May 1st rebate step-down, and why battery prices might keep falling anyway

If you got a battery quote in April and another one this week, the numbers will look different. The federal Cheaper Home Batteries rebate stepped down on 1 May. Quick rundown on what changed and what it actually means if you’re shopping right now.

There’s also a quieter story playing out on the supplier side that might cut the other way.

What changed on 1 May

The rebate that started in July 2025 was never a one-shot thing. It tapers down each year and the schedule was baked in from day one. May 1 was one of those step points.

In practice:

The discount that comes off the upfront price of an eligible battery is smaller than it was last week.
It’s still a meaningful chunk. Just not as big as it was.
Still applied at point of sale. We deduct it from your quote, you don’t pay full whack and wait.
More step-downs are scheduled between now and 2030. Each one is smaller than the last.

Eligibility hasn’t changed. The battery has to be on the approved list, the install signed off by an accredited installer, the paperwork is the same. The Sungrow batteries we put in are still eligible.

I won’t quote a specific dollar amount here because it depends on the size of your battery and where the rebate now sits. Rebate amounts are indicative only and depend on current government rules. When I work up a quote for you it shows the current deduction as a line item, not buried.

So is now a worse time to buy than April?

On the rebate alone, yes, a bit. You’d have got slightly more off in April. But that’s only half the story.

The other half: the supplier side has cooled off

When the rebate launched mid-2025 the phones ran hot. Wholesalers and importers ordered heavy to keep up. By late 2025 / early 2026 a lot of them were sitting on more battery stock than they planned for.

Now the rush has eased back to something more normal, and a few of the brands I deal with are quietly trimming wholesale prices to move inventory. Nothing dramatic, but it’s real.

What I reckon is happening, with the usual caveat that this is speculation, not a guarantee:

The big rush is mostly over. The households getting hammered hardest by power bills moved first.
Suppliers who staffed up and stocked up for that rush now have headroom they didn’t plan for.
That headroom shows up as quiet wholesale price softening, which a fair installer passes through.

So depending on the brand and system size, a quote in May or June 2026 might come out closer to an April quote than the rebate change alone would suggest. Won’t always work out that way. But it’s worth getting a fresh quote rather than assuming the window has closed.

What I’d do if I were buying right now

A few things hold true regardless of which week you pull the trigger:

Get the quote in writing with the rebate as a separate line. You can see exactly what the rebate did vs what the installer charged. Anyone bundling it into one “after rebate” number is hiding the maths.
Hybrid inverter if blackout backup matters. A battery on its own doesn’t run your house in an outage. Covered in detail in the previous post.
Ask what the installer’s paying for the battery at the wholesale level. A straight sparky will tell you roughly. If the answer is vague or the margin doesn’t add up, that’s a tell.
Don’t chase the rebate down to the wire. The next step-down is smaller than this one was. Buying a worse system to grab a slightly bigger rebate is a poor trade.

Bottom line

The rebate is smaller than it was last week. That’s real, and it’ll show up on every quote from now on. But supplier-side pricing is softening at the same time, so don’t assume the total deal got worse by the same amount the rebate shrank. Get the quote, look at the numbers broken out, decide on the final price, not on rebate-headline maths.
