Solis S6-GC(80–125)K Earns TÜV Rheinland VDE-AR-N 4110 Certification

Solis, a global leader in PV inverter technology, has announced that its S6-GC(80–125)K and S6-GC125K-HV three-phase grid-tied inverters have officially received the TÜV Rheinland Unit Certificate with VDE-AR-N 4110 compliance. This milestone confirms that Solis inverters meet Germany’s medium-voltage grid code requirements as well as FGW guidelines, setting a new benchmark for grid-friendly and reliable solar performance.

Built-In Safety with AI

The Solis S6-GC(80–125)K series combines advanced safety features with cutting-edge technology. Integrated AI-based millisecond arc protection (AFCI) ensures immediate response to arc faults, while real-time PV grounding detection enhances system reliability.

With optional arc fault and Rapid Shutdown (RSD) coordination, these inverters also improve fire safety at the system level — a critical requirement for both commercial & industrial (C&I) and utility-scale PV projects.

Intelligent Innovation for Smarter Control

Solis continues to push innovation with several industry-firsts:

• Master-slave export power control, supporting up to 10 units in parallel for flexible system scaling.

• Dual independent RS485 ports for seamless integration with third-party systems.

• Support for genset applications without requiring an external controller.

• Three-phase unbalanced output control, enabling dynamic power allocation per phase for compatibility with diverse power grids.

These features make the Solis S6-GC(80–125)K one of the most adaptable inverters in its class.

Perfect for High-Power PV Modules

The S6-GC(80–125)K inverter series is designed with high-power solar modules in mind. With an input current of up to 21A and support for a 150% DC/AC ratio, it ensures maximum energy harvesting. Intelligent I-V curve scanning, optimized AC/DC cable design, and remote O&M functions further reduce project costs and streamline operations.

Certified to IP66 protection, the inverter is engineered to withstand harsh natural environments, making it suitable for global deployment in large-scale C&I and utility projects.
