HV batteries + Rack systems

Deye high-voltage batteries and modular Rack systems for high-power hybrid installations.

Buying guide

Deye high-voltage battery systems for HV hybrid inverters and commercial installations. The systems are modular — they consist of battery modules, a BMS/PDU control unit and a rack. We offer three series: BOS-G, BOS-A and BOS-B, with a capacity from 40.8 kWh to 256 kWh per set.

Deye BOS-G — 40.8 to 81.6 kWh

5.1 kWh modules in a 3U-H rack. Ready-made sets: 8 modules (40.8 kWh, 409.6 V), 12 modules (61.2 kWh, 614.4 V) and 16 modules in two racks (81.6 kWh, 819.2 V). Charge and discharge current 100 A, operation from -20 to 55 °C, WiFi, RS-485, USB and CAN communication.

Deye BOS-A — 76 to 159.6 kWh

7.6 kWh modules. Sets: 10 modules (76.0 kWh, 384 V), 13 modules (98.8 kWh, 499.2 V) and 21 modules in two racks (159.6 kWh, 806.4 V). Charge and discharge current 160 A, operation from 0 to 55 °C, CAN 2.0 communication.

Deye BOS-B — 208 to 256 kWh

16 kWh modules for commercial and industrial applications, rack for up to 16 modules. Sets: 13 modules (208 kWh, 665.6 V), 15 modules (240 kWh, 768 V) and 16 modules (256 kWh, 819.2 V). Charge and discharge current 180 A, operation from -20 to 55 °C, 5+5-year warranty.

Common features

All series use LiFePO4 cells, a depth of discharge (DOD) of 90% and a service life of more than 6000 cycles. A complete set contains the modules, BMS/PDU and rack, so it is ready for installation. Modules and the BMS/PDU can also be ordered separately when expanding a system.

Frequently asked questions

Which battery series should I choose?

BOS-G suits smaller commercial systems (40–82 kWh), BOS-A medium-sized ones (76–160 kWh) and BOS-B large industrial installations (208–256 kWh). We will propose a configuration according to the inverter and the required capacity.

What does a complete set (Pack) contain?

Battery modules, a BMS/PDU control unit and a rack. The largest BOS-G and BOS-A sets have two racks and two BMS/PDU units.

Can the system be expanded later?

Yes, the systems are modular. We also sell modules and the BMS/PDU separately — we will check the technical expansion limits for your specific configuration.
