SigenTerra ES6400-4H

The SigenTerra ES6400-4H is a large-scale energy storage system designed for ground-mounted installation, with a nominal energy storage capacity of 6,400 kWh and a nominal AC power output of 4 × 400 kVA, for a total of 1,600 kVA. The system is based on lithium iron phosphate (LiFePO₄) battery cells, with a DC operating voltage range of 1,123.2–1,497.6 V.

The 4H model is designed for energy storage applications lasting approximately four hours. Intelligent liquid cooling helps maintain the batteries at the proper operating temperature, while the water- and gas-based fire suppression system ensures the safety of the system. With an IP55 rating and a design suitable for C3, C4, and C5 corrosion protection environments, the unit is suitable for outdoor industrial applications.

The system features Ethernet communication. Its low current harmonic distortion, wide reactive power control range, and compatibility with 50- and 60-Hz power grids support its use in power grid applications.
