DOCAN ENERGY 32kWh LiFePO4 Energy Storage Battery
The DOCAN ENERGY 32kWh-51.2V-PD provides high-capacity energy storage in a mobile floor-standing enclosure for solar energy storage, backup power and off-grid applications.
DOCAN ENERGY 32kWh-51.2V-PD battery architecture uses 32 × 3.2V 314Ah LiFePO4 cells configured as 16 series × 2 parallel, producing a nominal system voltage of 51.2V, nominal capacity of 628Ah, and nominal energy of 32,153Wh.
51.2V, 628Ah LiFePO4 Storage
With more than 32kWh of nominal energy, the DOCAN ENERGY 32kWh-51.2V-PD is designed for applications where a conventional small residential battery does not provide enough storage capacity.
The LiFePO4 chemistry combines high energy-storage capacity with the thermal stability and long-cycle characteristics required for stationary energy storage.
High-Current Charge and Discharge Capability
The battery supports:
- 100A standard discharge current
- 200A maximum discharge current
- 100A standard charging current
- 200A maximum charging current
Charging uses a CC-CV constant-current/constant-voltage method, with a 58.4V charge cut-off voltage. The discharge cut-off voltage is 40V.
Smart BMS with Active Balancing
A KESHENG 200A smart BMS manages the battery system, while 2A maximum active balancing helps maintain consistency between cells.
The battery also incorporates Wi-Fi and Bluetooth app monitoring, allowing battery information to be monitored remotely from a compatible device.
5-Inch Touchscreen
A built-in 5-inch touchscreen provides an accessible local interface for viewing and managing battery information.
The large display is integrated directly into the battery enclosure, keeping essential operating information available at the system itself without requiring a separate external display.
RS485 and CAN Communication
RS485 and CAN communication interfaces are provided for integration with compatible inverter and energy-storage equipment.
The DOCAN ENERGY 32kWh-51.2V-PD supports communication with a broad range of inverter platforms, including brands such as Deye, Growatt, GoodWe, Victron, SMA, Sofar, Solis and others.
Mobile Floor-Standing Design
Despite its large capacity, the battery uses a wheeled enclosure that allows it to be repositioned more easily during indoor installation and servicing.
The enclosure measures 800 × 430 × 640 mm (31.50 × 16.93 × 25.20 in.) and the battery has a net weight of 238 kg (approximately 524.7 lb.). Its protection class is IP20, making it an indoor energy-storage product.
Long-Term Energy Storage
Cycle life is rated at not less than 8,000 cycles with ≥70% capacity retention under the specified test conditions. The complete battery carries a 10-year warranty.
