By day your panels make more than you use, and it goes to the grid for a feed-in rate that keeps dropping. By night you buy it back at full retail. A battery stores the day to spend at night.

-
Daytime
Your panels make more than the house uses. The surplus charges the battery instead of being sold to the grid for a few cents.
-
Evening
When the sun drops and your usage peaks, the house runs on stored solar, not on grid power at full retail.
-
Overnight
The grid stays off until the battery runs down, so you buy far fewer of those expensive night-time kilowatt-hours.

Prices are starting prices for eligible standard residential installations in South East Queensland and include GST. Site-specific items — switchboard upgrades, difficult access, asbestos, long cable runs, network requirements or non-standard backup wiring — can change the final price, which is confirmed in writing before any commitment. The federal battery rebate (Cheaper Home Batteries Program) is applied as a point-of-sale STC discount where the site, customer and equipment are eligible; eligibility is confirmed on the quote call.
Example bill scenarios — your result is calculated before you commit
Two example scenarios, not guarantees: 26 kWh/day usage, 35c/kWh peak, 4c feed-in, plus daily supply charge. Before you commit, we review your bill, usage, tariff and site and give you a written estimate for your home.
$928 Estimated quarterly bill now
$132 Estimated after install
- Annual saving (example)
- ~$3,185/yr
- Indicative payback
- ~4.1 yrs
6.6 kW solar averages ~27 kWh/day, close to a 26 kWh/day home. In this example you import little from the grid; actual imports vary with weather, season and usage.
$548 Estimated quarterly bill now
$132 Estimated after install
- Annual saving (example)
- ~$1,663/yr
- Indicative payback
- ~5.4 yrs
Your solar exports ~17 kWh/day at 4c, then you buy ~16 kWh back at 35c every night. The battery keeps that power — a net gain of ~$4.92/day.
Example scenarios only — individual results vary. Assumes 26 kWh/day usage, 35c/kWh peak rate, $1.10/day supply charge, and 6.6 kW solar averaging ~27 kWh/day in SEQ. Any Solar Sharer benefit depends on retailer tariff eligibility and a smart meter and is not included in these figures.

Taken off your price up front, when you're eligible
The Federal Government's Cheaper Home Batteries Program is applied as a point-of-sale STC discount — no separate application, no waiting on a refund.
- The SOFAR Powerall is on the CEC approved product list.
- Rebate is set at the installation date, not the contract date.
- The rate steps down again in January 2027 — locking in before EOFY secures the current rate.
- Eligibility depends on approved products, SAA-accredited installation, the battery being installed with solar PV, and no prior battery STC claim for the premises. We confirm it on the quote call.

The questions everyone asks
The short version. The full list lives on the FAQ page.
Is $8,990 really the all-in price?
For an eligible standard residential install, yes: the SOFAR Powerall 20 kWh battery, 5 kW hybrid inverter, fitting and commissioning — with the federal battery STC discount applied where you qualify. Site-specific items (such as a switchboard upgrade, difficult access or asbestos) can change the final figure, which we confirm in writing before you commit.
How does the free 25 kWh upgrade work?
Sign before 30 June 2026 and we fit an extra 5 kWh SOFAR module at install — about $3,000 of estimated extra-storage value, at no extra charge, subject to site suitability and quote terms. It applies to every system, battery-only or bundle.
What happens if you miss the two-week install?
We credit you $200 for every week we're late, up to $1,000 — off your invoice or as a direct transfer. The window is 10 business days from cleared deposit, and the schedule is locked the day you pay.
Can you add it to my existing solar?
Most of the time, yes. The Powerall AC-couples to existing PV between 3 kW and 13 kW, so we add storage without ripping out your inverter.
