GoodWe inverters are a solid mid-range option for Australian homes, with strong hybrid models and competitive pricing.
GoodWe sits between budget options and premium European brands such as the Fronius Primo range. The model matters more than the badge: a solar-only MS and a battery-capable ET serve different households.
Our GoodWe inverter review covers the MS, ES, EH, ET and ESA product lines, their practical trade-offs and what to check in an Australian installation quote.
SolaXs installs GoodWe inverters across the Mid North Coast. We assess your roof, electricity use and battery plans before recommending a model.
GoodWe Inverter Range for Australian Homes
The MS, ES/EM, EH, ET and ESA families cover different rooftop and battery setups. Check the full model code and generation on your quote because specifications change within each family.
| Series | Type | Phase | Best For |
|---|---|---|---|
| MS | String (solar only) | Single | Standard rooftop systems with multiple orientations |
| ES / EM | Hybrid (low voltage battery) | Single | Adding a battery now or later with 48V batteries |
| EH | Hybrid (high voltage battery) | Single | Pairing with high-voltage batteries like BYD HVS/HVM battery options |
| ET | Hybrid (high voltage battery) | Three-phase | Larger homes with three-phase battery storage requirements |
| ESA | All-in-one hybrid + battery | Single or three-phase, depending on model | Integrated solar, battery and backup equipment |
The MS suits solar-only installations, while ES/EM models add low-voltage storage options. Three-phase homes considering batteries should compare the ET range with the appropriate ESA configuration.
About GoodWe
GoodWe (Jiangsu GoodWe Power Supply Technology Co., Ltd) is a Chinese inverter and battery storage manufacturer listed on the Shanghai Stock Exchange. The company operates an Australian office in Rowville, Victoria, which handles warranty claims, distributor relationships and local technical support.
GoodWe ships to over 100 countries and has an established distribution network in Australia. That matters when a replacement part or firmware update is needed years after installation. Ask the installer whether they deal directly with the Australian office or through a third-party distributor, because warranty service timelines can depend on that chain.
GoodWe MS Series Review
The MS is a single-phase solar-only string inverter. The MS G3 has three maximum power point trackers (MPPTs), according to GoodWe’s MS G3 specifications. That is useful for a roof with several panel orientations; it is not a feature unique to this brand.
Three MPPTs matter if your panels are split across multiple roof faces. Most single-phase inverters have two. That third tracker means a north-facing array, a west-facing array, and an east-facing array can each be optimised independently.
- Generation: these figures describe MS G3, not every MS inverter
- MPPTs: three independent trackers
- Input current: up to 20 A per MPPT
- Cooling: fanless natural convection
- Weight: 19 kg
- Source: Australian MS G3 datasheet
Panel capacity can exceed the inverter’s AC rating when the design stays within its voltage, current and input-power limits. More panels can increase morning and afternoon output, but the permitted array also depends on network approval and any incentive rules.
GoodWe Inverter Sizes
GoodWe inverter sizes depend on the series and generation. The MS G3 range spans 5 to 10 kW nominal output, with intermediate options listed in its Australian datasheet; confirm local approval and availability with your installer.
The MS G3 model table separates nominal AC output from maximum PV input power. A panel-system size is not the same as an inverter rating, so compare the two figures separately when reviewing SolaXs solar system packages.
GoodWe 8.5kW Inverter
The GW8500-MS-30 is an 8.5 kW single-phase, solar-only MS G3 inverter with three MPPTs. GoodWe’s datasheet lists 8,500 W nominal output and 13,175 W maximum input power; the latter is an equipment limit, not automatic permission to install that much solar.
It can suit a larger array spread across different roof faces. Ask the installer to check export limits, string design and daytime demand before choosing it over a smaller unit; battery charging would need separate compatible equipment.
GoodWe Hybrid Inverter Review
GoodWe’s hybrid range covers both low-voltage and high-voltage batteries. For home solar batteries, choose the inverter and battery together so the voltage, communication protocol and backup requirements match.
ES and EM Series (Low Voltage Hybrids)
ES and EM models use low-voltage battery systems. An existing owner should check their model’s compatibility list; a new buyer should also compare the ES G2 generation rather than treating ES and EM as interchangeable.
- Lynx Home U is a low-voltage option; our GoodWe battery review explains the battery range
- Lynx Home F is a high-voltage battery for compatible EH/ET models
- Backup output and changeover time depend on the exact inverter and installed wiring
- GoodWe’s battery compatibility list identifies supported combinations and firmware requirements
An inverter model alone does not establish eligibility for the federal solar battery rebate. The installed battery system and installation must meet the programme’s requirements, summarised in the FAQ below.
EH Series (High Voltage Hybrid)
The EH uses high-voltage batteries, including supported BYD Battery-Box HVS and HVM configurations and Lynx Home F combinations. GoodWe identifies Lynx Home F as an EH/ET-compatible high-voltage battery; check the module count and firmware for the particular inverter.
