Deye RW-M6.1-B

A slim 6.14 kWh, 51.2 V LiFePO4 battery with every kilowatt-hour usable at 100% depth of discharge, self-heating for cold-weather charging and a 10-year stated warranty.

Models Covered: DEYE-RW-M6.1-B

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: The Deye RW-M6.1-B hides serious storage in a slender profile: just 145 mm deep at 510 x 740 x 145 mm and 58 kg, it fits corridors and tight garage walls where bulkier packs will not. Nothing of its 6.14 kWh is held back - usable energy equals full capacity at the recommended 100% depth of discharge - and 3.07 kW of rated DC power flows at up to 100 A, with a 150 A peak for surges. Cold does not stop the charging: with heating on, the charge window stretches from the usual 0 to 55 degrees C down to -20 degrees C. The IP65 body seals against dust and water for wall or floor mounting, natural cooling keeps it silent, and 5 LEDs track charge with 3 more for status. Certified to UN38.3, CE, CEI 0-21, IEC62619 and VDE2510-50, it parallels to 32 units toward a stated 196 kWh, under a 10-year stated warranty with over 6,000 cycles.
