Right now, batteries are cheaper than they have ever been because of the new Cheaper Home Battery Rebate.
You will still see so called 200Ah batteries online for 900 dollars and others for 3500 dollars. But in real solar design, we size homes in kWh, not in Ah.
And the gap between cheap and quality is simple:
Cheap units survive one or two Hervey Bay summers.
Proper systems run 10 to 15 years without drama.
Here is the real shift. With the new government rebate, quality batteries installed by accredited professionals now get a sizeable upfront discount.
Cheap online units do not qualify and do not survive local conditions anyway.
If you live in Hervey Bay with salt air, heat, storms, and rising night-time grid rates, a battery is not a gadget.
It is protection.
It is control.
It is your own stored power at night.
And now, with the rebate, the good systems finally cost less than most people expect.
At O’Brien, most 10 to 15 kWh batteries the same range roughly as the old 200Ah class sit in the expected installed range.
They are smart, expandable, storm-ready, and covered by a 20-year performance guarantee.
The big difference today is simple.
Eligible systems get the government rebate taken off the price immediately.
Long-life batteries are far more affordable than they were last year.

Payback
A correctly sized 10 to 15 kWh battery saves most homes 1500 to 3000 dollars per year.
With the rebate cutting your upfront cost, many homes now reach payback faster than the old 4 to 6 year range.
After that, it is pure freedom from night-time grid rates.
Next Step
If you want accurate pricing and to confirm your eligibility for the rebate, we can check your usage and size the right system.
No generic numbers.
No pushy upsells.
Just a battery that fits your home and your bill.
Is it worth adding a battery to existing solar panels?
That depends on whether you want to use your own electricity Hervey Bay powe or keep renting it back from the grid.
Many Hervey Bay homes already produce more solar energy than they can use during the day. But without a battery, all that excess goes straight back to the grid for a fraction of what it costs to buy it back at night.
The math is clear. A quality solar battery stores what you generate, reduces night-time draw, and protects you during outages.
In Hervey Bay, battery systems matched correctly can reduce your power bill by $1,500 to $3,000 a year, depending on usage. Most pay for themselves in 4 to 6 years.
And unlike older systems, today’s batteries are built for salt air, heat, and storm season. Just like Hervey Bay weather.
Advertising that makes vague claims wastes money. So we test, measure, and install systems that prove their worth under real-world conditions, starting with your roof.
