About the Deye 6.14 kWh 51.2 V Lithium Solar Battery RW-M6.1-B

The Deye RW-M6.1-B is a 6.14 kWh, 51.2 V LiFePO4 home battery rated 120 Ah. It delivers 3.07 kW of DC power at up to 100 A continuous with a 150 A peak, and all 6.14 kWh are usable at a recommended 100% depth of discharge. What separates it from the rest of the RW line is depth: 145 mm. At 510 x 740 x 145 mm and 58 kg it mounts on a wall or stands on the floor in corridors too tight for deeper packs. One module is enough to start and up to 32 run in parallel for a stated 196 kWh. The recommended charge and discharge current is 60 A, cycle life exceeds 6,000 cycles, energy throughput is 20 MWh and end-of-life capacity is 70%, under a stated 10-year warranty. The IP65 enclosure and natural cooling keep it sealed and silent, 5 LEDs show state of charge from 20% to 100% and 3 more report working, alarm and protection states over CAN2.0 or RS485. With heating on, charging continues down to -20 degrees C. We are an authorised Deye distributor and supply the RW-M6.1-B from our own stock.

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.
