Growatt is a Chinese inverter and battery maker, founded in 2011 and headquartered in Shenzhen, that sells budget string inverters, hybrid inverters and APX battery stacks in Australia through Growatt New Energy Australia Pty Ltd. As at November 2026, SolarQuotes owners rate Growatt inverters 4.4 out of 5 (807 ratings), below Sungrow, GoodWe, Fronius and Fox ESS at 4.8.
The short verdict: Growatt hardware is cheap and widely installed, but its battery warranty is weak and its local support has a mixed record. It suits buyers who have a good installer. This is independent desk research; Solar Cobber was not paid by Growatt and did not contact the company.
Key facts
- Growatt was founded in 2011 and is headquartered in Shenzhen, China, with David Ding as chief executive, according to SolarQuotes.
- Growatt filed a third application to list on the Hong Kong Stock Exchange on 16 June 2026; we found no evidence in November 2026 that it had listed, so treat it as a private company.
- Growatt New Energy Australia’s warranty procedures give grid-connected and hybrid inverters from 1.5 kW to 133 kW a standard 5 years, extendable by a further free 5 years if the owner registers online.
- The Growatt APX HV battery carries a 10 year Australian warranty that guarantees only 70% of capacity for years 1 to 5 and 50% for years 6 to 10, with an allowance of about 300 full cycles a year.
- SolarQuotes rates Growatt inverters 4.4 out of 5 from 807 ratings and Growatt batteries 4.6 out of 5 from 111 ratings (read November 2026), and does not list Growatt among its recommended inverter brands.
- Growatt has had two Australian inverter recalls: the 8000 MTL-S in 2021 and six SPH hybrid models (SPH3000TL to SPH6000TL BL-UP) in late 2023.

Growatt describes energy storage as its largest business: Chinese trade press covering the 2026 listing filing reported that storage now makes up more than 60% of its revenue (we did not read the prospectus). In Australia it remains best known for low-priced inverters.
Growatt products in Australia
Growatt’s Australian range is built from inverters that can be paired with APX HV batteries. The table lists the lines most Australian quotes use; confirm exact model codes on your quote, the Australian datasheet and the Clean Energy Council lists.
| Line | What it is | Power | Notes |
|---|---|---|---|
| MIN TL-X | Single-phase string inverter | 2.5 to 6 kW | Dual MPP trackers, max efficiency 98.4% on the MIN 2500 to 6000 XH datasheet |
| MIN TL-XH (XH2) | Single-phase hybrid inverter | 2.5 to 6 kW | Pairs with APX HV single-phase (S0) batteries; blackout backup needs a separate Backup Box |
| MOD TL3-X, MOD-HU | Three-phase string and hybrid | 5 to 15 kW | MOD-HU has built-in backup output and pairs with APX S2 batteries |
| MID | Larger three-phase | Larger than MOD | Used on bigger homes and small commercial systems |
| SPH, SPF | Low-voltage hybrid and off-grid inverters | 3 to 6 kW (SPH BL-UP) | SPH BL-UP models were recalled in 2023; SPF 3000 to 5000 is Growatt’s off-grid range (SolarQuotes, 2023) |
| Growatt battery | Voltage | Module | Capacity per stack | Works with |
|---|---|---|---|---|
| APX HV (APX 5.0P to 30.0P, S0 and S2 AU) | High voltage | 5 kWh | 5 to 30 kWh | MIN-XH (single phase); MOD-XH, MID-XH, MOD-HU, MID-HU (three phase) |
| ALP LV | 51.2 V low voltage | 5 kWh | 5 to 50 kWh | SPH-HUB and SPA hybrids |
| APX 2.0 (APX M-S3) | High voltage | 7 kWh | 7 to 84 kWh | MOD-HU; we could not find it on the CEC list in October 2026 |
Our reviews cover the detail: the Growatt APX HV battery review and the Growatt inverter review. The older ARK batteries are no longer on Growatt’s Australian product list. For how hybrid inverters work see what is a hybrid inverter, and for the wider market see our best solar inverters and best hybrid inverters guides.
Growatt prices in Australia
Growatt does not publish retail prices, so every figure here comes from third parties. The price of a Growatt APX HV is about A$343 to A$650 per kWh after the federal discount, depending on size and on whose list you use, as at November 2026.
