There is no single Australia-wide solar inverter rebate that automatically applies in 2026. A new eligible solar PV system may qualify for Small-scale Technology Certificates (STCs), with the value generally reflected in an installer’s quote, while a replacement inverter on its own may not qualify. Some states, territories or energy providers may offer separate assistance, and battery incentives have different rules. Check the current details on energy.gov.au and with your electricity provider or a qualified solar installer, as eligibility and any discount depend on the equipment, installation and your location.
