Three-Phase String Inverter

The HYX-S30K/33K/36K/40K/50K-T is a three-phase string PV inverter suitable for commercial, industrial, and ground-mounted power plant applications. This series offers a power range of 30kW to 50kW, adapting to PV system configurations of varying sizes. Its maximum conversion efficiency reaches 98.7%, and it supports multiple MPPT inputs, effectively minimizing power loss caused by shading. It features a high current input capability of 12.5A, compatible with high-power modules. Built-in intelligent I-V curve diagnostics support remote operation and maintenance, as well as fault monitoring. With an IP66 protection rating, it operates reliably in outdoor environments. It supports multiple communication methods, including RS485, WiFi, and 4G, facilitating integration into power plant management systems. Its DC voltage reaches up to 1100V, and its three-phase AC output is suitable for 380V/400V power grids.
