Note: Knox recommend an 80% depth of discharge and quote cycle life at that same depth, so the usable figure and the cycle count are consistent with each other - which is not true of every brand here. Cycle life >6000 at 25°C, 0.5C/0.5C, 80% DoD to 70% of initial capacity, with a 10-year design calendar life. The main gain over the Powerwall 6.0 is scale: 15 units in parallel, with dedicated LINK-IN/LINK-OUT ports for battery-to-battery chaining. Series connection is not supported. Note the discharge window is narrower than the 6.0's - it stops at 48 V against the 6.0's 41.6 V, so it holds more voltage in reserve. RS485 and CAN for the inverter; RS232 is dropped. 442 x 470 x 160 and 46 kg, so slightly narrower and 1 kg heavier than the 6.0. IP20 indoor only. Around Rs 5,000 more than the 6.0 - worth it if you are building a bank, less so for a single unit.
