Inverter comparison
Best solar inverters for Melbourne homes in 2026: twelve brands compared
There is no single best solar inverter for a Melbourne home. The right one depends on your supply (the five networks serving Melbourne pre-approve up to 10 kW of inverter on a single phase home and 30 kW on three phase), whether you want a battery now or later, shade on your roof, and the warranty and local support behind it. We compare fourteen inverter ranges from twelve makers sold in Australia, from each maker’s own documents, checked 26 October 2026 to 5 November 2026.
Warranties run from 5 to 25 years, and twelve of the fourteen ranges are hybrids or battery-ready. The table lists brands alphabetically: it is not a ranking. Which brands we install is being confirmed; your quote names the exact model.

How we compared them
A list of the top 10 solar inverter manufacturers is only as useful as what it measures. We started from the inverter brands Australians search for most by name in our keyword research (August 2026) and compare twelve of them: Alpha ESS, Enphase, Fox ESS, Fronius, GoodWe, Growatt, Sigenergy, SMA, SolarEdge, SolaX, Solis and Sungrow. Each row is one range of home inverters, with figures from the maker’s own Australian datasheets, product pages and warranty documents. Where a maker doesn’t state a figure, the table says so.
We are an installer, not a test lab. Our previous website listed Sungrow, Fronius and Alpha ESS inverters; the brands we install today are being confirmed, so no row is marked as ours. No maker paid to be included, and the order is alphabetical. We compare phase and sizes, the panel power each model takes (its DC oversizing limit), MPP trackers, batteries, blackout backup, the warranty and the Australian office.
Hybrid and string inverters compared
Each row links the documents its figures come from. A hybrid runs panels and a battery from one box; a string inverter runs panels only; a battery-ready inverter takes the maker’s battery later but has no backup; and microinverters sit behind each panel.

SMA Australia says it will no longer sell the Sunny Boy Smart Energy, and its Australian product pages list no other home inverter. It stays here because the name still comes up, and installed units keep their warranty.
For most makers this version compares a single phase range; three phase homes are covered under which inverter suits which home. Specifications change: your quote names the exact model, its datasheet and its warranty.
A few links open the maker’s own file as hosted by a distributor or retailer (Plico, SolarProof and SolarQuotes); each link’s full name says so.
Which inverter suits which home
These groups come straight from the table, and a range can be in several. We leave out SMA Sunny Boy Smart Energy, which is no longer sold.
You want a battery now or later
Choose a hybrid or battery-ready inverter, and check it runs the battery you want. Each maker lists the batteries its inverter works with:
- Alpha ESS SMILE-G3-S5: Alpha ESS SMILE-G3 9.3 kWh modules, 1 to 4 in series (up to 37.2 kWh).
- Fox ESS KH: Fox ESS high-voltage batteries (85 to 480 V battery input).
- Fronius Primo GEN24 and Symo GEN24: Fronius Reserva, BYD Battery-Box Premium HVS/HVM and LG RESU FLEX, per Fronius.
- GoodWe EHB: GoodWe LX F and LX F G2 (Lynx Home F), BYD HVS and HVM, and LG RESU 10H Type R and Prime (80 to 495 V).
- Growatt MIN TL-XH2: Growatt APX HV battery, now or added later.
- Sigenergy SigenStor Energy Controller: Sigenergy’s own SigenStor BAT modules, 1 to 6 stacked on each controller.
- SolarEdge Home Hub: SolarEdge Home Battery (up to 3), or LG RESU10H Prime or RESU16H Prime (up to 2).
- SolaX X1-Hybrid G4: Lithium or lead-acid, 80 to 480 V; SolaX pairs it with its own T30 battery.
- Solis S6-EH1P L-PLUS: Low-voltage (40 to 60 V) lithium or lead-acid batteries on Solis’s approved list.
- Sungrow SH-RS: Sungrow high-voltage batteries (80 to 460 V input).