If you are comparing low-voltage (ES/EM) vs high-voltage (EH) hybrid setups, the right choice depends on your battery brand preference and system size. SolaXs can walk you through the trade-offs for your specific situation.
GoodWe ET for Three-Phase Homes
The ET range is the three-phase hybrid option in this comparison. GoodWe’s Australian product range includes ET G2 models from 6 to 15 kW, alongside other ET generations.
Ask for the backup rating per phase as well as total output. The battery’s discharge limit and the circuits wired for backup determine which appliances can run together during an outage.
- Check the exact ET generation against the battery compatibility list.
- List essential loads before the installer designs the backup circuits.
- Confirm whether large three-phase appliances are included in the backup design.
ESA All-in-One Hybrid
The ESA combines hybrid-inverter and LFP battery equipment in an integrated storage system. It suits homeowners who want a coordinated solar, storage and backup installation with fewer separately selected components.
- The single-phase ESA range spans 3–10 kW inverter output with modular battery storage
- GoodWe also lists a separate three-phase ESA range, so “ESA” alone is not a complete model specification
- Inverter power in kW and stored energy in kWh are different specifications
- Backup still depends on battery capacity, appliance demand and the installed circuit arrangement
Ask for the inverter code, battery modules and usable storage to be listed separately in the quote. A compact cabinet is helpful, but access clearances and the approved installation location still need to work at your home.
GoodWe Inverter Efficiency and Real-World Performance
Peak efficiency varies by MS G3 model: the Australian datasheet lists up to 97.9%. Manufacturer efficiency figures describe conversion under test conditions, not a promise about annual household generation.
A small difference in peak efficiency is rarely enough to decide between two inverters. Roof shading, string layout, export limits and installation temperature can have more practical influence on the system you end up with.
- Morning and evening performance: startup voltage matters, but an inverter also needs enough available panel power to generate useful output
- Heat management: keep the inverter shaded and allow the clearances in its manual. Derating depends on the model and operating conditions; there is no single temperature threshold for the whole brand. If the unit needs to be powered down for service, follow our guide on how to safely turn off your solar inverter before the electrician arrives
- Monitoring: ask to see SEMS alongside Fronius Solar.web and Sungrow’s iSolarCloud monitoring app before choosing. Our solar monitoring apps comparison covers the practical differences between platforms. The data available depends on the inverter and metering fitted.
Before buying, ask the installer to demonstrate SEMS and explain which readings require a consumption meter. Production data alone will not tell you how much solar the household uses.
GoodWe Inverter Price in Australia
A GoodWe inverter price needs an installation scope to be useful: buying the inverter, replacing an old unit and installing a complete rooftop system are different jobs. Request an itemised installed quote rather than treating an online hardware price as the final cost.
| Model or setup | What the price needs to include |
|---|---|
| MS string inverter | Exact output and generation, removal of the old unit if needed, electrical work and commissioning |
| ES/EM or ES G2 hybrid | Inverter, compatible low-voltage battery if selected, monitoring meter and backup wiring |
| EH hybrid or battery-ready model | Battery function activation where required, supported high-voltage battery and commissioning |
| ET three-phase hybrid | Three-phase metering, compatible battery and specified backup circuits |
| ESA integrated system | Inverter rating, number of battery modules, installation work and backup scope |
As an installed-system reference, SolaXs’ published Kew solar packages advertise a 6.6 kW panel system with a 5 kW GoodWe EH inverter from $4,850, subject to terms and conditions. Checked 10 September 2026: this is a whole-system starting price, not an inverter-only price or a battery-inclusive offer; confirm the specification and applicable discounts in your quote.
GoodWe Hybrid Inverter Price
The useful hybrid price is the total for the inverter plus the battery and backup functions you want to use. GoodWe’s EH product information lists battery-ready models, so ask what is needed to enable storage on the quoted model.
A cheaper battery-ready quote can become dearer once a meter, activation, switchboard changes and backup circuits are included. For a 6.6 kW solar panel package, confirm the inverter’s model code rather than assuming the panel rating also describes inverter output.
GoodWe Solar Inverter Price Comparison
Compare GoodWe, Fronius and Sungrow quotes using the same output, battery capacity and installation scope. Brand price labels alone cannot show whether one offer includes work that another leaves out.
- Compare prices including GST and identify any discounts separately.
- Check meter, monitoring connection and battery activation costs.
- Specify backup circuits and any switchboard or cabling work.
- Ask who handles warranty labour and site visits.
If replacing an older inverter is part of a battery plan, planning solar system upgrades can help you decide whether to retain the existing solar equipment or replace it together.
