DOCAN ENERGY ZZ48300M Energy Storage Battery
The DOCAN ENERGY ZZ48300M is part of DOCAN’s ZZ-Series of vertical energy storage batteries. It combines a 51.2V battery architecture with integrated battery management, active balancing, touchscreen monitoring and wired and wireless communications in a floor-standing enclosure.
According to DOCAN’s 2026 product catalog, the Docan Energy ZZ48300M uses a 16-series, 1-parallel configuration with 16 × 3.2V 314Ah cells & 15,360Wh nominal energy.
This combination is intended for energy storage applications such as home solar storage, backup power and off-grid systems.
51.2V Battery Architecture
The Docan Energy ZZ48300M operates at a nominal voltage of 51.2V.
DOCAN specifies:
- 16-series, 1-parallel configuration
- 16 × 3.2V 314Ah cells
- 51.2V nominal voltage
- 314Ah nominal capacity in the 2026 catalog
- 15,360Wh nominal energy
- 58.4V charge cut-off voltage
- 40V discharge cut-off voltage
CC-CV (constant current-constant voltage) charging and constant-current discharge.
DAREN 200A Smart BMS
Battery management is handled by a DAREN 200A smart BMS.
The system supports a maximum specified charge current of 200A and a standard charge current of 100A. DOCAN lists the same 200A maximum and 100A standard values for discharge current.
The BMS platform is used throughout the ZZ-Series and is designed to support battery monitoring and system management.
Active Cell Balancing
The Docan Energy ZZ48300M incorporates active balancing with a maximum balancing current of 2A.
Active balancing helps manage differences between cells during battery operation and is particularly useful in large-capacity stationary energy storage systems where maintaining balanced cell behavior is important over the operating life of the battery.
Touchscreen and Wireless Monitoring
A 5-inch touchscreen is integrated into the battery for local monitoring and system interaction.
DOCAN also specifies:
- Wi-Fi connectivity
- Bluetooth connectivity
- App-based real-time monitoring
- RS485 communication
- CAN communication
These communication options allow the battery management system to exchange operating information with supported equipment and provide local or wireless access to battery status.
Specific inverter compatibility should be confirmed before installation rather than assumed solely from communication-interface availability.
Charging and Operating Conditions
DOCAN specifies a charging temperature range of:
32°F to 113°F (0°C to 45°C)
The specified discharge temperature range is:
-4°F to 140°F (-20°C to 60°C)
Storage temperature is specified as:
32°F to 104°F (0°C to 40°C)
Storage ambient humidity condition of less than 75%.
Floor-Standing Mobile Enclosure
The Docan Energy ZZ48300M uses the M-series floor-standing configuration within DOCAN’s ZZ product family.
The battery enclosure measures approximately:
27.17 × 11.81 × 34.25 in. (690 × 300 × 870 mm)
Net battery weight is approximately:
275.6 lb (125 kg)
Integrated caster wheels allow the enclosure to be repositioned for installation or service access. This should not be interpreted as meaning the battery is intended to be routinely transported while operating.
IP20 protection class, making proper indoor installation conditions important.
Cycle Life and Warranty
8,000 cycles at DOD ≥70%
10-year warranty
Energy Storage Applications
The ZZ48300M is suited to applications including:
- Residential solar energy storage
- Home backup power
- Off-grid solar systems
- Small commercial energy storage
- Small-facility backup systems
- Renewable energy storage installations
System design, inverter selection, protection equipment and installation requirements should be determined by the installer or system designer for the specific project.
