Inverter Problems Solved, Fast
The UK's Feed-in Tariff solar boom of 2010-2015 installed hundreds of thousands of solar systems. Those inverters are now reaching the end of their 10-15 year design life. If your generation has dropped, your display is showing error codes, or your system has stopped entirely, the inverter is the most likely culprit. We've replaced more inverters than we can count — and we've learned which failures are simple fixes and which mean the unit is dying. We carry the most common replacement models on our vehicles, so most residential systems are back generating on the day we arrive. And when you're replacing anyway, we'll show you the numbers on upgrading to a battery-ready hybrid.

Why Choose Our Inverter Replacement Service
Upgrade to Battery-Ready
When you're replacing your inverter anyway, upgrading to a hybrid inverter adds just £200-400 to the cost — and makes your system battery-ready without any additional electrical work.
FiT Orphan Support
If your original installer has gone bust, your inverter warranty may still be valid with the manufacturer. We help FiT-era system owners navigate warranty claims directly with SMA, Fronius, SolarEdge and others.
All Brands Covered
We replace every inverter brand and model installed in the UK: SMA, Fronius, SolarEdge, Enphase, Growatt, GivEnergy, Fox ESS, SunSynk, Huawei, and more.
Like-for-Like or Better
We can replace your existing inverter like-for-like, or use the opportunity to upgrade to optimisers, microinverters, or a hybrid unit — improving shading tolerance and future-proofing your system.
Same-Day Replacement
We carry the most common replacement inverters on our vehicles. For most residential systems, we can restore your generation the same day we diagnose the fault.
FiT Payments Unaffected
Replacing your inverter doesn't affect your Feed-in Tariff payments. FiT is tied to your MCS certificate and generation meter — not the inverter brand or model.
How It Works
Remote Diagnosis
We review your monitoring data and error codes remotely before visiting — often confirming the inverter diagnosis without needing to come out first.
On-Site Assessment
We test the inverter and connected panels to confirm the fault and check panel string voltage and current are within spec for the proposed replacement unit.
Replacement Installation
We disconnect the failed unit, install the replacement, update cabling and AC connections as needed, and commission the new inverter to the panel array.
Monitoring & Verification
We configure monitoring on the new inverter, verify generation output matches expected performance, and provide you with updated documentation.
Frequently Asked Questions
Warning signs include: persistent red or amber indicator lights, error codes on the display, complete shutdown with no lights, reduced generation compared to your monitoring history (especially year-on-year comparison), buzzing or clicking noises, or the inverter getting unusually hot. Some failures are intermittent — the inverter restarts but fails again at peak generation.
