Inverter Transformers are one of the most critical components in solar PV plants and are deployed in large numbers in large solar PV plants. Power output from PV Solar plant is inherently intermittent depending on available solar irradiance. Accordingly, load on solar inverter transformers also varies.
This study introduces a new topology for a single-phase photovoltaic (PV) grid connection. This suggested topology comprises two cascaded stages linked by a high-frequency transformer. In the first stage, a new buck–boost inverter with one energy storage is implemented.
Before untangling more puzzling windings decisions for isolation transformers, transformers with energy storage in microgrid scenarios, or PV systems supplying both three-phase and single-phase dedicated loads, let us consider a common case: a grid-tied PV system without storage. In this scenario, the PV system is exporting power to the grid.
Accordingly, load on solar inverter transformers also varies. Most of the time they operate at part load only. Hence, judicious selection of design parameters not only reduces the initial cost of transformer, they also help in optimizing the life cycle cost. Solar projects have very stringent project timelines.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
