Three-Phase String Inverter

The HYX-S15K/17K/20K/25K-T is a three-phase string-type photovoltaic inverter suitable for industrial, commercial, and large-scale residential photovoltaic power generation systems. This series offers four power models, covering a capacity range of 15kW to 25kW, allowing for flexible adaptation to arrays of different module capacities. Its multi-channel MPPT design effectively reduces the impact of shading or differences between strings on power generation, improving overall system efficiency. It supports a maximum DC input voltage of 1100V and is compatible with high-power and bifacial modules. It features sophisticated DC management and AC overload capabilities, enabling continuous full-power operation in high-temperature environments. Integrated RS485 and WiFi communications support remote monitoring and operation and maintenance management, complying with grid access regulations.
