SOFAR Battery Prices and Installation Costs in Australia

SOFAR Battery Prices and Installation Costs in Australia

SOFAR battery pricing depends on the inverter, storage capacity, electrical phase and work needed at your property. Compare the final installed price with the same backup and installation scope, rather than judging packages by the advertised battery size alone.

SOFAR package starting prices

The following November 2026 starting estimates are in Australian dollars, include GST and assume applicable federal incentives have already been deducted. They are indicative metropolitan NSW package estimates, subject to eligibility, availability, site assessment and a written quote.

“30 kWh” is a rounded package description, not a statement of usable capacity. Your quote should identify the battery revision, module count, compatible inverter and control equipment, together with nominal and usable energy. Smaller storage configurations can also be assessed.

What should an installed quote include?

• Exact battery and inverter model numbers, mounting and control equipment.

• Electrical installation, protection, testing and commissioning.

• Connection application responsibilities and any metering costs.

• Monitoring setup and customer handover.

• Any backup equipment and the specific circuits it supplies.

• GST, incentive deductions, exclusions and the final payable amount.

Do not assume essential-circuit backup, switchboard work or unlimited cable runs are included unless the written scope says so. Use our solar quote checklist to compare proposals consistently.

What changes the price at your property?

Switchboard condition: old protection equipment, restricted space or a meter board requiring specialist treatment can add work. Our switchboard upgrade guide explains the assessment.

Location and access: long cable routes, trenching, mounting work and difficult access can affect labour and materials. The battery needs a compliant position, not simply the closest spare wall.

Backup requirements: keeping selected lights and refrigeration available is a different design from supporting large air conditioners or other high-power loads. Phase configuration and starting current also matter.

Existing equipment: retaining a suitable solar inverter creates a different project from replacing it. Our inverter replacement guide covers that decision, while our Wollongong battery cost guide provides broader local cost context.

How the federal battery discount works

For eligible installations from May to December 2026, the published STC factor is 6.8. It applies at 100% to the first 14 kWh of usable capacity, 60% to the portion above 14 up to 28 kWh, and 15% to the portion above 28 up to 50 kWh. These percentages apply to the certificate calculation, not directly to the purchase price.

The dollar deduction depends on certificate value and the eligible system. Use our battery rebate calculator as an estimate and ask your quote to state the installation-date assumptions. Do not deduct a second rebate from a price already shown after incentives.

Compare capacity and output separately

A 20 kWh battery stores energy; a 20 kW rating describes power. When comparing prices, ask for both usable storage and continuous output. A larger battery does not automatically increase the power available to appliances.
