Battery storage has gone from a fringe product to a mainstream conversation in the last two years. Feed-in tariffs have dropped, electricity prices have risen, and battery prices have fallen. But is it actually worth it for your home in SEQ?
Here’s the straight answer.
Who Benefits Most from Battery Storage
Battery storage works best when you have solar already and you’re exporting a significant portion of your generation to the grid. If your solar system generates 30kWh on a typical day and you only use 10kWh during daylight hours, you’re exporting 20kWh — and getting paid very little for it.
A battery captures that exported energy and makes it available in the evening when your solar is no longer generating. Instead of buying power from the grid at 30–35c/kWh, you’re using your own stored power.
You’ll benefit most from battery storage if:
- You’re already on solar and exporting heavily
- Your household is out during the day (commuters, workers)
- You have a high evening energy load — air con, cooking, entertainment
- Your feed-in tariff has dropped to under 10c/kWh
- You want backup power during outages
You’ll benefit less if:
- You’re home during the day and already consuming most of your solar
- Your quarterly bill is under $300
- You don’t have solar yet (add solar first, battery second)
The Federal Battery Rebate — Cheaper Home Batteries Program
There is now a significant federal rebate for home batteries. The Cheaper Home Batteries Program provides approximately 30% off the upfront cost of an eligible battery system, delivered the same way as the solar STC rebate — deducted from your quote automatically by the installer. You don’t apply separately.
Key eligibility points:
- Battery must be 5–100kWh in capacity (rebate only applies to the first 50kWh)
- Must be installed alongside a solar PV system at the same property — this includes off-grid solar systems, not just grid-connected homes
- Must be installed by an SAA accredited battery installer
- Battery must appear on the Clean Energy Council’s approved battery list
- Battery must have the capability to connect to a Virtual Power Plant (VPP) — connection is not mandatory, but the capability must be there
- No means testing — open to all Australians
Off-grid properties can claim this rebate — the requirement is that the battery is paired with solar at the same property. An off-grid solar-plus-battery system meets this requirement.
Important deadline: From 1 May 2026, the rebate structure changes and the discount for larger systems (above 14kWh) reduces significantly. If you’re considering a larger battery, acting before May 2026 locks in the current rebate level.
How Much Does a Battery System Cost in SEQ?
Battery pricing in 2026 has come down significantly, and with the federal Cheaper Home Batteries Program rebate (~30% off), the numbers are more compelling than ever. However, installed cost varies significantly depending on whether you want partial backup (essential circuits only) or full house backup (whole home backed up during an outage).
All prices below are after the Cheaper Home Batteries Program rebate and include full house backup (switchboard work, backup circuits). Quality brands, quality install.
| Capacity | Suitable for | Installed with full backup |
|---|---|---|
| 5–10kWh | Smaller home, essential backup circuits | $8,000–$13,000 |
| 10–15kWh | Average family home, full house backup | $12,000–$17,000 |
| 15–25kWh | Large home, high usage, EV charging | $17,000–$26,000 |
| 25–50kWh | Large property, multiple dwellings, commercial | Contact us — varies significantly by site |
Pre-rebate prices are approximately 30% higher. The rebate is deducted at point of sale — you pay the reduced price.
Note on the May 2026 rebate change: From 1 May 2026, the rebate drops ~20% for systems up to 14kWh, and reduces further on a tiered basis above that. If you’re considering a system larger than 14kWh, installing before May 2026 locks in a meaningfully better rebate.
Queensland does not currently have a state-level battery rebate to stack on top of the federal program.
Payback Period — The Honest Answer
With the federal rebate, battery storage payback has improved to typically 5–8 years in SEQ in 2026, depending on your usage profile, electricity tariff, and feed-in rate.
That’s still longer than solar alone (4–7 years), but the gap is closing. And payback isn’t the only consideration:
- Grid outage protection — particularly valuable for households with medical equipment, families with young children, or older residents who rely on air conditioning in Queensland summers
- Energy independence — less exposure to future electricity price rises
- EV charging — if you have or plan to get an EV, a battery lets you store solar energy and charge overnight

Which Batteries Do We Install?
We install specific models we trust for reliability, warranty support and performance in Queensland conditions — not just brands.
GoodWe ESA (grid-connected) The GoodWe ESA is an all-in-one system that integrates the solar inverter, battery and energy management into a single wall-mounted unit. Available in single-phase (3–10kW) and three-phase (5–29.9kW) versions with modular LFP battery capacity from 5kWh up to 48kWh per stack. IP66 rated so it can be installed indoors or outdoors. CEC approved and eligible for the Cheaper Home Batteries Program. Full house backup (63A) with no gateway needed. This is our preferred choice for most grid-connected homes.
BYD Battery-Box Premium HVM (grid-connected) The BYD HVM is a high-voltage modular battery system (8.3–22.1kWh) that stacks cleanly and pairs with a wide range of hybrid inverters. LFP chemistry, strong track record in Australian conditions and a well-established warranty and support network. Well suited to homes with higher storage needs.
BYD Battery-Box Premium LVS (off-grid) The LVS is a low-voltage system (4kWh per module, up to 24kWh per tower) specifically suited to off-grid applications. Its low-voltage architecture pairs well with off-grid inverter/chargers like the Selectronic SP Pro, its modular design allows capacity to be added over time, and it carries a robust IP rating for installations in sheds and rural properties. Our standard recommendation for off-grid battery storage.
SigEnergy SigenStor The SigenStor is one of the most technically advanced home energy systems available in Australia. It integrates solar inverter, battery storage, battery management, EMS and — optionally — a DC EV charger into a single unit, making it the only system that can charge your car directly from solar DC power without an AC conversion step. The built-in AI energy management system (backed by GPT-4 in the mySigen app) optimises self-consumption, VPP scheduling and fault detection in real time. Five-layer safety protection includes an internal fire extinguishing kit and aerogel-insulated cell pads. Scalable from 5kWh to 48kWh per stack. For households that want the most capable, integrated system on the market — including EV charging — the SigenStor is worth serious consideration.
Backup Power: What Can It Actually Run?
A common question — and the answer depends on your battery size and what you’re trying to run.
A 10kWh battery with backup capability can typically run:
- LED lighting throughout the house — all night
- Refrigerator and freezer — all night
- Phone charging, router, TV — no problem
- CPAP or other medical devices — yes
- Air conditioning (small split system) — 3–6 hours depending on conditions
- Electric oven or hot water — no, too power-hungry
For backup to work, your battery must be installed with a backup circuit. Not all installations include this — ask specifically when getting quotes.
Solar + Battery: The Right Order
If you don’t have solar yet, get solar first. The economics of battery storage depend on having excess solar generation to capture — and the federal Cheaper Home Batteries Program rebate also requires an existing solar system at the same property.
If you already have solar and are exporting heavily, now is a very good time to look at battery storage. Prices have dropped, the federal rebate is live, and systems are significantly better than those installed 3–5 years ago. If you’re considering a system larger than 14kWh, act before 1 May 2026 to lock in the current rebate level.
