How much does the Fox ESS cost in 2026?
The Fox ESS typically costs $9,500–$11,000 fully installed in 2026 (10 kWh usable, plus a hybrid inverter if your system isn't battery-ready). After the federal Cheaper Home Batteries rebate that's roughly $7,537, and lower again with a NSW or WA state rebate. Compare it in our battery price guide and best home batteries list.
Price after the federal rebate
| Installed price | $9,500–$11,000 |
| Federal rebate now | −$2,713 (10 kWh usable) |
| Typical net price | $7,537 |
The federal battery factor is scheduled to step down to 5.7 STCs/kWh on 1 January 2027. Installed after that date, the same Fox ESS EQ4800 (~10 kWh) would earn about $439 less in federal rebate, before any state top-up. Check the full solar battery price guide for how every capacity compares, and how the Cheaper Home Batteries rebate is calculated state by state.

- Wide capacity range, up to 41.9 kWh in a single stack
- VPP-eligible through Origin Loop VPP
Where Fox ESS could be better
- Needs a separate Fox ESS hybrid inverter, it has no built-in inverter
- Backup power needs a dedicated EPS circuit set up at install, it isn't automatic whole-home backup
- Shorter Australian track record than Tesla, BYD or Sungrow
Who Fox ESS suits
Installs where a hybrid inverter is already planned and whole-home blackout backup isn't the priority.
