Growatt, officially known as Growatt New Energy Technology, is a Chinese inverter manufacturing company that has been providing some of the most technologically glorious inverters for solar lovers since 2010. Here in this Growatt inverter review article, I’m going to talk about all the important aspects of the solar inverter that you should know before committing.
Their facility covers an area of 200,000 square meters and they have an annual output of 20GW. That is an impressive number for a company that has only been operating for about 11 years. Growatt is a brand that believes in constant improvement, so they heavily invest in research and development in order to keep up with the constant progress that science has to offer.
Over time, they have recruited more than 400 engineers, each of whom has experience of no less than 15 years. Their hard work and dedication did not go unnoticed because they obtained an ‘All Quality Matters’ award by TÜV Rheinland for its commercial and industrial (C&I) inverter – MAX series and residential storage battery – ARK series.

According to IHS Markit, a leading and globally recognised source of critical information, Growatt has made it to the top ten list of solar inverters. That is perfectly aligned with their vision because they did take an oath to become the world’s largest supplier of smart energy solutions.

When they started their journey, they envisioned a world where everyone has access to green energy and worked towards it. Now Growatt operates in a total of 14 countries, gaining huge success and fame. Even in the local Australian market, they have already paved the way to their glory days which started in 2012.

Is Growatt a Good Brand?

You might be wondering what is it that Growatt does that makes them so unique from other brands? First of all, they are a smart energy solution company that specialises in solar inverters. Not only that, they are so dedicated to their craft that they invest a lumpsum amount of money in research and development, all in the search for the best solar inverter that surpasses every limit and even their own sublime creations.
With over 400 engineers working towards perfection, Growatt managed to spike up the efficiency rate of the inverters as high as 99%. Also, by maintaining a firm QC (Quality Control) system, they ensure top-notch quality. But don’t forget, their products are highly affordable. So, anyone who wants to contribute to society by going green they have an option that is both great in quality and price.
So, to answer your question, is Growatt a good brand? YES! without a doubt, I can assure you that Growatt is, in fact, a phenomenal brand.

Where is Growatt Inverter Manufactured?

Almost all of the components of a solar system available in the market of most brands, starting from solar panels to inverters as well as batteries, are now being manufactured in China. Growatt follows the same path.
They are a Chinese company, and they also manufacture all of their inverters in China. It makes sense for them to be manufacturing in China because, being a large country, they have an abundance of skilled labourers. So, it makes the production cheap, ultimately the price of the finished goods cheaper. A Top-notch inverter at a great price, that’s a bargain I’m sure you can’t say no to.
However, they have offices all over the globe; for instance, they have an office in UK, Germany, and in the USA as well.
What about Australia, you might wonder, well for Australia they have not one but two different offices in different locations. They do recognise their demand and popularity among Aussies; thus, they have two offices in Australia. One is located in Sydney, which is the first office, and the other one is in Melbourne. If you ever find yourself struggling with anything regarding your Growatt inverter, instead of going a to a third party, for example, your installer, now you can directly contact the Growatt office.

Some Drawbacks to Mention

While Growatt invert is as amazing as it comes, but all good things in life have some minor hiccups to overcome as the journey continues. It’s not a different story for Growatt. Here are some of the drawbacks of this inverter-
  • Growatt does not come with panel optimisers. So, if you face shading issues while using the solar panels, you have to get panel optimisers separately. Which is not a deal breaker, but something you should be aware of before committing.
  • While joining the industry, they had their eyes set on creating only entry-level inverters, which propagated some reliability issues. The 5000MTL 5kW model showed some significant problems which were heavily denounced.
  • Despite its seasoned and magnificent performance against high radiation (score A grade) and medium radiation (score B grade), the topic of its dependability was addressed.
For all the above reasons, they had faced their fair share of harsh criticism at the beginning of their journey. But Growatt came out of the dark alleys like a true veteran, and now they do business in more than a dozen countries.
They might not have been in the solar market for a long time as other renowned inverter manufacturer companies, but their improvement of the latest inverters over their predecessors and their establishment of the local offices with omniscient customer supports is hugely noticeable.
Now that you know about the drawbacks, you must know all of the good things about the Growatt inverter, it’s only fair! They have more strengths than weaknesses to flaunt.
