Solis S6-GC36K-US-APST 36kW Three Phase Grid-Tied Inverter

S6-GC36K-US-APST 36kW 3-Phase Inverter

The Solis S6-GC36K-US-APST is a 36 kW three-phase grid-tied string inverter for 480 V commercial rooftop and carport PV projects, delivered with an integrated APsmart (APST) module-level rapid shutdown transmitter for NEC 690.12-2020 compliance. Three independent MPPTs with a wide 180-1000 V operating window and string current up to 20 A accommodate high-power and bifacial modules across multiple roof orientations, while a greater than 1.5 DC/AC ratio maximizes energy harvest.

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, 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.

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 36 kW model hits the sweet spot for mid-size 480 V 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.