GoodWe Warranty and Australian Support
GoodWe warranty cover depends on the model and the conditions met at installation. The Australian warranty document (revision 5.8) distinguishes standard cover from promotions; “10 years full warranty on every model” is too broad.
| Model group | What to verify |
|---|---|
| MS and other eligible on-grid models | Ten-year promotion requires manufacture after 1 July 2020 and installation, registration and SEMS connection after 1 January 2021 |
| ES G2, ET G2 and listed newer ESA models | Listed with ten-year limited warranty |
| Older EH and ET 5–10 kW models | Promotion has specified Lynx Home F/F PLUS+ pairing, manufacturing date, SEMS upload and serial-registration conditions |
| Battery and accessories | Separate terms apply; the inverter warranty does not establish their coverage |
Keep the invoice, serial numbers and warranty certificate. Ask the installer to confirm labour and transport provisions in writing, including costs outside the manufacturer’s allowance.
For a claim, start with the installer or seller. If they cannot help, use GoodWe’s Australian warranty and support resources with the model details and fault information.
Common GoodWe Inverter Issues
If your GoodWe system develops a fault, these checks can help you decide what to do next.
- WiFi connectivity drops: the SEMS dongle can lose connection, especially on mesh WiFi networks. If your inverter stops reporting, see our GoodWe WiFi connection guide or the 10.10.100.253 setup page troubleshooting steps
- Heat derating on hot days: reduced output can be thermal protection, but repeated losses need investigation. The MS G3 uses fanless natural convection; cooling methods vary across other models
- Error codes on the display: if your GoodWe shows a fault code or red light, check our inverter beeping and red light troubleshooting guide before calling your installer
- Inverter not restarting after a grid outage: most GoodWe inverters restart automatically, but sometimes a manual reset is needed. Follow our GoodWe inverter reset guide for step-by-step instructions, or see how to turn on a solar inverter if the unit was switched off at the isolator
A monitoring outage does not necessarily mean the inverter has stopped generating. Check whether your solar inverter is producing power before treating a blank app reading as an equipment failure.
GoodWe MS G3 AC Plug Recall
GoodWe’s MS G3 recall notice identifies an AC plug on affected units that can expose live terminals if removed. Owners should not touch or remove the plug; ask the recall team to check whether the unit needs rectification.
The notice covers affected MS G3 equipment, not all GoodWe inverters, and describes free rectification. For other persistent faults, SolaXs can arrange solar maintenance and repairs so an electrician can investigate the cause.
Who Should Choose a GoodWe Inverter
GoodWe is worth shortlisting if you want a choice of solar-only and hybrid models at different budgets. Battery readiness is useful when the specific inverter supports the battery you are likely to buy.
- Good fit: homeowners wanting a hybrid inverter with battery compatibility at a lower price than Fronius or SMA
- Good fit: systems with panels on three or more roof orientations (MS G3 with three MPPTs can suit this layout)
- Good fit: households planning a battery supported by the quoted hybrid model
- Less ideal: homeowners who prioritise having the best monitoring app experience
- Less ideal: installations in extremely hot, unshaded west-facing locations where sustained heat derating is a concern
For solar installation in Port Macquarie, the inverter location deserves as much attention as the brand. Salt exposure, shade and ventilation should be checked on site; an ingress rating alone does not establish suitability for every coastal position.
GoodWe vs Fronius vs Sungrow: Quick Comparison
Most homeowners shortlist two or three inverter brands before deciding. Start with comparable models, then use the GoodWe vs Fronius inverter comparison to weigh the features relevant to your roof.
| Feature | GoodWe | Fronius | Sungrow |
|---|---|---|---|
| Price point | Mid-range | Premium | Mid-range |
| Hybrid options | ES, EH, ET and ESA families | GEN24 Plus range | SH range |
| MPPTs (single-phase) | 3 on MS G3; other models vary | Check the quoted model | Check the quoted model |
| Monitoring app | SEMS; confirm meter requirements | Solar.web; ask for a demonstration | iSolarCloud; ask for a demonstration |
| Warranty | Model and promotion conditions apply | Check Australian terms and registration | Check Australian model terms |
| Cooling | MS G3 fanless; other models vary | GEN24 uses active fan cooling | Check the quoted model |
| Made in | China | Austria | China |
GoodWe MS G3 is worth comparing for roofs that benefit from three trackers. Fronius confirms that GEN24 uses active cooling. MS G3 uses fanless cooling.
Monitoring preferences are personal: ask to see each app with a working system. The Sungrow vs Fronius comparison covers those two alternatives in more detail.
Our Recommendation by Situation
Start with the roof layout and supply phase, then compare the battery and monitoring options you will use.
