Use the total installed battery quote before any rebate or federal discount is applied.
Battery Rebate Calculator
Solar battery rebate calculator for Australia
Short answer
Use the main calculator to test the practical effect of a battery discount: enter your battery quote, estimate the rebate or discount shown by the installer, then compare the net cost against expected annual bill savings. Treat the result as planning only until an installer confirms eligibility and the final line items.
How to estimate rebate impact
Enter the discount or rebate estimate as a separate number so you can see the net cost.
Compare net cost against annual savings from your bill, tariff and evening usage pattern.

- Discount or rebate line item and whether eligibility has been checked.
- Usable battery capacity in kWh, not just nominal capacity.
- Backup capability, switchboard work and monitoring inclusions.
- Tariff, feed-in rate and household usage assumptions used for savings.
