SUNGROW - SG50CX-P2 V21 inverter

The Sungrow SG50CX-P2 string inverter is a 50 kVA transformerless, three-phase inverter designed for DC photovoltaic systems up to 1100 V. It is suitable for high-power professional installations: commercial buildings, industry, agrivoltaics, carports, and solar power plants. Ground .

Its 4 independent MPPT trackers , with 2 strings per MPPT and a DC input current of 30 A per string, allow the connection of modules of more than 500 Wp and to manage multi-orientation configurations or partially shaded installations.

Dynamic shading optimization and integrated PID recovery help maintain production levels under varying installation conditions. Intelligent IV curve diagnostics and string current monitoring facilitate remote maintenance and diagnostics without requiring on-site physical intervention.

The plug-and-play design and light weight of 41 kg simplify handling and installation, even on rooftops or at height. Cooling is provided by intelligent forced ventilation, ensuring stable operation up to 60°C with derating above this temperature. The inverter is IP66 and C5 rated, with a maximum operating altitude of 4,000 m.

Maximum efficiency reaches 98.5% and European efficiency 98.3%, for a loss-free DC/AC conversion over the entire annual production cycle.
