As at November 2026 the company holds 4.5 stars from about 430 Google reviews, 4.3 from 128 on ProductReview.com.au and 3.9 from only 13 on Trustpilot. Aussie Solar Batteries (also called Aussie Solar Batteries Group) is a trading name of Solar System Pty Ltd, ABN 91 619 655 051, which sells Sumray, Fox ESS and other batteries in NSW, Queensland, Victoria and South Australia. Our verdict: legitimate and well rated for installs, with a clear pattern of delay and communication complaints. This is independent desk research; we did not contact the company and were not paid.

Is Aussie Solar Batteries any good?
Aussie Solar Batteries looks like a real, established, high-volume battery retailer with generally good install feedback. Its Google score of 4.5 is below the 4.8 average we see across rated installers in our directory, but it rests on a much larger review count than most, and review text repeatedly praises tidy, fast installs.
The weaknesses are about what happens before and after the install. Reviewers describe slow or missed install dates, hard-to-reach support after signing, and extras that were not obvious in the quote. The Trustpilot score is much lower than the other two, but it rests on 13 reviews, so treat it as a warning to read the contract rather than as a verdict.
The company says it has “1000+” five-star reviews. It names no platform for that figure, and the platforms we could read show averages below 5, so we do not use the claim. Our own take on why star ratings alone are weak evidence is in the five-star problem.
Aussie Solar Batteries ratings by platform
Ratings across the three public platforms range from 3.9 to 4.5. The count behind each number matters more than the number.

| Average rating | |
|---|---|
| Google (about 430) | 4.5 stars |
| ProductReview.com.au (128) | 4.3 stars |
| Trustpilot (13) | 3.9 stars |
Google and ProductReview agree on a score of 4.3 to 4.5; Trustpilot is lower but has too few reviews to be reliable.

What customers praise
Positive reviews on ProductReview.com.au and Trustpilot, read in November 2026, cluster around five themes.
- Fast installation. Several reviewers describe installs within one to two weeks of signing, sometimes well inside the contract window.
- Tidy, professional installers. Reviewers describe neat work, large crews and a walk-through of the app at handover.
- Quoted price matched the advertised price. A few say the quote matched the ad.
- Low-pressure sales and no deposit. Some reviewers say no deposit was needed.
- Monitoring help. Reviewers mention staff setting up charge and discharge schedules.
Common Aussie Solar Batteries complaints
The complaints below are patterns in public reviews, not findings of fact. We name the platform and do not quote individual reviewers.
- Installation delays (ProductReview, Trustpilot). Some reviewers report waits of several months against a promised 6 to 8 weeks, and a few say contracts lapsed after long waits.
- Poor communication after signing (ProductReview, Trustpilot). Unanswered emails and calls, including during grid connection applications.
- Extras not clear in the quote (ProductReview, Trustpilot). Examples reviewers give are an inverter upgrade, a three phase connection fee, a distance-based installation fee and a disconnection fee.
- No pre-install site visit (ProductReview). Reviewers say the installation spot was not checked beforehand, which led to rework on the day.
- Invoicing errors (ProductReview). Repeat requests for payments already made.
How the company responds is hard to see: Trustpilot states the company has not replied to negative reviews, and we saw no company replies on ProductReview, though one reviewer says a complaint was resolved and updated their review.
The share of 1 star reviews on Trustpilot shows how split the small sample is.

