☀️ Transformers for Solar (PV) Power Plants

Utility-scale solar depends on a chain of transformers: string/central inverter feed into collector transformers, which step up through a GSU to the grid point. Large PV plants need high-efficiency, high-reliability units sized for one-directional, inverter-based output.

Relevant transformer types: PT DT DRY
