Inverter Replacement in Sheffield
Sheffield has one of the highest densities of FiT-era solar installations in South Yorkshire — many now reaching the 10–15 year point where inverters start to fail. With All Seasons Energy going into liquidation in January 2026, a lot of Sheffield homeowners have lost their original installer. We're about 25 minutes away and carry common replacement stock for same-week scheduling.
Tell us the inverter brand and model — or send a photo of the unit. Include the fault symptoms and your Sheffield postcode. We'll confirm the replacement spec and give you a written quote.

Sheffield's solar landscape is shaped by two things: terrain and timing. The city is built across several steep valleys, which means roof orientations vary far more than in flatter cities — and installers didn't always account for that properly when sizing inverters. Most of the residential solar in Sheffield was installed during the FiT era between 2010 and 2015, primarily through council-backed schemes and national installers like All Seasons Energy. Those inverters are now 10–15 years old, which is the typical failure window for string inverters.

Roof pitch and aspect vary significantly — inverter sizing matters more here
The terrain factor matters at replacement time because it's an opportunity to correct any original sizing mismatch. If your inverter was oversized or undersized for the actual roof pitch and orientation, we flag that during the diagnostic and spec the replacement correctly. A straight like-for-like swap isn't always the right answer on Sheffield's hillside installations.
Inverters we replace most often in Sheffield
Sheffield's inverter mix skews heavily toward FiT-era string inverters, with newer hybrid and battery systems appearing in the western suburbs. Each brand has a different failure pattern and replacement path.
Galvo and Primo models dominate South Sheffield, particularly across Woodseats, Gleadless, and Heeley. These were the default on many All Seasons Energy and council scheme installs from 2011–2014. The Galvo units are now well past their expected lifespan. Typically replaced with a current hybrid inverter for battery compatibility.
Mini and 4G models from social housing retrofits across Hillsborough, Chapeltown, and Parson Cross. High volume of identical units means we carry common Solis replacement stock. The Mini series in particular has a consistent failure pattern — usually the relay or DC isolation failing after 8–10 years.
HD-Wave systems on newer installs in Ecclesall, Dore, and Totley. SolarEdge uses optimisers under each panel — a fault can sometimes be resolved at optimiser level without replacing the main inverter. A diagnostic confirms the exact fault location before we quote.
Growatt ShineWay units on systems from 2015–2018 reaching end of life across Crookes, Stannington, and Stocksbridge. GivEnergy on newer battery retrofits — faults here are often firmware or communication issues rather than hardware failure. SMA Sunny Boy on older premium installs across the western suburbs.

All Seasons Energy was based in Sheffield — and now your inverter needs replacing
All Seasons Energy went into voluntary liquidation in January 2026 after installing solar, heat pumps, and insulation across South Yorkshire for years. Sheffield was their home city, so a disproportionate number of their installations are here. Those systems are now ageing, and when the inverter fails there's nobody to call. We handle the full recovery alongside the replacement — your manufacturer warranty is separate from the installer and may still cover the hardware.

Inverter replacement in Sheffield — common questions
A standard string inverter swap in Sheffield is £795 — that covers the new unit, removal of the old one, fitting, commissioning, DNO G99 variation paperwork, and a written post-installation report.

The most frequent replacements we handle in Sheffield are Fronius Galvo units from All Seasons Energy installs and Solis Mini units from South Yorkshire council schemes.

Yes. All Seasons Energy was based in Sheffield and went into voluntary liquidation in January 2026. Many of their installations across South Yorkshire used string inverters that are now reaching end of life. Your manufacturer warranty on the inverter hardware is separate from the installer — it may still be valid. We handle the full recovery: manufacturer warranty check, MCS certificate retrieval, monitoring transfer, and the physical inverter replacement. Full All Seasons Energy guide →
It can. Sheffield is built across several steep valleys, which means roof pitch and aspect vary significantly even on the same street. Some original installations were sized without properly accounting for this. When we replace an inverter, we check the existing array configuration against the replacement spec. If the original was a poor match, a replacement is an opportunity to correct the sizing. A diagnostic confirms whether the issue is the inverter, the configuration, or both.
Sheffield sits about 25 minutes south of our base, making it one of our fastest-response areas.
