Technical Summary

Sigenergy SigenStack BC M2-0.5C battery controller for C&I energy storage systems. Operating voltage range 550 to 1100 V. Maximum input current from inverter 180 A and maximum output current to inverter 180 A. Communication via CAN. Floor-standing installation. System ingress protection IP66. Cooling: smart air cooling. Noise level below 70 dB. Operating temperature range -20 to 55 °C. Maximum operating altitude 4,000 m, with derating at 2,000 m.

Installation Notes

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

Efficiency

The source document states higher energy density and less footprint at system level. Nominal charge/discharge rate is 0.5C, with a maximum charge/discharge rate of 1C in the associated battery module data.
