Solar inverter fault support
Have an inverter error or no generation?

The inverter converts the electricity your panels produce into power the property can use. When it develops a problem, the whole installation can appear to stop working, even though the panels are still capable of generating.
Solar Panel Repair Dorset takes enquiries about warning lights, error codes, repeated shutdowns and unexplained loss of output. An error message is a useful clue, but it doesn't always mean the inverter is at fault, so the independent technician who responds looks at the wider system before recommending repair or replacement.

The right response depends on the inverter, its age, the displayed fault and what testing shows. Some issues originate elsewhere in the solar installation, making diagnosis important.
Note the exact message or code when you enquire. It can help narrow the investigation, although testing may still be needed to establish the underlying cause.
A blank or apparently dead inverter can have several causes. A technician investigates the system rather than assuming immediately that a replacement inverter is required.
An inverter that repeatedly disconnects may be responding to conditions elsewhere in the installation. Methodical testing helps distinguish equipment faults from wider system issues.
Older inverters can eventually fail while the panels still have useful service life. A technician can assess the situation and explain whether further repair or replacement is the practical choice.

An inverter error can be a symptom of another issue, so the inverter shouldn't automatically be blamed.
Where an inverter is ageing or uneconomical to repair, the technician can explain that rather than pursuing unnecessary work.
Include the inverter's make and approximate age if you know them. Parts availability for older models affects whether repair is practical.
Make a note of any inverter message or error code and include it when you contact us.
