Solis S6 125kW Three-Phase High-Voltage Hybrid Inverter

Solis S6 125kW Three-Phase High-Voltage Hybrid Inverter

The Solis S6-EH3P125K10-NV-YD-H Solarator is a high-capacity three-phase hybrid inverter developed for commercial, industrial and large energy-storage projects. It combines 125kW of rated AC output with advanced solar generation, high-voltage battery control, generator integration and fast backup functionality in one scalable platform. With up to 250kW of usable PV input, ten independent MPPTs and two battery ports, the inverter gives system designers the flexibility required for complex rooftops, ground-mounted arrays and high-capacity storage systems. Its scalable architecture supports future expansion while helping businesses improve energy resilience and manage grid consumption.

125kW Commercial Three-Phase Output

• 125kW rated grid output power
• 125kVA maximum apparent grid output power
• Three-phase 220/380V or 230/400V grid connection
• 50Hz or 60Hz rated grid frequency
• 189.9A rated output current at 380V
• 180.4A rated output current at 400V
• Power factor greater than 0.99, adjustable from 0.8 leading to 0.8 lagging
• Grid-current total harmonic distortion below 3%

Up to 250kW of Solar Input

• 250kW recommended maximum PV-array size
• 250kW maximum usable PV input power
• 1000V maximum PV input voltage
• 600V rated PV voltage
• 180V start-up voltage
• 150V to 950V MPPT operating range
• Ten independent MPPTs with up to twenty PV-string inputs
• 42A maximum input current per MPPT
• 60A maximum short-circuit current per MPPT
• MC4 quick-connect PV terminals

The ten-MPPT architecture provides strong design flexibility across arrays with different orientations or operating conditions. Final string voltage, current and module compatibility must be verified by the project engineer.

Dual High-Voltage Battery Connections

• Compatible with supported high-voltage lithium-ion battery systems
• 300V to 950V battery-voltage range
• Two independent battery ports
• 100A maximum charge or discharge current per battery port
• 200A maximum combined charge or discharge current
• CAN and RS485 battery communication

Two battery ports allow greater flexibility when configuring compatible commercial battery banks. Battery make, model, voltage, current capacity and communication compatibility must be confirmed before the system is designed or ordered.

Grid, Generator and AC-Coupled Integration

The inverter supports DC and AC coupling for flexible new installations, system extensions and retrofits. Its smart port can integrate supported grid-tied inverters, diesel generators and other compatible energy sources as part of a professionally engineered hybrid energy system.

• 125kW maximum generator-input power
• Three-phase 220/380V or 230/400V generator input
• 50Hz or 60Hz generator-input frequency
• 250A maximum grid-side AC input current

Fast Backup with High Surge Capability

• Less than 10ms backup switching time
• 125kW rated backup output power
• 120% rated power for 100 seconds
• 140% rated power for 10 seconds
• 160% rated power for 200 milliseconds
• Backup-voltage total harmonic distortion below 2% with a linear load
• Up to 100% allowable phase imbalance on grid and backup output
• Up to 41.66kW output per phase

Fast transfer and short-duration overload capability help the system support sensitive equipment and demanding start-up loads when the complete installation has been correctly engineered.

Scalable Parallel Operation

Up to ten compatible inverters can operate in parallel. Solis recommends using a Solis power-distribution cabinet for systems with more than six units. Parallel system design, protection, communications and commissioning must follow the manufacturer’s requirements.

High Conversion Efficiency

• 97.6% maximum efficiency
• 97.2% European efficiency
• 97.0% maximum battery-to-AC charge and discharge efficiency
• Transformerless topology

Monitoring and System Control

• Optional Wi-Fi, cellular and LAN communication options

Integrated Electrical Protection

• Anti-islanding protection
• Output overcurrent protection
• Short-circuit protection
• Integrated DC switch
• DC reverse-polarity protection
• DC Type II and AC Type II surge protection
• Optional AFCI 2.0 arc-fault protection

Warranty and Professional Installation

The inverter carries a five-year warranty that can be extended to ten years, subject to the applicable Solis warranty terms and project requirements. Installation, batteries, solar panels, switchgear, cabling, engineering and commissioning are not included in the product price. This commercial high-voltage inverter must be designed, installed and commissioned by qualified commercial solar professionals. Final suitability depends on the approved battery system, PV-array design, grid requirements, generator configuration, protection design and site-specific engineering.
