Deye BOS-G 5.12 kWh High-Voltage LiFePO4 Battery Module

The BOS-G module is the building block of Deye's high-voltage battery system. Each module stores 5.12 kWh (51.2 V, 100 Ah) in lithium iron phosphate cells, which we favour for long cycle life and stable behaviour in warm plant rooms.

A module does not work on its own. Between 3 and 12 modules stack in series in a rack under one HVB750V/100A control box, giving a system from 15.36 kWh to 61.44 kWh, and the system connects to a compatible high-voltage hybrid inverter. That makes it a fit for larger homes, hotels, and commercial sites that need hours of backup rather than minutes.

Deye rates each module for at least 6,000 cycles (at 25 °C and 0.5C, to 70% of original capacity) with a recommended 90% depth of discharge. It communicates over CAN or RS485, discharges from -20 to 55 °C, and is IP20, so it belongs indoors in a ventilated space.

We size the module count to your load and backup hours, and commission the control box and inverter together.
