Battery Retrofit — Our Core Customer

If you've already got solar on your roof, you're our exact customer. Most Northern Gold Coast homes installed solar 5–10 years ago and never added storage. Adding a battery now means you stop exporting power for cents and start using it yourself.

Already got solar?

Perfect — you've already done the hard yards. A battery retrofit slots in next to your existing inverter (Sigenergy) or replaces it with a battery-ready hybrid inverter (Powerwall 3). You qualify for the federal rebate.

Typical job: 1–2 days on site, fixed-price quote upfront.

No solar yet?

The federal rebate requires the battery to be paired with solar. We can install solar + battery in one job — both rebates get stacked, single trip, cleaner install. Or we'll just do the battery if you're sorting solar yourself.

Better together: Most efficient as one job — solar details →

Tesla Powerwall 3 or Sigenergy — Both Are Excellent

We focus on these two because they're the best engineered batteries on the rebate list and we know them properly. No 'whatever's cheapest this week' approach.

T

Tesla Powerwall 3

13.5 kWh · up to 11.04 kW AC continuous

Integrated hybrid inverter, slick app, strong resale story. Best fit for single-phase homes that want one box, one brand, no fuss.

Best for
  • Single-phase homes
  • Customers who want a brand they recognise
  • Simple, fixed 13.5 kWh setup
Honest note: Powerwall 3 is single-phase only. A lot of newer Gold Coast homes are 3-phase — if yours is, Sigenergy is the better pick.

S

Sigenergy SigenStor

Modular 5–48 kWh · Single or 3-phase

Modular stack, native 3-phase, works with mixed-brand solar. The technically better system for most Gold Coast homes if you're not fussed about the badge.

Best for
  • 3-phase homes (most newer GC builds)
  • Larger or growing capacity needs (stackable)
  • Existing solar from a non-Tesla brand
Honest note: Less brand recognition than Tesla — but spec-for-spec it's the better engineered system, and you'll often pay less per kWh.

What We Check Before Recommending a Battery

Before recommending a battery, we look at the whole picture — not just slap on whatever's in stock. The right system depends on what you've already got and what you're trying to achieve.

Solar setup

Solar size in kW, inverter brand and condition, panel layout, and whether the existing system is performing as it should.

Usage patterns

Daily kWh from a recent bill, when you use power (daytime vs night), and what's drawing it (aircon, pool, EV, kitchen).

Switchboard & phase

Single-phase or 3-phase supply, switchboard condition, available space, and whether any upgrades are needed before install.

Backup needs

Which circuits you'd want kept running during a blackout — fridge, internet, garage door, lights, full house — and what's practical.

Install location

Where the battery will physically sit — garage wall, external wall, floor space — with proper clearances, exposure and access.

Future loads

What's coming — EV charging, second AC, pool heat pump, expanding family — so we size with some headroom built in.

How Battery Backup Actually Works

Backup power isn't always automatic for every circuit in the home. It depends on the battery, your switchboard wiring and what you've asked us to wire up.

Some homes only need essentials backed up — fridge, lights, internet, garage door and a few power points. That's enough to keep food safe, the wi-fi alive and the house liveable during a typical Gold Coast storm outage. Other homes want larger backup coverage, including AC on a key circuit or whole-home backup.

We check your switchboard layout, available battery output and total backup load before confirming what can be backed up safely and how the changeover works. There's no point promising whole-home backup if the wiring or the battery can't support it.

Important: Backup is configured during install, not retrofitted later for free. Tell us during quoting what you want kept running and we'll spec it properly.

Handover and Support

After the install is done, we walk you through the basics of how your battery actually works. Not just "here's the app, see ya later".

That includes:

The goal is that you understand how the system works, not just that it's switched on and left behind. If you've got questions a week or a month after install, call us — we don't disappear after the invoice is paid.

SAA-Accredited. Licensed Electricians. No Solar-Cowboy Shortcuts.

Battery install is electrical work first, energy work second. We're already the licensed sparky doing your switchboard, AC and EV charger — adding a battery is the natural fit, and we're SAA-accredited to sign off the federal rebate.

