The BOS-G is Deye's rack-mounted high-voltage LiFePO4 battery system, built from 5.12 kWh / 51.2 V BOS-GM5.1 modules connected in series (3 to 12 modules) behind an HVB750V/100A cluster control box. Configurations run from BOS-G15 (15.36 kWh, 153.6 V) to BOS-G60 (61.44 kWh, 614.4 V), with up to 16 racks in parallel for larger reserves.

With 100% usable depth of discharge, 100 A nominal current (125 A peak) and a cycle life above 6,000 cycles at 70% EOL, the BOS-G pairs with Deye SUN-...SG01HP3 high-voltage hybrid inverters for homes, villas and small commercial sites. It is certified to CE, IEC 62619, VDE 2510-50, UL1973, UL9540A and UN38.3, and is covered by a 10-year warranty.
