FoxESS Battery Prices in Australia 2026: Every Size, After the Rebate
A FoxESS CQ6-12 (12kWh) costs roughly $9,000 to $12,000 installed before rebates, or about $6,000 to $9,000 after the federal battery rebate, assuming a compatible FoxESS hybrid inverter is part of the job. Across the range, after-rebate cost lands around $540 to $750 per usable kWh, which puts FoxESS among the more affordable LFP options in Australia. Because it is a battery-only product, the biggest variable in any quote is whether you already have a compatible FoxESS hybrid inverter.
This page breaks down what each FoxESS size costs, the component split, and what pushes your own quote up or down. For the full product verdict, see our FoxESS CQ6-12 review.
FoxESS battery price by size (2026)
FoxESS sells two residential lines in Australia: the newer CQ6 (100% depth of discharge) and the modular EQ5000 (90% DoD, expandable from about 9.8 to 29.5kWh nominal). The figures below are indicative installed prices built from installer-network averages and the current rebate rate, assuming a compatible FoxESS hybrid inverter is included. They are a starting point, not a quote.
| Model | Usable capacity | Installed (before rebate) | Federal rebate | After rebate |
|---|---|---|---|---|
| EQ5000 (9.8kWh, L2) | ~8.9 kWh | $8,000–$10,000 | ~$2,225 | ~$5,775–$7,775 |
| CQ6-12 | ~12 kWh | $9,000–$12,000 | ~$3,000 | ~$6,000–$9,000 |
| EQ5000 (14.8kWh, L3) | ~13.3 kWh | $10,500–$14,000 | ~$3,325 | ~$7,175–$10,675 |
| EQ5000 (19.7kWh, L4) | ~17.7 kWh | $13,500–$17,000 | ~$4,055 | ~$9,445–$12,945 |
| EQ5000 (24.6kWh, L5) | ~22.1 kWh | $16,000–$20,000 | ~$4,715 | ~$11,285–$15,285 |
The rebate is calculated on usable capacity, so the EQ5000's 90% depth of discharge means a little less rebate per nominal kWh than a 100% DoD battery. The rebate also tapers above 14kWh of usable capacity (more below). See full specs on the CQ6-12 product page and the EQ5000 14kWh product page.
What makes up a FoxESS price
FoxESS is a battery, not an all-in-one system, so an honest quote separates the battery from the inverter it needs. Indicative supply-only prices:
| Component | Indicative price (supply) |
|---|---|
| FoxESS EQ5000 battery (14kWh) | ~$6,500 |
| FoxESS CQ6-12 battery | ~$7,000 |
| Compatible FoxESS hybrid inverter (if not installed) | $2,000–$3,500 |
| Installation (labour, electrical) | $2,000–$4,000 |
The inverter line is the one to watch. If you already run a FoxESS hybrid inverter, you skip that cost and the battery is a clean add-on. If you are on another brand of inverter, a FoxESS battery is not a retrofit option, you would change the inverter, so a broadly-compatible battery like the BYD Battery-Box often makes more sense in that case.
What changes your FoxESS price
- The inverter question. FoxESS batteries are DC-coupled and need a FoxESS hybrid inverter. Already have one, and you save $2,000 to $3,500. If not, that inverter is the largest single line in the quote.
- EQ5000 vs CQ6. The EQ5000 is cheaper per nominal kWh with a wider temperature range; the newer CQ6 adds 100% depth of discharge and a longer warranty at a slightly higher price.
- System size. The modular EQ5000 scales from about 9.8 to 29.5kWh nominal, but the rebate earns less per kWh above 14kWh usable, so match capacity to your overnight use.
- Retrofit vs new solar. Adding a FoxESS battery to an existing FoxESS hybrid inverter is a clean job; a home on another inverter brand needs the inverter changed too.
- Location and network. Labour rates and your distributor's export and backup rules shift both price and what the system is allowed to do.
The federal rebate on a FoxESS battery
The federal Cheaper Home Batteries Program discounts the installed price at the point of sale. As of 2026 it is worth about $250 per usable kWh on the first 14kWh of capacity, tapering above that (roughly $150/kWh from 14 to 28kWh, and $38/kWh from 28 to 50kWh), after the rate stepped down on 1 May 2026. On the 12kWh CQ6-12 that is about $3,000 off; on the 14.8kWh EQ5000, about $3,325. You can check what your state stacks on top with our rebate checker.
How FoxESS compares on price
On post-rebate cost per usable kWh, FoxESS is one of the more affordable LFP options from an established inverter maker, sitting close to the Sungrow SBR and BYD Battery-Box and well below the Tesla Powerwall 3. What you trade is brand recognition and VPP breadth, which are narrower than the market leaders. For the full field, see our solar battery cost guide and the best home battery guide.
How to get an accurate FoxESS quote
Because the inverter question drives so much of the cost, the only way to a real number is an itemised quote from an accredited installer. Ask for the battery, the FoxESS hybrid inverter (or confirmation your existing one is compatible) and installation as separate lines, and confirm whether the quote is for the EQ5000 or the newer CQ6.
