DEYE Lifepo 5.1 Battery SE-G5.1 Pro-B

Features

Chemistry: LiFePO₄ (lithium iron phosphate) – offers good safety, stability and longer life.

Nominal energy: 5.12 kWh .

Usable energy: approximately 4.6 kWh (recommended depth of discharge 90%).

Nominal voltage: 51.2 V; operating voltage ≈ 43.2 – 57.6 V.

Capacity: 100 Ah.

Modular/expandable: up to 64 modules in parallel (total capacity up to ~327 kWh) suitable for larger systems.

Installation: Wall mounting, floor mounting or rack mounting (standard 19-inch cabinet depth ≥600 mm) possible.

Communication: including CAN2.0 and RS485 for connection to inverter/monitoring.

Warranty: 10 year warranty for this module.

Temperature range: charging: 0 °C to +55 °C (with optional heater even –20 °C), discharging: –20 °C to +55 °C.

Applications

Safe because LiFePO₄ chemistry is used without cobalt, which contributes to longer cycles and safe operation. Expandability makes it suitable for both standard residential installations and larger systems where more storage is required.

Modular and fairly compact design (≈ 440 × 133 × 540 mm, weight approx. 45 kg) makes installation relatively flexible.

Good communication capabilities support integration with home energy systems, PV installations and monitoring.

Balanced combination of capacity (~5 kWh) and usable energy (~4.6 kWh) suitable for self-consumption, peak shaving or emergency power scenarios.

Features

The module is designed for low voltage (LV) series, so please pay attention to compatibility with the inverter and system voltage.

Although usable energy is ~4.6 kWh, this is not sufficient for long-term backup of high consumption; for full autonomy, multiple modules are needed.

The IP value is IP20 (so indoor environment or technical room required, no outdoor use without additional protection).

The system requires proper installation and adequate ventilation; weight and dimensions must be taken into account at the installation site.

For optimal use, good communication/monitoring and correct settings of the inverter and battery are important (such as correct charge/discharge settings).
