Australia’s Cheaper Home Batteries Program has been available since 1 July 2025. It is not a vague future promise and it is not a generic “$8,000 loan” slogan from early rumour cycles — eligible homes receive an STC-style point-of-sale discount of roughly $372 per kWh of usable battery capacity. This guide explains eligibility signals, stacking with state schemes, quote red flags and how to get CEC-accredited installation quotes through MrSolar.
Tell us about your home. We'll match you with 3 local installers.
Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.
Free for homeowners. Participating installers pay MrSolar a lead fee when matched — that does not buy a higher ranking in our guides or reviews. See how we match quotes and is MrSolar legit?
Think in usable kilowatt-hours. At ~$372/kWh usable, a 10 kWh usable battery is about $3,720 off the installed price before any state support. A 13 kWh usable pack is roughly $4,800 off. Installers must use eligible products and follow Clean Energy Regulator / Clean Energy Council pathways similar in spirit to solar STCs. If a quote shows only “government discount” without usable kWh maths, ask them to recalculate in writing. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots. Usable kWh on the quote must match the capacity the federal discount is calculated on. Save PDFs of every plan, approval and datasheet — warranty claims years later depend on that trail.
Expect requirements around eligible battery products, accredited installation, and documentation that ties the system to your premises. Many households install storage with existing solar or as a combined solar-plus-battery job because self-consumption is the point. Confirm current CER guidance with your installer — program administration details can be updated, but the live status since 1 July 2025 is settled. Renters usually need the property owner on the paperwork. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots. Usable kWh on the quote must match the capacity the federal discount is calculated on. Photograph your switchboard and roof planes before quoting day to cut variation risk.
Victoria’s Solar Homes battery pathway, Queensland’s Battery Booster ($3,000–$4,000 context), South Australia’s Home Battery Scheme, ACT Next Gen storage support and NT battery programs may add state dollars or loan-style support when you meet income and property rules. Stacking is common but not automatic. Itemise federal ~$372/kWh usable separately from state vouchers so you can verify both. NSW and Tasmania homeowners generally lean on the federal discount plus STCs on any paired PV. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots. Usable kWh on the quote must match the capacity the federal discount is calculated on. Save PDFs of every plan, approval and datasheet — warranty claims years later depend on that trail.
Choose usable capacity for your evening load, not the largest cabinet on the truck. Confirm backup circuits if blackout cover matters. Check DNSP re-approval for hybrid or AC-coupled adds on constrained feeders in Adelaide, Sydney and SEQ. Keep serial numbers and assignment forms. A mis-sized battery that rarely cycles still consumes subsidy eligibility without delivering bill savings. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots. Usable kWh on the quote must match the capacity the federal discount is calculated on. Photograph your switchboard and roof planes before quoting day to cut variation risk.
Battery payback depends on retail peak rates, FiT levels (often 2–10c/kWh by state), export limits and how much solar you currently dump. Self-consumption of evening energy at 30–40c/kWh retail is usually worth more than exporting at 5c. With ~$372/kWh usable off the top, modelled paybacks tighten — but interval data beats brochure spreadsheets. Demand a tariff-specific model before you sign. Treat metro 6.6kW after-STC bands (often $5,000–$8,000) as planning ranges only — roof access, switchboard upgrades and network fees move real invoices outside averages. Usable kWh on the quote must match the capacity the federal discount is calculated on. Save PDFs of every plan, approval and datasheet — warranty claims years later depend on that trail.
Only CEC-accredited installers. Only CEC-listed batteries. Three written quotes via MrSolar. Each quote should show usable kWh, federal discount dollars, state support status, warranty labour terms and DNSP steps. Ignore “free battery” advertising — the federal program reduces cost; it does not conjure hardware from nowhere.
