Key Features

High Safety and Reliability

Lithium iron phosphate cells with low internal resistance (≤50 mΩ) ensure thermal stability and safe operation in temperatures from -20℃ to 50℃.

Flexible Grid and Off-Grid Operation

Supports on-grid (400 V, 380±15% V) and off-grid (380 V, ±3% accuracy) modes with stable frequency (50 Hz, ±2%) for various system configurations.

Excellent Power Quality

Total harmonic distortion (THD) <5% and output power factor ≥0.99 provide smooth and stable AC output for sensitive loads.

Scalable Modular Design

51.2 V modules allow easy expansion, with container capacities of 2.5 MWh or 5 MWh, supporting flexible deployment and maintenance.

Advanced Thermal Management

Standard air cooling with optional liquid cooling ensures efficient heat dissipation and reliable performance under continuous operation.

Robust Protection and Certification

IP54-rated enclosure, Ethernet monitoring, automatic fire extinguishing system, and compliance with CE, UN38.3, UL, IEC62619, and VDE4110 standards.
