Sungrow SG350HX-20 Three-Phase Inverter, 350 kW<\/strong><\/h2>\n
The Sungrow SG350HX-20<\/strong> is a three-phase grid-connected string inverter for utility-scale photovoltaic plants with a 1,500 V DC<\/strong> architecture. It features 6 independent MPPT trackers<\/strong>, with up to five inputs per MPPT and a maximum input current of 75 A per tracker, allowing the PV array configuration to be adapted to the project.<\/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. The datasheet specifies an output power of 352 kVA at 30 \u00b0C, 320 kVA at 40 \u00b0C and 295 kVA at 50 \u00b0C.<\/div>\n
