01 / SCOPEInverter fault assessment
Share the displayed fault code, model and when the issue occurs. A technician can distinguish equipment problems from wider electrical or operating conditions, then explain whether repair, manufacturer support or replacement is the appropriate next step.
02 / SCOPELow-generation investigation
Compare generation records with the system’s history and local conditions. Ask the provider to consider weather, shading, soiling, outages and equipment condition before concluding that the panels have deteriorated or that a larger system is needed.
03 / SCOPEElectrical fault diagnosis
Qualified personnel can assess wiring, connections, protective devices and related electrical equipment. Agree a clear inspection scope and safe access arrangements. Homeowners should not open equipment, handle exposed wiring or repeatedly reset a system that is tripping.
04 / SCOPEModule and string testing
Where initial findings justify it, ask about detailed tests that can help locate underperforming sections. The provider should explain why the test is needed, what evidence it produces and how that evidence informs the proposed remedy.
05 / SCOPEThermal inspection
Thermal imaging can support an investigation into abnormal heating. Ask the specialist to interpret findings alongside operating conditions and other checks, rather than treating a coloured image alone as a complete diagnosis or a reason for replacement.
06 / SCOPERepair verification and records
After authorised work, request the findings, replaced-component details and commissioning or test records relevant to the repair. Agree how restored operation will be checked and whom to contact if the same symptom appears again.
