Overview of GoodWe – Company History
Jiangsu GoodWe Power Supply Technology Co Ltd (trading as GoodWe) were founded in 2010 in Suzhou, China. GoodWe are well known for their broad range of single phase, three phase and hybrid solar inverters. Goodwe have expanded into battery solutions and recently launched an EV Charger.
GoodWe has established themselves as one of the largest volume global solar inverter manufacturers with over 5,000 employees.
GoodWe’s industry excellence led to a pivotal partnership with General Electric (GE), who awarded them an exclusive licensing contract for global sales, solidifying GoodWe’s position as a solar inverter industry leader.
Just two years after their inception, in 2012, Goodwe expanded to Australia and opened a Melbourne office.
A Brief Rundown on GoodWe Inverters
A solar system’s inverter converts the DC electricity from solar panels into AC electricity compatible with the grid. There are typically two types of inverters used: string inverters and 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 Review – Points of Difference
Range of Hybrid Inverter Options
GoodWe offers the market’s broadest range of storage inverters. Their lineup includes single-phase low-voltage hybrid solutions (ES, EM), single-phase AC coupled retrofit solutions (SBP), single-phase high-voltage hybrids (EH), and three-phase high-voltage hybrids (ET). This variety makes GoodWe an ideal choice for installations requiring hybrid inverters or for those planning future battery installations.
Multiple MPP Trackers
Maximum Power Point Trackers (MPPTs) determine how many roof orientations a string inverter can handle. Panels on the same MPPT with different tilts will perform as well as the least efficient panel, affecting daily output. GoodWe inverters, offering more MPPTs than competitors across various sizes, are a popular choice. Their MS series is the only single-phase inverter with 3 MPPTs in the Australian market. This makes GoodWe MS ideal for installing panels on multiple orientations, like North, West, and East sides of a house, without resorting to costlier micro-inverter or power optimiser solutions.
DC Oversizing
DC oversizing means installing solar panels with greater capacity than the inverter’s output potential. While it may appear to waste power, considering efficiency losses and the fact that solar panels rarely reach their maximum wattage, oversizing by 33% is cost-effective and allowed by the Clean Energy Council’s guidelines. Oversizing beyond 33% benefits those with a battery, as it enables storing excess DC energy.

How does Goodwe’s efficiency rank?
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. GoodWe’s most popular DNS single-phase series of inverters have a maximum efficiency rating of 97.8% which compares very well against the competition.
Several GoodWe models have over a 98% max efficiency, one of these models is the SDT Series 10kW. This Three-Phase Dual-MPPT string inverter has a 98.3% max efficiency, making it one of the industry’s more efficient inverters.
GoodWe’s Warranty Offer for Australian Customers
In Australia, all CEC-approved GoodWe inverters come with a standard 5-year manufacturer’s warranty. For the DNS, MS and G3 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.
This makes GoodWe’s warranty offer below average as most inverters on the market come with a full 10-year warranty.
The good thing about GoodWe’s warranty offer is that they have local staff at their office in Rowville, Melbourne to support local customers. They also have an Australian website and are easily contactable via email or phone.
The Limitations of Goodwe’s Inverters
GoodWe inverters underperform compared to micro-inverters or power optimisers in partially shaded conditions. If your roof has shading from trees on the North, East, or West sides, it’s advisable to weigh the pros and cons of alternatives with Solar Choice.
GoodWe’s 5-year full warranty, while competitive, is shorter than many newer 10-year warranties offered by growing Chinese companies in Australia. However, the true value of a warranty depends on the issuing company’s credibility and the ease of the claim process. In these aspects, GoodWe stands out as a promising option.

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, with some impressive efficiency ratings.
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 is great to have an app to watch progress
I’m happy with the inverter and the app monitoring
No idea, I still don't have a working system
I was looking a a Fronius, but actually dropped back to a Goodwe as it basically did what the Fronius would do (within reason, with 3 mppt functionality nearly getting to the Fronius level efficiency), but at a fraction of the price. I did this because I wanted batteries in the future. I could go something like the BYD modular system OR I heard the Powerwall 3 was coming and I that it would be combined inverter AND battery. So If I rip and replace... I would lose a lot less (If it is economically viable). I just didn't want to wait longer for panel instal. But the Goodwe seems to pull heaps of solar for now and I am happy!
Discreet, tidy look to final installation, seems to work well
So far so good. Working well at this stage.
Review left 3 years after system installed
Wasted Investment: "Choosing GoodWe has been one of the worst investments I’ve made. I’m stuck with a system that doesn’t deliver the savings or performance I was promised, and I regret not going with a more reputable brand.
As above hasn’t been up long enough to comment on it yet
NO issues so far (not incredibly ugly to look at) and WiFi app / system is working well
Inverter functions as planned. Monitoring platform pretty basic, only looks at generation so not really that helpful (would be good if it reported against consumption also)
The inverter and the app gives us all the information we need
Having hiccups with the monitoring could be our internet as it is WIFI. Drops in and out
Seems to run OK. Comms hookup a bit annoying.
It seems good except that I cannot monitor the output on my iPhone.
very easy to monitor output. it is performing as expected.
So far the app and monitoring are going great
App very informative. Took me a bit to work out but watched a YouTube clip with a good explanation.
Yes, we are happy with the Goodwe inverter. The monitoring app works well enough for what you need.
My wifi doesn't seem to be strong enough for the inverter to connect and the app to work. Nexa have been helpful but I think I need to call the app people, as suggested. In saying that, I am not tech savvy, so it could be just me.
I have become aware that the inverter is not compatible with batteries if I decide to get them in time. This is hear say and apologies if its incorrect.