- Sungrow SH-T three phase: Sungrow high-voltage batteries (100 to 700 V input on SH15T to SH25T).
A hybrid also runs solar on its own until the battery goes in. Choosing the battery first narrows the inverter choice: our battery comparison sets out the batteries side by side.
Solar only, or a like-for-like replacement
For panels without a battery, the options here are Enphase IQ8 microinverters and Fronius Primo. A string inverter has no battery connection, so a battery added later comes with its own inverter (AC coupling).
Shade, or panels on several roof faces
Enphase IQ8 microinverters and SolarEdge Home Hub work panel by panel, so one shaded panel doesn’t pull the others down. With a string or hybrid inverter, more trackers let each roof face run as its own string: Fox ESS KH (up to 4), GoodWe EHB (up to 4), Sigenergy SigenStor Energy Controller (up to 4), Sungrow SH-RS (up to 4) and Sungrow SH-T three phase (up to 3).
Microinverters vs string inverters
Keeping the power on in a blackout
Backup needs the right inverter, usually a battery, and wiring for the circuits you want kept on. The table’s “Blackout backup” column gives what each maker states, including any extra gateway or backup unit it needs. Fox ESS KH, GoodWe EHB, Sigenergy SigenStor Energy Controller, SolaX X1-Hybrid G4, Solis S6-EH1P L-PLUS, Sungrow SH-RS and Sungrow SH-T three phase quote a switch to backup within 10 ms, so lights and computers barely notice.
Blackout protection with a battery
Three phase homes
A three phase inverter spreads its output across all three phases, which is how larger systems fit within your network’s limits. In this table, these suit three phase supply:
- Enphase IQ8 microinverters: Single or three phase (multi-phase cabling spreads the microinverters across all three), 360 W (IQ8AC) or 380 W (IQ8HC) per panel; the system size is set by the number of panels.
- Fronius Primo GEN24 and Symo GEN24: Single phase (Primo GEN24) or three phase (Symo GEN24), Primo GEN24 3 to 10 kW; Symo GEN24 3 to 12 kW.
- Sigenergy SigenStor Energy Controller: Single phase (SP) or three phase (TP), 5, 6, 8, 10 and 12 kW single phase; 5 to 30 kW three phase.
- Sungrow SH-T three phase: Three phase, 5 to 25 kW (SH5T to SH25T).
Other makers here also sell three phase models we haven’t compared yet, such as GoodWe’s ESA, Fox ESS’s H3 Smart and H3 Pro and Growatt’s MOD-XH. Single or three phase? Here’s how to tell.
Adding a battery to solar you already have
Keep your inverter and add a battery with its own inverter (such as the Enphase IQ Battery 5P with FlexPhase), or swap to a hybrid: adding a battery to existing solar.
GoodWe vs Sungrow: two single phase hybrids side by side
GoodWe and Sungrow are two of the inverter brands Australians search for most, and “GoodWe vs Sungrow” is a common question. Here are their single phase hybrids, from each maker’s own documents. Our previous website listed Sungrow, not GoodWe.
| Feature | GoodWe EHB | Sungrow SH-RS |
|---|---|---|
| Sizes | 5, 8.6 and 9.99 kW (GW5K to GW9.99K-EHB) | 5, 6, 8 and 10 kW (SH5.0RS to SH10RS) |
| Panels it takes | Up to 200%: 10 kWp on the 5 kW model, 17.2 kWp on the 8.6 kW and 20 kWp on the 9.99 kW | Up to 12 kWp (SH5.0RS) and 13 kWp (SH6.0RS); up to 200% on SH8.0RS and SH10RS |
| MPP trackers | 3 (5 kW) or 4 (8.6 and 9.99 kW) | 2 (5 and 6 kW) or 4 (8 and 10 kW) |
| Batteries | GoodWe LX F and LX F G2 (Lynx Home F), BYD HVS and HVM, and LG RESU 10H Type R and Prime (80 to 495 V) | Sungrow high-voltage batteries (80 to 460 V input) |
| Blackout backup | Switches to backup in under 10 ms, with backup output up to its rating and a built-in bypass | Switches to backup in under 10 ms; SH8.0RS and SH10RS have a 63 A bypass for whole-home backup |
| Rating | IP65 | IP65 |
| Warranty | 10 years from installation (or from 12 months after manufacture, if that is earlier) | 10 years from installation in Australia (at most 11 years from manufacture) |
| Monitoring | SEMS portal | iSolarCloud |
| Australian office | Rowville, VIC | North Sydney, NSW (hotline 1800 786 476) |
The clearest difference is the battery: the GoodWe EHB also lists BYD and LG batteries, which helps if you have or want one, while Sungrow’s hybrid is built around Sungrow’s own. Both warrant the inverter for 10 years, with different start rules. The size steps differ too, so choose on fit, not brand.
