Sungrow Inverter Review | A Worthy Tier 1 Inverter or Not?

sungrow inverter review
With a net worth of 1.5 billion dollars, Sungrow is a proud Chinese renewable energy company that started its journey in 1997. Back in the day, having a reliable power supply in every household was quite a struggle for many rural Chinese people. The renewable energy sector wasn’t as strong as it is now. That is when a professor of Hefei University, Mr Cao Renxian, decided to take on the task of researching a developing a sustainable way to convert renewable energy resources into reliable ones. And that is how Sungrow, the second-largest inverter manufacturers after Huawei were born. It was never about a mere business to only generate profit from; rather, it was a solution to general people’s problem, which later on became a giant of the industry for all the right reasons.

Now Sungrow is a global company that operates in more than 150 countries. With the help of dynamic research and development, Sungrow has made its place on top, so you better believe a huge chunk of their investment goes dedicatedly for that. They are capable of producing about 90GW per annum. Fortuitously their inverters have been accredited by CEC Australia, TUV, UL, CSA, and other well-recognized international authorities.

Is Sungrow a Good Brand?

The definition of a ‘good brand’ is a brand that stands true to its promises, a brand that meets its customer expectation and tries to even surpass that. So, indeed Sungrow is not only a good brand; they are more than just a ‘good brand’.
They have been dedicating a lot of their resources to R&D just to improve and give the mass people the confidence to use clean energy in the cheapest and most efficient way possible. This brand in no way took a ladder towards their success; rather, they had put in twice as much hard work to achieve their status in the market as one of the largest solar inverter manufacturers.
Since 2012 they have been operating in Australia, and many experienced solar installers even compare their inverters to Fronius inverters. Fronius is a European brand that is an Australian favourite, but the catch is they cost twice as much. So, being compared to Fronius for a fraction of the price, moreover being chosen over Fronius in a number of cases, surely proves Sungrows’ position overall. And Solar Emporium also agrees.
Sungrow is such a company that truly does care for the environment, and their driving force is just not only the profit. They practice what they preach; that is exactly why Sungrow themselves are dedicating their resources to make their operations 100% green by the year 2028.

Where Is Sungrow Inverter Manufactured?

Sungrow inverters are mainly manufactured in China. This way, they cut down on cost, unlike some European companies. If your aim is to find an inverter that will perform like a champ yet won’t break your bank in the process, Sungrow is the way to go. There might be some stigma around brands that are based and built in China. However, in the case of green energy and technologies, Chinese companies are almost dominating the industry, and people are also widely accepting this bittersweet change. Why won’t they? If they are providing spectacular quality products, then nothing should come in the way.
While investing in any inverter, what you should rely on more than anything is numbers because numbers don’t lie; if the right numbers match in the right category, Bingo! So, try not to hinder your way towards experiencing a top-of-the-line inverter by relying too much on mere stereotypes.

Advantages and Disadvantages of Sungrow Inverter

While there are many advantages of Sungrow inverters, disadvantages are next to none in comparison to that. Here are some of them-


      • An average of 95% to 98% efficiency with all modules
      • Smartphone application to monitor the inverter
      • LCD display with most modules for easy inspection
      • Fantastic warranty periods
      • Aussies can apply for an additional warranty period on certain residential modules
      • The quality of the inverter is comparable to European brands like Fronius; however, the prices are not as high. The ratio of quality to price is praiseworthy
      • From 1kW to 110kW, single or three-phase, hybrid or no – Sungrow can fulfil any of your need


      • This is not necessarily a disadvantage, but the stigma behind being a Chinese born brand sometimes is considered as a disadvantage. Many customers tend to shy away when they get to know about Sungrows origins. It’s truly a shame

Sungrow Inverter Monitoring System (iSolarCloud)

Sungrow has its own dedicated mobile monitoring system, which can make your life a hundred times easier. With a touch on your smartphone, you can control your inverter by installing the iSolarCloud monitoring app using a working home Wi-Fi connection.
Previously they had an outdated monitoring platform which hindered user experience. What did Sungrow do about it? They listened to customer feedback and worked on it; as a result, now they have the latest monitoring app, which can not only regulate the inverter remotely but also show you status updates on important criteria. This app is simple and very easy to understand, so don’t worry; you don’t have to be a solar expert to make sense out of those numbers. Interface of the ISolarCloud solar inverter app

The old SG model had a buster regarding the consumption monitoring which later on got fixed with the latest models. A smart energy meter and a Wi-Fi dongle are all it took to solve the issue. Now, Sungrow offers a variety of dongles, meters, and data loggers for three-phase and single installations. Keep in mind that energy meters are required for export limiting and for energy storage systems to function. The Sungrow SH5K hybrid inverters come with an S100 meter & dongle included for your convenience.
Sungrow is a brand that didn’t leave anyone behind and put thought while designing their inverters. For those who consider an app of even smartphones to be an extra hassle in their way of enjoying clean power sources, Sungrow left a tiny screen on the body of the actual inverter. If you are one of those who consider solar to be a set and forget kind of deal, then that tiny screen will keep you updated when you feel like getting any updates at all. There is a solution for everyone in this family.

Sungrow Inverters' Efficiency

As a Chinese company, they are able to keep the efficiency numbers high while keeping the price as low as possible. That is a rare combination indeed.
