Owen was really good when I had a problem with my inverter I was appreciative of him walking me through the problem and giving me honest feedback on when I could expect a resolution. All has been fine since the new inverter has been installed

From scheduling to completion, every aspect of Owen Gao's service was perfect. Punctual arrival, clear communication, efficient repair, and thorough cleanup - truly comprehensive professionalism.
Battery charging error
I had an issue with batteries not charging from the inverter which was caused by a control board malfunction on one of the batteries. I reported it via the installer and the growatt engineer was in touch within 48hours and attended site a day later. The fault was identified, part replaced and within an hour and half the system was tested and running perfectly again. Thanks Jianye

Owen Gao from Growatt UK provided exceptional on-site repair service. His technical expertise and efficient problem-solving got my solar system back online in no time. Truly professional work.
Terrible company with terrible…
Terrible company with terrible products. Growatt has again and again proven themselves to be the worst manufacturer when it comes to just about everything that is important. 1. Their products are cheap garbage. I am not against chinese manufacturers, but Growatt is terrible! There are others like Huawei or Sigenergy which make excellent products with low fail rates and good support. The few Growatt inverters we have installed, most of them have had issues not related to the installation resulting in having to contact Growatt. 2. The after-sales support. There is just about no support to speak of, emails need to be sent 4-5 times until you get a reply and phone calls get declined all the time. You're lucky if you get a replacement part. 3. The software. Their software is cluttered, hard to understand and outright bad. We have had multiple instances where inverters that we have not installed are registered to our company in other countries, how could that happen? There are 2 different portals with different account logins, even the translations are terrible. We have not bought a Growatt product in over 1.5 years but their issues still plague the company I work for, not to mention the customers!!!!

Owen Gao went above and beyond during the repair visit. Not only did he fix the immediate issue, but he also conducted a full system check to ensure everything was optimized. Such thoroughness is rare these days.

Clear communication from start to finish! Owen Gao kept me informed throughout the repair process, explaining technical details in understandable terms. The follow-up message with warranty confirmation was particularly helpful.
Excellent service from engineer
We were having problems with our battery not charging. This battery was only 6 months old after the previous one had failed. This could not be resolved remotely so the engineer came out within a couple of days and replaced some connectors. Unfortunately this did not resolve the problem so the motherboard was replaced on the next visit. However, when it was evident that this was also not the issue, the battery was removed. A replacement battery was installed at the next visit. Let’s hope it lasts longer than the last one! The engineer was very helpful and kept us fully informed with what was happening. He always tried to find a mutually convenient time to visit. Can’t fault his service.
Excellent fast service
Excellent fast service with great contact. Engineer who came was really helpful and knowledgeable. System was back up and running quickly and also helped setting up off peak charging.

I contacted Growatt support when my solar system started misbehaving...effectively not charging as it should have from mains supply. The technicians quickly identified the problem and provided firmware updates. Following the teams instructions I was able to install these via the inverters USB port and all is well now. Excellent, friendly and efficient service!
