Overview of GoodWe – Company History
Jiangsu GoodWe Power Supply Technology Co Ltd was founded in 2010 in Suzhou, China. In 2012, GoodWe established itself in the Australian market, setting up an office in Melbourne. GoodWe designs and manufactures inverters for the residential, commercial, and energy storage markets. GoodWe manufactures inverter sizes ranging from 0.7kW to 250kW of both single and three-phase types.
GoodWe quickly grew to be an internationally renowned inverter manufacturer, with more than 1200 employees situated in 15 different countries. By the end of 2019, GoodWe had distributed inverters to more than 100 countries totalling a global PV installation of 15GW.
GoodWe in 2019 was considered the largest storage hybrid inverter supplier, and a top 5 single-phase string inverter supplier worldwide by Global energy research consultancy group Wood Mackenzie. In 2020, EUPD Research awarded GoodWe the Top Brand PV seal in Australia for the second consecutive year. In February 2020, GoodWe became the world’s first non-European inverter manufacturer to obtain the prestigious VDE-AR-N 4110-2018 compliance certificate by TÜV Rheinland Industrie Service. Also in September 2020, GoodWe was listed on the Shanghai Stock Exchange.
Following a scrutinous selection process, GoodWe has been awarded an exclusive licensing contract for global sales by General Electric (GE).
A Brief Rundown on Solar Inverters
A solar system’s inverter is the point at which the DC electricity produced by solar panels is turned into grid-compatible AC electricity. Typically there are 2 approaches to inverters – either string inverters or micro-inverters
String inverters (such as most of GoodWe’s product range) have traditionally been the standard in the solar industry. They send the power produced by solar panels to a central inverter that changes it from DC electricity to the usable AC electricity that powers homes. Goodwe also specialises in hybrid string inverters which provide the ability to charge a battery as well as use solar power immediately as its created.
Micro-inverters, generally a more expensive solution, provide a small inverter for each solar panel that is installed. This means that each panel operates individually which creates more visibility over performance and can offer some advantages in partly shaded conditions.
GoodWe Inverters – Points of Difference
Range of Hybrid Inverter Options
GoodWe has the largest range of storage inverters on the market including single-phase LV hybrid solutions (ES, EM), single-phase AC coupled retrofit solutions (SBP), single-phase HV hybrid (EH) and three-phase HV hybrids (ET). This makes GoodWe a good option if you are installing a battery that requires a hybrid inverter or if you plan to keep your options open to installing batteries in the future.
Multiple MPP Trackers
Maximum Power Point Trackers (MPPTs) dictate how many different roof orientations a string inverter can handle. If panels on the same MPPT are tilted differently they will only perform as well as the lower-performing panel which will impact output throughout the day. GoodWe’s inverters are often selected as they offer more MPPTs than their competitors across different inverter sizes. GoodWe’s MS series is the only 3 MPPT single-phase inverter in the Australian market. This means if, for example, you were hoping to install panels on the North, West and East sides of your house, your options would be to use a GoodWe MS or use a more expensive micro-inverter or power optimiser solution.
DC Oversizing
DC oversizing refers to installing more solar panel capacity than the output potential of the inverter. At face value, this seems like a design like this could be wasting some power, but after factoring in efficiency losses and acknowledging that solar panels will never output their nameplate watt rating, oversizing by 33% can be a cost-effective design and is permitted by the Clean Energy Council’s guidelines. Oversizing beyond 33% can be advantageous if you have a battery installed and can store surplus DC energy.
