Solis S6 80kW Three-Phase Commercial Solar Inverter (8 MPPT)
The Solis S6-GC80K is a high-performance three-phase grid-tied inverter engineered for commercial and light-industrial solar PV installations. Built on the Series 6 commercial platform, it combines excellent conversion efficiency, flexible MPPT architecture and advanced safety features to deliver reliable, long-term performance across complex rooftops and decentralised PV systems.
With high DC oversizing capability and intelligent monitoring as standard, the S6-GC80K is an ideal solution for businesses seeking maximum energy yield and operational confidence.
Commercial-Grade Power Performance
Designed for demanding commercial environments, the Solis S6-GC80K supports up to 120 kW of PV input power while delivering stable three-phase AC output. Its ultra-low start-up voltage enables earlier daily generation and improved energy harvest throughout the year, even in low-irradiance conditions common in the UK.
Flexible MPPT Design for Complex Arrays
The inverter features 8 independent MPPTs with a total of 16 string inputs, allowing highly flexible string layouts. With high current capability per string, it supports modern high-power PV modules and performs optimally on installations with multiple orientations, roof pitches or partial shading.
Integrated Safety & Electrical Protection
Comprehensive safety is built in as standard. The S6-GC80K includes AFCI (DC arc-fault circuit protection), an integrated DC switch, DC reverse-polarity protection and Type II surge protection on both DC and AC sides—helping to reduce fire risk and safeguard system components over the long term.
Smart Monitoring & Remote Management
The inverter integrates seamlessly with SolisCloud, providing real-time system monitoring, Smart String I-V Curve Diagnosis and remote firmware upgrades. These intelligent tools enable proactive fault detection, simplified maintenance and improved uptime across commercial solar portfolios.
Commercial Reliability & Warranty Support
Engineered for continuous commercial operation, the Solis S6-GC80K is supplied with a 5-year standard manufacturer warranty, with extension options available up to 20 years to support long-term asset protection and investor confidence.
