Transformer in Solar Power Plant Solutions

Our advanced transformer for Solar Power Plants delivers reliable, efficient, and high-performance power transmission tailored specifically for renewable energy generation in photovoltaic (PV) systems. Designed to meet the unique demands of solar applications, these specialized solar power plant transformers (often called inverter duty transformers or step-up transformers) play a critical role in utility-scale and commercial solar installations. They efficiently step up the low-voltage AC output from inverters (typically 400V–800V) to medium or high voltages (such as 11kV, 33kV, or higher), enabling seamless grid integration while minimizing energy losses over long-distance transmission.

Cases Study of Transformer Used in Solar Power Plant Solutions

Photovoltaic Power Station-35kv Box-Type Substation

Huawan's solar panel transformer substations are applied in centralized PV plants, converting and distributing solar energy to ensure stable operation and reliable power transmission. They transform low voltage from inverters to medium-high voltage (e.g., 0.69kV to 22kV) with 6% impedance to suppress harmonics, ensuring grid stability.

Photovoltaic Power Stations - Step-Up Transformersion

For photovoltaic systems, Huawan, as a leading pad mounted transformer factory, provides step-up transformers and box-type transformers to connect PV modules to the grid, supporting voltage conversion in distributed PV projects. This transformer for solar panels adopts YNd11 vector group and electrostatic shielding (copper foil grounding) to isolate windings, mitigating dv/dt transients (500V/μs) from inverter PWM outputs.

Photovoltaic Power Station - 220kv Oil-Immersed Transformer

The main transformers of Huawan are used in renewable power plants to step up the low voltage generated by solar panels, reducing transmission losses and improving the efficiency of the entire power system. The transformer for solar power plant boosts PV array voltage (e.g., 690V to 22kV) via 800kVA-3500kVA rating, using KNAN cooling and vegetable-based oil for efficient heat dissipation and 30-year design life.
