Dyness DL5.0C 5.12kWh Battery
A modular low-voltage LiFePO4 battery for solar energy storage. Each unit provides 5.12kWh nominal capacity, with up to 50 compatible units connected in parallel for 256kWh.
Key Features
- Scalable storage: 5.12kWh per unit, expandable to 256kWh with up to 50 units in parallel.
- Battery management: Integrated BMS with protection against overcharge, overdischarge, overcurrent and abnormal temperature.
- Indoor installation: IP20 protection, with wall-mounted, floor-standing or bracket-supported installation as specified in the manual.
- Cycle life: At least 6,000 cycles under the manufacturer’s stated test conditions.
- Inverter communication: CAN and RS485 for compatible low-voltage inverters; RS232 service interface.
Where to Use
Residential solar self-consumption, off-grid energy storage and backup systems using a compatible low-voltage inverter. Backup operation depends on the complete inverter and system design.
