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.
