The Solis S6-GC80K is an 80kW three-phase on-grid solar inverter with eight MPPT trackers, 98.7% maximum efficiency, and an 8-year warranty, built for industrial rooftops, large commercial installations, and solar farm projects. Maximum apparent output is 88 kVA.
Eight MPPT trackers is the defining specification. Across an 80kW array spread over a large industrial site, panels face different directions, sit at different tilts, and fall under shade from plant structures, tanks, and adjacent buildings at different times of day. Eight independent trackers let each section generate at its own maximum instead of the whole plant being dragged down to its weakest string. At this scale, tracker granularity is the single biggest lever on delivered yield versus projected yield and across a 25-year asset life, that gap runs into lakhs.
98.7% efficiency at the top of the market. On an 80kW plant running for twenty-five years, the difference between 98.7% and a competitor's 98.2% is a measurable quantity of generation, every day, for the life of the asset. This is one of the highest conversion efficiencies available in commercial string inverters, and it is the first number an engineer evaluating this unit will check.
String configuration. The unit handles 8 × 50A short-circuit current across its trackers, with operating currents configured as 4 × (42 + 36) A, a wide 160-1000V MPPT range, and 1100V maximum PV input. That combination gives your design engineer real latitude in string layout across a complex site which matters when the array is large enough that a single uniform configuration is never possible.
The 8-year warranty on the single point of failure. In a plant this size the inverter fails before the panels, and its downtime stops an 80kW block of generation, not one string. Eight years of manufacturer cover is what protects the project economics through payback. At this scale, warranty length and service response are not features they are the bankability of the project.
Monitoring and installation. RS485 with optional Wi-Fi, GPRS, or PLC the PLC option being useful on large sites where running signal cable is impractical. At 93kg in a 1014 × 567 × 345mm cabinet, mounting and lifting need planning as part of the installation design.
Specification and supply at this scale. An 80kW inverter is one component in an engineered plant, not a purchase off a shelf. Array architecture, string sizing across eight MPPTs, cabling, protection, and metering are designed together. Send our team your project details roof or ground area, target capacity, load profile, and metering arrangement and we will coordinate specification and supply with our EPC partners.
