Deye 25.6–87.04 kWh 256–870.4 V Lithium Solar Battery BOS-W – High-Voltage Rack Battery System features

  • 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.

About the Deye 25.6–87.04 kWh 256–870.4 V Lithium Solar Battery BOS-W – High-Voltage Rack Battery System

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. We are an authorised Deye distributor and supply the BOS-W from our own stock, with technical support before and after the sale.
