Three-Phase String Inverter

The HYX-S320K-HT is a three-phase string inverter with a rated output power of 320kW, suitable for industrial, commercial, and large-scale ground-mounted PV power plants. It supports multiple MPPT inputs, effectively reducing power generation losses caused by partial shading or string mismatch. It boasts a maximum efficiency of 98.8% and a wide DC input voltage range, making it compatible with high-power PV modules. It supports intelligent IV curve scanning and fault diagnosis, facilitating system maintenance and real-time monitoring. A built-in PID protection and repair module helps extend module life. Communication options include RS485 and Ethernet, allowing integration into power plant monitoring systems. With an IP66 protection rating, it is suitable for outdoor installation.
