Highlights
- Modular HV stack — combine 3–12 × 5.12 kWh modules (BOS-GM5.1) for 15.36–61.44 kWh per cluster.
- 19-inch embedded module design for fast rack installation and maintenance.
- Cobalt-free LiFePO4 with intelligent BMS (over-charge/discharge, over-current, temperature protection and cell balancing).
- ≥6000 cycles at 90% DoD, 10-year warranty.
- Up to 6 months shelf storage without recharge; remote firmware upgrade via compatible Deye inverters.
System components
A complete BOS-G cluster requires:
- BOS-GM5.1 battery modules (5.12 kWh each, 44 kg)
- HVB750V/100A high-voltage cluster control box (120–750 Vdc, 100 A nominal / 125 A max)
- 3U-HRACK (12 modules) or 3U-LRACK (8 modules) 19″ rack
Multiple clusters can be paralleled for larger commercial systems.
