Solar Step Up Transformer

Solar transformers are crucial for converting solar energy into electricity, The main function of the solar step-up transformer is to increase the voltage level of the solar inverter output so that the power can be effectively transmitted to the grid.

WINLEY's solar step up pad mounted transformers is at the forefront of the evolution and new trends in the renewable energy transformer market.

Unique demands of solar applications

Integrating renewable energy sources like solar introduces unique challenges for transformers. The cyclical nature of the source can lead to overheating, power quality issues, and overloading. This means it’s critical to size your transformer appropriately for your solar system.

• Intermittent or predictable generation with a daily cycle;
• Current harmonics;
• Transient overvoltages;
• Frequent openings and reconnections, high probability of transients;
• Frequent single-phase shorts on MV;
• Electrostatic shielding, multiple secondary;
• Fast response from the park to the system;
• Demand from the system operator;
• Frequent switching;

Solar transformer design features

The WINLEY solar transformer is a product developed specifically for solar generation with a differentiated daily charging cycle. It has electrostatic shielding that does not absorb as much heat from the sun, reducing the production of gases inside the transformer, bringing more useful life and reliability to renewable energy generation plants.

1. Adopt electrostatic shielding design to eliminate electromagnetic
2. Comes with a NEMA 4X/3R control box equipped with contact meters for remote controlinterference of inverter
3. Double-split winding structure for thermal and electrical balance
4. Corrosion-resistant construction suitable for outdoor use
5. Advanced cooling and fire protection systems
