Growatt Inverter Review 2026: MIN, MOD and SPH Specs and Verdict

Growatt is a Shenzhen-based inverter maker whose hybrid inverters appear on many low-priced Australian quotes, usually sold together with a Growatt APX battery. This review covers the single-phase MIN TL-XH2 (2.5 to 6 kW), the three-phase MOD hybrids (3 to 15 kW), the larger MID XH (10 to 30 kW) and the single-phase SPH and SPA lines (3.6 to 6 kW). It is based on manufacturer documentation, warranty terms, published pricing and owner and installer feedback; Solar Cobber did not test the product and was not paid by the manufacturer.

What it is and how it works

A hybrid inverter converts solar DC power to AC for the home and also charges and discharges a battery, so one box does both jobs. Growatt’s current Australian hybrids are the MIN TL-XH2 (single phase), the MOD TL3-HU and TL3-XH (three phase) and the MID TL3-XH (larger three phase). Our guide to what a hybrid inverter is explains the idea, and best hybrid inverters in Australia shows where Growatt sits.

Growatt also sells the older SPH and SPA single-phase units, which pair with its low-voltage ALP battery, and string-only MIN X2 inverters of 7 to 10 kW. Each hybrid family works with a specific Growatt battery, covered in our Growatt battery review. In market terms, Growatt is a value-tier brand alongside GoodWe and Solis, with a brand guide here.

Specs that matter in Australia

Growatt states these figures on its Australian datasheets (the MIN XH2 and MOD XH undated, the MOD HU dated July 2026).

Sizing the solar array. The MIN XH2 accepts a lot of panels for its size: 5 kW of AC output pairs with up to 11.6 kW of panels, a ratio of about 2.3 to 1. That helps homes with panels on several roof faces, but the network still limits how much you can export.

The chart shows Growatt’s stated maximum PV for each MIN XH2 size. Even the 2.5 kW unit takes 5 kW of panels, and every model allows roughly double its AC rating or more.

The MIN XH2 allows about twice its AC rating in panels, and the 5 kW model is the most generous at 11.6 kW.

Efficiency. Growatt’s figures are close to its main rivals. The chart compares maximum and European (weighted) efficiency from Growatt datasheets and from our SolaX inverter review.

Growatt’s three-phase hybrids list 98.3 to 98.6% maximum efficiency, about half a point above the SolaX X1 G4. Differences of a few tenths of a percent change annual output very little.

Heat. The MOD HU datasheet allows -25 to +60 C but derates above 45 C, and the MIN XH2 allows -30 to +60 C. Mount any inverter in shade, as our guide on string inverters and MPPTs explains.

Backup. The MOD HU has integrated backup output of 5 to 9 kW nominal, according to Growatt’s brochure and datasheet. The single-phase MIN XH2 datasheet states that backup “need[s] a Backup Box accessory”, and the MID XH needs a SYN100-XH-30 device, so confirm in writing that blackout power is in your price. Most homes are single phase; see single or three phase power.

VPPs. Growatt says its batteries work with Evergen for the NSW incentive. Confirm any virtual power plant offer with the retailer before relying on the income.

Clean Energy Council listing: the dates that matter

The Clean Energy Council (CEC) approved inverter list is the register installers use for the small-scale scheme, and an inverter must be listed when it is installed. We queried the CEC inverter list’s own data on 14 November 2026 and found 53 Growatt inverter entries, with these expiry dates.

The chart turns those dates into days remaining. This is a Solar Cobber calculation: days between 14 November 2026 and each CEC expiry date.

The older MOD XH three-phase listing has about 68 days left, so it expires in January 2027. We could not find the newer MOD 5-15KTL3-HU in the CEC data when we searched on 14 November 2026, although Growatt publishes a July 2026 datasheet for it. Listings can change quickly, so ask your installer for the exact model number and its listing before you sign, and check the CEC list yourself.

Price in Australia

Growatt does not publish retail prices, and we found no dated 2026 inverter-only price list that states whether GST is included. The only recent range we could verify comes from owners. SolarQuotes says its reviewers report paying A$4,500 to A$12,500 for a complete 5 to 10 kW system with a Growatt inverter, depending on hardware and installation difficulty (page checked 14 November 2026). The same page notes that cheap Growatts can attract bottom-end installers.

Batteries drive the price of a hybrid package. One installer, Austar Solar, published installed APX HV battery prices of A$7,500 to A$8,500 for 10 kWh in October 2026, before the federal discount; see our battery review and how the battery rebate works. For string-inverter pricing see our solar inverter price guide.

Warranty: the fine print

The warranty is the confusing part. Growatt’s Australian datasheets for the MIN XH2, MOD XH, MOD HU and MID XH all list a 10-year warranty. The Growatt Factory Warranty card (February 2026 issue), which covers the MIN, MOD, MID, SPH and SPA models, does not state a base term in the text we could read. It says a paid extension to 15 or 20 years is possible only within 2 years of delivery from Growatt, and it refers to “the years beyond 5”, which suggests a 5-year base term. SolarQuotes also describes a 5-year standard warranty extendable by 5 years to 10 on selected models.

