HELIOS ELECTRICAL GROUP
Solar fault finding, repairs and system health checks for systems that are underperforming, showing faults or have stopped working.
Helios Electrical Group diagnoses solar faults across Adelaide, from inverter errors and monitoring issues through to wiring faults, water ingress, damaged components and unexplained drops in system performance.
Request a Solar InspectionFIND THE FAULT FIRST
A solar fault does not automatically mean the entire system needs replacing. We inspect and test the installation, identify what is actually wrong and explain the practical options before further work is recommended.
SOLAR FAULT FINDING
A system may still appear to be operating while producing less energy than expected, losing monitoring data or developing intermittent electrical faults.
Other systems stop completely and display an inverter error, trip electrical protection or fail after weather, equipment deterioration or component failure.
Helios approaches solar repairs as an electrical fault finding job first. We inspect, test and work through the system before explaining what has been found and what repair options make sense.
The system is inspected and tested before repair or replacement work is recommended.
We explain the fault and the practical options available for the existing system.
Replacement is recommended where it makes sense, not simply because a fault has appeared.
COMMON SOLAR FAULTS
Inverter errors can be caused by the inverter itself or by another issue elsewhere in the solar installation.
A noticeable change in production can indicate a system fault or another issue affecting solar output.
Sometimes the solar system is operating but the monitoring platform is not displaying the information correctly.
Solar equipment is exposed to heat, weather and changing conditions over many years of operation.
SIGNS OF A PROBLEM
Some solar faults are obvious. Others show up gradually through lower production, intermittent inverter errors or monitoring that no longer reflects what the system is actually doing.
If something has changed without a clear reason, it is worth investigating rather than assuming the system is operating normally.
The inverter is displaying a warning, fault code or abnormal operating status.
The system appears to have stopped generating solar energy.
Solar output is noticeably lower than expected without an obvious explanation.
The monitoring app has stopped updating or no longer shows the expected data.
Solar related electrical protection is tripping or will not remain on.
Equipment shows signs of weather damage, heat, corrosion, water ingress or deterioration.
REPAIR OR REPLACE?
Some faults can be repaired by replacing a failed component, correcting wiring or connection issues, repairing monitoring or replacing an inverter.
Other systems may be old enough that replacement or a larger upgrade becomes more practical than continuing to repair ageing equipment.
We look at the condition of the existing installation, the fault itself and the longer term value of the available options before making a recommendation.
SYSTEM HEALTH CHECKS
We can inspect the accessible solar equipment and look for visible signs of deterioration, damage or electrical issues.
Available system information can be reviewed alongside electrical testing to help determine whether the installation is operating as expected.
If an issue is identified, we explain what has been found and whether repair, monitoring or further work is recommended.
OUR REPAIR PROCESS
We inspect the solar installation, review the reported symptoms and carry out suitable electrical and system testing.
Once the likely fault is identified, we explain the findings and the practical repair or replacement options.
Approved repairs are completed and the system is retested to confirm operation before the job is finished.
COMMON QUESTIONS
A solar system can stop operating for many reasons, including inverter faults, electrical protection issues, wiring problems, damaged components, grid related faults or equipment deterioration. Testing is normally required to determine the actual cause.
Changes in weather and seasonal conditions can affect solar production, but a sustained or unexplained reduction may also indicate a fault, panel issue, string problem, inverter issue or another change within the installation.
Not always. Some inverter errors are caused by conditions elsewhere in the solar or electrical installation. The error and system should be tested before assuming the inverter itself has failed.
In many situations an inverter can be replaced while the existing solar panels remain in service, provided the existing system and replacement equipment are suitable. The installation needs to be assessed before the replacement is selected.
Monitoring problems can be caused by communications, internet connectivity, configuration, meters, CTs or other monitoring equipment. In some cases the solar system continues operating normally even though the monitoring platform is no longer displaying the correct information.
Yes. Solar equipment is exposed to outdoor conditions and water ingress or corrosion can affect isolators, connections, enclosures and other electrical components.
Yes. If there are signs of damage or the system has changed behaviour after severe weather, the installation can be inspected and tested to determine whether further repair work is required.
It depends on the age of the system, the component that has failed, the condition of the remaining equipment and the cost and availability of compatible repairs. We assess the existing system before recommending the most practical option.
Yes. A solar system can be inspected and tested where there are concerns about performance, ageing equipment or unexplained changes in operation.
Helios Electrical Group provides solar fault finding and repairs across Adelaide and surrounding suburbs. Send through your suburb, inverter model, any fault code and screenshots or photos where available and we can assess the next step.
Send through the inverter model, fault code, photos or monitoring screenshots and tell us what the system is doing.
