The Solis 25KW (S6-GC25K-NV) is an advanced three-phase on-grid string inverter designed specifically for commercial and industrial (C&I) solar installations. With a rated output of 25,000W and a maximum apparent power of 27.5kVA, it is perfectly suited for medium-sized rooftop projects. Its innovative 3 MPPT design with 6 string inputs allows for high design flexibility, effectively reducing string mismatch and maximizing energy harvesting even on rooftops with complex orientations or partial shading.
Built to handle the power demands of modern high-output modules, the Solis S6 series supports a string current of up to 16A/21A, ensuring compatibility with the latest 182mm and 210mm solar panels. Safety is a top priority, featuring integrated AFCI 2.0 protection to proactively mitigate DC arc-fault fire risks. The unit’s IP66-rated protection and intelligent redundant fan-cooling system ensure reliable, long-term performance in harsh environmental conditions. With 24-hour load consumption monitoring and smart I-V curve diagnosis via the SolisCloud platform, O&M is simplified, making this a future-proof investment for energy-conscious businesses.
