Product information "SG350HX-20, 350kW"
This inverter requires a mains voltage of 800 V.
AC connection can be made with two wires per phase. The appropriate cable entry is available separately.
The SG350HX-20 is the largest version of a string inverter from Sungrow. Its practical features, high input currents, and extensive functions leave little to be desired. Intelligent IV curve diagnostics, integrated Type 2 AC+DC surge protection, and 24-hour insulation monitoring – all optimized for functionality and safety. Due to the long cable lengths, this model also supports two AC wires per phase.
