Well, so the other thing I'd say is that you're probably not looking to move hundreds of amps. If I could "borrow" 50 amps from one neighbor on each side of my house at 48V that's nearly 5kW but 2x 50 amp fuses are very, very doable and fairly cheap. I'm not saying this is a panacea BTW, just that it might be easier and cheaper for a few neighbors to band together in this kind of a way than for everyone to overbuild their battery banks. If you can go from needing to have 10kW peak of batteries and can instead get down to 5kW peak since you can borrow peak capacity that means your bank can be half as large.
