Deye AI-W5.1-B Modular LiFePO4 Battery 5.12 kWh 51.2 V IP65
The Deye AI-W5.1-B is the 5.12 kWh LiFePO4 battery module at 51.2 V of the Deye stackable low-voltage storage system. Modules stack onto the base and are closed on top by the PDU: 1 to 6 modules cover 5.12 to 30.72 kWh and, once the stack is complete, the assembly reaches IP65 protection.
It is the right solution for homes and small businesses that want tidy, silent storage that can be expanded without building work: cooling is natural and the floor area stays that of a single module. The integrated BMS handles protection and balancing and communicates over CAN 2.0 and RS485 with Deye 48 V low-voltage hybrid inverters. The cells are rated for more than 6000 cycles at 70% remaining capacity, 16 MWh of throughput and a 10-year warranty. To be combined with an AI-W5.1-PDU1-B unit and its base.
Key features
Stackable IP65 systemOne to six modules stack onto a dedicated base and PDU, and once the stack is complete the assembly reaches IP65 protection.
From 5.12 to 30.72 kWhEach module adds 5.12 kWh without changing the floor area: capacity grows vertically up to 30.72 kWh.
Natural coolingNo fans: the module works from -20 to +55 °C on discharge with natural cooling, therefore completely silently.
Over 6000 cycles and 10 yearsThe LiFePO4 cells are rated for more than 6000 cycles at 0.5C with 90% DoD and 70% remaining capacity, 16 MWh of throughput and a 10-year warranty.
