Queensland solar and battery installation guide
Understand Energex connection rules, installer accreditation, electrical standards, available incentives and the decisions that shape a safe, effective home energy system.
Information reviewed 18 September 2026. Requirements and incentives can change.
Local network
Energex connections
New and modified grid-connected solar and battery systems generally require a network connection application.
Accreditation
Solar Accreditation Australia
SAA manages installer and designer accreditation under the Small-scale Renewable Energy Scheme.
Current support
Federal battery incentives
Eligible installations may receive support through STCs and the Cheaper Home Batteries Program.
Solar designed for Queensland homes
Queensland has exceptionally high rooftop solar adoption, but available sunshine alone does not determine the right system.
Understanding Energex solar and battery connections
Your installer will normally prepare and submit the connection application, then configure the system to match the accepted connection offer.
Dynamic connections
Energex can vary a site’s export limit according to network conditions. This can enable larger systems while helping the local network manage high daytime solar exports.
- Up to 10 kVA solar PV inverter plus 10 kVA battery inverter capacity may be available on single phase.
- A single hybrid inverter is generally limited to 10 kVA total inverter capacity.
- Fixed single-phase connections are generally limited to 10 kVA total inverter capacity.
- Final limits depend on equipment, network capacity and the Energex connection offer.
Battery connections
A new network application may be required before a battery is installed or an existing solar system is modified.
- The battery may be configured as export, non-export or dynamically controlled.
- Changing a non-export system to export later generally requires another application.
- Connecting a battery can require switchboard rewiring and backup-circuit design.
- Grid-connected battery systems must meet applicable inverter connection requirements.
Accredited, licensed and properly documented
Accreditation, electrical licensing, approved equipment and technical compliance are separate requirements. A reputable proposal should address all of them.
Solar Accreditation Australia
SAA is the current installer and designer accreditation scheme operator under the federal Small-scale Renewable Energy Scheme.
Clean Energy Council
The CEC no longer accredits individual installers. It continues to provide consumer guidance and administer approved-product programs.
Clean Energy Regulator
The CER administers the SRES. Eligible installations require accredited design and installation, electrical licensing and approved products.
Use current terminology
Individual installer accreditation transferred from the Clean Energy Council to Solar Accreditation Australia in 2024. “SAA-accredited installer” is the current description; “CEC-accredited installer” refers to the former scheme.
Standards that protect your home
A compliant installation must satisfy the standards, Queensland electrical safety requirements, network conditions and manufacturer instructions that apply to the project.
AS/NZS 3000
Wiring Rules
General safety and wiring requirements for electrical installations.
AS/NZS 5033
Solar PV arrays
Installation and safety requirements for photovoltaic arrays and DC systems.
AS/NZS 4777
Inverter connections
Requirements for grid-connected energy systems operating through inverters.
AS/NZS 5139
Battery systems
Safety requirements for battery energy storage systems and installation locations.
Projects may also need to comply with the Queensland Electricity Connection Manual, Energex embedded-generation standards, the accepted connection offer and current Queensland electrical safety legislation.
Current Queensland incentives and tariff considerations
Incentive values and electricity plans change. Confirm eligibility and current amounts when the system is quoted.
Solar STCs
Eligible small-scale solar systems may receive Small-scale Technology Certificates. These are commonly assigned to the retailer for an upfront reduction in the installed price.
Cheaper Home Batteries
The federal program supports eligible household battery installations through the STC framework. Incentives became tiered by usable battery capacity from 1 May 2026.
Feed-in tariffs
South East Queensland feed-in tariffs are offered by electricity retailers. Compare the full plan—including usage rates and supply charges—not only the headline export rate.
Queensland Battery Booster
This state rebate closed to new applications in 2024. It should not be advertised as a currently available Queensland incentive.
44-cent Solar Bonus Scheme
Adding panels, replacing an inverter or installing a battery may affect grandfathered eligibility. Confirm any proposed change with the distributor and retailer first.
South East Queensland and regional Queensland differ
The network distributor, retail market and feed-in tariff arrangements depend on where the property is located.
South East Queensland
The electricity distribution network is generally operated by Energex. Homeowners can choose between authorised electricity retailers and market feed-in tariffs.
Brisbane · Logan · Ipswich · Moreton Bay · Redlands · Gold Coast · Sunshine Coast
Regional Queensland
The distribution network is generally operated by Ergon Energy Network. Retail and regional feed-in tariff arrangements differ from South East Queensland.
Confirm the network, retailer and tariff for the property postcode.
Questions to ask before choosing a system
Clear answers help you compare proposals on system design, compliance and long-term value—not price alone.
Do I need Energex approval before installing solar?+
A new or modified grid-connected solar or battery system generally requires an Energex connection application. The installer or retailer normally submits it on the homeowner’s behalf before installation.
How much solar can I install on single-phase power?+
The permitted inverter capacity depends on the connection type, equipment and property. Energex currently offers dynamic connection options that may support up to 10 kVA of solar PV inverter capacity plus 10 kVA of battery inverter capacity on single phase. A single hybrid inverter is generally limited to 10 kVA total. Final approval depends on Energex’s current requirements and connection offer.
What is a dynamic solar connection?+
A dynamic connection allows Energex to vary how much electricity a system exports according to network conditions. It can enable a larger solar and battery system without allowing it to export at maximum capacity all the time.
Who accredits solar installers in Queensland?+
Solar Accreditation Australia manages installer and designer accreditation under the Small-scale Renewable Energy Scheme. People completing electrical work must also hold the Queensland electrical licences required for that work.
Is Clean Energy Council installer accreditation still current?+
No. Individual installer and designer accreditation transferred to Solar Accreditation Australia in 2024. The Clean Energy Council continues to provide consumer guidance and approved-product programs.
Is the Queensland Battery Booster rebate still available?+
No. Queensland’s Battery Booster closed to new applications in 2024. Eligible households may instead benefit from the federal Cheaper Home Batteries Program, subject to its current rules and eligible equipment requirements.
Can a home battery run my house during a blackout?+
Only batteries and system configurations designed for backup operation can supply power during an outage. Many systems protect selected essential circuits rather than the whole home. Battery output, storage capacity, inverter configuration and appliance starting loads all affect backup performance.
Can I add a battery to my existing solar system?+
Often, yes. The existing inverter, switchboard, meter, available battery location and network connection agreement must be reviewed first. A new Energex connection application may be required.
Will adding a battery affect my 44-cent feed-in tariff?+
It can. Customers on the grandfathered Queensland Solar Bonus Scheme should confirm the proposed design and operating restrictions with their distributor and retailer before adding panels, replacing an inverter or installing a battery.
