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

Dennis Brown · May 2026 Trustpilot

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

michael fairhurst · May 2026 Trustpilot

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.

Hugh Speirs · Apr 2026 Trustpilot

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.

Andy Thomas · Apr 2026 Trustpilot

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!

Emergency response — rate card

Remote triage
Free if we can’t fix it

Free if we can't fix it remotely. If we do fix it remotely, you pay the remote-fix rate only.

On-site callout (BH)
from £295

Business-hours emergency callout — diagnosis + scope of any larger remedial work.

On-site (out-of-hours)
from £449

Weekend, evening or confirmed-safety same-day attendance.

Commercial inverter swap
from £1,200

Labour for three-phase / large commercial inverter replacement. Part sourced separately at cost.

What we respond to
Inverter failure

Complete shutdown, error codes, overcurrent faults, grid relay failure, or intermittent tripping. We diagnose the root cause and carry out on-site inverter replacement where required — SMA, Huawei, Solis, SolarEdge, GoodWe, Fronius and others.

Generation loss

Sudden or gradual drop in kWh output. Could indicate string faults, failed optimisers, partial shading from new obstructions, soiling, or degraded panels. We compare actual performance against expected yield and isolate the cause.

Monitoring offline

System reporting stopped — data gaps, inverter communication lost, sensors showing stale readings. Often resolvable remotely via firmware reset, network reconfiguration, or CT clamp recalibration.

Battery storage faults

BMS errors, charge/discharge failures, cell balancing warnings, or thermal shutdowns on commercial battery arrays. Module-level diagnosis and coordination with the battery manufacturer where warranty claims are applicable.

Safety alarms

Ground faults, arc faults, DC isolation failure, or damaged cabling flagged by the inverter or external monitoring. We attend, safely isolate the affected circuit, provide a written safety assessment, and scope the remedial repair.

Export + G99 issues

Export limitation not working correctly, DNO compliance faults, or G99 relay tripping unexpectedly. Reconfigure export settings, verify protection relay parameters, and ensure the system meets its connection agreement.

How emergency repair works — 5 steps

1
Report the fault

Use the form below or call us directly. Provide as much detail as you can: error codes, which inverter is affected, when the issue started, and whether the system is still generating. The more we know up-front, the faster the triage.

2
Same-day remote triage

An engineer reviews monitoring data, error logs, and system history remotely. Many faults — communication errors, firmware issues, export limitation problems — can be diagnosed and resolved without a site visit. Remote triage is free if we cannot resolve remotely.

3
On-site attendance

Best-effort next-business-day on-site attendance. Our engineer attends with the tools, test equipment, and — where pre-identified — replacement components needed to resolve the fault in a single visit. Out-of-hours callouts available for confirmed safety issues.

4
Repair or written quote

Faulty inverters swapped, failed strings reconnected, isolators replaced, monitoring reconnected, safety issues remediated. Any larger remedial work is quoted in writing before we proceed — no surprise invoices, no work without your sign-off.

5
Written fault report

Every callout concludes with a written report: diagnosis, work completed, parts replaced, recommendations. Suitable for sharing with insurers, landlords, facilities-management teams, or the DNO if grid-side issues were flagged.

FAQ

Commercial emergency repair — frequently asked questions

Same-day remote triage during business hours — we acknowledge the fault, pull monitoring data, and start diagnosis. On-site attendance is best-effort next-business-day subject to engineer availability and travel distance. Out-of-hours and same-day on-site available for confirmed safety issues, with the out-of-hours premium applied.
Same no-fix-no-fee model as the consumer side: remote triage is free if we can't fix the issue remotely. The callout fee is from £295 business hours, from £449 out-of-hours. Parts and any larger remedial work are quoted in writing before we proceed — no surprise invoices.
Yes — every brand, every installer. We are not tied to any manufacturer or installer network. Our diagnostic is based solely on what the equipment is doing on site and what the monitoring data shows. If the original installer is no longer trading, we can also reconstruct the documentation paper-trail you need for insurance or warranty claims.
All major commercial inverter brands: SMA, Huawei, Solis, SolarEdge, GoodWe, Fronius, Sungrow, ABB, Ingeteam. Commercial battery storage from BYD, Pylontech, GivEnergy commercial, Tesla Powerpack. Three-phase, string and micro-inverter configurations all supported, plus residential brands found on smaller commercial sites.
For pre-identified failures, yes — if remote triage confirms an inverter is dead, we source the replacement before the visit so the swap happens in a single trip. For complex commercial inverters with long lead-times, we attend first to confirm the diagnosis, then schedule the replacement once parts are sourced. All commercial inverter replacement uses the from £1,200 labour plus the part.
Yes. Every emergency callout concludes with a written fault report detailing the diagnosis, work completed, parts replaced, and any further recommendations. The report is suitable for sharing with insurers, landlords, facilities-management teams, or the DNO if grid-side issues are flagged. If the fault triggered safety isolation, the report documents the assessment and the re-commissioning steps.
You get a written quote before any extra work begins. The callout fee covers the diagnosis and the work originally scoped — if the diagnosis reveals additional faults (failed strings, BMS issues, structural problems), we scope and quote them separately so you can decide whether to proceed now or later. No work happens without your sign-off.
If the emergency reveals the system needs ongoing technical oversight — common when the original installer is no longer responsive — we can transition you onto our system-takeover service, which provides baseline audit + documentation handover + ongoing monitoring. The decision is yours.
