How much does a solar battery cost in Brisbane?

Compare current installed starting prices below. This is the price and inclusions guide; use the Brisbane home battery systems page when your main question is capacity or configuration.

Brisbane & Queensland · current standard installed offers

Three installed price bands to compare.

Compact retrofit

20.72 kWh

FoxESS EP11 battery system for homes looking to shift a defined share of daytime solar into the evening.

From $4,999 installed · incl. GST, after rebate

Estimate my price

Family capacity

27.96–31.08 kWh

Two capacity paths around the same starting price, selected around system architecture and the home’s actual usage.

From $6,999 installed · incl. GST, after rebate

Estimate my price

High capacity

41.44–41.76 kWh

EP11 from $8,499 or CQ7-L6 from $8,999 for larger evening loads and more demanding system designs.

From $8,499 installed · incl. GST, after rebate

Estimate my price

Ordinary three-phase systems add $500. CQ7 and 15kW inverter options use a different surcharge. Prices include GST and standard installation after the federal battery rebate; backup, equipment changes and site work are confirmed in writing. Prices reviewed 3 August 2026 and may change when the offer or rebate settings change. The Australian Government’s Cheaper Home Batteries Program provides around a 30% discount on eligible small-scale batteries connected to new or existing rooftop solar; the exact applied amount is confirmed in the written proposal.

Which range might fit?

What each installed price band is designed to cover.

20.72kWh · compact retrofit

Often considered when existing solar is sound and the main goal is shifting a defined share of daytime generation into the evening. The inverter and current PV system still need to be checked.

27.96–31.08kWh · family capacity

Often considered by family homes with larger evening loads, air-conditioning or more solar to store. The right capacity depends on usage—not just the number of bedrooms.

41.44–41.76kWh · high capacity

Often considered for larger loads, EV charging or three-phase system designs. More stored energy does not automatically mean whole-home blackout backup.

What changes the quote

Six property inputs matter more than a generic package name.

Capacity and power

Stored energy, charge and discharge power, inverter output and backup output are related—but they are not the same specification.

Single or three-phase

The supply, existing DER and intended inverter architecture affect equipment and grid design. CQ7 and 15kW inverter options have their own surcharge path.

Existing solar

Keeping the current inverter, replacing it or changing the PV arrangement creates different equipment and labour scopes.

Switchboard

Protection, space, metering, backup separation and any required rectification must be assessed at the actual property.

Battery location

Cable distance, access, wall or floor conditions and current installation requirements can change the practical scope.

Blackout backup

Essential-circuit and wider backup designs require different switching, circuit work and load checks. Backup should be explicit in the proposal.

Turn the range into a written Brisbane quote.

Send your suburb, a recent bill, the existing inverter model and what you want to keep running in a blackout. We’ll identify any remaining site evidence needed for a firm proposal.

Cost questions

Read the inclusions, not just the number.

How much does a solar battery cost in Brisbane?

Our current standard installed ranges start at $4,999 for a 20.72kWh path, $6,999 for 27.96–31.08kWh paths and $8,499 for 41.44–41.76kWh paths, after the applicable rebate. These are starting points, not a fixed price for every property.

Are these Brisbane solar battery prices installed?

Yes. The published starting prices include GST and standard installation after the applicable federal battery rebate. Backup, switchboard rectification, long cable routes, equipment changes and other non-standard site work are confirmed separately in the written proposal.

Does the federal battery discount apply to existing solar?

Eligible small-scale battery systems connected to new or existing rooftop solar may receive support through the Australian Government’s Cheaper Home Batteries Program. The discount is generally around 30%, but the applied amount depends on usable capacity, STC settings, certificate values and the installation date.

Why can two Brisbane homes receive different quotes for the same battery?

Phase, inverter choice, switchboard work, cable route, backup circuits, installation location, existing-solar changes and grid requirements can all change the labour and equipment needed.

Does a larger kWh number mean more blackout backup power?

No. kWh is stored energy; kW is power. Blackout performance also depends on inverter EPS output, battery discharge limits, state of charge, switching equipment and the loads connected to the backup circuits.

Can you confirm a fixed price from a power bill alone?

A bill helps size the opportunity, but a firm scope also needs the suburb, phase, existing equipment, switchboard and battery location. Unknown site work should be identified before the final proposal rather than added as a surprise later.
