Solis S6-GC3P50K04-NV-ND 50kW 3-Phase Grid-Tied Inverter

The Solis S6-GC3P50K04-NV-ND is a three-phase string inverter with a rated output of 50 kW, designed for residential and commercial grid-tied solar installations. It features 4 MPPT trackers with 42A per MPPT, supporting up to 8 input strings and string currents up to 21A, enabling compatibility with high-power modern solar panels.

This inverter delivers maximum efficiency of 98.6% and a DC/AC ratio exceeding 170%, optimizing energy yield and system design flexibility. Intelligent string monitoring and smart I/V curve scanning enable rapid fault detection. Integrated AFCI protection (optional) and comprehensive safety features—including DC reverse-polarity protection, short-circuit protection, Type II surge protection (DC/AC), and anti-islanding—ensure reliable operation. The optional nighttime PID recovery function supports long-term system performance.

The transformerless design operates at -25 to +60°C with IP66 ingress protection and intelligent fan cooling. Communication is supported via RS485, with optional Wi-Fi, GPRS, and data logging capabilities. Grid connection complies with international standards including EN 50549-1, VDE-AR-N 4105, and IEC 62116.
