Right now the federal rebate is worth about $252 per usable kWh. From 1 January it steps down to roughly $211 — around $550 less on a typical 13.5kWh battery, for exactly the same install. Lock in today's rate while it's still on the table.
Tell us a bit about your place and we'll come back with your exact rebate figure and a fixed price. Same business day, no obligation.
The Cheaper Home Batteries rebate doesn't end — it shrinks, twice a year, every January and July. Most companies mention it in passing. Here's what it actually means for your quote.
The rebate is currently 6.8 certificates per usable kWh. On a 13.5kWh battery that's roughly $3,400 straight off the price.
The rate falls to 5.7 certificates per kWh. Same battery, same install, several hundred dollars less support.
Unlike the solar rebate, the battery rebate reduces twice a year through to 2030. Waiting costs you money every time.
Federal rebate today vs from 1 January 2027, by usable battery size.
| Battery size | Rebate now | From 1 Jan 2027 | You lose |
|---|---|---|---|
| 5 kWh | ~$1,258 | ~$1,055 | $203 |
| 10 kWh | ~$2,516 | ~$2,109 | $407 |
| 13.5 kWh | ~$3,397 | ~$2,847 | $550 |
| 14 kWh | ~$3,522 | ~$2,953 | $570 |
Estimates only. Based on the small-scale technology certificate factor of 6.8 per usable kWh (to 31 December 2026) falling to 5.7 from 1 January 2027, at an assumed certificate price of $37. The full rate applies to the first 14kWh of usable capacity; larger systems taper, so an oversized battery earns proportionally less. Actual certificate prices fluctuate, admin fees vary, and eligibility conditions apply. The rebate is applied up front by your installer. We'll confirm your exact figure in writing before you commit.
Every month you wait, the same battery costs you more. Get the number in writing now, then decide — there's no obligation either way.

Filmed on a recent O'Brien Electrical & Solar install in Townsville.
Chris and the team have been fantastic through the process of having a solar battery added to my existing setup. The installation process went well. A small change in scope was necessary but that was addressed very quickly. The Sigenergy battery they have installed looks good, functions well and I have found the interface very intuitive and easy to use. I also made use of their finance agent for part of the installation and was impressed with their rates and fees. They got us a deal I was very happy with. Overall I would be happy to recommend everyone make use of this business as they have everything from quoting, finance, products and installation nailed down. Thank you again.
10 out of 10!! Excellent company to have install our Solar. They provided a large team who worked really well together, each knowing their role to play. I couldn't fault their professionalism and workmanship, This was a great experience from Day 1, with individualised explanation of how the solar rebates work. Thanks O'brien Electrical and Solar, you guys rock!
This is our third solar install at different addresses. Had mixed experiences previously; but found O'Brien Townsville to be incredibly professional. Chris, the head guy, promptly undertook a site visit before quoting as we had some issues with battery location. Despite their promptness and professionalism, their quote was very competitive. One of the issues with the other earlier suppliers was that they were always putting job off due to lack of stock/supply issues. Obrien delivered on time just before summer heatwave. Their install team were clearly a well-run team and all of them seemed like fine young men invested in their work. Nothing was too much trouble. We appreciated their work immensely - and bought them a couple of cartons of beer for the trip home from Magnetic Island (driver excluded) in appreciation. Couldn't recommend them more highly.

I could not be happier with the service and products supplied. The install team were polite and efficient. Chris and staff have been great with sorting out a few teething issues we were having with our system. I would genuinely recommend this company.
We couldn't' be happier with the team of young tradesmen who installed our solar at Magnetic Island. They worked incredibly hard in extremely hot conditions and never once complained. Their attitude, professionalism and work ethic were outstanding. The quality of their work was excellent. We would highly recommend them to anyone looking for a reliable and hardworking crew.
Could not be happier with our solar installation. Great communication, all the little extras covered like hot water on a smart switch. Installation was smooth and professional. Could not recommend more!
Had a great experience with our solar installation! The installers were fantastic—professional, friendly, and efficient. Communication was clear and consistent from start to finish, and everything was left neat and tidy. Installers provided a thorough run down of the system after the install was completed. Highly recommend!
Very happy with the service. Chris was very helpful, answering my questions even after installation. The price was good too compared to other quotes
Excellent service from the whole team. Well mannered and very professional from start to finish. I do not hesitate to recommend this company for any electrical or solar work.
The team at O'Brien Townsville were exceptional. Great people, great service. No issues.
