Solar battery questions, honestly answered
Costs, rebates, payback, backup power and more — the straight answers Adelaide homeowners ask us most. Still unsure? We're always happy to talk it through.
Everything you need to know
In 2026, installed home battery storage in Adelaide typically ranges from smaller 5–6.5kWh units up to larger 13.5kWh+ systems like the Tesla Powerwall, with stacked systems for high-usage homes costing more. Your exact price depends on capacity, brand, backup requirements, your switchboard and current rebates. We provide a free, fixed, itemised quote based on your actual power bill — no guesswork.
For most Adelaide and SA homes, yes. With some of Australia's highest power prices and very low feed-in tariffs, storing your own solar and using it at night now saves far more than exporting it. Homes with significant evening usage — air-conditioning, electric hot water, EV charging — see the fastest payback, commonly in the 7–11 year range. We'll model your real numbers before you commit.
There's no single best battery — only the best one for your home. We're a Tesla Powerwall Certified Installer and Enphase Premier Installer, and we match the system to your usage, backup needs, budget and roof. The right size and a quality install matter as much as the brand. Tell us about your home and we'll recommend the best fit.
Incentives change over time but commonly include federal capacity-based incentives, upfront discounts, Virtual Power Plant (VPP) programs and interest-free finance. As a Clean Energy Council Approved Retailer we identify which current rebates apply to your address and apply eligible amounts directly to your quote, handling the paperwork for you.
Yes. Most existing solar systems can have a battery retrofitted using a hybrid or AC-coupled setup. It's often more cost-effective than a full new system. We'll check your inverter and switchboard compatibility and recommend the best approach for your setup.
With backup capability, yes. A standard grid-connected solar system shuts down in a blackout for safety, but a battery with backup keeps your home running — either essential circuits (fridge, lights, Wi-Fi) or your whole home, depending on the system. Paired with solar it can even recharge during a daytime outage.
Absolutely. We supply and install solar panels, battery storage, and complete solar-and-battery packages designed together for maximum savings. We also handle upgrades, replacements, maintenance, cleaning and repairs for systems of any brand.
We service the whole Adelaide metropolitan area — northern, southern, eastern and western suburbs — plus the Adelaide Hills, the Fleurieu Peninsula down to Victor Harbor, the Barossa Valley and beyond. As a 100% SA owned and operated team, local service is what we do.
Yes. We're a Clean Energy Council Approved Retailer, a Tesla Powerwall Certified Installer and an Enphase Premier Installer, and we back our work with a 10-year workmanship warranty on top of manufacturer product warranties. Over 1,500 SA systems installed and counting.

Most quality home batteries last around 10–15 years and come with a 10-year warranty that guarantees a minimum retained capacity. Modern lithium iron phosphate (LFP) batteries can be charged and discharged daily for many years, comfortably outlasting their warranty in normal household use.
Most Adelaide family homes suit a 10–13.5kWh battery, which covers a typical evening and overnight load. The right size depends on how much power you use after dark — so we size it from your actual usage data, accounting for air-conditioning, electric hot water and any EV charging.
Yes. With whole-home backup and enough capacity, a battery can run your entire home during a blackout, though large loads like ducted air-conditioning drain it faster. Many homes instead choose essential-circuit backup — fridge, lights, Wi-Fi and power points — as a more cost-effective option.
A battery can be charged from the grid during cheap off-peak periods, but it delivers far more value paired with solar — storing your free daytime generation to use at night. We can retrofit a battery to your existing solar or install panels and a battery together as one system.
A Virtual Power Plant links thousands of home batteries so they can support the grid at peak times. In return, participants receive credits, a better energy plan or upfront incentives. Joining is optional and involves a trade-off over how often your stored energy can be used by the grid.
Solar batteries in Adelaide, in plain English
If you take one thing from these answers, make it this: a solar battery's value comes down to your evening power usage and South Australia's high grid prices. The more power you'd normally buy from the grid at night — running air-conditioning, electric hot water, an EV or a busy family home — the more a battery saves you by covering that usage with stored solar instead. For a lot of Adelaide homes, that now adds up to faster payback than people expect.
The other thing worth remembering is that the right system is the one designed for your home, not the biggest one a salesperson can sell you. An oversized battery you never fully use is wasted money; an undersized one leaves savings on the table. That's why we always start with your real power bill and usage before recommending capacity, brand or backup configuration — and why we'll tell you honestly if storage doesn't stack up for you yet.
Still weighing it up? The best way to get a clear answer is to have us model your actual numbers. It's free, there's no obligation, and you'll come away knowing exactly where you stand — even if the honest answer is to wait.
