Thanks a lot for the additional info.
I’m asking because I’m thinking about converting a car to EV. Having figured out how to do so at 48V, I’m now researching ways to integrate this battery on wheels into a grid-tied home (see this thread). I don’t have the car or the house yet, so it’s all purely hypothetical. But if it can be done, I will try to build it.
If it can’t be done, I will go your route. Unless bidirectional charging is finally implemented, which should have happened ages ago, of course.
