    What is the purpose / component name to the single winding connected in series (separate to the primary and secondary windings) with my transformer in a 2.5kw solar inverter?

    Transformers sometimes have a small extra winding to allow a 5 or 10 volt variation in the output voltage.

    Alternatively there is a type of transformer that has a control winding to stabilise the output voltage. In this case you drive a signal, derived from the output, through the winding to vary the permeability of the core and thus linkage between primary and secondary.

    If your kit is not connected and the handbook makes no mention you may safely ignore the winding. It may be they makers use the same transformer in different models, some using the winding, some not. Or they may simply have purchased an off the shelf transformer and not used this particular feature.
