Deye SE-G5.1 Pro-B - 5.12 kWh LiFePO4 rack battery

Deye SE-G5.1 Pro-B is a 51.2 V, 100 Ah (5.12 kWh) LiFePO4 battery module designed for standard 19-inch rack mounting. It belongs to the Deye SE series, has an intelligent BMS and a built-in circuit breaker, and communicates with the inverter over CAN2.0 or RS485.

Main features:

  • Nominal voltage: 51.2 V
  • Capacity: 100 Ah, 5.12 kWh
  • Max. continuous current: 100 A, peak 150 A (2 min)
  • Cycle life: 6000 cycles at 90 % DoD
  • Parallel connection: up to 64 modules (327 kWh)
  • Communication: CAN2.0, RS485
  • Ingress protection: IP20

The module uses cobalt-free lithium iron phosphate cells and an intelligent BMS that provides complete protection. Cooling is natural. The operating voltage range is 43.2-57.6 V and the recommended depth of discharge is 90 %. The operating temperature is 0 ... 55 °C for charging and -20 ... 55 °C for discharging.

It can be mounted in a standard 19-inch rack (cabinet depth 600 mm), on a wall or on the floor. Modules connect in parallel, up to 32 without external setup and up to 64 in total (327 kWh). Typical configurations use Deye 12 kW and 15 kW inverters, with 3-12 batteries in parallel.
