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.
Key Features & Technical Highlights
- 6.14 kWh usable: the full 120 Ah capacity is available at the recommended 100% depth of discharge, with 70% capacity still stated at end of life.
- 145 mm slim: 510 x 740 x 145 mm and 58 kg, wall-mounted or floor-mounted where deeper packs will not fit.
- 3.07 kW rated DC power at up to 100 A continuous charge or discharge, peaking at 150 A, with 60 A recommended for daily cycling.
- Charges down to -20 degrees C with heating on, against a standard 0-55 degrees C charge window and -20 to 55 degrees C discharge.
- Scales from 1 module to 32 in parallel for a stated maximum 196 kWh, controlled over CAN2.0 or RS485 at 43.2-57.6 V.
- IP65 sealed with natural cooling, BMS protection and cell balancing, certified to UN38.3, CE, CEI 0-21, IEC62619 and VDE2510-50.
Frequently Asked Questions
How much of the Deye RW-M6.1-B's 6.14 kWh is usable?
All of it. Usable energy is stated as the full 6.14 kWh of the 120 Ah, 51.2 V pack at a recommended 100% depth of discharge, and end-of-life capacity is stated at 70%.
How thin is the RW-M6.1-B and where can it be installed?
It measures 510 x 740 x 145 mm and weighs 58 kg, so it is only 145 mm deep. The IP65 enclosure is rated for wall-mounted or floor-mounted installation up to 2,000 m altitude in 5-95% humidity.
Can the RW-M6.1-B charge in cold weather?
Yes. The standard charge window is 0-55 degrees C, and with the heating function on it extends down to -20 degrees C. Discharge is rated from -20 to 55 degrees C either way.
How many RW-M6.1-B units can run together, and with which inverter?
From a minimum of 1 module up to 32 in parallel, for a stated maximum capacity of 196 kWh. At 51.2 V nominal and a 43.2-57.6 V operating range with CAN2.0 and RS485 ports, it suits a low-voltage hybrid inverter.
