General Product Overview ：
Our photovoltaic (PV) transformers are high-efficiency, multi-winding step-up units specifically developed for utility-scale solar power plants. Featuring a unique dual-split or multi-winding design, these transformers allow for the direct connection of multiple solar inverters to a single unit, significantly reducing the cost and footprint of the solar array infrastructure. These units are engineered for high energy efficiency and extremely low no-load loss, ensuring maximum power capture even during low solar irradiance periods. Built for the harsh, sun-exposed environments of solar farms, our PV transformers deliver long-term reliability and stable grid connection.
