Whether you are pairing a battery with an existing rooftop system or commissioning a full solar-plus-storage setup from scratch, the inverter compatibility, battery chemistry, and installation approach all determine how well the system performs over a 10-year warranty period. Our network of CEC-accredited installers helps you get the design right the first time. ### Why use a CEC-accredited battery installer? - CEC accreditation is required to access government battery rebates in participating states - Grid-connected battery systems require a licensed electrical contractor - Correct battery sizing based on your actual load profile, not just panel output - Inverter compatibility checked before purchase — AC-coupled vs DC-coupled systems differ significantly - Manufacturer warranties require accredited installation to remain valid ### AC-coupled vs DC-coupled — what your installer will assess If you already have a standard string inverter, adding a battery usually means AC-coupled storage — a separate hybrid or battery inverter is added alongside it. If you are building a new system or replacing your inverter, a DC-coupled hybrid inverter handles both the panels and battery in one unit and is generally more efficient. Your installer will check your current inverter brand and switchboard capacity before recommending a path. ## Frequently asked questions ### How much does solar battery installation cost in Australia? A typical residential battery system costs between $8,000 and $18,000 fully installed, depending on usable capacity, battery brand, and whether the inverter needs replacing. A 10 kWh system (e.g. Sungrow SBR, BYD HVS, or similar) with a compatible hybrid inverter sits roughly in the $10,000–$14,000 range. A Tesla Powerwall 3 (13.5 kWh, built-in inverter) generally runs $13,000–$17,000 installed. State rebates — where available — can reduce the out-of-pocket cost by $1,000–$4,000. ### What size battery do I need? A useful starting point is your average evening and overnight consumption — typically 5–15 kWh for an Australian household. A 10 kWh usable battery covers most homes through a typical evening peak. If you have an EV, pool, or ducted air conditioning running at night, sizing up to 13–20 kWh makes sense. Your installer will model your actual usage data rather than guessing. ### Does my existing solar inverter work with a battery? It depends on the brand and age. Many modern inverters are hybrid-ready and just need an approved battery connected. Older string inverters often require an AC-coupled battery inverter added in parallel. A small number of very old systems may be more cost-effective to upgrade entirely. Your installer will confirm compatibility during the site assessment — it is not safe to assume. ### Are there government rebates for battery storage? State-level battery rebates exist in Victoria (SolarHomes), South Australia (Home Battery Scheme), the ACT, and Queensland at various times. Eligibility, rebate amounts, and approved product lists change frequently. Your installer will confirm current availability — but always check the official state energy website as well, as some schemes are income-tested or capacity-limited. ## Cities - [Solar Battery Installation in Melbourne](https://www.supertrades.com.au/solar-battery-installation/melbourne) - [Solar Battery Installation in Geelong](https://www.supertrades.com.au/solar-battery-installation/geelong) - [Solar Battery Installation in Canberra](https://www.supertrades.com.au/solar-battery-installation/canberra) - [Solar Battery Installation in Sydney](https://www.supertrades.com.au/solar-battery-installation/sydney) - [Solar Battery Installation in Newcastle](https://www.supertrades.com.au/solar-battery-installation/newcastle) - [Solar Battery Installation in Wollongong](https://www.supertrades.com.au/solar-battery-installation/wollongong) - [Solar Battery Installation in Central Coast](https://www.supertrades.com.au/solar-battery-installation/central-coast) - [Solar Battery Installation in Brisbane](https://www.supertrades.com.au/solar-battery-installation/brisbane) - [Solar Battery Installation in Sunshine Coast](https://www.supertrades.com.au/solar-battery-installation/sunshine-coast) - [Solar Battery Installation in Gold Coast](https://www.supertrades.com.au/solar-battery-installation/gold-coast) - [Solar Battery Installation in Townsville](https://www.supertrades.com.au/solar-battery-installation/townsville) - [Solar Battery Installation in Cairns](https://www.supertrades.com.au/solar-battery-installation/cairns) - [Solar Battery Installation in Darwin](https://www.supertrades.com.au/solar-battery-installation/darwin) - [Solar Battery Installation in Perth](https://www.supertrades.com.au/solar-battery-installation/perth) - [Solar Battery Installation in Adelaide](https://www.supertrades.com.au/solar-battery-installation/adelaide) - [Solar Battery Installation in Hobart](https://www.supertrades.com.au/solar-battery-installation/hobart) Tradespeople: Install solar batteries?
