Sofar BTS 5K 5kWh high-voltage Battery Module

Sofar BTS 5K battery module is a compact component of an energy storage system based on LiFePO4 cells designed for high-voltage solutions. The module has nominal 5.12 kWh capacity with operating voltage about 400 Vdc and offers continuous power of 2.5 kW; modular design allows connection of up to four modules in a system providing total energy up to 20.48 kWh. The device features communication interfaces (CAN, LED) and is designed for user-friendly operation and low power consumption in sleep mode.

The enclosure is intended for floor mounting, cooling is via natural convection, and operating parameters include voltage range 350–435 Vdc and temperature range from -10°C to +50°C (charging from 0°C to +50°C). The module is designed for use with inverters ME/HYD 5K~20KTL-3PH and comes with battery distribution unit BTS 5K-BDU.
