Solis S5-GC75K 75kW 1000VDC Three Phase Inverter

The Solis S5-GC75K-US-APST S5-GC75K is a 75kW three-phase grid-tie inverter built for large commercial and utility-scale solar systems. Its transformerless topology reaches 98.7% peak efficiency (98.3% CEC) and pairs 8 MPPT trackers with a wide 180-1000V MPPT range for flexible string design. Rated at 480 VAC across three phases, it supports up to 16 input strings and 1000 VDC maximum PV input for high-density array layouts.

Key Features:

• 75kW output, up to 75 kVA apparent power
• 98.7% peak efficiency, 98.3% CEC
• 8 MPPT trackers, 16 max input strings
• MPPT range 180-1000V, start-up 195V
• Max PV input 1000 VDC, 32A per tracker
• 480 VAC three-phase, 60 Hz, 90.2A max output
• Transformerless with integrated AFCI and rapid shutdown
• DC/AC Type II surge protection, GFDI, anti-islanding
• Type 4X enclosure, -22°F to 140°F operation
• Cellular, Ethernet, RS485, WiFi, 10-year warranty

Ideal for commercial and utility-scale rooftop or ground-mount installations needing high-power three-phase output. String monitoring, I/V curve scanning and integrated PID recovery support long-term performance, while MC4 DC connectors and OT terminals (max 350 MCM) simplify integration into 480 VAC systems.
