The JR Wall mounts on the wall of a garage, utility room or plant room and connects to a low-voltage inverter. Six models: three at 25.6 V, one at 48 V and two at 51.2 V, from 2.56 to 10.24 kWh.
Its lithium iron phosphate (LFP) cells are thermally stable and last at least 6,000 cycles, and 8,000 for the 8.03 kWh model. It talks to the inverter over CAN, RS485 or RS232; Bluetooth or Wi-Fi monitoring is available as an option.
