Deye SE-F5 Pro LV 51,2V 5,12kWh Battery

Deye SE-F5 Pro LV 51.2 V 5.12 kWh Battery

The Deye SE-F5 Pro is a state-of-the-art, low-voltage (51.2 V) LiFePO₄ energy storage battery designed specifically for residential and small commercial energy storage systems. The 5.12 kWh nominal capacity, charging and discharging capability of up to 1C, and advanced BMS work together to ensure stable, long-term reliable operation.

General Features and Applications

The SE-F5 Pro is the ideal choice for new energy storage systems and for expanding existing low-voltage (LV) systems. Thanks to its modular design, it is flexibly scalable, making it easy to adapt to growing energy demands.

Key features:

• LiFePO₄ (LFP) battery chemistry – a safe, cobalt-free solution
• 5.12 kWh nominal energy storage capacity
• 51.2 V nominal voltage (operating range: 44.8–57.6 V)
• Optimized for residential and small C&I systems

Safety and intelligent BMS

One of the Deye SE-F5 Pro’s key strengths is its advanced battery management system (BMS), which ensures safe operation with active fuses and cell-level protection.

Advanced protection

• Overcurrent, overvoltage, and temperature protection
• active fuse for rapid fault handling
• LED status indicators (SOC, operation, error) and audible alerts

Performance and lifespan

The system supports up to 1C charging and discharging, which represents outstanding performance in this category.

Electrical parameters

• Rated capacity: 100 Ah
• Max. continuous charge and discharge current: 100 A
• Peak load: 150 A (for 120 seconds)
• Recommended depth of discharge (DoD): 90%

Long service life is guaranteed by stable LFP chemistry:

• ≥6,000 cycles (at 25 °C ambient temperature, 70% EOL)
• 10-year manufacturer’s warranty
• Approx. 16 MWh total energy delivery during the warranty period

Modularity and scalability

The true strength of the SE-F5 Pro lies in its scalability:

• up to 32 modules in parallel in the base configuration
• Up to 64 batteries can be connected using a CAN-Box
• parallel operation of multiple clusters is also possible

This allows the system to be scaled from smaller residential needs up to larger energy storage capacities.

Installation and environmental tolerance

The compact design and multiple mounting options simplify installation:

• wall-mounted
• floor-standing
• stackable design

Environmental specifications:

• charging temperature: 0 °C – +55 °C
• discharge temperature: –20 °C – +55 °C
• natural cooling
• IP21 protection
• Weight: approx. 44 kg
