Deye Solar Batteries 2.56 kWh RW-L2.5A

Q: 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.

Q: 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.

Q: 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%.

Q: Does the RW-L2.5A scale up?

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

Q: 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.

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. We are an authorised Deye distributor and supply the RW-L2.5A from our own stock, with technical support before and after the sale.

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 the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
