Find the fault before replacing parts
Arrange a structured diagnosis for an unexplained solar problem with an independent technician.
Solar systems can develop faults that aren't obvious from the ground. A homeowner may only notice that generation is lower, the inverter is behaving differently or the monitoring app no longer looks right. Fault finding is the process of narrowing those symptoms down to the component, connection or condition responsible.
This enquiry service is useful when you know something is wrong but don't yet know what needs repairing. An independent technician will look at the installation as a connected system, because a warning at one component can easily be caused by another, giving you a clearer understanding of the problem and a more informed decision about the next step.
Effective diagnosis is a process of elimination. A technician will start with the information available from the system, then check likely causes in a logical order — this may involve inverter data, visible inspections, accessible electrical checks and comparison between expected and actual behaviour.
The technician looks for system-related reasons output may be lower than expected, while also considering normal factors such as season, weather and shading.
Problems that appear and disappear can be difficult to trace. Timing, error history and operating conditions can help identify likely causes.
A poor connection or problem affecting one part of an array can reduce performance or trigger an inverter warning.
Some inverter errors indicate the system is detecting an electrical condition outside normal limits, which needs careful investigation.
If an app says the system is offline, the issue may be communications rather than generation — a technician can help establish which.
Technicians work from symptoms and test results instead of changing parts until the fault disappears.
Panels, inverters, isolators, cabling, batteries and monitoring can affect one another, so the installation is considered as a whole.
The point of fault finding isn't simply to name a problem — the technician explains what the finding means and what repair makes sense.
Describe what your solar system is doing and we'll help match you with an independent technician.
