Sungrow SG350HX Three-Phase Inverter, 350 kW<\/strong><\/h2>\n
The Sungrow SG350HX<\/strong> is a three-phase grid-connected string inverter for utility-scale photovoltaic plants with a 1,500 V DC<\/strong> architecture. The configuration specified in the datasheet features 12 independent MPPT trackers<\/strong>, with 14 or 16 MPPT options, and two string inputs per tracker.<\/div>\n
It achieves a maximum efficiency of 99.02 %<\/strong> and provides a three-phase output at 800 V AC<\/strong>. It integrates RS485 and PLC communication, intelligent I-V curve diagnostics and AC and DC insulation monitoring. Its declared output power is 352 kVA at 30 \u00b0C, 320 kVA at 40 \u00b0C and 295 kVA at 50 \u00b0C.<\/div>\n
