Report a fault nowBrilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.
My Givenergy system went offline, so I lost control of it. Ron from STS and Craig from Norfolk Solar were most helpful in diagnosing the problem by phone. Full marks for their patience and ability.
We decided to treat ourselves to an upgrade to our existing solar system, and after a little searching, it became evident that Ron and his team provide the service and support we required. Decommissioning and recommissioning our new SunSynk Acure inverter and a wall-mounted Fogstar battery (which is of substantial size and weight compared to the original) was completed swiftly and competently. The installation was perfectly executed, and all upgraded paperwork for the increased battery export capacity was handled by Ron. I have no hesitation in recommending this team of support technicians to you.
My issue was assessed and resolved quickly once the engineer was able to look at the problem. This took a little longer than I had expected (3 days) and keeping the PC on all day/everyday with Sentinel open was a little cumbersome I thought. That said, with little support coming from GivEnergy nowadays it was good to find someone who knew the platform and could resolve my issue.
Brilliant service from Ron - our GivEnergy inverter stopped working on Tuesday what a nightmare seen as the company who installed it are no longer in business. Through social media I found STS (Ron) he had a new inverter and it was fitted and working by Friday - what I thought was going to be a nightmare turned out not to be!!! Great guy great company - def my go to now for anything solar related - Thank you so much
I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.
Free if we can't fix it remotely. If we do fix it remotely, you pay the remote-fix rate only.
Business-hours emergency callout — diagnosis + scope of any larger remedial work.
Weekend, evening or confirmed-safety same-day attendance.
Fitting for commercial three-phase and central inverter replacement. Part sourced separately at cost.
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.
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.
System reporting stopped — data gaps, inverter communication lost, sensors showing stale readings. Often resolvable remotely via a firmware reset or CT clamp recalibration; if the logger needs reconnecting to the site network, we do that on site.
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.
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 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.
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.
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.
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.
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.
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.
From our Yorkshire base we attend commercial sites across Leeds and West Yorkshire, Wakefield and the Five Towns, and the Barnsley district. Remote triage is available nationwide.
Tell us what's happening and we triage same day. Free no-fix-no-fee on the remote diagnostic; on-site quoted before we attend.
Due to unprecedented demand we’re currently only carrying out on-site work in Yorkshire, and replies are taking up to 7 days. Remote diagnostics continue for the whole UK as normal.
Every message is read and answered, so please don’t send it twice; that only slows the queue.
