Solar & Renewable DiagnosticsNorth Wales

When a system isn't working as expected, you don't need guesswork — you need proper fault finding. I diagnose solar PV, battery storage, monitoring/app issues and smart energy systems (including systems installed by other companies).

Tip: If you can, include your inverter/battery make & model, any error code, and your postcode.

What I diagnose and troubleshoot

Focused on the real-world problems people call about — especially after an installer has disappeared.

Solar generation seems low

We check strings, isolators, inverter status, and monitoring data to confirm whether its a genuine performance issue or a readings/config problem.

Battery stopped charging / discharging

Often caused by settings, CT clamp direction/placement, export limits, comms faults, or a genuine battery/inverter issue. Well identify the root cause.

The app stopped working

We sort monitoring and connectivity issues  WiFi, dongles, portal accounts, and data not updating.

Installer disappeared

If youve been left with a system no one will touch, I can take over diagnostics and get it working safely and correctly.

Common systems

  • SolaX
  • Solis
  • Tigo
  • Common monitoring portals
  • Hybrid inverters & battery storage

FAQ

Straight answers to the questions people ask before booking diagnostics.

Do you work on systems installed by other companies?

Yes. A lot of my diagnostic work is on systems installed by someone else  including cases where the installer has disappeared or wont come back.

Can you fix monitoring and app issues?

Yes. If the app has stopped updating, the WiFi has changed, or the portal account setup is a mess, I can get monitoring stable again and explain what youre looking at.

My battery isnt charging  is it always a faulty battery?

Not always. Its often a CT clamp/export or settings issue. Ill test and confirm whats actually wrong before recommending parts.

Do you do general electrical work as well?

Yes  Im a qualified electrician and still do general electrical work across North Wales and West England. Diagnostics is my premium specialist service.

What areas do you cover?

North Wales primarily, and West England for the right jobs. If youre unsure, message your postcode and a quick description of the issue.
