In hindsight if I were to spend more money I would buy a second SOK for 10KWh and 200A. During grid-down I also use the cart to power my 3000va UPSverter and back-feed my breaker panel.I would be concerned about changing BMS. It is there to protect the cells. Sure, you could put a 500A BMS in there, but then you would be drawing from the cells at 5C, which, as I understand it, is not good.
