How does a solar transformer work?

In the power system’s transmission and transform process, solar transformers played an essential role in varying the AC voltage while maintaining an AC rate constant. The transformer increases the voltage at the generator’s terminal to transmit a specific amount of power.

What is a solar transformer?

Transformers are critical components in solar energy production and distribution. Historically, transformers have ‘stepped-up’ or ‘stepped-down’ energy from non-renewable sources. There are different types of solar transformers including distribution, station, sub-station, pad mounted and grounding.

How to choose a transformer for a solar project?