Warranties and local support
The maker’s warranty covers defects in the inverter itself. The term is only part of it: check when it starts, what you must do to keep it (buying through an authorised seller, claiming within a set time) and who handles a claim, usually your installer first. The Australian Consumer Law’s guarantees apply on top of any maker’s warranty.

| SolaX Warranty: SolaX warranty terms V1.6, Australia | 10 years from installation (at most 129 months from manufacture) | Bought from an authorised reseller, fitted by a SolaX-certified installer; claims through the distributor or installer within one month of the failure. | Dandenong South, VIC |
| Solis Warranty: Solis warranty terms, Australia and New Zealand | 5 years standard (the extra 5 years in Solis’s terms is for string inverters); paid extensions to 10, 15 or 20 years | Registered on SolisCloud and kept online; tell Solis Australasia within 30 days of the defect. Its service page headlines 10 years for inverters under 110 kW, so ask which term applies. | Cheltenham, VIC |
| Sungrow Warranty: Sungrow inverters 10-year limited warranty, copy hosted by SolarProof | 10 years from installation in Australia (at most 11 years from manufacture) | See the maker’s warranty document | North Sydney, NSW (hotline 1800 786 476) |
A long term only helps if the maker is around to honour it, which is why the table shows where each maker’s Australian office is. Register the inverter with the maker when it is installed, and keep your invoice.
Your quote sets out our workmanship warranty on the installation, alongside the maker’s inverter warranty.
What the datasheet figures mean
The inverter types and the panel-to-inverter ratio are on our solar inverters page, with what size inverter you need. Two columns need a word more.
MPP trackers
A maximum power point tracker keeps a string of panels at its most productive voltage as the sun and shade change. Panels facing different ways, or shaded at different times, belong on separate trackers. The ranges here have 2 to 4, while Enphase IQ8 microinverters and SolarEdge Home Hub track every panel.
Backup output and IP rating
The backup output sets how much can run at once, and a bypass lets the whole home run through the inverter rather than a few circuits. Every range here that states an IP rating (how well the case keeps out dust and water) is IP65 or higher, rated by its maker for outdoor use.
The inverters we install
Our previous website listed Sungrow, Fronius and Alpha ESS inverters. The brands we install today are being confirmed, so this comparison doesn’t mark any of them as ours. After a free inspection, your quote names the exact model, its size and its warranty, and why it suits your home.
More on the brands our previous website listed:
- Sungrow inverters: the SH-RS and SH-T hybrids.
- Fronius inverters: the Primo and GEN24 ranges.
- Alpha ESS batteries: the SMILE-G3 inverter and battery system.
Comparing inverters: your questions
Which solar inverter brand is best in Australia?
None is best for every home. Choose on fit: the right phase and size for your network, a hybrid if you want a battery now or later, panel-level electronics for a shaded roof, then the warranty and the maker’s Australian support. We compare twelve brands sold in Australia on those points, from their own documents, and list them alphabetically rather than ranking them. Which inverter suits which home
GoodWe or Sungrow: which hybrid inverter should I choose?
