Home battery storage Adelaide, energy independence after dark
Energy independence,
without the bargain-bin shortcuts.
South Australia has the best battery economics in the country, and a once-in-a-decade federal rebate is on the table. We install premium batteries that will still be working in 2040.

Why batteries now
Three reasons 2026 is the year to put one on the wall.
The federal rebate window is open.
The Cheaper Home Batteries Program is live: typically $4,000-$8,000 off a residential battery, depending on size. We apply it directly to your quote.
SA’s grid charges punish exports.
Feed-in tariffs are 3-6c/kWh and falling. Battery storage lets you use your own solar at the evening peak instead of selling it back for cents.
Premium batteries last twice as long.
A $9,000 bargain battery that dies in seven years isn’t cheaper than a $14,000 Sigenergy or Tesla that lasts fifteen. We install batteries you don’t replace.

Different households.
Tesla Powerwall 3
The proven, simpler choice
13.5kWh usable · Integrated inverter · 10-year warranty
The Powerwall 3 is the solution some households opt for when seeking premium storage without the fuss. The solar inverter is built in, one less box on the wall, and Tesla's app is one of the most polished. At 13.5kWh it covers the evening peak for most Adelaide homes, and paired with the Tesla Gateway it'll carry your essentials (or your whole home, with the right set up by Twilight) straight through a blackout.
13.5kWh usable capacity per unit
Built-in solar inverter (saves another box on the wall)
Whole-home backup ready with the right gateway
Tesla app: clean, mature
10-year warranty
Sigenergy SigenStor · Most flexible
The ecosystem play
Modular 5-48kWh · AI energy management · V2G-ready
If you have an EV (or are thinking about one), or want to grow the system over time, Sigenergy gives you one ecosystem managing solar, battery, EV charging and (when it lands) V2G.
Modular: start at 5kWh, stack to 48kWh
AI-driven smart energy management
EV charger integration via the mySigen app
V2G-ready hardware (when regulator approves)
10-year warranty
Both are excellent. Tesla is the simpler, proven choice. Sigenergy gives you more flexibility if you’re already thinking about EV charging or growing the system later.
Backup & resilience
What “backup”
actually means
when the grid drops.
There are three levels of battery backup. We’ll be honest about what your wiring, your switchboard and your budget can support.
Level 1
Essential circuits only
Fridge, lights, internet, a couple of power points. The simplest, cheapest backup configuration, good for most homes.
Level 2
Whole home, soft start
The battery powers everything but won’t start big loads (air-con, oven) at the same time. Tesla Powerwall 3 with the right gateway, or a properly sized Sigenergy.
Level 3
Whole home, no compromises
Run everything, including ducted aircon. Requires a larger battery, a beefier gateway, and a switchboard that’s up to the job. We’ll tell you upfront if your home suits this.
An honest note: a battery won’t run your whole house on solar alone indefinitely. Even a 24kWh battery is one cloudy day from empty. Backup is about getting through the blackout in comfort, not surviving the apocalypse.

Pricing & rebates
Federal rebate already deducted. SA incentives stacked on top.
The federal Cheaper Home Batteries Program runs from 1 July 2025. Rebate value depends on usable kWh, we calculate it for your specific system and deduct it from your quote.
If any SA-specific incentives apply (the SA Home Battery Scheme has wound down, we’ll tell you honestly if there’s anything left to claim), we’ll handle that paperwork too.

Five steps. You sign once. We do the rest.

After the site visit, we lock in a fixed price: battery model, federal rebate already deducted, payment terms clearly set out. If we find anything unexpected (older switchboard, non-compliant wiring), we flag it before quoting.
Approvals & rebates
We handle the SAPN grid connection application and the rebate paperwork. You don’t lift a finger.
Install
One to two days on site. Done by our in-house SAA-accredited team. Switchboard tidy when we leave.
