Deye RW-L2.5A

A compact 25.6 V LiFePO4 battery holding 2.56 kWh with 2.3 kWh usable, sealed to IP65 and light enough at 32 kg for one-room and small-system storage.

Models Covered: DEYE-RW-L2.5A

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: Not every system needs ten kilowatt-hours: the Deye RW-L2.5A serves the small end well - a cabin, a kiosk, a guard post, a modest apartment circuit - with 2.56 kWh of LiFePO4 storage at a 25.6 V nominal voltage, of which 2.3 kWh is usable at the recommended 90% depth of discharge. At 32 kg and a slim 350 x 680 x 160 mm, one person positions it on a wall bracket or the floor, and the IP65-sealed shell tolerates dusty, damp corners that would rule out an open-frame unit. An LCD reads out state of charge and working status, and CAN2.0 with RS485 handles inverter communication. It keeps working from -20 to 55 degrees C at up to 95% humidity and altitudes under 2,000 m. Where needs multiply, up to 32 units parallel toward a stated 81.92 kWh, and the cells are rated beyond 6,000 cycles with 4 MWh of energy throughput.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in France that is CRE France. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Key Features & Technical Highlights

  • 2.3 kWh usable energy: 100 Ah LiFePO4 cells at 25.6 V store 2.56 kWh, with 2.3 kWh usable at 90% depth of discharge.
  • One-person 32 kg install: At 32 kg and 350 x 680 x 160 mm, a single installer mounts it on wall or floor.
  • IP65-sealed compact shell: Dust-tight and water-jet-resistant for placement in rough corners and semi-exposed spots.
  • -20 to 55 °C operation: Works across -20 to 55 degrees C at up to 95% humidity, below 2,000 m altitude.
  • LCD status readout: An LCD reports state of charge and working status directly on the unit.
  • Stacks to 81.92 kWh: Up to 32 units parallel toward a stated maximum capacity of 81.92 kWh.

Frequently Asked Questions

What voltage system does the RW-L2.5A fit?

It is a 25.6 V nominal battery operating between 22.4 and 28.8 V, so it belongs with equipment designed for a 25.6 V battery bank - not with 48 V-class or high-voltage systems.

How small a load justifies the RW-L2.5A?

With 2.3 kWh usable from its 2.56 kWh capacity, it suits cabins, kiosks and single-room circuits where a larger unit would sit mostly idle.

Can the RW-L2.5A handle harsh spots?

Its IP65 shell seals out dust and water jets, and it operates from -20 to 55 degrees C at humidity up to 95%.

Does the RW-L2.5A scale up?

Yes - up to 32 units connect in parallel, with a stated maximum capacity of 81.92 kWh.

How does the RW-L2.5A connect and report?

CAN2.0 and RS485 ports carry inverter communication, while the built-in LCD shows state of charge and working status.