They are close on paper: both are single phase hybrids with 10-year warranties, in a similar range of sizes. The bigger difference is the battery. The EHB takes GoodWe LX F and LX F G2 (Lynx Home F), BYD HVS and HVM, and LG RESU 10H Type R and Prime (80 to 495 V); the SH-RS takes Sungrow high-voltage batteries (80 to 460 V input). GoodWe’s Australian office is in Rowville, VIC, Sungrow’s in North Sydney, NSW. Choose the battery you want first, then the inverter that runs it. GoodWe vs Sungrow side by side
Which solar inverter has the longest warranty?
Of the fourteen ranges we compared, the longest term belongs to the Enphase IQ8 microinverters: 25 years from activation (IQ8 microinverters activated on or after 30 September 2025). Seven ranges carry 10 years, and the shortest stated term is 5 years (Fronius, SMA and Solis). Growatt states no standard term on the warranty card we read. Terms start at installation or activation, and some need the product bought through an authorised seller, so read the conditions. Warranties and local support
What does DC oversizing mean on an inverter datasheet?
It is how much panel power an inverter accepts compared with its own rating. Without a battery, the SAA Technical Requirements (version 1.9, February 2026) require the inverter’s output to be at least 75% of the panels’ peak power. With a battery connected, the panels can go beyond that, but never past the maker’s own maximum. That maximum is the “Panels it takes” column in our table, and it differs a lot between brands. Compare the panels each takes
How many MPP trackers does a solar inverter need?
One for each group of panels that faces the same way and gets the same shade, so each string runs at its own best voltage. Panels on two roof faces need at least two. The string and hybrid models here have 2 to 4 trackers. Enphase IQ8 microinverters and SolarEdge Home Hub track every panel on its own, which helps most on a shaded or split roof. What the datasheet figures mean
Why does an inverter brand’s Australian office matter?
A warranty claim usually starts with your installer, but if the installer has closed you deal with the maker, so local support makes a difference. Of the twelve makers here, Enphase, Fox ESS, Fronius, GoodWe, SolaX and Solis name an office in Victoria; Alpha ESS, Growatt, Sigenergy, SMA and Sungrow in New South Wales; and SolarEdge gives an Australian support line. The guarantees under Australian Consumer Law apply on top of any maker’s warranty. Each maker’s office and terms
Does SMA still sell inverters in Australia?
SMA Australia says it will no longer sell the Sunny Boy Smart Energy, and its Australian product pages list no other home inverter (checked 2 November 2026). Installed SMA inverters keep the factory warranty they were sold with; SMA’s current terms give 5 years in Australia on purchases after 20 May 2026 (SMA’s registration extension to 10 years is not offered here). SMA Australia still lists an office in North Sydney, NSW and an online service centre for help with installed systems. Other inverters to replace it with
Can a solar inverter keep the power on in a blackout without a battery?
Usually not: a grid-connected inverter shuts off when the grid goes down, so line workers are safe. Some can still run something from the panels alone, such as the Fronius Primo GEN24 and Symo GEN24 (PV Point: up to 3 kVA from the panels during a blackout). That power comes and goes with the sun. For evenings and cloudy days you need a battery and a backup circuit. Blackout backup with a battery
Choosing an inverter brand for a Melbourne home
In Melbourne, Victoria’s grid rules narrow the table before any brand does. Since 1 October 2024, a new or replacement system here has needed a compatible (CSIP-AUS certified) inverter on the CEC approved list and a reliable internet connection for the emergency backstop; without internet, a lower export limit applies. So the exact model on your quote must qualify, and it should stay online, which counts twice with Enphase, Sigenergy and Solis: their warranties depend on it too. If a claim goes past your installer, Enphase (South Melbourne), Fox ESS (Springvale), Fronius (Tullamarine), GoodWe (Rowville), SolaX (Dandenong South) and Solis (Cheltenham) name an office in Victoria. We check your supply and switchboard, then quote the model that fits.
