DT-48200 M Electrical Ratings
Charging, Discharging and Voltage Limits
The battery's DC voltage and current limits determine suitable charging equipment and the available battery-side operating range.
Battery Voltage
The DT-48200 M operates within the specified 43.2–58.4V DC range. Charging and discharging equipment must respect these limits.
Charging
Charging uses a CC-CV method with the specified 56.8–58.4V voltage range and 150A charge current.
Discharging
The battery has a 200A discharge current specification. The inverter determines the available AC output to the load.
Temperature Limits
Charging is specified from 0°C to 55°C and discharging from -20°C to 55°C.
Inverter Integration
How to Match the DT-48200 M to a Solar Inverter
The inverter must support the DT-48200 M's battery voltage, charging settings, communication interface and protection requirements.
DC Voltage Compatibility
Check the inverter's supported low-voltage battery range.
Charge Control
Match inverter charging settings and battery management requirements.
BMS Communication
Use a supported CAN or RS485 protocol where battery-inverter communication is required.
Electrical Protection
Plan suitable DC isolation, overcurrent protection and system connections.
Communication Interfaces
CAN, RS485, RS232 and dry contact connections support communication and control functions according to the applicable interface protocol.
Inverter Operating Functions
Grid-connected, hybrid and backup functions depend on the inverter and overall system design.
Parallel Battery Planning
Parallel Battery Bank Configuration
The DT-48200 M supports up to 16 matching battery units in a compatible parallel system. The final battery count must comply with BMS, inverter and DC protection limits.
10.24kWh
Nominal energy for one DT-48200 M battery.
20.48kWh
Nominal energy for two matching batteries connected in parallel.
163.84kWh
Nominal energy for 16 matching batteries. The inverter, BMS and protection design must support this arrangement.
Battery Matching and Communication
Use compatible batteries with a supported BMS communication arrangement and appropriate operating conditions.
DC Connections and Protection
Cable sizing, connection layout, isolation and overcurrent protection must suit the combined battery bank.
System Architecture
Battery, BMS and Inverter Connections
The DT-48200 M provides DC energy storage. A compatible inverter manages power conversion for the connected AC system, while battery communication supports available monitoring and control functions.
- DC battery connection: transfers energy between the battery and compatible power conversion equipment.
- BMS communication: provides supported battery operating and protection information.
- Inverter: converts and manages electrical power according to its own rated capacity.
