Structure Of The Solar Transformer
The structure of solar transformers closely resembles that of
conventional transformers, consisting primarily of a tank, iron
core, windings, and bushings.However, conventional power
distribution transformers cannot be used for solar inverters due to
specific application requirements. Thus, customization is
essential, taking into account the unique nature, inverter
technology, and operational characteristics of solar power plants.
