Solar faults we diagnose and repair
When a solar PV system stops generating, displays a warning or produces less energy than expected, the visible symptom may not reveal the real fault. Fix My Solar provides structured diagnostics and repairs for existing residential and commercial systems across Ireland, including systems installed by other companies. We work on solar PV electricity systems, including inverters and batteries. We do not service solar thermal or hot water systems.
- Inverter warning codes, shutdowns and grid errors.
- Solar batteries not charging, discharging or communicating.
- Unexpected loss of generation or low system output.
- Loose, damaged or incorrectly configured wiring.
- DC string, connector and isolation faults.
- Hybrid inverter and battery communication errors.
- Faulty fuses, breakers, isolators or surge protection.
- Monitoring, meter and data-connection problems.
Diagnosis first, then a clear solution
System-Level Diagnosis
We test the connected system to identify whether the fault is in the inverter, battery, wiring, protection or configuration.
Prepared Assessment
Send the equipment model, error code, photographs and Eircode so we can prepare for the diagnosis.
Transparent Pricing
We explain the findings, available options and cost before repair or replacement work begins.
Suitable Components
Where components are replaced, suitability depends on the electrical design, installed equipment and manufacturer requirements.
Independent Support
We assess existing systems even when the original installer is unavailable, subject to equipment access and manufacturer support.
Documented Next Step
You receive a practical explanation of the fault and the recommended repair, replacement or manufacturer route.
Choose the right solar PV repair service
This page covers complete PV-system fault finding. For a more specific problem, use the dedicated service page so that we can collect the right information before the assessment.
Solar inverter repair
For shutdowns, warning codes, grid errors, isolation faults, missing generation and inverter communication problems.
Solar battery fault diagnosis
For batteries that are offline, not charging, not discharging or reporting hybrid-inverter and communication errors.
Wiring and protection faults
For damaged connectors, DC string issues, isolator faults, surge protection, breakers and other electrical problems affecting safe operation.
Monitoring and unexplained underperformance
For missing production data, meter discrepancies and systems that appear to generate less energy without a clear equipment warning. See our solar PV maintenance service for regular checks.
What happens after you contact us?
We first collect the system type, equipment models, error messages, monitoring screenshots and Eircode. Remote evidence may identify the likely area of the fault, but electrical conditions usually require on-site testing. After diagnosis, we explain what was found and provide the next appropriate option before further work proceeds.
Do not open an inverter, battery or electrical enclosure. If equipment is hot, damaged, producing a burning smell or behaving unusually, keep clear and follow the manufacturer’s safety instructions while arranging qualified assistance.
