Inverter Sungrow SG350-HX | Inverter Grid-Tie 350kW

The product currently being officially distributed by XBSolar is the String Inverter series, featuring up to 16 independent MPPT (Maximum Power Point Tracking) devices with a maximum efficiency of up to 99%. These inverters are compatible with various types of solar panels, including mono, poly, double-glass panels, and thin-film technology. Alongside an elegant design, they offer a range of superior features for users to have the most comfortable experience, including communication and monitoring options. This facilitates easy operation and maintenance through the web platform or application.

• Integrated software allows users to monitor smart electric currents on each string, scan, and diagnose online on the current-voltage curve (Online IV curve scan and diagnosis). Based on advanced systems and diagnostics, it accurately locates abnormal PV positions. Upgrades remote database for convenient operation and maintenance (O&M) tasks.
• Integrated with Recovery PID function. So, how does PID affect the system? PID is a complex process with many influencing factors. In general, PID will reduce the power output and lifespan of the solar panel. PID of the solar panel increases over time, affecting Voc and the Fill Factor (FF) of the panel. The degradation affects both individual panels with PID and the string containing the panels. The system’s power output may decrease by up to 90% over time. The Recovery PID function can repair degraded PV panels, increasing productivity by up to 10%.
• The Sungrow 350kW grid-tied inverter – SG350HX is designed to be compatible with both copper and aluminum AC cables, offering flexibility in design and optimizing installation costs. It can connect 2-in-1 DC cables instead of the traditional DC cable connection method, saving costs on DC power cables. All Sungrow solar inverters are designed with separate boards for easy replacement and repair over the operational lifespan.
• With a water protection rating of IP66 (NEMA 4X) for the inverter, IP68 for the cooling fan, and C5 corrosion protection, the SG350HX inverter exhibits excellent resilience to harsh environments. This makes it suitable for various installation scenarios and challenging conditions, including coastal areas in Vietnam.
• The integrated Arc Fault Circuit Interrupter (AFCI) function is capable of more accurately detecting and quickly eliminating main arc faults, ensuring safety for your solar power system. The Q at night function, Low Voltage Ride Through (LVRT) for overcoming low voltage incidents, High Voltage Ride Through (HVRT) for handling high voltage incidents, power operation and resistance control, and speed-up power control are all features designed to enhance the performance of your solar power system.
