Growatt Reviews 

Battery not charging but contacted Growatt a support and through WhatsApp they got me sorted. Thank you Lingxuan🙏

Very competent and courteous field engineer (Owen Gao) who carefully monitored the performance of the entire house electrical power production system
for several days after fixing the original problem, finally declaring that everything was definitely now functioning properly.

Had a solar system installed by another company including a Growatt AC Inverter and battery. I wanted to start charging the battery from the mains overnight on my electricity provider's cheap rate. Asked Growatt through their app how to configure the system to do that. They responded very quickly, set it remotely but also sent me instructions. It worked but I received an error message when the battery was full. Again responded quickly and connected me to a WhatsApp chat with a technician who tried to update the firmware remotely. That failed so they sent a USB stick in the post. That also failed so they replaced the AC Inverter under the warranty. Now seems to be working fine. All done very quickly, responsively and helpfully.

Had an issue with a PV system that had started malfunctioning after British Gas installed a Smart meter. Found the Growatt support quick and the direct Whatsapp conversation resolved the issue, all done in a morning. The engineer Lingxuan found the issue quickly via photos (CT clamp in the wrong place) and all resolved. Excellent service

Trying for several months now to get support from growatt. Got some response in the 2nd/3rd week of January, issues didn't get resolved though, and haven't had any response for several weeks now.

Update: got some response from Growatt in march, to which I responded; I guess now it will take another couple of weeks before I hear from Growatt again :( My issues aren't resolved yet:(

The service from Growatt, especially the direct WhatsApp support, leaves nothing to be desired. All issues were addressed and resolved within a reasonable timeframe (under 24 hours).

However, it would be great if the engineers at Growatt could find the time to provide an API. This would allow interested end customers and installers to directly retrieve data from the inverter without using the cloud.

Relying on the cloud creates a burden for Growatt due to the high number of requests and also introduces significant delays—currently around 5 minutes.

In the context of the energy transition, having an API would be extremely beneficial. It would enable various smart systems to optimize EV charging, control smart home devices, and much more.

Customer service is sorry. Worst in the industry. 4 different answers for 1 problem... no solution. the best thing a growatt inverter is for is a boat anchor. tech support was very sarcastic and disrespectful.

Terrible. Their Infinity 1500watt off grid battery does not even work for 1200watt tools. + They did not read the e-mail properly and when I clarified it they simpley never responded.

Operatore impeccabile e disponibile!

I installed a sph10000tl-hu-us in mid November, and the system ran great. Then on or about Dec. 9th the inverter started throwing out fault codes randomly. (e.g. over battery current, estop pushed, buss error. Then it de sided to shutdown. After rebooting it, it started up and ran great.Then it did this again a couple more times. I called Growatt (12/9/24) and they downloaded new firmware. The inverter again ran for about a month with zero problems. Then on 1/9/25 it started to limit the battery output to 60% and showed random charting on the shine software. The math was all wrong in the charts. The funny thing is, I had a second one on order, I have since canceled the one on order, pending the outcome of these problems. I am sure that these problems are software related. I had one problem to start out with, now they have been resolved and I have a whole new set of problems. My big thing is I can't understand in both cases the inverter worked for about 4-6 weeks before having problems. I may end up scraping this 3 month inverter for two of something else.
Thanks for your response. The only problem is that I wrote this on 1/19/25, your response came on 2/14/25. Moreover You are just now sending it to your team in China. Your US Team is useless. I am sorry but I don't call this customer service, when it take this kind of time to resolve a problem. After fighting problems with your inverter, I ended up scraping a 3 month old, $3000.00 inverter. I purchased a EG4 Flexboss21. I installed it set up all the settings, it started right up and haven't had a problem with it. Would you like a used inverter back for $3000.00? The ten year warranty means nothing when you can't get help.
Very unsatisfied Customer

Having had very bad experiences in the past with inverters, batteries and the fitters who fitted them it was a pleasure to have the support of Growatt. Thank you so much.

I briefly wanted to express my thanks to Growatt for their service. Our issue was addressed and resolved thanks to Gennaro who I communicated with during the process. Gennaro was completely professional & courteous and, as a bonus, spoke very good English. Again, thanks for handling matters the way you did.

GROWATT AI is erroneous beyond belief. DO'NT USE IT. It seems to have only one purpose; to wear down the batteries.
Support of this new feature is NOT existing and you won't receive any intelligible response even though you document any error properly

Here's an excerpt from a mail:
Hi Terence

You claim “The battery charges when the import tariff (tax included) is low, and discharges when the import tariff is very high”. This is absolutely NOT true; it starts discharging as soon as it has finished charging. Which is actually exactly what your diagram reveals!

GROWATT claim that the AI need to learn out consumption pattern, and you claim the opposite.

The guy who helped me was very helpful and he came to my house to fix the issue in very short time. Strongly recommend.

Excellent knowledge and professionalism.

I have been told by an emergency solar tech my converter is toast after losing power late one night.A large boom noise was coming out of the switch board when trying to turn on as well.This callout was a/h and was over 400 bucks.Contacted sunboost who asked for photos and electricians report.Havent heard from them for a week .Very hot ,bills just climbing every day.I emailed again and got a response with all these electrical readings needed and to be photographed.They now expect me to get another sparky out for this?? Another 300 bucks min.As it stands It is going to be cheaper for me to get my own inverter .Is this why they prolong it?And why dont they demand sunboost check the inverter.
Dont want another growatt product.

I have done over 2000 Growatt installations and Hands down they are the best at looking after Warranty and there after service is By far the best i have came across and we work with all brands in Solar and Battery.

Big Shout out to Jianye,Owen and Jin Bin

Thanks team Growatt

This is my second Growatt same Make and Model,first one failed in first 60 days, they backed it.. then it ran for 2 yr and 6 months, then it Failed again. out of warranty.. I purchased a second of same make and model as a backup since I am OFF Grid. Have to have Solar controller for home power.. Installed Feb 2024, it Failed Oct 3, and I am still waiting on Growatt of Resolve the Failure and the group I was working with., told me to move to after sales in another country.. Now over two months with no Solar power, off grid, not able to make coffe or toast.. I contacted the After Sales Mgr via Email that was given. No Reply as well the associated Technical team, still after 5 days of sending contact NO Response.. Never Again.. Never Recommend Growatt. They may have descent product, but the Service, customer Service is Poor, Extreamely Poor.

Typical experience from China, when it goes wrong you cant get hold of anyone! Might as well of chucked £700 down the drain. No return calls, no return emails, tried everything, buy British and at least you can talk to someone. Second time I have been caught out by the Chinese, never again

We changed our broadband provider and after that our ShinePhone app was not working. We contacted Growatt who organised an engineer to contact us by WhatsApp. We had a clear and very helpful video call with Jack who showed us what to do and everything is now working perfectly.
