Solis 30kW 208V Three Phase Three MPPT w/ AFCI w/ FAN w/APS
The Solis S6-GC30K-LV-US is a 30kW, 208V three-phase grid-tied string inverter designed for commercial rooftop solar installations. With three independent MPPTs, high-current PV inputs, integrated AFCI protection, and intelligent monitoring capabilities, it provides the flexibility and performance required for modern commercial photovoltaic systems.
Its wide operating voltage range helps the inverter begin producing energy earlier in the day and continue operating later, helping maximize overall system yield. Support for high-current solar modules also makes it suitable for many modern, high-power PV panel configurations.
Flexible Commercial Solar Design
Three independent MPPTs allow the inverter to manage multiple PV array sections with different orientations, shading conditions, or string configurations. This provides greater flexibility when designing commercial rooftop systems and helps improve energy production across the array.
The inverter supports a DC-to-AC ratio greater than 1.5, allowing system designers to install a larger PV array relative to the inverter’s rated AC output when permitted by the final system design and applicable electrical requirements.
Fast and Secure Installation
Integrated MC4-style DC connections and spring-clamp terminals help simplify installation while keeping cables properly secured. The optimized DC and AC connection layout can also help reduce installation time and system wiring costs.
The inverter can be installed on a wall or compatible metal racking system. Its Type 4X enclosure is suitable for indoor or outdoor installations when installed according to the manufacturer’s instructions.
Integrated Safety and Protection
Built-in Arc-Fault Circuit Interrupter protection helps detect and interrupt DC arc-fault conditions, reducing potential fire risk. The inverter also includes anti-islanding protection and integrated AC and DC protective circuitry.
This product line supports PVRSS and UL 3741-compliant system designs when used with approved compatible equipment and installed according to Solis documentation, local electrical codes, and utility requirements.
Advanced Monitoring and Communication
The S6-GC30K-LV-US supports intelligent string-level monitoring and remote I-V curve scanning, making it easier to identify system performance issues and monitor individual PV strings.
Communication options include:
• RS485
• Ethernet
• Wi-Fi
• Cellular communication
• SolisCloud remote monitoring
SolisCloud allows system owners and professionals to remotely view system performance, monitor energy production, receive operating information, and manage supported inverter functions. Communication accessories may be sold separately depending on the selected configuration.
Intelligent Cooling and Reliable Operation
The inverter uses intelligent fan cooling to manage internal operating temperatures during commercial applications. Its fuse-free design reduces potential failure points and helps support reliable long-term operation.
A nighttime PID recovery function helps reduce the effects of potential-induced degradation in compatible PV systems and may help maintain long-term module performance.

Important Application Information
This is a commercial grid-tied solar inverter. It requires an active 208V three-phase utility grid connection and does not provide battery storage, off-grid operation, or backup power during a utility outage.
Solar modules, rapid shutdown receivers, optimizers, monitoring accessories, external electrical protection equipment, wiring, and installation materials are not included unless specifically stated in the product listing.
The final PV array design must remain within the inverter’s published voltage, current, and operating limits. Installation, commissioning, and service must be completed by qualified electrical or solar professionals in accordance with the Solis installation manual, applicable electrical codes, utility requirements, and local authority having jurisdiction.
