Deye GB-L17 Plus 17.28kWh 172.8V NEPT G High-Voltage LiFePO4 Battery

The Deye GB-L17 Plus provides 17.28 kWh of nominal LiFePO4 storage from 3 stacked 5.76 kWh modules, operating at a nominal 172.8 V. It is positioned as the long-warranty NEPT G choice for premium residential and professional high-voltage storage, and this exact capacity is particularly well matched to compact premium homes that want high-voltage storage without starting with an oversized battery bank. 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 610×385×597 mm and weighs 171 kg. A 10-year warranty and the broader Plus certification set make it especially suitable for professionally specified home-energy projects. For buyers comparing adjacent GB-L sizes, the key reason to choose GB-L17 Plus is its exact 17.28 kWh capacity and 172.8 V operating point—not a generic family label.
