Introduction to autotransformer
Among the many types of transformers, there is a special transformer in which the primary and secondary coils are directly connected in series with the same winding. This self-coupling structure gives these transformers the name autotransformers.

The role of isolation transformer in photovoltaic system
Isolation transformers are widely used and have the title of "safe power supply". It has large-scale applications in machine tools, lighting, medical and other fields. Today we will introduce the role of isolation transformer in photovoltaic system.
The role of step-up transformer in photovoltaic power generation system
Unlike traditional power generation methods, photovoltaic power generation has peak-valley cycle characteristics. That is, it generates electricity during the day and stops working at night, which is not as stable as traditional power generation. Therefore, in photovoltaic power generation systems, photovoltaic transformers are used to connect them to the power grid, and in this way, electricity is transmitted to the power grid.
The capacity of the transformer should be greater than the power of the photovoltaic panel? Why
Usually, when recommending the capacity of the transformer to the photovoltaic panel customer, it is recommended to use a larger capacity transformer. That is: for an 800KW photovoltaic panel, a 1000KVA transformer is recommended. Do you know why?
