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)

Tony Deacon · May 2026 Trustpilot

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.

Christopher · Apr 2026 Trustpilot

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!

Who this is for
🔧

You have a complex fault you can't resolve

The system is behaving unusually and neither the manufacturer support line nor your own diagnostics have identified the cause. You need a second opinion from someone who works at the engineering level — not a scripted helpdesk. We handle the diagnostic and give you a clear answer.

📋

You need an aftercare partner for your customers

You install — you don't want to be the first call when a battery stops charging eighteen months later. We provide structured aftercare support for your customer base: fault triage, remote diagnostics, and on-site repair. Referral and white-label arrangements available.

📄

You need an independent report

Customer dispute, warranty claim, or a post-install snag check that needs to be done by someone other than the installing team. We provide independent engineer's reports that are accepted by all major UK manufacturers and suitable for use in formal dispute processes.

Services

What we provide for installers

These services are available directly to UK solar and battery installers. All work is delivered by experienced solar engineers — not subcontracted.

🔍
Diagnostic overflow

Remote fault diagnostic — engineer overflow

When your own diagnosis hasn't found the cause, we take over. We review all available monitoring data, error logs, and system configuration to identify the root fault. You receive a written report with the cause, evidence, and recommended resolution — typically within 24 hours of receiving access.

From £75 · See remote diagnostic →
QA inspection

Post-install snag inspection

An independent on-site inspection after installation is complete. We check physical quality, commissioning, settings, CT clamp orientation, documentation, and cosmetic finish. Written snagging report gives your customer confidence — and protects you against post-handover disputes.

On-site · From £195 →
🛡️
Warranty support

Independent warranty claim report

A formal independent engineer's report to support a manufacturer warranty claim or customer dispute. We diagnose the fault, establish whether it falls within manufacturer warranty terms, document the evidence, and produce a structured written report. Accepted by GivEnergy, Sunsynk, SolarEdge, Growatt, Solis, and all other major UK manufacturers.

📞
Technical support

Installer technical support — engineer-to-engineer

Complex fault you can't crack, commissioning issue on a new install, firmware question, or manufacturer escalation that's going nowhere. We provide engineer-to-engineer technical support remotely. Confidential — your customer never knows.

From £75 · See technical support →
🤝
Partnership

Aftercare & maintenance partnership

A structured arrangement where we handle fault calls, diagnostics, and maintenance visits for your customer base — under your brand or ours. We triage incoming customer issues, resolve what we can remotely, and escalate to on-site where needed. Suitable for installers who want to offer a guaranteed aftercare service without carrying the overhead. Pricing based on customer volume.

Discuss partnership terms →
Installing commercial systems?

We provide independent O&M contracts, emergency repair, system takeover, and performance audits for commercial solar installations. If your commercial clients need ongoing maintenance or you want to offer aftercare without carrying the overhead, we can work together.

Process

How working with us works

No account setup, no minimum commitment for one-off jobs. Ongoing partnerships are agreed in writing before any work begins.

1
Get in touch with the details

Use the form below or call us directly. For fault diagnostic overflow, tell us the brand, model, what the system is doing, and what you've already checked. For inspections or reports, give us the address and any relevant customer background. For aftercare partnerships, outline your customer volume and what you need covered.

2
We scope the work and confirm the cost

For diagnostics and inspections, we confirm the cost before starting — no surprises. For ongoing partnerships, we agree a clear arrangement in writing: what's included, turnaround expectations, pricing, and escalation process. We don't start work until both sides are clear.

3
Work is delivered — report provided

Remote diagnostics come with a written findings report. On-site inspections include a condition report with photographs. Warranty reports are structured for manufacturer submission. You get everything in writing — you decide what to share with your customer.

Why work with us

STS was founded by an engineer who spent years in the solar industry at scale — running technical support teams and handling the kinds of faults that don't appear in the manual. We've seen most failure modes across most major brands. When you send us a fault you can't resolve, you're not going to a helpdesk — you're going to someone who has dealt with the same hardware.

We are genuinely independent. We are not tied to any manufacturer or distribution network, and we have no reason to recommend a fix that isn't the right fix. That independence is why our warranty reports carry weight.

We understand that working with an outside technical partner requires trust. Anything you share with us — customer details, site specifics, fault history — stays confidential. We don't contact your customers directly unless that's been agreed. We don't take on ongoing relationships with customers you've referred to us for a one-off job.

For installers who want a long-term aftercare partner, we're structured to handle that at volume — with agreed SLAs, a clear escalation path, and the engineering capability to back it up. Read more about how we work.

Brands supported
All major UK inverter and battery brands — GivEnergy, Sunsynk, SolarEdge, Growatt, Solis, Fox ESS, Huawei, SMA, Fronius, Enphase, and more
Coverage
Remote diagnostic UK-wide. On-site inspection across England and Wales — contact us for Scotland and Northern Ireland.
Turnaround
Remote diagnostic report: 24hrs standard, same-day for urgent. On-site: scheduled to suit the job. Warranty reports: 3–5 working days.
FAQ

Installer questions answered

Yes — we support all major UK inverter and battery brands including GivEnergy, Sunsynk, SolarEdge, Growatt, Solis, Fox ESS, Huawei, SMA, Fronius, Enphase, and Tesla Powerwall. If a system has been installed in the UK, we can support it. For less common brands, assess on a case-by-case basis — get in touch and we'll confirm. Full brand coverage is listed on the brands page.
Standard turnaround for a remote diagnostic report is 24 hours from receiving monitoring access and system details. For urgent faults — where a customer system is completely down — same-day response is available. Contact us directly by phone for emergency turnaround rather than using the form. For regular diagnostic overflow work, we're typically available within a few hours of receiving the referral.
Yes — all remote diagnostics include a written findings report. For warranty claims and customer disputes, we provide a formal independent engineer's report with fault evidence, photographs where applicable, a clear statement of cause, and a recommendation. These reports are structured to meet the requirements of all major UK inverter and battery manufacturers and are suitable for use in formal dispute processes. See the warranty claim support service for more detail.
Yes. We offer both referral and white-label aftercare arrangements. Under a referral model, you pass the customer to us and we handle the relationship directly. Under a white-label model, we handle all customer-facing work under your brand. In either case, we never compete for the original installation relationship — we're a support partner, not a sales channel. Pricing for ongoing aftercare is agreed based on customer volume and service level. Get in touch to discuss what you need.
