Note: Knox rate the Rackwall range at a 90% depth of discharge and quote cycle life at that same 90%, down to 80% of initial capacity - a materially stronger claim than the Powerwall range, which is quoted at 80% DoD to 70% capacity. Same >6000 cycles, deeper discharge, stricter end-of-life threshold. The largest battery Knox list, at 280 Ah and 14,336 Wh. But note the current does not scale with the capacity: this model runs at 0.6C - 150 A charging and 170 A discharging - where the smaller Rackwall 10.5 manages a full 1C at 200 A both ways. More storage, slower to fill and empty. Standard 19-inch rack design with quick-lock press-to-release terminals, a 4.3-inch touch LCD that lets you switch inverter protocol on the screen, and RS485 plus CAN for the inverter with LINK-IN/LINK-OUT for battery-to-battery chaining. Charging window 55.2-57.6 V, end of discharge 48 V. Parallels to 15 sets; series is not supported. 10-year design calendar life. IP20, so indoor or cabinet only. 115.2 kg, so this is a two-person lift onto a rack. Knox call it the Rackwall 15 while Pakistani retailers list it as the "Rackwall 16 14.33kWh" - same battery, three different numbers. The datasheet figure is 14,336 Wh.
