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.
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 accredited installer, 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 work with proven, quality battery systems suited to Queensland's conditions:
- Tesla Powerwall — 13.5 kWh, whole-home backup capability, strong software integration, excellent track record
- SolarEdge Home Battery — integrates seamlessly with SolarEdge inverters, flexible capacity
- Sungrow SBR — modular, stackable system, strong value proposition
- BYD Battery-Box — modular capacity, AC and DC coupled options
- Enphase IQ Battery — AC-coupled, works with any existing solar system
We don't sell one brand — we recommend the system that best suits your existing inverter, your home's energy profile, and your backup power goals. If you have an existing solar system from another installer, we assess compatibility before recommending a battery.
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.

Frequently Asked Questions
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. Tesla Powerwall, Enphase IQ Battery and certain Sungrow and BYD models include backup. 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.
