One thing to keep in mind guys is that even if you can, you may not want to install it at 22kW. There is a lot of talk and some view it as an inevitability that residential tariffs will move towards demand based charges rather than consumption. In other words you'll be paying more for the size of your pipe, rather than how much flows through it. 22kW is A LOT, which means your electricity bill will go up quite a bit. There are no concrete details yet but something to think about. I know the temptation of FULL POWER is very strong
If you can get away with 11kW, or 16A 3 Phase, which still gives you 50km of range per hour, that might be a better option.
