Absolutely wonderful support. I have a GivEnergy system that was installed in 2022, and a firmware update was flagged in the app, so I proceeded to update the software .... and immediately regretted it, as my inverter came up with an error, and was not working at all! With no GivEnergy support available, and my installer saying there was nothing he could do, I googled help, and found Ron. What a stroke of good luck! Submitted an on line enquiry late morning, and received phone call just after 5 pm, and later that evening Ron was able to supply me with old firmware no longer available on the GivEnergy web site. I was then able to update the firmware using a GivEnergy youtube video as reference, and hey presto the system was back up and running. One further slight adjustment by Ron and we are back normal. What a relief. I have no hesitation in recommending Solar Tech Support if you have a problem. Great service! And if you are a GivEnergy system owner, whatever you do, DO NOT UPDATE FIRMWARE!

Trade-rate diagnostics, commissioning help, and second-opinion fault-finding across every major inverter and battery brand. Talk to an engineer, not a call centre.
Get in touchRon 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)
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
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!
Ron made more sense in 20 mins than our installer has done over the last 12 months There is a jungle out there and you need someone like Ron to give a comprehensive overview and solution
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.
What's covered
Complex Fault Diagnosis
When you've exhausted your own diagnostics and the manufacturer helpdesk hasn't been useful, we review all available monitoring data, inverter error logs, battery cell data, and system configuration. Root cause identified, written report with evidence and resolution steps.
Commissioning Support
System not behaving as expected after install — battery not charging, CT clamp reading wrong, export limit not applying, EPS not switching, monitoring portal not connecting. We diagnose remotely and talk you through the fix in real time.
Firmware & Configuration Guidance
Firmware updates that change system behaviour, settings that have reverted after a reset, tariff schedule configuration for Octopus Flux or Intelligent Go, charge/discharge window setup, and battery calibration procedures. We know the inverter firmware landscape across all major brands.
Manufacturer Escalation
When the manufacturer's first-line support isn't resolving the issue, we escalate directly to technical teams. We speak their language, provide structured fault evidence they can act on, and follow up until the issue is resolved or a replacement unit is dispatched. GivEnergy is the exception: it entered administration in April 2026 and its manufacturer support has closed, so GivEnergy cases run through the available warranty channels (installer workmanship cover, IBG, Section 75, MCS Consumer Code) rather than GivEnergy support — see our GivEnergy administration page.
Common scenarios
How a diagnostic session works
You brief us on the fault
Tell us the inverter brand and model, what the customer is experiencing, any fault codes displayed, and what you've already tried. Share monitoring portal access or screenshots if available. The more context you provide, the less time we spend on triage and the faster we identify the root cause.
We analyse the system remotely
We review monitoring data, inverter event logs, battery cell voltages, firmware version, configuration settings, and historical performance patterns. We check for known issues with that specific firmware version, configuration conflicts, and manufacturer service bulletins. This is engineering-level analysis — not a checklist.
Root cause identified and reported
You receive a written diagnostic report: fault identified, root cause analysis, supporting evidence (monitoring data, error log extracts, configuration screenshots), and clear resolution steps. If the fix can be applied remotely — a configuration change, firmware update, or settings correction — we can apply it during the session with your authorisation.
Manufacturer escalation if needed
If the fault requires manufacturer intervention — a warranty replacement, firmware patch, or hardware recall — we escalate directly to the manufacturer's technical team with a structured fault report. We follow up until the issue is resolved. Our reports are accepted by all major UK inverter and battery manufacturers and are formatted to get past first-line support directly to engineering.
Why installers use this service
You're good at installing. We're good at diagnosing. When the two skills overlap there's no problem — but some faults need a specialist who has seen the same issue across hundreds of systems and knows the fix immediately.
Faster resolution, less time on site
A remote diagnostic before a revisit often identifies the root cause and the exact fix needed — meaning one targeted return visit instead of multiple. For commissioning faults, we can resolve many issues in real time while you're still on site, avoiding a callback entirely.
Cross-brand experience
Most installers specialise in one or two brands. We support all of them. When you encounter a Sunsynk fault for the first time that you've never seen on a GivEnergy, there's a good chance we've resolved it before. That cross-brand experience is the value.
Independent credibility
When a customer disputes your diagnosis, or a manufacturer rejects a warranty claim, an independent engineer's report carries weight. We provide formal reports that are accepted by all major UK manufacturers and are suitable for dispute resolution.
Confidential and discreet
Your customer never knows we were involved. We work behind the scenes — you deliver the fix, you maintain the relationship. If you need us to speak to the customer directly, we can operate under your brand or as an independent third party.
Looking for an ongoing partnership? If you want us to handle aftercare for your customer base on a regular basis — fault triage, diagnostics, maintenance — we offer structured referral and white-label arrangements. See our full installer partnership page for details.
