Identifying components within an inverter

Bigbazsparky
Good afternoon everyone,


In my recent spare time i have been stripping down a solar PV inverter to better understand how it operates and performs. So far i have identified most of the components and what they do, however i have discovered some quite large components that i believe could be a type of choke. They are not mounted on the PCB`s.

Can anyone offer me any advice on what these components do within the inverters and are they a perishable part. They look very robust.

The inverter I have been looking at is a small single phase domestic unit of 3.6kW.


Many thanks

Barry

    If you can upload a photo - the forum will let you do this- it is the icon that looks rather like a patients temperature chart next to the grining face on the left, and then on the window that opens, you need the second tab 'upload' - I am very happy to talk you through whatever it is  if I can . - I have been designing electronics since the last century, so can probably advise ;-)


    There will be inductors, both for EMC, and as part of the inverter proper.
