The Solis S6-GC50K-US and S6-GC60K-US are commercial three phase grid-tied solar inverters designed to convert DC electricity generated by photovoltaic modules into AC electricity for grid-connected solar power systems. With rated output powers of 50kW and 60kW, these models are suitable for commercial rooftops, industrial facilities, and distributed solar energy projects requiring a compatible 480V three-phase grid connection.
For solar installers, EPC contractors, project developers, and commercial PV system integrators, selecting the right grid-tied inverter is essential for achieving efficient energy conversion, flexible system design, and convenient long-term operation. The Solis S6-GC series combines high conversion efficiency, multiple MPPT inputs, integrated electrical protection, and intelligent monitoring in a transformerless inverter design.
With a maximum conversion efficiency of 98.8% and a CEC efficiency of 98.3%, the Solis 50kW and 60kW solar inverters help convert PV-generated electricity efficiently for commercial and industrial applications.
For businesses investing in solar power, inverter efficiency is an important consideration when evaluating system performance. Actual energy production depends on factors such as solar irradiance, module orientation, ambient temperature, system sizing, and installation quality.
These high-efficiency commercial solar inverters are designed to support grid-connected photovoltaic installations where dependable power conversion and appropriate system configuration are essential.
The S6-GC50K-US delivers a rated AC output power of 50kW, while the S6-GC60K-US provides 60kW of rated AC output power. Both models are designed for 480V three-phase grid applications at 60Hz.
The two power options allow project designers to select an inverter based on the required AC output capacity, PV array design, utility requirements, and overall project configuration.
Typical applications include:
Commercial rooftop solar power systems
Industrial and manufacturing facilities
Warehouse and logistics center solar installations
Distributed commercial photovoltaic projects
Business facilities seeking to utilize on-site solar generation
The final inverter selection should be based on the local grid requirements and a qualified electrical system design.
The Solis S6-GC series features a 3 or 4 MPPT configuration, depending on the model, supporting flexible photovoltaic array design. Its MPPT voltage range is 180V to 1000V, with a startup voltage of 180V and a maximum DC input voltage of 1000V.
Multiple maximum power point trackers can help accommodate PV arrays with different orientations or operating conditions when the system is properly designed. The inverter also supports high-power solar modules, helping system designers evaluate different module choices and string configurations.
Before installation, the PV array voltage, operating current, short-circuit current, string quantity, and temperature-related voltage variation must be checked against the specifications of the selected inverter model.
Electrical protection is a key consideration for commercial and industrial solar power systems. The Solis S6-GC50K-US and S6-GC60K-US series includes multiple protection functions to support safe grid-connected operation.
Key protection features include:
Integrated AFCI protection to help reduce fire risks associated with electrical arcing
DC Type II and AC Type II surge protection
DC reverse-polarity protection
Short-circuit and output overcurrent protection
Grid monitoring and anti-islanding protection
Integrated AC and DC disconnect switches
Temperature protection and string monitoring
These integrated functions help support system protection and maintenance. Appropriate installation, grounding, overcurrent protection, and compliance with local electrical codes remain essential.
The product flyer identifies a Type 4X enclosure and C5 anti-corrosion level. The datasheet specifies an operating ambient temperature range of -25°C to 60°C and a maximum operating altitude of 4000m.
These specifications help buyers and project designers assess the inverter's suitability for their installation environment. Actual suitability depends on site conditions, mounting arrangements, exposure, ventilation, and local installation requirements.
Type 4X is a US enclosure rating and should not automatically be converted to an IP65 rating without manufacturer confirmation.
The Solis S6-GC series supports intelligent string monitoring and I/V curve scanning, helping operators assess PV string performance and investigate potential system issues.
Communication options listed in the datasheet include RS485 and Modbus RTU with SunSpec compliance, with optional WiFi and cellular connectivity. The product flyer also mentions Ethernet support, which should be confirmed for the selected configuration.
SolisCloud monitoring supports convenient system visibility and remote management where the appropriate communication hardware and configuration are installed. These features can be useful for solar installers, commercial system operators, and maintenance teams managing distributed PV assets.
