String Inverter SG350HX
The Sungrow SG350HX is a powerful 350 kW three-phase string inverter built for large commercial and utility-scale solar projects. It comes equipped with up to 16 MPPTs (Maximum Power Point Trackers) and delivers an impressive maximum efficiency of 99%, so it squeezes every possible watt out of your solar array—even when shading, clouds, or different orientations come into play. Designed to work seamlessly with today’s high-power PV modules (500Wp and above), it handles input voltages up to 1500 V and supports up to 20A per string. That means fewer strings, simpler wiring, and lower overall system costs. A standout feature is the Q at Night function, which provides reactive power support after sunset to help stabilize the grid and unlock extra savings without additional equipment.
For reliability you can count on, the SG350HX includes integrated DC switches, power line communication (PLC), smart IV curve diagnostics for quick troubleshooting, and full real-time monitoring capabilities. Its IP66 protection rating combined with intelligent forced-air cooling keeps it performing reliably in tough conditions, from -30°C to 60°C. It responds lightning-fast to grid demands (reactive power adjustment in under 30 ms) and meets global grid codes, making it a smart, future-proof choice for high-yield, cost-effective solar installations that actively support the grid. Perfect for developers and operators who want maximum energy production with minimal hassle and long-term value.
