I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.
When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.
Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them
Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)
Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
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.
After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.
Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.
Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.
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 (their Trustpilot reviews don't lie!). 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.
This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.
I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

Common Enphase 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.
A panel showing as grey or N/A in Enlighten typically means the microinverter for that panel has stopped producing. It could be a failed unit, a loose AC connector, or the microinverter has tripped its own protection. Enlighten's panel-level view makes the exact location clear.
See diagnostic guide →If all panels show as offline in Enlighten, the Envoy gateway has lost contact with the microinverters or the AC supply to the array has been interrupted. Check the Envoy indicator lights and verify the AC breaker for the solar circuit is closed.
See diagnostic guide →Unlike string inverters, a failed Enphase microinverter affects only one panel. The Enlighten portal shows the affected panel clearly. We identify whether the unit needs replacement or if an AC wiring issue is the cause.
See diagnostic guide →The Enphase Enlighten portal shows no recent data. The Envoy (IQ Gateway) has lost its internet connection. The solar system continues generating normally — only the data stream to Enlighten is interrupted. Usually caused by router change, WiFi password update, or Envoy hardware fault.
See diagnostic guide →After a router upgrade or ISP change, the Envoy needs reconnecting to the new network. This is done via the Installer Toolkit app or the local Envoy web interface at envoy.local. We guide you through the reconnection process remotely.
See setup guide →Enphase Enlighten provides panel-by-panel performance history. If overall generation is below expected, we compare individual panel outputs to identify which microinverter or microinverters are performing at reduced capacity.
See diagnostic guide →Enphase IQ7 and IQ8 microinverters carry a 25-year warranty. If a unit has failed and is within warranty, we prepare the diagnostic evidence needed to support a claim with Enphase Energy Ltd. Your installer going bust does not affect the warranty.
See diagnostic guide →Enphase IQ8 series microinverters support 'Sunlight Backup' mode — the ability to power essential loads directly from solar panels during a grid outage without a battery. This requires specific wiring and configuration that many installers haven't completed correctly.
See diagnostic guide →Enphase Enlighten panel status guide
Enphase systems report status at the panel level rather than showing single error codes. Common Enlighten statuses: grey panel (microinverter not communicating), yellow triangle (reduced production), red (microinverter error state). Share your Enlighten screenshot when you book — we identify the exact microinverter fault from the panel-level data.

About Enphase systems — what you need to know
Enphase Energy makes microinverter systems — fundamentally different from the string inverters used by GivEnergy, Growatt, SolarEdge and others. Instead of one central inverter handling power from all panels, each Enphase panel has its own IQ microinverter (currently IQ7 or IQ8 series) mounted directly behind it. The microinverter converts DC power to AC at panel level. This means each panel operates independently — shading on one panel doesn't affect the others, and a single microinverter failure doesn't stop the rest of the array.
Monitoring is provided by Enphase Enlighten — a cloud-based portal that shows production at the individual panel level. The local Envoy (or IQ Gateway) collects data from all microinverters via powerline communication and pushes it to Enlighten. The most common searches we handle for Enphase: panel not showing in Enlighten, Enphase Envoy offline, Enphase microinverter failed, and Enphase installer gone bust. STS provides independent Enphase support across the UK — not affiliated with Enphase Energy Inc.
STS supports all major inverter and battery brands — not just Enphase. If you have a mixed-brand system or are comparing options, visit the brand hub.
