How Much Does a Sigenergy Solar Battery Cost in Queensland?
The Sigenergy solar battery price in QLD starts from $7,821* after rebate for 16kWh of battery storage. 24kWh starts from $8,821*, and 48kWh from $16,121*, each a complete home energy storage system with a Sigen hybrid inverter included.
How much a Sigenergy battery costs depends on 3 inputs: module count, system size and the battery rebate on your install date. GREON checks every quote against the 2026 data below.

- WHAT'S INCLUDED
What's Included in Every GREON SigenStor Quote
Every GREON quote covers 4 parts: battery units, an inverter, cabling and installation with paperwork. You pay one price for a complete solar battery Sigenergy system, with each line itemised.
Battery Units
SigenStor BAT 8.0 modules of 8.06kWh each, sized to your night-time use, so you compare Sigenergy batteries line by line.
Hybrid Inverter
The Sigen energy controller converts DC from the roof to AC power for your home, suits single or three phase supply and replaces older inverters.
Cabling and Protection
Isolators and cabling between the stack, the inverter and your main switch. Switchboard upgrades sit on separate lines.
Installation and Paperwork
Labour by an Australian solar installer, testing, rebate paperwork and the Energex or Ergon connection.
GREON quotes residential installations across Queensland in one format, with storage in kWh and solar panels listed beside the battery.
- PRICE FACTORS
What Changes the Price of a Sigenergy Battery?
6 factors set every Sigenergy solar battery price in QLD: modules, inverter size, backup, switchboard, cable distance and phase. Each sits on its own line, so the Sigenergy battery price stays clear before the rebate comes off.
Modules
Each BAT 8.0 module adds 8.06kWh of storage, and the installed cost per kWh drops as the stack grows.
Controller Size
Sigen energy controllers act as a built-in hybrid inverter, from 5 to 12 kW single-phase and up to 30 kW for three-phase systems. MPPT inputs take DC from PV strings and send AC to the home.
Switchboard
Older boards need an upgrade, checked from a photo.
Roof and Cable
Double-storey homes and long cable runs add labour.
Backup
Whole-home backup adds a Gateway line.
Supply Type
Single-phase or three-phase supply sets the controller, battery and separate inverter needs. Three-phase homes suit pools and larger systems.

- THE REBATE
How Much Is the Federal Rebate on a Sigenergy Battery?
The federal Cheaper Home Batteries Program takes about $3,914 off a 16kWh Sigenergy solar battery installed in 2026. Every kWh up to 14 earns the full STC factor of 6.8, and GREON deducts the solar battery rebate before you pay.
Each small-scale technology certificate is worth about $38. Your rebate equals usable storage multiplied by the factor and the $38 value.

A 3 × BAT 8.0 SigenStor (24kWh) earns 136 credits, about $5,168.
Beat the 1 January 2027 Step Down
The factor drops from 6.8 to 5.7 on 1 January 2027, and the install date sets the rebate. A 16kWh system then earns 86 credits, about $3,268, a $646 drop.
QLD Rebates and Incentives
The state Battery Booster closed in May 2024, so the federal battery rebate is the only battery incentive in 2026. Rebate eligibility needs a CEC-listed Sigenergy SigenStor and an approved installer. GREON lodges every claim, and the pricing on your quote shows costs with the rebate applied.
See the full rules on our [solar battery rebate guide].
- SIZE OPTIONS
Sigenergy Battery Sizes: 16kWh, 24kWh and 32kWh
Most homes fit one of 3 Sigenergy home battery sizes: 16kWh for essentials, 24kWh for growing families and 32kWh for EV owners. The first 14kWh of every size earns the full rebate rate.
12kWh for Essentials
For 2 to 4 people with night-time aircon, lights and cooking.
- Stores 16kWh on 2 × BAT 8.0 modules
- Keeps reliable backup power running with a Gateway
- Expands later without new hardware
26kWh for Growing Families
For 4 to 6 people and larger homes with pools.
- Holds 24kWh of storage capacity on 3 × BAT 8.0
- Grows in a stackable, modular tower
- Delivers seamless blackout backup
35kWh for Maximum Savings
For homes with electric vehicles.
- Holds 32kWh of battery capacity on 4 × BAT 8.0
- Adds a 25kW DC charger for EV charging
- Uses integrated battery modules
Each size is the same Sigenergy SigenStor all-in-one energy system, so your energy needs set the choice. A 14 panel roof of about 6.6kW suits 16kWh, and 28 panels of about 13.2kW cover 32kWh. Compare the [Solar + Battery Packages] to match each size.
- GET SIZED RIGHT
How GREON Sizes the Right Sigenergy Battery for Your Home
GREON sizes every Sigenergy solar battery from 3 inputs: night-time use, solar production and backup needs, then recommends the smallest SigenStor stack that covers them.
01
Night-Time Use
Your last 2 bills show the loads you draw after dark, which sets the module count.
02
Solar Output
A 6.6kW rooftop solar system makes about 26 kWh a day. Larger solar systems reach 41 to 52 kWh of solar generation.
03
Backup Needs
Blackout cover adds a reserve for essential load during a grid fault.

