Had a fault on a GivEnergy AC coupled 3kW home battery and was getting no joy from multiple companies I contacted, as well as the original installer. Contacted Solar Tech Support and they sorted it really quickly, now working perfectly again, can’t recommend them highly enough, professional and very responsive!
Ronald at Solar Tech Support was very quick and knowledgeable in helping me restart my GivEnergy solar electric battery. I would highly recommend his services.
Had issues with 10yr+ installation. 1 inverter going into alarm mode, unable to access monitoring apps and wanted someone to review and document worthiness of the 2 systems I have. As you will find with older systems, the original installers have moved on, other companies only want to replace and install new, or make up silly prices as they don't want the work, so struggling for 18 month plus trying to source someone to do this. Ronald managed to fit me in the day after contact as he was in the area. Spent a couple of hours on site, found issue with the inverter alarm and he monitoring this to find a total solution, got me back onto the monitoring apps, provided a report on the installations and identified potential areas of concern. These are the people you need for diagnostic reviews of your installations, long term industry professionals, who have a wealth of knowledge gained through working in the industry, know the differing systems and how to contact and approah the companies involved. These are the people you need if you are having issues with installers and / or product and/or supply companies.
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
Called spoke to Ron. Was very informative and more importantly listen to the issues regarding my system. Was very professional and tackled the problem and had my system back on it's way. Thank you once again Ron
Cannot say enough how impressed I have been with Ronald at Solar Tech Support. When faced with not sure what to do next, I was recommended his services via a GivEnergy Community Group. Within an hour my system was back up and running again. Phew!!
The Mansfield and Ashfield area has one of the highest concentrations of government-funded solar installations in the East Midlands. ECO, Green Deal, and local authority energy efficiency programmes targeted the district's 1930s–1970s housing stock heavily — the same pattern we see across the former coalfield communities in South Yorkshire. The systems are now 10–14 years old and the inverters are failing at scale.
Mansfield, Sutton-in-Ashfield, and Kirkby-in-Ashfield are dominated by 1930s–1970s semis and terraces built during the mining era. Uniform roof pitches and south-facing orientations made them ideal candidates for bulk solar installations. Most systems are 2–4kW arrays with single string inverters — fitted quickly as part of government programme rollouts. The panels are typically fine, but the inverters are past their design life.
Installations through ECO, Green Deal, and council-backed programmes were done at volume by national companies — many of which have since closed. Homeowners were often given minimal paperwork, monitoring was never set up, and warranty documentation was sparse. When the inverter fails a decade later, there's no one to call and no record of what's actually on the roof. We identify the hardware, rebuild the documentation trail, and check manufacturer warranties.
Mansfield is at the edge of our on-site coverage — about 90 minutes from our Yorkshire base. For most faults, a free remote diagnostic is the smartest first move. We analyse monitoring data (or generation meter readings if there's no monitoring), identify the fault remotely, and arrive on-site already knowing what parts to bring and how long the job will take. Nothing is wasted — no speculative visits, no return trips for parts.
If you're familiar with what we do in Barnsley and Rotherham, the Mansfield picture is near-identical. Former coalfield communities, government scheme installations, the same brands and inverter models, the same failure timeline. The only difference is the drive time — we know exactly what to expect before we arrive.
Mansfield is on our scheduled route into the East Midlands. Every job starts with a remote diagnostic — we review your monitoring data, fault codes, and generation history before booking the visit. No call-out fees. Pricing confirmed in writing before any work.
On-site fault diagnosis — inverter failures, generation drops, DC isolator faults, panel issues, battery errors. From £295.
Fault diagnosis →Complete replacement — old inverter removed, new one installed, configured, and generation verified. All common brands. From £995.
Inverter replacement →An EPS circuit turns your existing battery into genuine backup power. We wire a dedicated circuit so essentials stay on during outages — lights, fridge, router.
EPS installation →Annual health check — performance audit against expected generation, inverter diagnostics, wiring inspection, firmware updates. Written condition report. From £195.
