Deye BOS-A

A high-voltage rack battery built from 7.68 kWh LiFePO4 modules, seven to twenty-one in series, delivering 53.76 to 161.28 kWh per rack for commercial systems.

Models Covered: DEYE-BOS-A

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: Keep a workshop, farm or small commercial site running on stored solar with a rack that grows one drawer at a time. The Deye BOS-A is assembled from 7.68 kWh, 38.4 V modules (BOS-A-Pack7.68, 200 Ah each) slotted seven to twenty-one high, giving a single rack 53.76 to 161.28 kWh, of which 48.38 to 145.15 kWh is usable at the recommended 90% depth of discharge. Its high-voltage bus spans 268.8 to 806.4 V nominal, and the PDU carries two DC interfaces sized for 50-100 kW hybrid inverters, with up to 10 inverters allowed in AC parallel and up to 16 racks side by side. LiFePO4 cells rated past 6,000 cycles retain 70% of capacity at end of life, while the BMS guards against over-charge, over-discharge, over-current and temperature faults with active cell balancing. Certification covers CE, IEC62619, IEC62040, UN38.3 and VDE-2510, and the warranty spans 10 years.

Frequently Asked Questions

What voltage class is the BOS-A?

It is a high-voltage system: 268.8 to 806.4 V nominal depending on module count, with an operating window of 235.2 to 919.8 V, so it belongs with high-voltage battery inverters.

Which inverter sizes suit the BOS-A?

The PDU (BOS-A-PDU-2) provides two DC interfaces intended for 50-100 kW hybrid inverters, and up to 10 inverters can run in AC parallel on larger sites.

How much energy can one BOS-A rack hold?

Between 53.76 and 161.28 kWh depending on whether 7 or 21 modules are fitted, with 48.38 to 145.15 kWh usable at 90% depth of discharge; 16 racks can be paralleled beyond that.

Where should a BOS-A be installed?

Indoors: the enclosure is rated IP20 and rack-mounted in 3U module format, measuring 610 x 1900 x 610 mm and weighing 525 to 1,501 kg depending on configuration.

What lifetime and warranty does the BOS-A carry?

Cycle life exceeds 6,000 cycles to 70% end-of-life capacity, and the stated warranty term is 10 years.
