Home Battery Installation — Upper Coomera

Who This Is For — Upper Coomera Homeowners

Upper Coomera is our base — we live and work here. The job we get called out to most often in the suburb is a battery retrofit onto solar that's already on the roof.

If you fall into that group — solar working well, power bills creeping back up, looking at an EV soon, or just sick of selling cheap export power back to the grid — a battery is the natural next step.

Common Upper Coomera Battery Jobs

The typical job we quote in Upper Coomera looks like one of these:

• Single-phase home with existing solar — Tesla Powerwall 3 (13.5 kWh) is a straightforward fit
• 5–10 kW solar, no battery, 3-phase newer build — Sigenergy SigenStor 12–24 kWh works better with 3-phase native handling
• EV in the garage (or coming) — bigger system (16–24 kWh) so the EV doesn't drain the house overnight
• Older solar with ageing inverter — combine inverter replacement with battery for one tidy job

Why Going Local Matters

We're based in Upper Coomera, minutes from most streets in the suburb. That means:

• Faster site visits for tricky quotes
• Local knowledge of Energex paperwork on the Coomera substation
• Familiar with the common house types — Stockland Coomera Town Centre estates, older Pacific Pines-Upper Coomera border builds, newer Reserve Road developments
• Same number to call if you need warranty attention down the track

The Federal Rebate

Eligible installs may receive the federal Cheaper Home Batteries rebate as an upfront discount applied to your quote. We're SAA-accredited so we can sign it off where eligibility is met. Final rebate value depends on usable capacity, system eligibility, STC value and install date — we'll confirm in your quote.