Trustpilot reviews of Aussie Solar Batteries split sharply: 54% are 5 star and 31% are 1 star, with nothing in between.
Products and brands Aussie Solar Batteries installs
From its site navigation and product pages, the company sells Sumray modular batteries paired with Solis hybrid inverters, Fox ESS batteries, HGNESS with Solinteg or Solis inverters, Each Energy batteries and other high-capacity systems. The Sumray page lists a module of 13.92 kWh, towers of up to 55.68 kWh and a 15 year warranty document, as stated by the company. We found no independent test of Sumray in Australia, so treat durability claims such as “10,000+ cycles” as manufacturer claims.
We have reviewed two of the brands: see our Fox ESS battery review and Fox ESS battery prices, and the Solis inverter review. For safety, the company says installs follow AS/NZS 5139; read are solar batteries safe for what to check.
Aussie Solar Batteries prices
Aussie Solar Batteries does not publish prices on the pages we could read in November 2026 (its bundle page is password protected). Reviewers mention quotes for batteries of 28 kWh and 42 kWh, but we could not verify any figure.
For context, our battery cost guide gives indicative installed prices of $9,000 to $13,000 for 10 kWh and $16,000 to $25,000 or more for 20 kWh or larger, before rebate, and large battery prices covers 30 to 50 kWh.
Solar Cobber calculation: what the federal discount is worth on a big battery
Large batteries, the company’s focus, earn much less discount per kWh than small ones. Under the Cheaper Home Batteries Program, installs from 1 May to 31 December 2026 earn 6.8 certificates (STCs) per usable kWh, but only 100% of that for the first 14 kWh, 60% for the next 14 kWh, 15% for kWh 28 to 42 and nothing above 50 kWh (see our rebate guide). With certificates worth $38 to $40 each:
- 14 kWh: 14 x 6.8 = 95.2 STCs, or $3,618 to $3,808.
- 28 kWh: 95.2 + (14 x 6.8 x 0.6 = 57.1) = 152.3 STCs, or $5,788 to $6,093.
- 42 kWh: 152.3 + (14 x 6.8 x 0.15 = 14.3) = 166.6 STCs, or $6,331 to $6,664.
- At $38 per STC
- At $40 per STC
Source: Solar Cobber calculation from the Cheaper Home Batteries Program factor and size tiers. Usable capacity, before rounding down to whole certificates.
View the data as a table
| At $38 per STC | At $40 per STC | |
|---|---|---|
| 14 kWh | A$3,618 | A$3,808 |
| 28 kWh | A$5,788 | A$6,093 |
| 42 kWh | A$6,331 | A$6,664 |
The discount rises with size, but far slower than the battery. Per usable kWh it drops from about $258 to $272 at 14 kWh to about $151 to $159 at 42 kWh.
Source: Solar Cobber calculation: total discount divided by usable kWh, mid-point of $38 and $40. Rounded to the nearest dollar.
View the data as a table
| Discount per usable kWh | |
|---|---|
| 14 kWh | A$265 |
| 28 kWh | A$212 |
| 42 kWh | A$155 |
This is why a very low sticker price on a 42 kWh battery cannot be judged without the written breakdown. The figures use usable capacity, which can be lower than the nominal size on a datasheet, and a battery above 50 kWh earns nothing extra.
Warranty and after-sales support
Aussie Solar Batteries does not state a workmanship warranty on the pages we could read. Its Safety and Warranty page links to manufacturer warranty documents for Fox ESS and Each Energy, and the Sumray page names a 15 year warranty, without terms we could confirm. The workmanship warranty is the installer’s promise, so ask for the length and the conditions in writing.
If the installer stops trading, workmanship cover can disappear and manufacturer cover can become hard to claim. Read our company failures tracker and ask who backs the warranty.
Company background
Solar System Pty Ltd registered its ABN on 9 June 2017 and has been registered for GST since 14 November 2019, according to ABN Lookup in November 2026. The company says it has completed more than 16,000 systems since 2017 and installed 105.6 MWh of batteries in April 2026; these are company claims we could not verify. It says it is accredited and lists state electrical licence numbers (NSW, ACT, Queensland, South Australia, Victoria). Check these on the Clean Energy Council approved retailer list (New Energy Tech Consumer Code) and the Solar Accreditation Australia installer register, and the state regulator’s licence search.
We found no public enforcement action against Aussie Solar Batteries or Solar System Pty Ltd as at November 2026. Our search was of public web results, not a court database, so this is not a clean bill of health.

Who Aussie Solar Batteries suits, and who should look elsewhere
