Deye GB-L80 Ultra 80.64kWh 806.4V NEPT G High-Voltage LiFePO4 Battery

The Deye GB-L80 Ultra provides 80.64 kWh of nominal LiFePO4 storage from 14 stacked 5.76 kWh modules, operating at a nominal 806.4 V. It is positioned as the heated NEPT G option for cold-climate homes and demanding outdoor-energy applications, and this exact capacity is particularly well matched to the highest-capacity single-stack projects in this NEPT G model table, where maximum stored energy per tower is the priority. The system maintains a 75 A continuous charge/discharge rating, with 104 A short-duration charge and 135 A short-duration discharge capability, so the electrical performance is not diluted as the stack grows. A 90% recommended depth of discharge helps balance usable energy with long-term cycling, while CAN 2.0, RS485 and Bluetooth simplify inverter communication and commissioning. The IP66 enclosure and cable-efficient stack format support clean installations; at this capacity the complete tower measures 610×385×2137 mm and weighs 710 kg. The integrated heating capability is the decisive upgrade: charging can continue down to -20°C when heating is enabled, a major advantage in cold regions. For buyers comparing adjacent GB-L sizes, the key reason to choose GB-L80 Ultra is its exact 80.64 kWh capacity and 806.4 V operating point—not a generic family label.