The chart compares two sources, both after the federal Cheaper Home Batteries discount. SolarQuotes lists approximate hardware prices (page last updated 12 May 2026, read 14 November 2026). Austar Solar, one installer, published installed ranges in October 2026; we took the mid-point and subtracted the discount estimate from our APX review.
- SolarQuotes hardware
- Austar installed
Source: SolarQuotes battery cost page (read 14 November 2026); Austar Solar APX price table (October 2026). Solar Cobber calculation: SolarQuotes price divided by nominal kWh; Austar mid-point (for example A$8,000 less A$2,520 for 10 kWh) divided by kWh.
View the data as a table
| SolarQuotes hardware | Austar installed | |
|---|---|---|
| 10 kWh | A$650 | A$548 |
| 15 kWh | A$533 | A$405 |
| 20 kWh | A$450 | A$354 |
| 25 kWh | A$420 | A$343 |
| 30 kWh | A$433 | A$368 |
Price per kWh falls from about A$650 for 10 kWh to about A$420 to A$430 at 25 to 30 kWh on SolarQuotes numbers, and the Austar installed figures are lower again. The two sources do not agree because they measure different things (hardware list against one installer’s installed range) and were published five months apart, so treat the gap as the realistic spread and get written quotes.
| Stack | SolarQuotes hardware after discount | Austar installed before discount | Estimated discount | Austar after discount (mid-point) |
|---|---|---|---|---|
| APX HV 10.0 | A$6,500 | A$7,500 to A$8,500 | A$2,520 | A$5,480 |
| APX HV 15.0 | A$8,000 | A$9,000 to A$10,500 | A$3,670 | A$6,080 |
| APX HV 20.0 | A$9,000 | A$10,500 to A$12,500 | A$4,430 | A$7,070 |
| APX HV 25.0 | A$10,500 | A$12,500 to A$15,000 | A$5,180 | A$8,570 |
| APX HV 30.0 | A$13,000 | A$15,500 to A$18,000 | A$5,710 | A$11,040 |
The federal discount per kWh falls from 6.8 to 5.7 certificates on 1 January 2027, so quotes valued before that date will rise. See our federal battery rebate guide, state battery rebates and battery cost guide.
How Growatt compares on price
On a like-for-like list-price basis Growatt is not the cheapest battery per kWh, despite its reputation. At about 20 kWh, SolarQuotes lists Sigenergy and Fox ESS well below Growatt, and BYD and Sungrow above it.
Source: SolarQuotes battery cost page, last updated 12 May 2026, read 14 November 2026. Solar Cobber calculation: A$4,900/18, 5,100/18.64, 7,800/20.2, 9,000/20, 10,600/19.3 and 11,000/19.2 kWh.
View the data as a table
| Price per kWh | |
|---|---|
| Sigenergy SigenStor 18 kWh | A$272 |
| Fox ESS EQ4800 18.64 kWh | A$274 |
| AlphaESS G3 20.2 kWh | A$386 |
| Growatt APX HV 20 kWh | A$450 |
| BYD HVM 19.3 kWh | A$549 |
| Sungrow SBR 19.2 kWh | A$573 |
The Growatt APX HV lists at A$450 per kWh at 20 kWh against A$272 to A$274 for Sigenergy and Fox ESS, so the “cheap Growatt” label depends on the quote, not the brand. If an installer’s Growatt quote is lower than a comparable Sigenergy or Fox ESS quote, ask what is missing (backup box, inverter, installation). See our Fox ESS Australia guide, Sungrow Australia guide and GoodWe Australia guide.
Warranty and Australian support
Growatt’s inverter warranty is competitive for the budget end, but its battery warranty is among the weakest in Australia. The company’s Australian warranty claim procedures set the standard periods below, read in November 2026.
- Standard
- With free extension
Source: Growatt New Energy Australia, Growatt Warranty Claim Procedures AU/NZ, read November 2026.
View the data as a table
| Standard | With free extension | |
|---|---|---|
| PV and hybrid inverters | 5 years | 10 years |
| Lithium batteries (limited) | 10 years | 10 years |
| EV chargers (THOR) | 3 years | 3 years |
| Off-grid inverters | 2 years | 2 years |
Growatt inverters get 5 years as standard, or 10 years if the owner registers for the free extension; batteries get 10 years but on limited terms; EV chargers get 3 years and off-grid inverters 2. Ask your installer to register the extension and give you the confirmation.