- YOUR RETURN
How Much Can a Sigenergy Home Battery Save You Each Year?
A Sigenergy SigenStor saves about 30c for every unit of solar you use after dark instead of exporting it for single-digit cents. A home that shifts 12kWh a day saves about $1,314 a year, before virtual power plant income.
From 1 July 2026, the Solar Sharer Offer adds 3 free midday hours in SEQ for your SigenStor to store.
Pimpama Family With a 6.6kW Solar System
A family of 5 buys 12kWh after dark from the grid. A 16kWh solar battery covers that usage, a payback of about 6 years.
Tamborine Acreage Through Storm Season
After ex-Cyclone Alfred in March 2025, a 24kWh system with backup keeps the fridge, pump and Wi-Fi on.
Upper Coomera Couple Charging From Stored Solar
A 32kWh battery with a 25kW EV charger covers 60km of daily EV charging from solar panels.
- Illustrative figures based on 2026 tariffs. Every GREON battery is VPP-ready for QLD virtual power plants.
- STORM READY
Does a Sigenergy Home Battery Provide Backup During Outages?
Yes, with a Sigenergy Gateway. It moves the house to battery and solar power with 0ms load-side disruption, so lights, fridges and computers stay on, much like a UPS.
- The Gateway isolates the house from the network.
- The battery storage supplies your essential circuits.
- Solar panels recharge the battery by day.
Without that unit, the system shuts down in a grid fault, as AS/NZS 4777 requires. Each SigenStor also offers a 20ms backup mode for selected circuits.
Storm season runs October to March in SEQ. A 16kWh solar battery runs a fridge, lights, Wi-Fi and fans for about 2 days in an outage.
Tell GREON early, and the design includes seamless switching from day one.
- ADD TO YOUR SOLAR
Add a Sigenergy Battery to Your Current Solar System
Most Queensland houses keep their solar panels when they add a SigenStor. Its inverter takes panels directly or pairs with a current solar inverter through AC coupling.
Your Roof Stays Untouched
Rails and wiring stay in place, so your existing solar system keeps producing solar energy.
Old Inverter Replacement
An ageing string inverter swaps for the SigenStor inverter, so one unit runs roof and battery.
Any Phase Supply
Single-phase and three phase homes both connect, from 5 kW.
Solar and Battery Tracking
Track solar panel output and EV charging in the mySigen app, with smart AI control and monitoring.
EV Charger Installation
GREON fits EV chargers beside the SigenStor in one visit.
Compare each solar battery Sigenergy pairing on the [Solar + Battery Packages] page, or read the [Solar + Battery Installation Process].

- FAQS
Sigenergy Solar Battery Questions From Queensland Buyers
How much is a Sigenergy battery after the rebate in Queensland?
The Sigenergy solar battery price for 24kWh starts from $8,821* installed, after rebate, and 16kWh from $7,821*. The final Sigenergy battery cost depends on roof, switchboard and backup.
Are synergy solar batteries the same as Sigenergy?
Yes. The phrase is a common misspelling of Sigenergy, maker of the SigenStor home battery. Synergy is also a Western Australian energy retailer with no link to this energy storage system.
Is a Sigenergy battery eligible for the federal rebate?
Yes, when the modules sit on the Clean Energy Council listing and a qualified installer fits them. GREON checks eligibility and claims the STC rebate for you.
What happened with the Sigenergy recall?
The ACCC published a voluntary recall on 19 November 2025 for some 8, 10 and 12kW units with quick-connect plugs. Sigenergy replaced affected units free and extended their cover.
Is the SigenStor Neo worth waiting for?
Sigenergy unveiled the SigenStor Neo on 13 March 2026 with a built-in backup switch. Its Australian listing is pending, so GREON prices the current storage system and confirms Neo stock on request.
