Deye BOS-G 5.12kW HV Lithium Battery Datasheet


  • Battery Type: Lithium Iron Phosphate (LiFePO4) – This chemistry offers good safety, longevity, and efficiency.
  • Nominal Voltage: 51.2Vdc
  • Rated Capacity: 100Ah
  • Usable Capacity: Refer to the product datasheet or consult a Deye specialist for the confirmed Depth of Discharge (DoD) value. DoD reflects how much of the battery’s capacity you can realistically use (often between 80% – 90%). So, with a 90% DoD, the usable capacity would be around 4.6kWh (5.12kWh * 0.9).
  • Maximum Charge/Discharge Current: 125A
  • High Voltage System: Designed to work with Deye’s HV inverters, typically in the range of 120Vdc to 750Vdc.


  • Safe and Reliable: LiFePO4 chemistry is known for its stability and long lifespan, typically exceeding 6,000 charge cycles.
  • High Efficiency: Minimizes energy loss during charging and discharging cycles.
  • Rack-mountable Design: Enables efficient use of space for larger installations.
  • Intelligent Battery Management System (BMS): Provides features like over-charge, over-discharge, and temperature protection for extended battery life.


  • This battery is ideal for use with Deye SUN series hybrid inverters in commercial and industrial solar power systems for self-consumption and backup power applications.
