Deye BOS-G-Pack5.1 Rack Battery LiFePO4 5.12kWh 51.2V for HV Systems
The Deye BOS-G-Pack5.1 battery module is the building block of the BOS-G and BOS-G Pro high-voltage storage systems for small commercial and industrial applications: 5.12kWh of LiFePO4 cells, 100Ah at 51.2V nominal, in a 3U rack format weighing 46 kg.
Modules are connected in series, 5 to 16 units, inside a 3U-HRack-2G or 3U-LRack cabinet, managed by the BOS-G-PDU-2 control box: the result is clusters from 25.6 to 81.92kWh with voltages from 220 to 934.4V, and up to 16 clusters in parallel. They take 100A continuous and 120A peak discharge, are rated for more than 6,000 cycles at 90% DoD and come with a 10-year warranty. They pair with Deye three-phase high-voltage hybrid inverters.
