Solis 125kW S6 Three-Phase Commercial Solar Inverter (10 MPPT)
The Solis S6-GC125K is a high-performance three-phase grid-tied inverter engineered for large-scale commercial and industrial PV installations. Delivering outstanding power density, advanced safety features and intelligent monitoring, it is ideal for complex rooftops and decentralised system designs requiring maximum flexibility and reliability.
Built on Solis’ Series 6 platform, the S6-GC125K combines high DC oversizing capability with multi-MPPT architecture to maximise energy yield while reducing balance-of-system costs.
High-Power Commercial Performance
Designed for demanding commercial environments, the Solis S6-GC125K supports up to 165 kW of PV input power and delivers stable three-phase AC output with excellent conversion efficiency. The wide MPPT voltage range and ultra-low start-up voltage ensure early morning generation and extended operating hours throughout the year.
Advanced MPPT Design for Complex Arrays
With 10 independent MPPTs and dual string inputs per tracker, this inverter enables highly flexible string layouts. It is ideally suited to installations with varying orientations, shading profiles or mixed module strings, maximising yield across complex commercial rooftops.
Integrated Safety & Protection
The S6-GC125K incorporates comprehensive protection as standard, including integrated AFCI (DC arc-fault circuit protection), DC switch, reverse-polarity protection and Type II surge protection on both DC and AC sides. These features reduce fire risk, improve system safety and ensure long-term operational reliability.
Smart Monitoring & Diagnostics
Intelligent monitoring tools such as Smart I-V Curve Diagnosis enable proactive fault detection and performance optimisation. The inverter supports PLC, GPRS and Wi-Fi communication and integrates seamlessly with SolisCloud for real-time monitoring, remote firmware updates and fleet management.
Commercial-Ready Reliability
Engineered for continuous operation in commercial environments, the Solis S6-GC125K is backed by a 5-year standard warranty, extendable up to 20 years for long-term asset protection and peace of mind.
