Solis 60kW Three-Phase Grid-Tied String Inverter with Rapid Shutdown Transmitter – S6-GC60K-US-RSS

Commercial String Inverter with Integrated Rapid Shutdown Transmitter

The Solis S6-GC60K-US-RSS is a high-performance 60kW three-phase grid-tied string inverter engineered specifically for North American commercial solar applications. Designed around the latest Solis inverter platform, this model features an integrated Rapid Shutdown System (RSS) transmitter, simplifying NEC-compliant installations by eliminating the need for a separate rooftop transmitter.

With advanced MPPT technology, high conversion efficiency, intelligent monitoring, and commercial-grade reliability, the S6-GC60K-US-RSS helps maximize energy production while reducing installation complexity and long-term operating costs.

Ideal for commercial rooftops, carports, agricultural buildings, and ground-mounted arrays, the inverter delivers dependable performance in demanding environments.

Why Choose the Solis S6-GC60K-US-RSS?

  • 60kW commercial three-phase grid-tied inverter
  • Integrated Rapid Shutdown System (RSS) transmitter
  • Designed for North American commercial solar projects
  • 4 independent MPPTs optimize production across varying roof orientations
  • High-voltage PV input (up to 1000V) supports modern high-power modules
  • Advanced AFCI protection enhances system safety
  • Built-in monitoring and communications for remote system management
  • NEMA 4X / Type 4X enclosure for indoor or outdoor installations
  • Lightweight, transformerless design simplifies installation
  • Compatible with large rooftop and ground-mount PV systems
  • String current up to 20A – accommodates new high-power and bifacial modules

Built-In Rapid Shutdown Transmitter

Unlike traditional commercial string inverters that require a separate rooftop transmitter, the S6-GC60K-US-RSS includes an integrated Rapid Shutdown System (RSS/Tigo MLRSD) transmitter.

  • Fewer installation components
  • Reduced labor costs
  • Cleaner installations
  • Simplified NEC rapid shutdown compliance (NEC 690.12-2020)
  • Improved long-term reliability with fewer external devices

Optimized for Commercial Energy Production

The inverter utilizes 4 independent MPPT trackers to maximize energy harvest across multiple roof orientations, partial shading conditions, complex commercial roof layouts, and mixed string lengths. Independent MPPT operation helps maintain higher production throughout the day while increasing overall system flexibility.

Designed for Reliability

Commercial systems demand dependable operation year after year. The S6-GC60K-US-RSS incorporates numerous protection features, including:

  • Arc fault circuit interruption (AFCI)
  • DC reverse polarity protection
  • Ground fault monitoring / Grid monitoring
  • Anti-islanding protection
  • Overvoltage / Surge protection (DC Type II / AC Type II)
  • Short circuit protection
  • Temperature protection
  • Integrated rapid shutdown communications
  • String monitoring & I-V curve scanning

Its Type 4X / NEMA 4X enclosure with C5 Anti-Corrosion Level allows installation in harsh outdoor environments while protecting internal electronics from dust, rain, and corrosion.

Smart Monitoring & Fleet Management

Monitor your commercial PV system from virtually anywhere using SolisCloud monitoring platform. Features include real-time production monitoring, historical energy reporting, performance analytics, remote diagnostics, alarm notifications, and fleet management for multiple sites.

  • Supports RS485, Ethernet, WiFi, Cellular
  • Intelligent string monitoring, smart I-V curve scan
  • Scan to register on SolisCloud, supports remote upgrade and control
  • External power control interface supporting zero output power control
  • Modbus RTU (SunSpec compliant)

Ideal Applications