Our reading is that the 10-year term may depend on registration or an extension, but we could not confirm this. Ask your installer for the term for your exact model in writing, and the warranty check page at au.growatt.com/support/warranty will show the recorded period for a serial number.

The chart compares headline terms with the rivals in our own reviews. Growatt’s base term is left blank because we could not confirm it.

Other terms to check on the Growatt card:

• Validity: the warranty starts at installation if that is within six months of delivery, otherwise six months after delivery. It is non-transferable.
• After year 5: Growatt decides how to carry out the remaining warranty and is not responsible for logistics or labour costs in that period.
• Exclusions: opening the casing, transport damage, incorrect installation, unauthorised repairs and insufficient ventilation.
• Claims: report a defect to your supplier within 14 days of the first signs, with the invoice and commissioning report.
• Local contact: Growatt New Energy Australia Pty Ltd, Unit 4 and 5, 378 Parramatta Rd, Homebush West NSW, phone 1800 476 928.

The card states that Australian Consumer Law guarantees apply. Growatt has had one past Australian recall, of the 8 kW 8000MTL-S string inverter in 2021, according to SolarQuotes. See also inverter repair and replacement costs.

What owners and installers report

SolarQuotes shows 807 owner ratings of Growatt inverters averaging 4.4 out of 5 (checked 14 November 2026). The most recent review at that check was dated 12 March 2026.

Almost two in three ratings are five stars, but 45 ratings (5.6%) are one star. The distribution is polarised, which fits the complaints below.

Recurring patterns on that page:

• Support. Several one-star owners describe long waits for repairs or help, from two months to nearly two years. Others, including a December 2025 reviewer, say Growatt Australia “have been a real help”.
• Commissioning. SolarQuotes lists tricky commissioning as a con, so installer skill matters more than with some brands.
• App and display. One four-star owner reported the app occasionally stopping and the display being hard to read in morning sun.
• Warranty experience. One owner reported a free replacement after almost six years under a 10-year warranty; another said their installer would not honour the warranty without manufacturer authority.

SolarQuotes founder Finn Peacock says the first Growatt inverters were not good and newer models are better, and Growatt is not on SolarQuotes’ recommended inverter brands chart.

Growatt hybrids vs alternatives

The table compares the Growatt MIN and MOD hybrids with the other hybrids in our reviews. Prices are those quoted in each review for the inverter alone, not Growatt-specific.

Choose a Growatt hybrid if price matters most and your installer has a good record with the brand. The Sungrow SH RS and SolaX cost similar amounts with a firm 10-year term, and the GoodWe has a large installer base. Whichever you choose, use our guide to comparing solar quotes.

Questions to ask your installer

• Which exact Growatt model is quoted, and is it on the CEC inverter list today with an expiry date after my install?
• What warranty term applies to my inverter, can I have it in writing, and does it need registration on Growatt’s server?
• Is a Backup Box (MIN) or backup device (MID) included, and which circuits does it back up?
• Who commissions the system, and will I get my own ShinePhone owner login at handover?
• Which battery is quoted, and is the quoted combination listed as compatible by Growatt?
• If you stop trading, who honours the installation and the inverter warranty?
• How many panels, and what export limit, will you set for my network?

FAQ

Is Growatt a good inverter brand?

It is a low-cost brand with good specifications and high owner ratings (4.4 out of 5 from 807 SolarQuotes ratings), but the installer and Australian support matter a lot. SolarQuotes lists lacklustre support and tricky commissioning as cons.

How long is the Growatt inverter warranty in Australia?

Growatt’s Australian datasheets say 10 years, but its warranty card does not state the base term and SolarQuotes describes 5 years standard, extendable to 10. Ask for your model’s term in writing.

Are Growatt inverters on the Clean Energy Council list?

Many are: 53 Growatt inverter entries were listed on 14 November 2026, including MIN XH2 to 10 July 2027. We could not find the MOD 5-15KTL3-HU, and the MOD XH listing expires on 21 January 2027, so check your model.

Do Growatt hybrid inverters work with other batteries?

In practice no. Growatt’s datasheets list its own APX and ALP batteries, and its battery warranty excludes non-Growatt inverters, so a hybrid quote normally means a Growatt battery.

What is the difference between Growatt MIN and MOD inverters?

MIN is single phase (2.5 to 6 kW hybrid) and MOD is three phase (3 to 15 kW hybrid). MOD HU has integrated backup while the MIN XH2 needs a Backup Box.

Does a Growatt inverter work in a blackout?

Only with backup hardware: the MOD HU has it built in, but the MIN XH2 needs a Backup Box and the MID XH needs a SYN100-XH-30 device. Confirm in writing that backup is included.
