Home Battery Storage — Noosa, Hinterland & Sunshine Coast
Store the solar energy you generate and use it when you need it most — evenings, peak tariff periods, and grid outages. Federal battery rebate applied directly to your invoice.
A solar system without a battery still leaves you buying power from the grid every evening. Battery storage changes that — you capture the energy your panels generate during the day and use it when it matters most: after dark, during peak tariff periods, and when the grid goes down during hinterland storms. Ultralec installs home battery storage systems across Noosa Heads, Noosaville, Tewantin, Cooroy, Pomona, Eumundi, Gympie and the wider Sunshine Coast, with the federal Cheaper Home Batteries rebate applied directly to your invoice.
Who Actually Installs Your System
- SAA-accredited solar designer and installer — accreditation S7558874. Required by law to design and install any system claiming STC rebates.

- No subcontractors. Ultralec is Alex and his apprentice. The person who designs your system is the person who installs it and the person who comes back if anything needs attention.
- 10-year workmanship warranty — double the 5-year industry minimum. Covers mounting, roof penetrations, wiring, switchboard work and labour.
- 82 five-star Google reviews from real customers across Noosa, the Hinterland and Gympie.
Federal Cheaper Home Batteries Program — What You Get
The federal Cheaper Home Batteries Program delivers an upfront discount on eligible battery installations — no applications, no paperwork, no waiting. As an SAA-accredited solar designer and installer (accreditation S7558874), we generate Small-scale Technology Certificates (STCs) on your behalf and apply the value as a discount directly on your invoice. For a typical 10–13 kWh battery, this represents several thousand dollars off the installed cost.
The rebate structure changed on 1 May 2026 — it now applies the full rate to the first 14 kWh of usable capacity, with reduced rates for larger systems. For most Noosa Hinterland households installing a standard residential battery, the rebate is still very worthwhile. Call us for a current figure based on your chosen system size — the numbers change periodically and we quote them accurately.
Which Battery Systems Do We Install?
We install a deliberately small range of battery systems — the ones we know are reliable in Queensland conditions and that we're happy to stand behind for a decade:
- Sungrow — one of the most widely installed battery and hybrid inverter brands globally, with a long track record and a well-proven ecosystem. The safe choice where you want maximum history behind the product.
- GoodWe — excellent value with a strong hybrid range. A solid option for straightforward residential storage paired with a new or existing solar system.
- Sigenergy — the most capable of the three. The SigenStor system stacks inverter, battery and EV charging into one modular unit, which is a genuinely tidy solution for homes wanting all three without separate boxes on the wall. Where budget allows, it's often what we recommend.
We're not a reseller carrying a huge catalogue. We install a handful of products we know well, because we're the ones who come back if something needs attention. See our Solar & Battery page for the panels and inverters we pair these with.
Adding a Battery to an Existing Solar System
Most existing solar systems can have battery storage added, but the integration approach depends on your current inverter. Some inverters are battery-ready and accept DC-coupled storage directly. Others require an AC-coupled battery — which adds a separate battery inverter. And some older inverters are at end-of-life and are best replaced at the same time as the battery is added.
We assess your existing system as part of every battery quote — we'll tell you exactly what's involved, what it will cost, and what your expected annual saving looks like with the battery added. No surprises.
Backup Power During Outages
The Noosa Hinterland gets serious summer storms. Power outages — sometimes for hours, occasionally for days — are a real part of life on acreage and in rural areas. A properly configured battery system with backup capability keeps your essential circuits running when the grid goes down: lights, fridge, phone charging, internet, and potentially water pumps on tank-fed properties.
Not all batteries provide backup capability — some are grid-tied only and shut down with the grid. We specify and configure systems to provide the backup function where that's a priority for the customer.
Battery Storage + Solar — Installed Together
Installing solar and battery together from the start is the most cost-effective approach — single mobilisation, integrated system design, and no second round of labour costs when you add the battery later. We design and install complete solar-plus-battery systems sized for your household's energy use, roof, and budget. See our Solar & Battery Installation page for full system details.