The warranty runs from the installation date on the installation certificate, and is capped from the delivery date (for inverters, SolarQuotes says no more than five and a half years from delivery). The battery terms are stricter, and are set out in our APX review:
- Capacity: 70% of nominal for years 1 to 5, then 50% for years 6 to 10.
- Usage cap: about 300 full cycles a year, or 1,350 kWh a year per 5 kWh module.
- Monitoring: if the system is not kept on Growatt monitoring, the term falls to 3 years.
- Years 6 to 10: Growatt may choose a pro rata buyback instead of a repair.
Source: Brand Australian warranty documents as summarised in the Solar Cobber battery reviews, October 2026.
View the data as a table
| Capacity guaranteed at year 10 | |
|---|---|
| Fox ESS EQ4800 | 70% |
| Sungrow SBR | 70% |
| GoodWe Lynx F G2 | 70% |
| Growatt APX HV | 50% |
Growatt guarantees 50% of capacity at year 10 against 70% for Fox ESS, Sungrow and GoodWe. SolarQuotes founder Finn Peacock wrote that a Growatt battery cycled fully every day effectively turns the 10 year warranty into about 13 months (his review covered the older ARK series; the APX allowance is similar in spirit but different in numbers, and we calculate that a daily full cycle exceeds it by about 22% a year).
If your installer closes, the warranty remains with Growatt, which lists Australian support on 1800 476 928 and australia@ginverter.com. A 2023 SolarQuotes installer opinion reported that Growatt Australia pays a set amount toward warranty service calls, but also that support calls went unanswered during one case; whether service is quick in your case depends on who installed it. Check our company failures tracker and inverter repair and replacement cost guide.
Is Growatt any good?
Growatt is a cheap, widely used brand with improving products and a mixed support record, and it is better as a considered budget choice than as a first-choice premium one. The evidence below is public; Solar Cobber has not tested any Growatt product.
In its favour. Growatt inverters have 807 SolarQuotes owner ratings averaging 4.4 out of 5, and SolarQuotes reports that installers it respects describe modern Growatts as solid with only a handful of failures. The APX HV is IP66 rated and all 12 AU configurations are on the Clean Energy Council battery list to 31 December 2027. Several owners on SolarQuotes report five to ten years of trouble-free running.
Against it. SolarQuotes says Growatt is not on its recommended inverter brands chart because of hit-and-miss reliability and ongoing support issues. Owners report the ShinePhone app misreporting figures and slow handovers after low-cost installs. The battery warranty is the weak point described above.
Source: SolarQuotes inverter review pages, read 14 November 2026 (Growatt 807 ratings, Sungrow 5,483, GoodWe 4,087, Fronius 9,363, Fox ESS 233, SMA 1,529, Solis 382, Huawei 1,305). SolarQuotes ratings come mainly from customers of its installer network, so they skew positive; use them to compare brands, not to read absolute quality.
View the data as a table
| Average owner rating | |
|---|---|
| Huawei | 4.9 |
| Sungrow | 4.8 |
| GoodWe | 4.8 |
| Fronius | 4.8 |
| Fox ESS | 4.8 |
| SMA | 4.6 |
| Solis | 4.5 |
| Growatt | 4.4 |
Growatt has the lowest SolarQuotes owner rating of the eight brands shown, 0.4 below Sungrow, GoodWe, Fronius and Fox ESS. SolarQuotes said in 2024 that Growatt’s reviews average 4.7 over the last two years, which suggests the newer products are rated better. We did not read a Growatt page on ProductReview.com.au for this guide.
For why star ratings alone do not settle the question, see our guide to the five-star problem.
Growatt recalls in Australia
Growatt has had two ACCC product recalls. In 2021, Growatt New Energy Australia recalled the 8.2 kW 8000 MTL-S inverter, made between 18 January and 26 February 2021, because the connectors were of mixed types and did not comply with electrical safety standards; SolarQuotes put the number at about 500 units. The remedy is a free on-site repair, and the serial number list was updated in 2025.
