320kW String Photovoltaic Inverter
The 320kW String Photovoltaic Inverter is a three-phase solar inverter designed for outstanding energy conversion and management performance. The inverter aims to efficiently convert the direct current (DC) generated by solar panels into high-quality alternating current (AC) suitable for integration into the electrical grid. With a rated power of 320 kilowatts, this inverter is suitable for large-scale photovoltaic power plants, effectively integrating the energy output of solar farms into the power grid.
Product Description
This 320-kilowatt three-phase photovoltaic inverter employs advanced technology, offering high efficiency, stability, and reliability. One of its key features is its three-phase structure, which enables a more stable and balanced electrical output. A three-phase electrical system helps reduce power fluctuations during energy transmission, enhancing the overall efficiency of energy transfer.