Battery Storage Coverage
We install battery storage systems across Noosa Heads, Noosaville, Tewantin, Sunshine Beach, Peregian Springs, Cooroy, Pomona, Eumundi, Yandina, Gympie and the surrounding Noosa Hinterland. Quotes provided within 24 hours.
Our Warranty — and Why the Structure Matters
Ultralec provides a 10-year workmanship warranty on every solar and battery installation. That's double the five-year minimum set by the industry code, and it covers the part that's genuinely our responsibility: roof mounting and penetrations, DC and AC wiring, isolators, switchboard work, and the labour to come back and fix anything that arises from how the system was installed.
On top of that, you get the manufacturer warranties on the components themselves — typically 15 years product and 25 years performance on our panels, 10 years on Sungrow, GoodWe and Sigenergy inverters, and 10 years on battery systems. We register these for you at commissioning.
Ask any installer this one question
Most solar companies are retailers. They sell you the system, then dispatch a subcontracted crew to install it. When something goes wrong in year four, the warranty chain gets complicated — the crew that did the work may no longer be engaged by that retailer, and you're left chasing who's actually responsible.
Ultralec is two people: Alex and his apprentice. There is no crew, no subcontractor, no chain. The licensed electrician who designs your system is the same person on your roof, and the same person who answers the phone if you call in eight years. That's not a marketing position — it's just how the business is structured, and it's the single biggest practical difference between us and the larger operators.
Whoever you get quotes from, ask them to put in writing what the workmanship warranty period is, what it covers, and who honours it. It's the most useful question you can ask.

Frequently Asked Questions
We provide a 10-year workmanship warranty covering mounting, roof penetrations, wiring, isolators and switchboard work — double the 5-year industry minimum. Component warranties come from the manufacturers: typically 15 years product and 25 years performance on our panels, and 10 years on GoodWe, Sungrow and Sigenergy inverters and batteries.
No. Ultralec is Alex and his apprentice. The SAA-accredited designer who plans your system is the same licensed electrician who installs it and the same person who returns if anything needs attention. There is no subcontractor and no warranty chain to chase.
Yes — Alex holds SAA accreditation S7558874 as both a solar designer and installer, which is legally required to design and install any system claiming STC rebates. He also holds QLD Electrical Contractor Licence 1502592 and is a Master Electricians Australia member.
Jinko N-type panels as standard with Aiko available as a premium option, paired with Sungrow, GoodWe and Sigenergy inverters and batteries. We deliberately install a small range of proven products with responsive Australian warranty support rather than carrying a large catalogue.
For a typical 10–13 kWh battery, the federal Cheaper Home Batteries rebate currently represents several thousand dollars off the installed cost. The exact figure depends on battery capacity and current rebate rates, which we apply directly to your invoice. Call us for a current number.
Yes — the Cheaper Home Batteries Program applies to both new solar-plus-battery installations and to batteries added to existing solar systems. The rebate is applied as an upfront discount on your invoice — no paperwork on your end.
Some battery systems offer backup capability and some don't. Sungrow, Sigenergy and certain GoodWe systems can be configured with backup capability. We configure backup-capable systems to provide power during grid outages — important for hinterland properties that experience storm outages.
In most cases yes, but the integration approach depends on your current inverter. We assess your existing system as part of the battery quote and recommend the right coupling approach — DC or AC — for your setup.
It depends on battery capacity and which loads are running. A 10 kWh battery running essential circuits — fridge, lights, phone charging — will typically last 12–24 hours. Running air conditioning significantly reduces this. We model expected backup duration as part of the quote.
A battery alone (without solar to charge it) provides very limited financial benefit — it can shift tariff consumption but the economics are marginal. Battery storage makes the most sense paired with solar. If you don't have solar yet, a solar-plus-battery package installed together is the most cost-effective approach.