Goodwe’s Inverter Range
The XS Series is GoodWe’s smallest available inverter about the size of an A4 piece of paper and only weighs 5.2kg. It’s a Single-Phase string inverter with 1 MPPT available in sizes ranging from 0.7-3kW. It offers 33% DC oversizing and up to a max efficiency of 97.6%. | ![]() |
The EH Series maximises its capacity and wide MPPT voltage range through the 33% DC oversizing capability. The EH Series is GoodWe’s only residentially manufactured Hybrid Inverter range. The EH Series is compatible with high-voltage batteries, being able to be connected to lithium-ion batteries in the 85V to 450V range. | ![]() |
The MS Series is GoodWe’s industry-leading 3 MPPT’s single-phase model available in 5-10kW sizes. It is a small but powerful inverter, weighing up to 22.5kg and offering as much as 100% DC oversizing. | ![]() |
The MT Series is focused on commercial applications with 3-phase models up to 80kW in capacity. These inverters feature 4 MPPTs and can oversize DC input by as much as 50%. | ![]() |
How Much Does GoodWe Inverter’s Cost?
GoodWe inverters are manufactured in China and have reached a significant scale of production meaning they can offer cost-effective prices.
Indicative pricing
GoodWe Inverter Model | Indicative Price Range |
GoodWe XS Series 3KW Inverter | $500 to $600 |
GoodWe DNS Series 5KW Inverter | $600 to $800 |
GoodWe MS Series 10kW Inverter | $1,250 to $1,400 |
Keep in mind that inverter costs generally only run between 10-20% of your total system, so often it is worth investing in a high-quality inverter given this will have a large impact on the efficiency and performance of your Solar Power project.

GoodWe Inverter Efficiency
An important aspect of getting the most value out of a solar inverter is choosing an appropriately sized inverter to optimise the solar panel system efficiency. To read about the importance of inverter sizing and system efficiency click here.
Residential inverter efficiency standards are generally 95 to 98 per cent, GoodWe inverters meet these standards. The least efficient GoodWe inverter is the NS Series 1kW which still records a 96.5% max efficiency. Asides from this one inverter all GoodWe inverters have at least 97% max efficiency.
Several GoodWe models have over a 98% max efficiency, one of these models is the SDT Series 10kW. This Three-Phase Dual-MPTT string inverter has a 98.3% max efficiency, making it one of the industry’s more efficient inverters.
GoodWe Inverter Warranties
In Australia, all CEC-approved GoodWe inverters come with a standard 5-year manufacturer’s warranty. For the DNS and MS series, Goodwe offers an additional 5 years where they will replace the ‘parts-only’. In years 5 to 10 the customers would receive the replacement parts for free, but would still be required to pay for delivery, all labour costs and any taxes/duties.
In 2019 Goodwe launched an online warranty extension service. Customers can conveniently extend their warranty periods up to 25 years depending on the model of the inverter, simply by entering the serial number via their online portal and following the prompts. This needs to be done within 6 months for inverters above 25kW in capacity and within 2 years if below 25kW in capacity
The Limitations of Goodwe’s Inverters
GoodWe inverters won’t perform as well as micro-inverters or power optimiser solutions in partly shaded conditions. If there are trees above your roofline on the North, East or West side of your house then it would be worth discussing the pros and cons of alternatives with Solar Choice before deciding on technology.
Additionally, the 5 year full warranty offered by GoodWe is rapidly becoming one of the shortest inverter warranties offered in Australia with many of the growing Chinese companies offering a standard 10-year warranty. As we’ve discussed previously, a warranty is only worth something if the company providing it is still around and there is an accessible route to claiming it if your Solar Installer is no longer around – by all available measures GoodWe looks to be a good bet.

So, Should I Buy GoodWe inverters?
In some cases, GoodWe may be the only string inverter option that can be used for houses with multiple roof aspects.
Technically speaking, GoodWe’s inverters are able to offer similar characteristics to some of the premium options in the market.
We consider GoodWe to be one of the Chinese inverter manufacturers with a better reputation with a good history in the Australian residential solar market. Their inverters are price more competitively that the European or micro-inverter options so can offer some savings for customers looking to maximise value under a particular budget.
Example of a GoodWe Commercial Solar Project
In March 2020 the largest solar power plant in the state of Espirito Santo, Brazil commenced operation. The plant is located on two campuses of the state’s largest university, Universidade Federal do Espirito Santo (UFES).
