1. Centralized Transformer: Suitable for large-scale photovoltaic power plants, it centrally boosts the voltage output from multiple inverters.
2. String Transformer: Corresponds one-to-one with the inverters; small in size and high in efficiency, suitable for small and medium-sized power plants.
3. Dry-type Transformer: Offers good fire resistance and is often used in residential photovoltaic systems and rooftop power plants.
