Absolutely amazing service. Ive had a couple of issues with my Givenergy system and couldn't manage to get in touch with Givenergy after they went bust. So I was searching on Google and came across Rons number. I sent Ron a WhatsApp message and got a prompt reply and he resolved the problem I had with my system. I can't recommend Ron enough its not often you get such a good service in this day and age. If you are experiencing issues with your solar system Ron is the man to contact.

My 3-year old GivEnergy Solar/Inverter/Batteries installation went down with all generated electricity going to the grid and absolutely no help available from the Administrators! Thankfully, I found Solar Tech Support and Ron, who used to be a GivEnergy installer. His knowledge and ability are phenomenal and he sorted everything out remotely. I cannot recommend him more highly and a really pleasant guy to deal with! Very many thanks Ron!!
Solar Tech Support is an absolute lifesaver. My solar and battery system stopped working completely, but after one quick phone call, they fixed the problem straight away. The original provider, GivEnergy, has gone into administration, leaving me entirely without support from the original installers. It was a terrible situation on GivEnergy’s part, but thankfully, Solar Tech Support came to the rescue!
We have a GivEnergy system, both GivEnergy and our installer have gone bust! Ron was able to remotely log in to our system and sort the issue within about 30mins. Would definitely recommend and will be using in future
My issue was assessed and resolved quickly once the engineer was able to look at the problem. This took a little longer than I had expected (3 days) and keeping the PC on all day/everyday with Sentinel open was a little cumbersome I thought. That said, with little support coming from GivEnergy nowadays it was good to find someone who knew the platform and could resolve my issue.
Absolutely fantastic customer service. The team were incredibly helpful, responsive and genuinely willing to do everything they could to help get things sorted. With all the uncertainty surrounding the future of GivEnergy at the moment, it was particularly reassuring to have people who were knowledgeable, approachable and prepared to step in when needed. After a glitch with my firmware update caused problems with my system, these guys really did come in and save the day. They took the time to investigate the issue, explain what was happening and work towards getting everything back up and running. It’s refreshing to deal with a company that genuinely seems to care about its customers and is willing to go the extra mile when something goes wrong. Superb service from start to finish. Many thanks for all the help and support — it’s very much appreciated. Highly recommended.
Common Growatt problems we diagnose
Every fault below has a proven diagnostic path. Click through for the specific page or book a diagnostic if you're unsure.
The inverter has detected that DC isolation has dropped below 1MΩ. This is a genuine safety event — not a nuisance trip. Common causes: cracked panel backsheet, damaged DC cable, water in a junction box or connector. Requires on-site investigation.
See Error 04 guide →Growatt documents 117 as a relay fault, raised when the relay check fails six times. Something is wrong with the grid-isolation relay or its circuit. Growatt's remedy is one restart, then a warranty replacement if the code returns.
See Error 117 guide →DC insulation resistance has dropped below 1 megaohm. The inverter shuts down as a safety measure. Causes include MC4 water ingress, UV-damaged cables, cracked junction boxes, and rodent damage. Requires IR testing to locate the fault.
See isolation fault guide →Inverter powered but generating nothing. Could be a DC string fault, isolator not closed, or protection trip not yet cleared. Check the ShinePhone app for error codes and the ShineTools log.
See diagnostic guide →App shows no data or inverter appears disconnected. Could be the WiFi logger (ShineWiFi or ShineLink) offline, a cloud-side ShineServer outage, or the logger hardware failed. The system usually keeps running, but offline doesn't prove it, so check the inverter's own screen.
See diagnostic guide →The ShineWiFi stick or ShineLink module requires 2.4GHz WiFi. After a router change, it needs reconfiguring via the ShineTools app or web interface. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting.
See diagnostic guide →ShinePhone shows power output below expectations. Could be a string performing at reduced capacity, soiled panels, or a configuration error. We review ShineServer historical data to identify the fault pattern.
See diagnostic guide →New homeowner needing to register the system, or taking over a system registered to an installer's account? Covers first-time setup, orphaned account transfers, and what to send to Growatt UK to reclaim access.
See setup guide →Growatt fault code index
Growatt error codes appear on the inverter LED display and in the ShinePhone app. Common codes: Error 04 (insulation failure), Error 117 (relay fault), Error 107 (sampling difference is big), Error 122 (bus voltage too high). Share your exact code when you book — we identify the root cause as part of the remote diagnostic.

About Growatt systems — what you need to know
Growatt is one of the UK's most widely installed inverter brands — particularly popular with budget-conscious installers. The MIC, MIN, and MOD series cover residential string inverter installations. The SPH and SPA series are hybrid inverters with battery integration capability. All Growatt inverters display fault codes numerically on the front LED panel and report them to the ShineServer cloud via the ShineWiFi or ShineLink logger. Growatt's ShinePhone app provides remote monitoring and fault history access.
The most common Growatt searches we handle are: Growatt Error 04, Growatt Error 117, Growatt ShinePhone offline, Growatt not producing, and Growatt isolation fault. Error 04 is particularly common in older installations where panel connectors or cable insulation have degraded — it is a genuine safety event, not a nuisance fault.
