Deye Solar Batteries 5.12 kWh BOS-G

A 5.12 kWh, 51.2 V LiFePO4 module that stacks three to twelve high into a high-voltage rack of 15.36 to 61.44 kWh, all of it rated usable.

Models Covered: DEYE-BOS-G

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: Start with the energy you need today and add a 45 kg module whenever demand grows. The Deye BOS-G is built around a 5.12 kWh, 51.2 V module rated at 100 Ah; three to twelve of them connect in series inside the rack, producing systems from 15.36 to 61.44 kWh at 153.6 to 614.4 V nominal. Unusually, the recommended depth of discharge is 100%, so the usable figure matches the nameplate: nothing is held back. Charging supports a full 1C rate at up to 100 A, discharge peaks at 125 A, and sixteen racks can be paralleled when one is no longer enough. The LiFePO4 cells are rated for more than 6,000 cycles to 70% end-of-life capacity, communication runs over CAN2.0 and RS485, and the certification file lists UN38.3, CE, IEC62619, VDE2510-50, UL1973 and UL9540A. Deye states a 10-year warranty for the system, which installs indoors in an IP20 rack. We are an authorised Deye distributor and supply the BOS-G from our own stock, with technical support before and after the sale.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Key Features & Technical Highlights

  • 5.12 kWh per 45 kg module: Each 51.2 V, 100 Ah module weighs 45 kg and adds 5.12 kWh to the stack.
  • Nothing held in reserve: The recommended depth of discharge is 100%, so the 15.36 to 61.44 kWh nameplate is all usable.
  • 1C fast charging: Charges at up to 100 A (1C) and discharges at 100 A continuous with a 125 A peak.
  • Sixteen racks in parallel: CAN2.0 and RS485 communication lets up to sixteen racks act as one system.
  • UL-listed safety file: Certified to UL1973 and UL9540A alongside CE, IEC62619, VDE2510-50 and UN38.3.
  • 6,000 cycles and counting: LiFePO4 cells rated past 6,000 cycles to 70% capacity, warranted for 10 years.

Frequently Asked Questions

How is a BOS-G system sized?

By module count: each module adds 5.12 kWh, and a rack accepts three to twelve in series, giving 15.36 to 61.44 kWh; configurations are named BOS-G15 through BOS-G60.

How much of the BOS-G capacity can I actually use?

All of it: the recommended depth of discharge is 100%, so a twelve-module rack offers its full 61.44 kWh as usable energy.

What inverter voltage class does the BOS-G need?

A high-voltage one; the system spans 153.6 to 614.4 V nominal with an operating window of 124.8 to 700 V depending on module count.

How fast can the BOS-G charge and discharge?

It accepts a 1C charge at up to 100 A, discharges continuously at up to 100 A and peaks at 125 A, with 50 A the recommended day-to-day current.

Can BOS-G racks be combined, and where do they go?

Up to sixteen racks run in parallel, installed indoors: the rack is IP20-rated, measures 530 x 2219 x 602 mm and weighs 195 to 610 kg, at altitudes below 2,000 m.
