The Sungrow SG200HX-US is a transformerless, three-phase, grid-connected PV string inverter. It has 12 PV inputs rated at 40 A each, a full-power MPP voltage range of 850 V to 1300 V at 40 °C, and an AC voltage range of 528 V to 660 V. Its maximum efficiency is 98.9 % and its CEC efficiency is 98.5 %. Harmonic distortion is below 3 % at nominal power, and DC current injection is below 0.5 % of rated current. Built-in protections include DC reverse connection protection, AC short-circuit protection, leakage current protection, grid and ground fault monitoring, PV string current monitoring and Type II surge protection on both the DC and AC sides. It can supply reactive power at night and has an adjustable power factor. AFCI and anti-PID with PID recovery are optional extras. The inverter has a DC switch but no AC switch, so a separate AC disconnect has to be provided. It communicates over RS485 using Modbus and SunSpec, and it has LED indicators plus Bluetooth for setup through an app.