SAA-Accredited Designer & Installer

Solar Accreditation Australia — the body that replaced CEC accreditation in Feb 2024. We hold both battery design and battery install endorsements. That's what unlocks the federal rebate at point of sale.

Licensed Electricians Doing the Work

Battery jobs touch your switchboard, your DC isolators, and often your main supply. We're QLD-licensed electricians, not solar resellers subbing the wiring out. The whole job stays with us.

Rebate Discount at Point of Sale

You don't claim anything — we apply the rebate directly to your quote, then deal with the STC paperwork ourselves. You pay the discounted price on the day, end of story.

Local. SEQ Residential Only.

Based Upper Coomera, residential homes only across the Gold Coast, Logan, South Brisbane and surrounding SEQ areas. When something needs warranty attention or a re-commission, you're calling the same number — not a head office in Sydney.

Accreditation

SAA-Accredited for Battery Design & Install

  • Solar & battery system design
  • Battery installation (storage endorsement)
  • QLD-licensed electrical contractor
  • Licensed Air Conditioning & Refrigeration Technician
  • Tesla & Sigenergy installer pathway

SAA is the Clean Energy Regulator-appointed accreditation body. Without an SAA-accredited installer signing off, the federal rebate can't be claimed.

Can You Claim the Federal Rebate?

The Cheaper Home Batteries Program rules in plain English. If your situation is a 'maybe', send us a photo of your switchboard and we'll tell you straight.

You probably qualify if

  • You own your home (or have owner's approval)
  • You already have working solar, or you're adding solar at the same time
  • You don't already have a battery on this property meter
  • You want a battery between 5 kWh and 100 kWh (rebate caps at 50 kWh)
  • You're OK with the battery being VPP-capable (it doesn't have to be enrolled — just capable)

You can't claim if

  • No solar on the property and not getting it
  • You've already claimed a battery rebate on this meter (one per NMI)
  • The battery is for a caravan, boat, off-grid shed or commercial site
  • The battery isn't on the Clean Energy Council approved product list
  • You self-install or use a non-SAA-accredited installer

Heads up on the QLD Battery Booster: That state program closed in May 2024 and hasn't been relaunched. The federal Cheaper Home Batteries rebate is the only battery incentive currently available to Gold Coast homeowners.

Battery FAQs

How much will I actually save on my power bill?

Well-matched homes may significantly reduce grid imports, but actual savings depend on solar size, battery capacity, household usage, tariff structure, backup requirements and how the system is configured. Payback varies by household — usage patterns, tariff, solar export rate, battery size, rebate eligibility and installation cost all affect the result. We'll talk through realistic expectations for your home during quoting.

Does the battery give me backup if the grid goes down?

Yes — both Tesla Powerwall 3 and Sigenergy can be configured for whole-home or essential-circuits backup. Backup wiring adds a bit of cost depending on what you want to keep running. We'll quote it in or out — your call.

My solar's old. Will a battery still work?

In most cases yes. Powerwall 3 is AC-coupled and works alongside almost any existing solar inverter. Sigenergy can be AC-coupled retrofit or DC-coupled if we're replacing your inverter. Send us a photo of your inverter — we'll tell you which option fits.

Do I have to join a VPP (Virtual Power Plant)?

No. The battery only has to be VPP-capable to qualify for the rebate. You're never forced to join one. Both Tesla and Sigenergy meet the requirement.

Should I wait for prices to come down further?

Rebate values reduce over time as the program winds down toward 2030. Battery prices have stabilised — savings from waiting are typically eaten by the smaller rebate. We'll confirm current eligibility and pricing when you ask for a quote.

How long does install take?

Most retrofit jobs are 1–2 days on site. From signed quote to switched-on is typically 3–6 weeks depending on stock and Energex paperwork.

Do you install other brands?

We stick with Tesla Powerwall 3 and Sigenergy because we know them properly and they're both well-engineered. We won't quote you a brand we don't believe in just to make a sale.