Annual maintenance →Bought a Mansfield property with solar? We identify the system, check generation history, set up monitoring on your phone, and deliver a written report with recommendations. From £295.
On-site walk-through →Remote system analysis — monitoring review, fault log check, firmware assessment. Written report usually within 24 hours. Free — £125 only if we fix it remotely.
Remote diagnostic →Mansfield's solar landscape is dominated by government scheme installs from the early 2010s. The problems are consistent and predictable — the same faults we see across the former coalfield communities of South Yorkshire and the East Midlands.
The single most common fault. Budget string inverters fitted during ECO and Green Deal rollouts have a practical lifespan of 10–15 years. Across Mansfield, Sutton-in-Ashfield, and Kirkby-in-Ashfield, these units are now failing in large numbers. The inverter display goes blank, generation stops, or recurring fault codes appear. The panels themselves typically last 25+ years — replacement with a modern hybrid inverter restores generation and your FiT payments continue unaffected. Inverter replacement →
Government scheme installations were done at speed and scale. Monitoring was rarely set up, MCS certificates were handed over in envelopes that got lost, and warranty registration was left to the homeowner. A decade later, the system has been generating quietly with no one checking whether it's performing properly. We see Mansfield systems that have been running at 60–70% capacity for years because a partial string fault went undetected. A free remote diagnostic catches this. System underperforming guide →
Rooftop DC isolators fitted on early government scheme installations are a known weak point across the industry. Water ingress, UV degradation, and arcing damage the switch mechanism over time. A faulty DC isolator can prevent safe shutdown of the system and is a potential fire risk. If your isolator switch feels stiff, has visible burn marks, or won't turn cleanly, it needs replacing. We carry the most common replacements and can usually swap them during the same visit as an inverter replacement. Fault diagnosis →
When a string inverter dies, generation stops and the FiT generation meter stops counting. Homeowners worry that replacing the inverter will affect their tariff registration or that they've lost payments permanently. Neither is true — your FiT contract is with the energy supplier and survives an inverter swap. Payments resume as soon as the new unit is generating. We handle the meter readings and can advise on whether your export rate needs updating after the replacement. FiT payments stopped →
The national companies that installed solar across the Mansfield area through government energy efficiency schemes have had a high failure rate. Several have gone into administration or been dissolved, leaving homeowners with systems but no support. Your manufacturer warranties are usually still valid, so you just need someone independent to take over support. Two exceptions: GivEnergy Ltd entered administration on 9 April 2026 and no further hardware warranties will be honoured (GivEnergy warranty guide), and Fox ESS claims go through a Local Installer, a role we can take on (Fox ESS warranty guide).
Administration 2015. Leicester-based but installed thousands of systems across the East Midlands through government programmes. Fronius inverters now 10+ years old.
Mark Group guide →Dissolved February 2022. Wales-based but installed across northern England and the Midlands including Mansfield district properties.
Solar Plants guide →Dissolved November 2023. Combined energy supplier and solar installer. 7,500+ customers nationally — some Nottinghamshire properties affected.
Solarplicity guide →Installer not listed? The recovery process is the same regardless of who installed your system. Full installer gone bust guide or book a call.
Mansfield's solar brand mix is almost entirely FiT-era. Fronius IG and IG Plus units dominate Mark Group installs. Budget Solis and Growatt string inverters appear on ECO scheme systems. Battery retrofits are starting to appear but the area is still predominantly simple panel-and-inverter setups. We support every brand — old and new.

Mansfield has a high density of solar-equipped properties changing hands, and the documentation almost never follows. The original installer has likely closed. Monitoring was never set up. The FiT payments might still be registered to the previous owner. We visit, identify every component, check the system is generating properly, set up monitoring in your name, verify what's still under warranty, and hand over a written report covering everything.
Describe the fault — what you're seeing (or not seeing), the brand if you know it, when it started. We'll come back with a clear plan and price, usually same day. A remote diagnostic is often the smartest first step for Mansfield — it identifies the fault before we travel.
