I have a number of Growatt inverters
I have a number of Growatt inverters. My 8000 MTLP US had an issue but Growatt helped right away. That was about 5 years ago. I now have two Growatt SPF 12000 T DVM US inverters that are giving problems. The oldest one is about 4 years old and failed before and Growatt took care of it right away. It failed again last year and service was a bit slow. Now the new inverter I installed in January to replace the other has failed exactly the same as the first. Initially, working through my supplier they sent 2 replacement boards, that didn't fix it. Now my supplier gets no response from them, I get no response from them. I've tried contacting service online, their site won't accept e-mails, they respond saying fill out a form, but the form can't be filled out since it requires a code that won't work, then the site wipes out the request and you have to start over. I contacted their US office since the inverters are US split phase they sent me e-mail addresses of the people in charge of service in Asia where these inverters are, and I never heard back. So I have 2 inverters not working and no help whatsoever from Growatt and here it is the middle of July now, the failure of the newest one was 5 months ago. It only lasted 2 months after installation.
