Deye GB-W 120.3kWh LiFePO4 Indoor Battery System, 512V 235Ah High Voltage
Ten 12.03kWh modules stacked in a column, 512V nominal and 120.3kWh on the nameplate, of which 108.2kWh usable at 90% depth of discharge. This is the size that fits a workshop, a hotel, a mid-sized retail unit: enough energy to shift a full day of consumption without going to container scale.
Nominal charge and discharge power in this configuration is 117.7kW, with 230A continuous and peaks up to 322A for one second: the system takes motor inrush without tripping into protection. Cooling is natural air, so there is no chiller to maintain, and communication runs over CAN and RS485 to hybrid inverters from 30 to 125kW.
The GB-W range is rated for at least 6,000 cycles at 25 °C with 0.5 C discharge and 70% end-of-life capacity: on daily cycling that is more than sixteen years. Installation is indoor, with built-in fire protection. Capacity can be configured from 60.1 to 192.5kWh by changing the number of modules, so the same architecture still works if your needs change. 10-year warranty.
