Describe the fault — error codes, display messages, generation figures. We review your monitoring data before the visit so the engineer arrives prepared.
Book a repairDiagnose first — free if we can't fixRon was Absolute God send . After 6 months of nightmares with the installer who messed up in every single aspect of the install... Ron came investigate and provide me with a detailed report and standing behind his words for my case His knowledge and understanding are simply exceptional. I can not express how happy I am to have the luck to deal with him
Particularly useful in helping to fix my GivEnergy All in One system with a disabling fault.
My 3-year old GivEnergy Solar/Inverter/Batteries installation went down with all generated electricity going to the grid and absolutely no help available from the Administrators! Thankfully, I found Solar Tech Support and Ron, who used to be a GivEnergy installer. His knowledge and ability are phenomenal and he sorted everything out remotely. I cannot recommend him more highly and a really pleasant guy to deal with! Very many thanks Ron!!
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!
After recently changing my fuse board the ct clamp broke, this meant my inverter was not communicating properly with my GivEnergy system. After several people letting me down, finally got put in touch with Ron. He came out within 24hours & resolved the fault within an hour, no fuse just got on with it. Work was tidy & arrived when he said he would. Ron followed up a few days later to confirm all was still good, great service from all involved.
Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.
Wakefield's housing stock drives its fault profile. Coalfield-era semis in Castleford, Pontefract, and Normanton tend to have compact roof arrays with ageing string inverters. Larger detached properties in Ossett and Horbury are more likely to run hybrid inverters with battery storage. Here's what breaks down and why.
The single most common repair in the Wakefield district. Mark Group installed thousands of 2–4kW systems on suburban semis between 2012 and 2015, almost all using Fronius IG or Solis Mini string inverters. At 10–14 years old, these units are failing — blank displays, recurring fault codes, or simply producing nothing. The panels are fine; the inverter has worn out. Replacement from £995 including commissioning.
GivEnergy is the dominant battery brand across the Wakefield district. Common complaints: battery draining to grid overnight, not charging from solar during the day, or charge schedules not matching tariff rates. Usually a configuration issue — reversed CT clamp, eco mode disabled, or a firmware update that reset schedules. We diagnose and resolve most of these remotely — £125 only if we fix it.
Wakefield's coalfield housing stock dates mostly from the 1960s–80s, and solar installations on these properties often involved routing cables through loft spaces with poor ventilation. After a decade, DC isolators degrade, MC4 connectors corrode, and junction boxes develop water ingress. These are safety-critical faults that need on-site inspection and replacement.
Homeowners notice their system producing less than it used to but there's no error code or flashing light. In Wakefield this is often caused by tree growth creating new shading on south-facing roofs, a failed bypass diode reducing string output, or an MPPT tracker degrading inside the inverter. We compare actual yield against expected output for the array size and orientation to identify the cause.

Monitoring review, fault identification, written report. Credited if you proceed to on-site repair.
Typically up to £495. Component replacement, wiring repair, isolator swap, connector refit. Quote before work starts.
New unit supplied, installed, and commissioned. The most common major repair on older Wakefield systems.
Full system check, generation benchmark, isolator inspection, firmware update. Details →
All prices include labour. No call-out fee for Wakefield — it's core coverage. Cost confirmed in writing before any work begins. Full pricing breakdown →
We follow the same process for every repair. No wasted trips, no surprise invoices, and the engineer arrives already knowing what's likely wrong.
Tell us what you're seeing — error codes, flashing lights, no generation, battery not charging, monitoring offline. Include photos of the display if you can. The more detail, the faster the diagnosis.
We access your monitoring portal, review generation history, analyse charge and discharge patterns, and check firmware versions. This identifies the fault in most cases and tells us exactly what parts or tools the engineer needs to bring. If the fault is configuration-only, we fix it remotely and you don't need a visit.
If an on-site visit is needed, we confirm the cost in writing before booking. The quote covers labour, parts, and commissioning. The remote diagnostic is free and the repair is quoted up front. You approve the quote before we schedule the visit.
The engineer arrives with the right parts. Wakefield is 25 minutes from our Leeds base, so urgent faults get a one to two working day response. The repair is completed, the system is tested, monitoring is verified live, and you receive a written report covering what was done and what to watch for.
Every town in the Wakefield district is within our core zone. No additional travel charges, same response times throughout. If you're not sure whether we cover your area, we almost certainly do.

Mark Group was the dominant solar installer in the Wakefield district, fitting thousands of 2–4kW systems through government energy efficiency programmes before going into administration in 2015. A decade later, these systems are reaching the age where inverters fail, DC isolators degrade, and monitoring connections drop. We pick up where they left off — diagnosis, repair, inverter replacement, and ongoing maintenance on every system they installed.
Wakefield has one of the widest brand mixes in West Yorkshire. Government scheme installs used Fronius and Solis. Private installs added SolarEdge, Growatt, and Sunsynk. Battery retrofits are overwhelmingly GivEnergy. We carry diagnostic equipment for all of them.

Inverter replacement →Yearly system health check — generation benchmarking, inverter diagnostics, wiring inspection, firmware updates. Written report. From £195.
Annual maintenance →Battery backup wiring for power cuts. Many GivEnergy systems in Wakefield have batteries installed but no EPS circuit — the battery won't help during an outage until it's wired.
