What does a home battery cost in Australia in 2026?
The short answer: a 10kWh battery system fully installed costs $7,000–$9,500 after the federal Cheaper Home Batteries Program rebate (roughly 30% off). Before the rebate, expect $10,000–$14,000 for a 10kWh system depending on brand and installer.
The Cheaper Home Batteries Program — funded to 2030 — provides a point-of-sale discount applied directly by your installer. You never have to claim it yourself.

Does adding solar change the cost?
Most Australians add a battery to an existing solar system. If you're starting fresh, a combined solar + battery package typically costs:

|---|---|---|
| Solar only | 6.6kW panels | $4,500–$7,000 |
| Solar + battery (mid-range) | 6.6kW + 10kWh | $14,000–$19,000 |
| Solar + battery (popular package) ★ | 10kW + 10kWh | $17,000–$24,000 |
| Solar + battery (premium) | 13.3kW + 13.5kWh | $22,000–$30,000 |
