How much does the Sigenergy cost in 2026?
The Sigenergy typically costs $10,000–$12,500 fully installed in 2026 (16 kWh usable, inverter included). After the federal Cheaper Home Batteries rebate that's roughly $7,140, 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 | $10,000–$12,500 |
| Federal rebate now | −$4,110 (16 kWh usable) |
| Typical net price | $7,140 |
The federal battery factor is scheduled to step down to 5.7 STCs/kWh on 1 January 2027. Installed after that date, the same Sigenergy SigenStor would earn about $679 less in federal rebate, before any state top-up.
