Single-Phase String Inverter

The HYX-S7K/8K/9K/10K/12K-S series of single-phase string inverters are suitable for residential and small commercial PV systems, supporting a rated output power range of 7kW to 12kW. This series features a multi-channel MPPT design, adaptable to complex installation environments and minimizing the impact of shadows on power generation. They offer a wide input voltage range and are compatible with a variety of module configurations. Integrated DC safety protection and intelligent arc fault protection ensure compliance with relevant safety standards. A built-in Wi-Fi or 4G communication module supports remote monitoring and operation and maintenance management. The aluminum alloy casing provides excellent heat dissipation and outdoor protection, making it suitable for a variety of installation environments.
