Solis S6-GC60K-US 60kW Three Phase Grid-Tied Inverter

S6-GC60K-US 60kW 3-Phase Grid-Tied Inverter

The Solis S6-GC60K-US is a 60 kW three-phase grid-tied string inverter for large 480 V commercial rooftop and carport PV projects. Four independent MPPTs with a wide 180-1000 V operating window, 8 string inputs, and string current up to 20 A give designers real layout flexibility for multi-orientation roofs and high-power bifacial modules, while a greater than 1.5 DC/AC ratio maximizes harvest from oversized arrays.

The S6 platform reaches 98.8% max efficiency (98.3% CEC) and packs commercial-grade protection into a Type 4X, C5 anti-corrosion enclosure: integrated AFCI, module-level rapid shutdown transmitter options (APST / RSS / NEPT), DC and AC disconnects, DC Type II / AC Type II surge protection, intelligent string monitoring with smart I-V curve scan, and optional nighttime PID recovery. An external power control interface supports zero-export control for utility interconnection requirements.

Solis S6-GC60K-US Features

• 60 kW Three-Phase Output: 60 kW / 60 kVA at 480 V with 72.2 A max output current, one of the most powerful units in the S6-GC series.

• Rapid Shutdown Options: Order with an integrated APS (APST), Tigo (RSS), or NEP (NEPT) module-level rapid shutdown transmitter for NEC 690.12-2020 compliance.
• AFCI + Integrated Disconnects: Integrated arc-fault protection, DC and AC disconnects, and DC/AC Type II surge protection reduce fire risk and BOS cost.
• Smart String Monitoring: Intelligent string monitoring, smart I-V curve scan, and multi-peak scan via SolisCloud with remote upgrade and control.
• Type 4X + C5 Rated: Type 4X enclosure with C5 anti-corrosion level and intelligent fan cooling, operating from -13°F to 140°F.

The Preferred String Inverter for Commercial Rooftops

Solis positions the S6-GC(25-60)K-US series as the preferred PV string inverter for large commercial rooftop projects, and the 60 kW model is its workhorse for 480 V C&I installations. A separable AC wiring box speeds installation and service, communication options span RS485, Ethernet, Wi-Fi, and Cellular (Modbus RTU, SunSpec compliant), and every unit carries a 10-year standard Solis warranty with extended options available through Solar Electric Supply.
