If your Growatt inverter is showing a fault code and you need expert diagnosis, a remote diagnostic identifies the cause and recommends the fix — usually within 30 minutes.

Communication was great and the engineer did a great job and even tidied up the existing wiring which made it look a great deal nicer than it did. Very happy so far and grateful to the team for their professionalism.
Sts does a extremely great job. Thank you.
I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration. So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.
Absolutely wonderful. Would recommend without hesitation. I had an issue I was thinking would never be fixed and they fixed it. Help, advice and support every step of the way. I can't recommend highly enough. Thank you so much ⭐
Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.
I contacted Solar Tech Support with an issuewith my solar and Ron went out of his way to help me. Despite the fact that I'm situated hundreds of miles away and he knew there'd be no business opportunity from my inquiry, Ron still chased solutions and helped me get an understanding of what I needed to do. I love working with people like this, people with integrity and service at the heart of what they do. I just wish hew was nearer!
Fault codes generated by the inverter in response to AC supply problems, DC overvoltage from panels, or temperature issues. These typically cause the inverter to stop generating.
