Solar PV Transformers

Three-Phase Pad-Mounted Transformers for Solar Power Applications

Photovoltaic plants are connected to the grid via step-up transformers. Since the conditions in solar power plants are rather severe, the transformers must withstand harsh weather conditions as well as high temperatures. When designing a PV power plant, transformer sizing is critical since too large-rated transformer can result in instabilities and economic disadvantages, while too small transformer power might not fully harness the plant’s capability.


Meta-Power Solutions’ oil-immersed solar PV transformers are designed to operate in all kinds of environmental conditions. These liquid-filled transformers are rated based on the size of the solar generation capacity and the voltage class of the collection array, complying with all applicable standards (ANSI/IEEE) as well as being energy efficient.

MPS solar transformers are designed for solar PV medium-voltage applications. These pad-mounted transformers are environmentally friendly because they use biodegradable and sustainable FR3 dielectric fluid, which offers greater fire protection and a longer lifespan. With ratings ranging from 45 to 12,000 kVA, these solar transformers can be customized to include a wide range of site-specific features to optimize safety and system interoperability.
