125kW Sodium-Ion Energy Storage System

Integrated Solar Power and Sodium-Ion Energy Storage

The 125kW / 261.6kWh Sodium-Ion Hybrid Energy Storage System is designed for commercial and industrial facilities seeking a flexible solution for solar power utilization, energy storage, and backup power. The system combines a 125kW hybrid inverter with two 130.8kWh sodium-ion battery cabinets, delivering a total rated battery energy of 261.6kWh.

Using NFPP sodium-ion battery technology, the system provides an alternative to conventional lithium-ion storage for applications requiring integrated renewable energy and energy management capabilities.

Key Product Highlights

1. High-Power Hybrid Inverter
The 125kW hybrid inverter integrates PV input, battery charging and discharging, grid connection, and backup output functions. It supports three-phase AC systems with 380V, 400V, or 415V rated voltage.
2. 261.6kWh Sodium-Ion Battery Storage
Two 130.8kWh battery cabinets provide a combined rated energy capacity of 261.6kWh. The battery system uses 170Ah NFPP sodium-ion cells and supports a high-voltage operating architecture.
3. Solar PV Integration
With a recommended maximum PV array size of 250kW and ten MPPTs, the system supports flexible PV string configuration for commercial and industrial solar installations, subject to detailed electrical design.
4. Grid and Backup Power Functions
The hybrid architecture supports grid-connected energy management and backup power operation. The inverter specifies a backup switching time of less than 10ms, subject to the operating conditions and final system configuration.
5. Integrated Energy Management Potential
The system can be configured for solar self-consumption, peak-demand management, and coordinated battery charging and discharging. Actual control functions depend on the selected EMS, metering, communication interfaces, and commissioning settings.

Typical Applications

• Commercial buildings and industrial facilities
• Factory solar-plus-storage projects
• Distributed photovoltaic energy systems
• Solar self-consumption optimization
• Peak shaving and electricity cost management
• Backup power for selected critical loads
• Industrial parks and commercial energy infrastructure
