Deye high-voltage lithium battery systems achieve a 25.6 kWh capacity by stacking five 5.12 kWh modular rack units in series. These configurations are built around premium Lithium Iron Phosphate (LiFePO4) chemistry and are engineered specifically to pair with three-phase high-voltage hybrid inverters (ranging from 5kW to 25kW) for residential and small-scale commercial setups.
