Deye 215 kWh 768 V Lithium Solar Battery BOS-B – High-Voltage Rack Battery System features

215 kWh in one cabinet

Fifteen 14.3 kWh, 280 Ah modules fill the 768 V enclosure, 193.05 kWh of it usable at 90% depth of discharge.

Fire suppression on board

Aerosol fire suppression and a circuit breaker come built into the cabinet.

Smart fan cooling

BMS-managed fans move air through the cabinet across its -20 to 55 degrees C discharge range.

98.5% round-trip efficiency

Up to 98.5% of stored energy comes back out, with 1.1x overload tolerance in reserve.

Scales to 4,300 kWh

Twenty cabinets operate in parallel, with up to 16 racks on a single PCS.

Ready for remote supervision

TCP, RS485 and CAN ports plus an LCD reporting state of charge and fault codes.

About the Deye 215 kWh 768 V Lithium Solar Battery BOS-B – High-Voltage Rack Battery System

Shave peak tariffs or ride through outages at commercial scale with a cabinet that treats safety as standard equipment. The Deye BOS-B loads 14.3 kWh, 280 Ah modules (BOS-B-Pack14.3) into a 768 V enclosure: a full stack of fifteen reaches 215 kWh, with 193.05 kWh usable at the recommended 90% depth of discharge, and configurations run from BOS-B70 through BOS-B215. Twenty cabinets can operate in parallel for as much as 4,300 kWh, with up to 16 racks on a single PCS and 1.1x overload tolerance. Aerosol fire suppression is built into the cabinet, smart fan cooling manages temperature, and an LCD reports state of charge and fault codes at a glance. Round-trip efficiency reaches 98.5%, LiFePO4 cells run past 6,000 cycles to 70% end-of-life, and TCP, RS485 and CAN ports connect the system to supervision. Certification includes CE, IEC62619, IEC62040 and UN38.3, under a 10-year warranty. We are an authorised Deye distributor and supply the BOS-B from our own stock, with technical support before and after the sale.
