Deye BOS-G-PRO

The 5.12 kWh, 51.2 V LiFePO4 building block stretched for larger high-voltage stacks: five to seventeen in series yield 25.6 to 87.04 kWh, with a 120 A charge and discharge path.

Models Covered: DEYE-BOS-G-PRO

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: When a project outgrows a small rack, the module should not have to change. The Deye BOS-G Pro keeps the familiar 5.12 kWh, 51.2 V, 100 Ah building block, at 46 kg per module, and stretches the series string: five to seventeen modules assemble into systems of 25.6 to 87.04 kWh, spanning 256 to 870.4 V nominal with an operating window that reaches 992.8 V. Its recommended depth of discharge is 100%, meaning the capacity on the nameplate is the capacity you draw. The current path is rated at 120 A for both charge and discharge, peaking at 125 A, and sixteen racks may be paralleled for larger sites. Cells are LiFePO4 with a cycle life beyond 6,000 cycles to 70% end-of-life, CAN2.0 and RS485 handle communications, and the unit is certified to UN38.3, CE, CE-EMC, IEC62040, CEC and VDE. The rack installs indoors, is rated IP20 and is warranted for 10 years.

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 Saudi Arabia that is SEC, ECRA, SASO. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Key Features & Technical Highlights

  • Seventeen modules, 87.04 kWh: Five to seventeen 5.12 kWh modules in series give one cabinet 25.6 to 87.04 kWh.
  • A 120 A current path: Charge and discharge both run at 120 A continuous, peaking at 125 A.
  • Reaches 870.4 V nominal: System voltage spans 256 to 870.4 V nominal and operates up to 992.8 V.
  • Discharge to full depth: With a recommended 100% depth of discharge, nameplate capacity is what you actually use.
  • Broad certification set: Approved to UN38.3, CE, CE-EMC, IEC62040, CEC and VDE, with a 10-year warranty.

Frequently Asked Questions

How does the BOS-G Pro differ in scale from a smaller stack?

Its rack takes five to seventeen modules in series rather than a shorter string, so one cabinet ranges from 25.6 to 87.04 kWh across BOS-G25-Pro to BOS-G85-Pro configurations.

What currents can the BOS-G Pro sustain?

Charge and discharge are both rated 120 A continuous with a 125 A peak; the recommended everyday current is 50 A.

Is any BOS-G Pro capacity held in reserve?

No; the recommended depth of discharge is 100%, so a seventeen-module system makes its whole 87.04 kWh available.

What are the BOS-G Pro installation requirements?

An indoor position for the IP20 rack of 1060 x 2219 x 602 mm, floor loading for 290 to 883 kg, humidity of 5-85% and altitude below 3,000 m.

Which approvals and warranty back the BOS-G Pro?

It is certified to UN38.3, CE, CE-EMC, IEC62040, CEC and VDE, with a stated warranty of 10 years.
