Deye BOS-W

A shorter high-voltage rack of 5.12 kWh, 51.2 V modules: five to seventeen in series give 25.6 to 87.04 kWh, with 23.04 to 78.33 kWh usable at 90% discharge.

Models Covered: DEYE-BOS-W

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: Fit serious storage into a room where a full-height cabinet will not go. The Deye BOS-W stands 1,629 mm tall, noticeably shorter than its taller stablemates, yet strings five to seventeen 5.12 kWh, 51.2 V modules in series for 25.6 to 87.04 kWh of capacity, 23.04 to 78.33 kWh of it usable at the recommended 90% depth of discharge. The high-voltage bus runs 256 to 870.4 V nominal, operating between 220 and 992.8 V, and current flows at up to 100 A continuous with a 125 A discharge peak; 50 A is the recommended working figure. An air switch acts as the built-in breaker, CAN2.0 and RS485 ports speak both CAN and RS485 protocols to the inverter, and up to sixteen racks can be paralleled. The LiFePO4 cells exceed 6,000 cycles to 70% end-of-life capacity, the pack carries UN38.3 certification, and the stated warranty term is 10 years. Installation is indoors, in the IP20 rack, below 3,000 m.

Key Features & Technical Highlights

  • 87.04 kWh from a short rack: A string of five to seventeen 5.12 kWh modules yields 25.6 to 87.04 kWh inside a 1,629 mm frame.
  • 78.33 kWh at your service: At the recommended 90% depth of discharge, usable energy spans 23.04 to 78.33 kWh.
  • Flexible high-voltage bus: The bus covers 256 to 870.4 V nominal and operates from 220 to 992.8 V as modules are added.
  • Air switch protection: A built-in air switch handles disconnection, with 100 A continuous flow and a 125 A discharge peak.
  • Speaks CAN and RS485: CAN2.0 and RS485 ports run both CAN and RS485 protocols, and sixteen racks can parallel.
  • Proven LiFePO4 endurance: More than 6,000 cycles to 70% end-of-life capacity, certified to UN38.3.
