DEYE SE-G5.1-Pro-B 51.2V energy storage Battery 100Ah 5.12kWh
Modern energy storage for home and business
DEYE SE-G5.1-Pro-B energy storage is an advanced lithium iron phosphate (LiFePO₄) battery designed for reliable, safe energy storage. Thanks to its high capacity 5.12 kWh and a nominal voltage of 51.2V, is ideal for solar systems, off-grid installations and emergency backup power.
Key features:
Energy capacity: 5.12 kWh
Nominal voltage: 51.2V
Rated capacity: 100Ah
LiFePO₄ technology – high durability and safe operation
More than 6000 charge cycles at 80% DOD (depth of discharge)
Expandable system – support for parallel operation in larger energy storage systems
Built-in BMS – intelligent protection against overcharging, deep discharge and overheating
Compact, modular design making installation and integration with other devices easier
Flexible installation and scaling
SE-G5.1 Pro-B is a battery based on 19”, offering three convenient installation methods:
- Rack (19-inch cabinet) – ideal for organised, extensive systems.
- Wall – saves space and provides a neat installation in the plant room.
- Floor (free-standing) – stackable modules for easy expansion
Thanks to modular design the system can scale from one 5.12kWh module to as many as 16 modules. This makes the battery suitable for home PV systems, as well as in small businesses or higher-demand energy-storage systems.
