There is no single Australia-wide rebate specifically guaranteed for buying or replacing a solar inverter in 2026. The federal Small-scale Renewable Energy Scheme generally provides incentives for eligible new solar PV systems, rather than a standalone inverter replacement, while state and territory programs may offer support linked to batteries, upgrades or virtual power plants. Eligibility, approved products and rebate amounts can change and are assessed under each scheme’s rules. Check energy.gov.au and your state or territory government website, then confirm the options with an accredited solar installer before ordering work.
