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!

Takeover pricing

Baseline audit + handover
from £895

One-off onboarding fee. Includes on-site audit, documentation recovery, monitoring transfer, written baseline report.

Larger / medium system
from £895

For 50–150 kW commercial systems where the audit needs a full day on-site and more involved documentation work.

Ongoing care
No-fix-no-fee

After handover, fault response uses the standard rate-card — free remote triage, ${PRICES.EM_01.fromText} on-site callout. No locked-in retainer.

When you need a system takeover
Previous installer gone bust

The most common takeover scenario. Monitoring locked, no warranty contact, orphaned documentation. We handle the full recovery: documentation rebuild, monitoring access transfer, and a clean technical baseline.

Switching maintenance provider

Current O&M arrangement is too expensive, too slow, or too commercially conflicted. We can baseline the system while your current contract is still active — no gap in coverage during the transition.

Building acquisition / new lease

You've just bought or leased a commercial property with existing solar. You need to know what condition it's in, who looks after it, and what the maintenance commitments are. The takeover handover gives you a clear technical and contractual reset.

No existing arrangement

System was installed and then forgotten about — common with FIT-era commercial installs where the installer never offered ongoing maintenance. We build the maintenance regime from scratch.

Insurance / compliance requirement

Your insurer or facilities-management contract now requires named technical oversight on the solar installation. The takeover engagement gives you a documented commercial relationship with an independent provider — no manufacturer or installer conflicts.

Multi-site portfolio

Property management company with solar across multiple sites and inconsistent maintenance histories. We onboard the whole portfolio with a single baseline-audit cycle and consistent technical records across all sites.

How the takeover works — 6 steps

1
Free scoping call

You tell us where the system is, approximate size, brand if known, and why you're looking for a takeover. 15 minutes by phone or video. We confirm whether we can take it on and what the baseline-audit fee will be.

2
Written quote

Fixed-price baseline audit + handover scope, in writing. Larger systems get a bespoke scoping document. You commit before we schedule the on-site work.

3
On-site baseline audit

Full inspection: inverters, panels, cabling, isolators, battery storage where present, monitoring hardware, DNO connection. Components identified, wiring verified, faults catalogued. Half a day for small systems, a full day for larger.

4
Documentation recovery

We chase whatever paperwork we can: original commissioning certificates, MCS/RECC records, DNO connection agreements, FIT or SEG paperwork, warranty status. Where records are gone, we reconstruct from on-site evidence.

5
Monitoring handover

Portal access transferred to STS, alerting reconfigured to come to us, historical performance data exported and stored. If the original installer locked the portal, we work with the manufacturer to re-establish access.

6
Baseline report + ongoing care

Written baseline report covers system condition, all faults found, remediation quote (if any), and the documentation file. Then the system is under our care — ongoing fault response uses the standard no-fix-no-fee rate-card. No retainer.

FAQ

System takeover — frequently asked questions

A system takeover begins with a baseline audit — a full on-site inspection of your commercial solar system to assess current condition, identify faults, verify monitoring status, and recover or reconstruct documentation. We then remediate any immediate issues, configure monitoring under our care, and establish a documented baseline to measure future performance against. The baseline-audit fee is from £895; remedial work is quoted separately.
Yes. This is the single most common reason commercial clients contact us for a takeover. When the original installer is no longer trading, documentation is often missing, monitoring may have lapsed, and warranty claims become more difficult to pursue. We assess the system independently, recover what documentation we can, and establish a new technical baseline. We are not tied to any installer network — we take over any commercial solar system regardless of who installed it.
That depends on your existing contract terms. Review your current agreement for notice periods, termination clauses, and any handover obligations. We can conduct the baseline audit while your existing contract is still active — so there is no gap in coverage — and coordinate the transition to minimise disruption.
Missing documentation is common, particularly for older installations or where the original installer is no longer trading. Our engineers assess the system on site, identify all components, verify wiring configurations, check DNO connection agreements, and reconstruct a working system record. This baseline documentation becomes the technical reference for everything that follows.
The baseline audit is typically completed in a single site visit (half-day for small systems, full day for medium-to-large). Monitoring setup, documentation recovery, and any immediate fault remediation may take one to two weeks depending on system complexity and the availability of existing records. Once the baseline is established, the system is under our care immediately.
Yes. The baseline audit identifies all existing faults and underperformance. We provide a clear remediation plan with fixed pricing for any repair work needed before the system is fully under our care. You know exactly what condition the system is in and what it will cost to bring it up to standard. There is no obligation to carry out remediation through us — you can use the audit report independently if you prefer.
No-fix-no-fee remote diagnostic for any fault; same emergency-callout rates as the consumer side; written reports after every visit. We hold the documentation and monitoring access so when something happens, we already know the system. No locked-in retainer or surprise fees — same transparent rate-card as everything else on this site.
Baseline audit + documentation handover: from £895 one-off. Larger or multi-site systems quoted bespoke after a free scoping call. Any remedial work uncovered during the audit is quoted separately in writing — no surprise invoices. Ongoing fault response uses the same rate-card as the consumer site (free no-fix-no-fee remote, from £295 on-site callout).
