About the Lemoen BOX39S 2.56kWh Energy Storage Battery
The Lemoen BOX39S 2.56kWh Energy Storage Battery is a wall‑mounted (or rack‑mounted) energy storage battery rated at nominal energy of 2.56 kWh, with a nominal voltage of 25.6 V and a capacity of 100 Ah. It employs LiFePO₄ cell chemistry, which offers enhanced safety, longer lifecycle, and superior thermal stability compared with many older lithium‑ion types.
The unit is designed for use with hybrid solar inverters or off‑grid systems (whether standalone or connected) and supports both wall‑mounted or rack‑mounted installations.
Detailed Features
- LiFePO₄ (Lithium Iron Phosphate) Cell Chemistry:
- Operates with LFP cells that provide better thermal and chemical stability, longer cycle life, and deeper discharge capability.
- Nominal Voltage & Capacity:
- At 25.6 V × 100 Ah yields a nominal energy storage of ~2.56 kWh, suitable for modest sized residential loads or as part of a multi‑module system.
- High Charge/Discharge Currents:
- The battery supports a maximum charge current of ~120A and maximum discharge current of around 100A.
- Cut‑off and Charge Voltage Specs:
- Standard charge voltage is ~29.2 V; discharge cut‑off voltage is about 20 V.
- Parallel & Series Expandability:
- The units support series and parallel connections allowing installers to scale capacity according to demand.
- Flexible Installation (Wall or Rack Mount):
- Design supports space‑efficient mounting; typical dimensions ~484 × 420 × 133 mm and weight ~27 kg for the 100Ah unit.
- Safety & Certification:
- The battery includes integrated BMS protections (over‑charge, over‑discharge, short circuit) and complies with standards.
- Temperature & Lifecycle Performance:
- Charge operating range: ~0‑65 °C; Discharge: ~‑20‑65 °C. Cycle life is typically around 4 000 cycles at 80% depth of discharge (depending on conditions).