In late 2023 the ACCC announced a recall of SPH3000TL, 3600TL, 4000TL, 4600TL, 5000TL and 6000TL BL-UP hybrid inverters, where the backup (EPS) output connector was not fitted, leaving terminals exposed. SolarQuotes reported the problem in January 2024. Check any Growatt inverter you own on the ACCC Product Safety site and the Clean Energy Council recall list. We found no ACCC or Clean Energy Council recall of a Growatt battery.
Growatt vs alternatives
Growatt is cheaper to buy than the premium brands, but trails its main rivals on owner ratings and battery warranty. The table compares the Australian brands most often quoted against it.
| Growatt | Sungrow | GoodWe | Fox ESS | |
|---|---|---|---|---|
| SolarQuotes inverter rating | 4.4 (807) | 4.8 (5,483) | 4.8 (4,087) | 4.8 (233) |
| Battery capacity guarantee at year 10 | 50% | 70% | 70% | 70% |
| Battery usage limit | About 300 full cycles a year | Unlimited for self-consumption and backup | Throughput cap | Throughput cap |
| Battery works with other brands’ inverters | No (Growatt hybrids only) | Sungrow hybrids | GoodWe hybrids | Fox ESS hybrids |
| Our reviews | Growatt APX HV | Sungrow SBR | GoodWe Lynx | Fox ESS |
Choose Growatt if the quote is clearly lower than a like-for-like Sungrow, GoodWe or Fox ESS system, you already own a compatible Growatt inverter, and you will cycle the battery moderately. Choose a rival if you want a 70% capacity guarantee at year 10 or plan to use a virtual power plant (VPP) that cycles the battery hard; our VPP guide explains why throughput caps matter.
Where Growatt products are made and sold
Growatt is headquartered in Shenzhen and its Australian warranty card is issued by Growatt New Energy Technology Co., Ltd with Growatt New Energy Australia Pty Ltd as the local contact. SolarQuotes says much of Growatt’s production is in China, and that it shipped to Australia soon after it was founded, then left for some years and returned with a new inverter range. According to SolarQuotes, citing a Wood Mackenzie report, Growatt was the world’s fourth-largest inverter supplier in 2024, behind Huawei, Sungrow and Ginlong Solis; the report gave no figure for Growatt itself and we found no Australian share figure.
For Australian-made panels see our Australian-made solar panels guide.
Who installs Growatt?
Growatt is sold through distributors and installed by many Australian solar retailers, mostly volume installers competing on price. The installer matters more than usual with a budget brand, because it registers the warranty extension, sets up monitoring and escalates claims. Browse our installer directory or the top 10 installers, read our guides on how to compare solar quotes and how to choose an installer, and ask for the exact model suffix, warranty term and whether a Backup Box is included. Solar Cobber does not verify any installer’s accreditation; check the Clean Energy Council approved retailer list and the Solar Accreditation Australia register yourself.
FAQ
Who owns Growatt?
Growatt is a privately held Chinese company founded in 2011 and headquartered in Shenzhen, as far as we could confirm in November 2026. It filed a third Hong Kong listing application on 16 June 2026, and we found no evidence that it has listed. Growatt New Energy Australia Pty Ltd is its local entity.
Is Growatt a good brand?
Growatt is a budget brand with decent hardware and a mixed support record. SolarQuotes owners rate its inverters 4.4 out of 5 from 807 ratings, lower than Sungrow, GoodWe, Fronius and Fox ESS at 4.8, and its battery warranty is weaker than rivals.
Is Growatt a Chinese company?
Yes. Growatt was founded in 2011 and is headquartered in Shenzhen. SolarQuotes says much of its production is in China.
How long is the Growatt inverter warranty in Australia?
Five years as standard, extendable to 10 years by a free online registration, for 1.5 kW to 133 kW grid-connected and hybrid inverters. Growatt’s claim procedures state this, so ask your installer to register it for you.
How long is the Growatt battery warranty?
Ten years, but capacity is only guaranteed at 70% for years 1 to 5 and 50% for years 6 to 10, with a cap of about 300 full cycles a year. It drops to 3 years if the battery is not kept on Growatt monitoring.
Does Growatt have local support in Australia?
Yes. Growatt New Energy Australia lists 1800 476 928 and australia@ginverter.com for warranty claims, and SolarQuotes lists offices in Perth and Adelaide. SolarQuotes says Growatt’s Australian support still needs to improve.
