Technical Summary

Sigenergy SigenStack BAT 12.0 battery module with LiFePO4 chemistry, 12.06 kWh total energy capacity, 314 Ah cell capacity, 105 kg weight, and dimensions of 770 x 300 x 363 mm. Rated for 0.5C nominal charge/discharge and up to 1C maximum charge/discharge. System data includes IP66 ingress protection, smart air cooling, aerosol fire suppression, smoke sensor and exhausting system, operating temperature range of -20 to 55 °C, and maximum operating altitude of 4,000 m with derating from 2,000 m. Up to 7 modules per stack and 21 modules per system are listed.

Installation Notes

Floor-standing installation. The datasheet notes that the battery controller should use the 'BST' model when the number of battery modules in a system is 19 or fewer, or in PV + ESS (DC coupling) projects.

Efficiency

The datasheet highlights higher energy density and less footprint. Smart air cooling is specified. Cycle life is stated as 10,000 under manufacturer test conditions.
