Dyness PowerDepot H5B 5.12kWh Battery
A low-voltage LiFePO4 battery for residential solar energy storage. Each unit provides 5.12kWh nominal capacity, with up to 10 compatible units in parallel for 51.2kWh according to the linked manufacturer documents.
Key Features
- Modular storage: 5.12kWh per unit, with up to 10 units in parallel for 51.2kWh nominal total.
- Battery management: Integrated BMS and circuit breaker, with protection against overcharge, overdischarge, overcurrent, overtemperature and short circuits.
- Flexible installation: IP65 protection with wall-mounted or floor-standing installation as specified in the manual.
- Inverter communication: CAN and RS485 for compatible low-voltage inverters.
- Cycle life: At least 6,000 cycles under the manufacturer’s stated test conditions.
Where to Use
Residential solar self-consumption, off-grid storage and backup systems with a compatible low-voltage inverter. The inverter and system design determine backup capability.