The power plant will generate approximately 7.7 million kWh of electricity a year. This will reduce the largest campus’s electricity consumption by almost 50% and reduce the university’s total power consumption by 30%. Due to the system’s size, the initial investment will be paid back in less than 5 years.
The inverters used in this power plant system are from the GoodWe MT Series. This commercial inverter is ideal for large-scale roof and power plants. The MT Series comes in 50-80kW sizes, it is a three-phase string inverter with 4 MPPT’s that can achieve a max efficiency of 98.8%.

Reviews from Australians who have installed Goodwe Inverters
It met the solar system objectives
The original invert 5kw Growatt installed in 2012 failed in 2020 2 years after upgrade from 3kw of panels to 5kw in 2018.
Too early to comment
Best inverter
Excellent
Simple inverter and does the job. My panels are wired in string configuration so no fancy options here.
Easy to operate , and ready for future battery
All good at this stage. Does make a buzzing noise. Again did search online for the best value and performance and Goodwe was on top 5 list.
It has failed after 1 month
So far good
nil comment
Grea system
Seems to work and app works
So far so good, it's working perfectly.
Didn't need to install one
Competitive price, and high quality.warranty good.popular worldwide brand.
I like the app.
Why I chose the. 10kW Goodwe inverter was for similar reasons to why I chose the Jinko panels. I.e. very popular, widely used, well priced & furthermore, the Jinko - Goodwe combination is also a very popular & widely used panel-inverter combo. The key deciding factor for me choosing the Goodwe inverter was my AC Input is only 240VAC single phase, not 3-phase, & though there are also other popular & very decent brand inverters to choose from such as Fronius, Sungrow, etc., Goodwe offered a single phase, 10kW, 3xMPPT inverter. Most other brands only offered the above in 3-phase or only 2xMPPT in a single phase. This would mean I would need 2 x 5kW, 2xMPPT inverters from Sungrow for example, which also limited the panel distribution & layout that would yield the best results for my multiple single & double-storey roof configuration. The Goodwe was therefore a no brainer for my circumstance.
product seems good
all seems to be working well and am happy with results.
Goodwe have a pretty easy app to set up and ease. Have to connect it to your home wi-fi first.
no problems or issues as yet
appears to be as described
Yet to be installed
Does the job and has monitoring of energy consumed via the internet.
Good inverter
Eazy to manage
5 star
20kW inverter is VERY noisy (over 60dB measured). Do not install indoors, or where people work.
Told good mid spec inverter working fine at this stage only early days.
Great!
Great value. Very happy with its performance thus far.
Goodwe online and phone app to monitor usage is really good.
As above
Easy, efficient
Again only just installed
Model 8500-MS with 8.5kW output and 97.7% efficiency and a 10 year warranty. Has WiFi and remote internet access with great access showing updated figures every 5 minutes.
Great - only small quibble is that the SEMS Portal software sometimes fails to provide accurate graphs ( shows zero load for the whole day ) if the remote serve does not get all the scheduled meter readings.
I have a Goodwe Inverter & an Alpha Inverter. They're working really well. Quite small & compact. Very neat looking. The apps for the 2 inverters are really good!
Good brand.
Fine
Goodwe haven't responded to my request for an explanation of the bizarre graph either.
Seems to recording same as monitoring is
Looks good so far, am awaiting my first bill
Software is very easy to use.
Again..lets see how it lasts
The inverter seems to be working well. The mobile app lets me track when and how much power is being generated so that I can run my larger appliances during these times.
I had some trouble getting the monitoring onto my iPhone but now everything is great.
Had good reviews and with head office interstate in case warranty is needed
Easy to use
easy to set up and use built in wifi monitoring, switches on with little sun and continues till all light gone. no issues at all
again, whilst no account has been rendered yet, there's been no problem with the operation of the system to date.
The panels themselves are working well, but there is a communication fault in the Goodwe Inverter which 6 months after I reported it has still not been rectified NW Solar Power. I have had to put WA Consumer Protection on to them to force them to take action to rectify the fault.
Excellent
Good price and warranty
good
Good so far.