- For complex roofs: GoodWe MS G3 (three MPPTs handle north, east, and west-facing arrays independently)
- For a battery-ready quote: GoodWe ES or EH (confirm battery compatibility and any activation costs)
- For monitoring: ask for a demonstration of Fronius Solar.web alongside SEMS
- Alternative hybrid shortlist: the Sungrow SH hybrid range, compared on installed price, battery support and monitoring
- For three-phase homes: compare GoodWe ET with other three-phase solar inverter options using backup output per phase
A site assessment should consider roof layout, energy use and future plans. SolaXs provides residential solar installation with system design based on those requirements.
Choosing the Right Inverter for Mid North Coast Conditions
Humidity, salt air near the coast and summer storms all affect where an inverter should be installed. Shading and roof orientation also influence expected output, so a suburb-wide sunshine average cannot predict one household’s generation.
- Enclosure and location: check the model’s ingress rating and installation manual, including any limits on coastal exposure
- Surge protection: ask the electrician what protection is included and whether additional protection is needed. It cannot guarantee immunity from lightning; solar inverter replacement costs depend on the damage and replacement scope
- Monitoring app quality: a good monitoring app lets you spot production drops early. Check that the app works reliably on both iOS and Android before committing
The assessment should identify a suitable mounting location before a model is recommended. Keep the space around the inverter accessible for service and clear of stored household items.
GoodWe Inverter FAQ
- Buying: compare the exact model, installed scope and warranty.
- Adding storage: check battery compatibility and backup requirements.
- Existing owners: distinguish monitoring faults from generation faults.
Are GoodWe inverters any good?
GoodWe is a reasonable shortlist for Australian homes, especially when the MS tracker layout or a compatible hybrid suits the design. Judge the quoted model’s features, warranty conditions and installer support; a brand-wide reliability claim cannot predict an individual unit’s life.
How long do GoodWe inverters last?
A warranty period is not a lifespan forecast. Heat exposure, installation quality and operating conditions affect service life; keep monitoring active and have persistent faults checked rather than assuming the inverter will run for a fixed number of years.
How much does a GoodWe inverter cost?
Ask for an itemised installed price for the exact model. The pricing section above separates inverter replacement, battery-ready equipment and complete-system offers, because mixing those scopes can make a cheap quote look more comprehensive than it is.
What is the GoodWe SEMS app?
SEMS is GoodWe’s monitoring portal and app. It can report generation and, with the appropriate equipment, battery operation and household consumption.
Internet access uses the communication hardware fitted to the model, which may support Wi-Fi, LAN or optional mobile data. An app connection failure does not by itself prove a generation fault.
Can I add a battery to a GoodWe inverter later?
A compatible hybrid can support a later battery, subject to activation and the supported battery list. An MS cannot connect a battery directly, but a separately designed AC-coupled battery system may let you retain the MS.
Check those options before replacing a working solar-only inverter. Buying “battery ready” equipment now does not guarantee compatibility with every battery sold later.
What batteries work with GoodWe inverters?
ES/EM low-voltage models and EH/ET high-voltage models require different batteries. GoodWe’s compatibility overview lists approved pairings, module counts and firmware conditions; Lynx Home U is low voltage and Lynx Home F is high voltage.
Never assume that a matching voltage or another brand’s battery is sufficient. Ask the installer to confirm the complete inverter-and-battery combination in writing.
Do GoodWe hybrid inverters qualify for the battery rebate?
The inverter alone does not attract the battery discount. Under the Clean Energy Regulator’s battery rules, eligibility attaches to an eligible solar battery installation, including approved equipment and a Solar Accreditation Australia (SAA) accredited installer with battery endorsement.
Last checked 10 September 2026: the May to December STC factor is 6.8 before capacity tapering, with lower support for capacity above 14 kWh. Have the installer calculate the discount for the installation date; a fixed dollar-per-kWh rebate is not a reliable quote.
How does GoodWe compare to Fronius?
Compare a particular GoodWe model with the equivalent Fronius model and installed scope. MS G3 offers three trackers and fanless cooling; GEN24 uses a fan, and its monitoring and backup options need to be compared with the chosen GoodWe system.
Is the GoodWe warranty really 10 years?
Ten-year cover is available for listed models or through qualifying promotions, but it is not unconditional across the range. Check the written warranty and certificate for your model, battery pairing and registration rather than relying on a generic sales claim.
How do I read the display on my GoodWe inverter?
Display layouts differ by generation, and some models rely on LEDs and app readings. Understanding your GoodWe inverter display helps you distinguish production readings from status and fault messages.
What size GoodWe inverter do I need?
Start with daytime demand, the proposed panel array, supply phase and network limits. A larger inverter does not automatically deliver more useful power; the solar system sizing guide explains how household demand shapes the design.
Where is GoodWe based?
GoodWe is based in China and provides Australian warranty and support resources. Keep your installer’s contact details with the commissioning documents so a fault can be raised with the people who supplied the system.
