capacity, inverter size, installation complexity and available rebates.

Use the table below as a practical guide to typical installed pricing in Australia — the same anchors our evaluator uses when it recommends a specific system for your household.

Typical home battery prices by size

Battery sizeBest suited forTypical installed priceAfter federal rebate
10 kWhSmall household or couple, low evening usage$5,800 – $8,500$3,800 – $6,500
20 kWhAverage solar household, one A/C zone, no EV yet$7,600 – $12,000$3,600 – $8,000
30 kWhLarger household, whole-of-day A/C, one EV or pool pump$9,800 – $15,500$4,200 – $10,000
40 kWhHigh usage, EV charging at home, future-proofing to 2030$13,000 – $18,500$7,000 – $12,500

Prices are indicative installed totals (single-phase, no new solar) using June 2026 Australian dealer anchors — battery + matched hybrid inverter + install + CEC-accredited installer margin. Ranges span from cheapest LFP brands (Pytes, SOFAR) at the low end to premium brands (Sungrow SBR, Sigenergy) at the high end. Tesla Powerwall 3 and Sonnen sit above these ranges — see below.

Why the price range is so wide at each size

The same "20 kWh battery" can cost anywhere from ~$3,600 to ~$20,000 after rebate depending on the brand. The choice is not arbitrary — different brands optimise for different things:

  • Value LFP brands (Pytes, SOFAR, Growatt, HYXi) — cheapest per usable kWh, smaller AU installer footprint, longer RMA turnaround if a module needs replacement. Payback period 4–6 years for most households.
  • Mid-premium all-in-one (AlphaESS SMILE, FoxESS CQ, GoodWe Lynx) — one-piece design, wider AU dealer network, decent VPP compatibility. Payback 6–8 years.
  • Premium AU-supported (Sungrow SBR/SBH, Sigenergy SigenStor) — most-installed and best-supported in Australia, strongest VPP earnings, sleek modular design. Payback 8–10 years, offset by higher resale confidence.
  • Premium fixed-format (Tesla Powerwall 3, Sonnen Batterie) — 13.5 kWh fixed capacity per unit, longest brand recognition, highest sticker price. Rarely the shortest payback, often the customer’s emotional first choice.

How the federal CBRS rebate works

The Cheaper Home Batteries Scheme (CBRS) launched July 2025 and pays roughly $200 per usable kWh for the first 28 kWh of installed capacity, then approximately $38 per usable kWh above that. It is delivered through Small-scale Technology Certificates (STCs) that your CEC-accredited installer trades on your behalf — so the rebate appears as an up-front discount on your invoice, not a post-install refund you have to chase.

Battery sizeCBRS federal rebate
10 kWh~$2,000
20 kWh~$4,000
30 kWh~$5,600
40 kWh~$6,000

Some states stack additional incentives on top of CBRS. NSW residents who enrol in a Virtual Power Plant (VPP) can access the PDRS incentive; Victorian households can access the Solar Homes interest-free battery loan; Queensland and SA have periodic programs. Our personalised evaluator checks your state and postcode automatically and includes any applicable state rebate in the final out-of-pocket price.

Common extras that add to the base price

  • Whole-home backup wiring — from $395 (essential circuits only) up to $880 (whole-house automatic transfer switch). Solar-only inverters cannot back up anything during a blackout; only hybrid systems with a battery + backup gateway can.
  • Long cable run from switchboard — from $130 (5-10 m) to $705 (over 20 m). If your switchboard is on the opposite side of the house from the proposed battery mount wall, this can be a real line item.
  • Three-phase inverter premium — around $500 to $1,650 extra over single-phase if your home is on three-phase supply and you want a matched three-phase hybrid inverter (versus fitting a single-phase inverter to one phase, which is compliant but caps output).
  • Switchboard upgrade — $800 to $1,500 for very old ceramic-fuse or unsafe switchboards that fail the pre-install audit. Most homes built in the last 20 years do not need this.
  • Regional / remote install travel — $400 to $1,600 extra depending on distance from the CBD. Metro postcodes have no travel surcharge.

Frequently asked questions

How much does a home battery cost in Australia in 2026?+
For a typical single-phase household, installed home battery prices in Australia range from roughly $5,800 for a 10 kWh system to around $18,500 for a 40 kWh system before rebates. After the federal Cheaper Home Batteries Scheme (CBRS) rebate is applied, out-of-pocket costs drop to about $3,600 – $12,500 depending on size and brand. Mid-market LFP brands like Pytes, SOFAR, AlphaESS and GoodWe sit at the lower end of each range; premium brands like Tesla, Sungrow SBR and Sigenergy sit at the higher end.
What is the CBRS federal battery rebate worth?+
The Cheaper Home Batteries Scheme (CBRS) launched July 2025 and pays roughly $200 per usable kWh for the first 28 kWh of installed capacity, then approximately $38 per usable kWh above that. A 20 kWh battery therefore receives about $4,000 in rebate; a 30 kWh battery about $5,600; a 40 kWh battery about $6,050. The rebate is delivered through Small-scale Technology Certificates (STCs) and is normally applied by your installer as an up-front discount rather than a post-install refund.
Does the battery price include the inverter and installation?+
Yes — the ranges above are complete installed prices. They include the battery hardware, the matched hybrid inverter (a 6 kW single-phase inverter runs about $1,000 – $1,500; a 10 kW three-phase inverter about $2,100 – $2,700), the switchboard work, cabling, labour, compliance testing and the CEC-accredited installer margin. They do not include upgrades to a very old switchboard or a three-phase electrical upgrade if your home is currently single-phase, which are quoted case by case.
Why is a 20 kWh battery sometimes cheaper than a 10 kWh?+
The federal CBRS rebate scales with capacity, so a larger battery attracts more rebate. Combined with the fact that many brands price 10 kWh as a special "small home" SKU with limited volume, the net effect is that a 20 kWh Pytes or SOFAR system can land at similar or lower net cost than the same brand's 10 kWh. This is why our evaluator often recommends 15 – 20 kWh as the practical sweet spot rather than a strict 10 kWh entry.
What extra costs might apply on top of the numbers above?+
Three common site-specific extras: (1) whole-home backup wiring — around $400 to $900 extra depending on which circuits you back up; (2) long cable runs from switchboard to battery — around $130 to $700 extra depending on distance; (3) three-phase premium if you insist on three-phase inverter over single — around $500 to $1,650 extra for the inverter alone. Our evaluator quotes these transparently on your personalised report; use it to see the exact number for your address.
Should I wait for battery prices to drop further?+
Prices have already dropped substantially — the federal CBRS rebate delivered a step-change in mid-2025, and mid-market LFP brands now sit at levels that will not fall much further. For a household exporting more than 10 kWh per day of surplus solar, or paying more than $700 per quarter on electricity, the payback period is now 4 to 7 years, meaning waiting has an ongoing opportunity cost. That said, if your bill is under $400 per quarter and you have no existing solar, the payback maths still does not work — a battery is not right for every home.
