Solar Battery Cost Calculator & Price Guide
Use our solar battery calculator to estimate what a home battery could cost in Australia, whether you are comparing a solar and battery calculator result or checking a solar panel and battery calculator estimate. Based on current installer pricing, battery systems typically work out at about $900 to $1,350 per kWh in AUD, with a minimum installed job charge of $7,000.
Estimate solar battery installation cost
Indicative fully installed prices. State battery rebates (Vic, SA, ACT, Qld) not included — confirm current availability with your installer.

Solar Battery Price Breakdown
Typical job based on 10 kWh. Prices are supply-and-install midpoints — actual quotes will vary.
| Type | Cost per kWh | Typical 10 kWh job |
|---|---|---|
| Value (BYD, Alpha ESS, Sungrow SBR) | $900 | $9,000 |
| Mid (Sungrow SBR Pro, Huawei Luna, Enphase) | $1,100 | $11,000 |
| Premium (Tesla Powerwall 3, sonnen) | $1,350 | $13,500 |
What Affects Solar Battery Cost?
- Battery size in kWh: The biggest driver of price is the storage size you choose, because battery pricing is calculated per kWh. A larger system gives more usable storage but increases total upfront cost.
- Battery tier and brand: Value batteries such as BYD, Alpha ESS and Sungrow SBR are priced at $900/kWh, Mid options like Sungrow SBR Pro, Huawei Luna and Enphase are $1,100/kWh, and Premium systems such as Tesla Powerwall 3 and sonnen are $1,350/kWh. The tier you choose changes both the price per kWh and the included features.
- Minimum installed job charge: Even if the per-kWh maths comes out lower, the minimum installed price is $7,000 AUD. This means smaller battery systems may cost more than a simple per-kWh estimate suggests.
- Estimate range shown in the calculator: The displayed estimate range uses plus or minus 15% around the midpoint price. This gives a realistic guide for solar battery storage cost and home battery storage cost without pretending every installation is identical.
Solar Battery Cost - Frequently Asked Questions
The solar battery calculator estimates cost by multiplying your chosen battery size by the rate for the tier you select. Value pricing is $900/kWh, Mid is $1,100/kWh, and Premium is $1,350/kWh, with a minimum installed job charge of $7,000 AUD. The calculator then shows a range using ±15% around the midpoint.
For a typical 10 kWh example, a Value battery is estimated from $7,650 to $10,350 around a $9,000 midpoint. A Mid battery is estimated from $9,350 to $12,650 around an $11,000 midpoint, while a Premium battery is estimated from $11,475 to $15,525 around a $13,500 midpoint. These figures are in AUD.
A practical guide is to look at the per-kWh pricing: $900/kWh for Value, $1,100/kWh for Mid, and $1,350/kWh for Premium battery systems. For a common 10 kWh battery, that means midpoint pricing of $9,000, $11,000, or $13,500 AUD before applying the displayed ±15% range. Smaller systems can still come back at the $7,000 minimum installed price.
Yes, but it also applies the minimum installed charge of $7,000 AUD. If the per-kWh calculation falls below that amount, the estimate will still start from $7,000 rather than a lower raw figure. This is important when comparing smaller storage sizes.
The calculator groups battery options into Value, Mid, and Premium tiers. Value includes BYD, Alpha ESS and Sungrow SBR at $900/kWh, Mid includes Sungrow SBR Pro, Huawei Luna and Enphase at $1,100/kWh, and Premium includes Tesla Powerwall 3 and sonnen at $1,350/kWh. The displayed estimate range is then calculated at ±15% around those midpoint prices.
Premium home battery storage cost is based on $1,350 per kWh. For a 10 kWh system, that gives a midpoint of $13,500 AUD, with a displayed estimate range of $11,475 to $15,525. Premium options in this tier include Tesla Powerwall 3 and sonnen.
