The SE-G5.1 Pro-B Deye battery pack is a modern solution for energy storage systems based on lithium iron phosphate (LiFePO4) technology. It features high safety, a long service life, and stable operating characteristics.
With a capacity of 100 Ah and a nominal energy of 5.12 kWh, the battery is suitable for hybrid and off-grid solar installations, as well as for backup power systems. Usable energy is approximately 4.6 kWh at a 90% depth of discharge.
The device supports parallel connection of up to 64 modules, allowing the energy storage system to be scaled up to 327 kWh. This makes the SE-G5.1 Pro-B model an optimal solution for both residential and commercial sites.
The battery withstands more than 6000 cycles under normal operating conditions (25 °C, DoD 90%), which guarantees durability and cost-effectiveness.
Compact dimensions (440 × 133 × 540 mm) and a weight of about 45 kg simplify installation and integration into the system.
