Your power bill happens after dark.
Between 4pm and 9pm the grid charges up to 3× the off-peak rate, right when your home uses the most. A battery banks cheap daytime power and runs your evenings on it. We give you the honest numbers, then match you with one vetted installer. No spam, no calls until you say so.
The grid's best trick: charging triple at dinner time.
Power prices are not flat. On a time-of-use plan the same electricity that costs around 22c overnight can cost up to 58c between 4pm and 9pm, the exact hours dinner is cooking, the aircon is on and everyone is home. Meanwhile the solar you export at lunch earns you a few cents. That gap is the whole reason batteries make sense.
Indicative market time-of-use rates. Your exact prices depend on your network, retailer and plan; peak windows are commonly 4pm to 9pm on weekdays. "With a battery" shows the hours your stored solar covers instead of the grid.
One quiet box. Three moves. Every day.
A home battery is not complicated. It runs the same play every 24 hours, automatically, with nothing for you to switch and no app to babysit.
Bank your free solar
While you are out, your panels fill the battery with power that would otherwise be sold to the grid for a few cents.
Spend it at the peak
Through the expensive evening window your home runs on stored sunshine instead of 58c grid power. This is where the money is.
Hold through blackouts
With backup wired in, your essentials stay on when the street goes dark. The kettle still works while the neighbours find candles.
Run tonight's numbers on your house.
Your state, your bill, your battery size. Yearly saving, after-rebate price and payback, out in the open where a sales call usually sits. Nobody rings you afterwards.
We show the federal discount and your state incentive separately, never merged into one number.
Estimates only, based on indicative energy prices and rebate values. Your real figures depend on your postcode, retailer, tariff, usage pattern and battery model. A free rebate check returns numbers specific to your home.
About 30% off is live right now. It shrinks every six months.
- The federal Cheaper Home Batteries discount takes roughly 30% off a typical battery, around $2,400 to $3,300 off a 10 to 13 kWh unit, straight off the invoice.
- State incentives are separate and different in every state, a VPP payment in NSW, an interest-free loan in Victoria. We describe them separately, never stacked into one fairytale number.
- With the discount, honest payback lands around 3 to 5 years, then the battery keeps saving well inside its 10-year warranty.
- Built on public data from the Clean Energy Regulator and the AER. If we cannot back a number, we do not print it.
The rebate has already been cut twice in 2026 and steps down again on 1 January 2027. Install before the cut and the bigger discount is locked into your invoice.
The batteries Australia actually installs.
No favourites and no commissions steering the advice. These are the brands installers quote most, with honest after-rebate price ranges.
Aussies sleeping easy on stored sunshine.
"We had panels but were still copping huge winter bills. The battery runs the whole evening now. They matched us with one local installer. No spam, no five calls."
"Didn't realise how many rebates I qualified for until the quiz. Came off the price before I paid a cent. Bill's basically zero through summer now."
"Best part was one installer instead of five hounding me. They picked the right mob for my place and answered all my dumb questions. Power through every blackout now."
Real customers, real results. Individual savings vary with your home, usage and tariff.
Everything worth knowing, before anyone quotes you.
The best defence against being overcharged is knowing your numbers before the salesperson does. Free, ungated, written like a mate would explain it.

Most battery comparison sites sell your phone number to four or five installers who all start calling at dinner time. We watched that play out with solar, along with 270-plus collapsed companies and warranties not worth the paper. My Home Battery, from the Sydney team behind Why Solar, was built to be the opposite on purpose.

- Your details are never sold. What you share with us stays with us. No auctions, no pile-on of cold calls.

- No calls until you say so. Read for ten minutes or ten weeks. Your journey, your pace.
