A solar transformer is a specialized electrical device used in photovoltaic systems to step up low inverter output voltage to match utility grid requirements. It safely manages variable solar loads, high ambient temperatures, and harmonic distortions produced during DC-to-AC power conversion.
Key Features & Design
Step-Up Duty: Boosts low voltage (such as 400V to 690V from inverters) up to medium or high grid distribution voltages (like 11kV to 33kV).Harmonic Tolerance: Built to withstand extra heat and stress from non-linear harmonic currents.
Specialized Windings: Often built with multi-winding configurations (such as three-winding or five-winding setups) to link multiple inverters directly.
Robust Insulation: Uses high-grade oil or dry-type insulation designed for outdoor and desert environments.
