SG33KTL-M/SG36KTL-M

String Inverter

Sungrow SG33KTL/36KTL is a three-phase PV inverter without transformer, which is a critical unit between PV Strings and utility grid in PV power system. Featuring multiple MPPT tracking, PID detects, and high-efficiency, the inverter is dedicated to converting direct power generated by PV modules into alternating current, which conforms to parameters of local grid, and feeds it into the utility grid.
