My understanding is that if the car is charging and is going to exceed the load on the panel the charge controller will stop power going to the car. He suggested this as a cheaper alternative to upgrading the panel.
That kinda makes sense, but it seems to be a very elaborate/expensive solution that doesn't really solve the problem. If I were limited by the number of remaining amps, I would just settle for a lower amp limit going into the HPWC. The fact that controller will shut off power completely for the charger means you gotta spend energy making sure your car is still charging because potentially something in your house has cause it to shut off. I'm more of a "set it and forget it" type of person.
