Solis S6-GC3P50K04-NV-ND is a three-phase grid-tied inverter with a rated power of 50 kW, designed for commercial and industrial photovoltaic installations. The device combines high efficiency, a wide MPPT voltage range and extensive DC-side configuration options, making it well suited for larger rooftop and ground-mounted PV systems.

The inverter is equipped with 4 independent MPPT trackers and 8 string inputs. The maximum input current is 42 A per MPPT, while the current of a single string can reach up to 21 A, facilitating compatibility with modern high-current PV modules. The wide MPPT voltage range of 180–1000 V provides great flexibility when designing PV systems.

The Solis S6-GC3P50K04-NV-ND supports a DC/AC ratio above 150%, allowing the PV array to be appropriately oversized. The inverter offers a maximum efficiency of 98.6% and a European efficiency of 98.1%, helping to reduce energy conversion losses.

The inverter offers advanced diagnostic and monitoring functions, including intelligent string monitoring, I/V curve scanning and Multi Peak Scan. Two independent RS485 ports enable communication with multiple devices, while Wi-Fi, 4G and DRM communication options are also available.

The IP66 enclosure allows the inverter to operate in demanding outdoor conditions. The device features an integrated DC switch and protection against DC reverse polarity, short circuits, AC output overcurrent, islanding and overheating. The inverter is also equipped with AFCI 2.0, providing protection against the effects of DC arc faults.
