My portable Level 2 chargers cost a hair under $300 each (3 yeas ago). They require installing a 60 amp circuit with a 50 amp dryer outlet (NEMA 14-50). I hired an electrician for that.
I have two circuits/outlets with 2 chargers always plugged into them (unless I take one with me on a trip) so that I can choose which one to charge with. One of them is constantly powered, the other is intermittently powered when solar is giving me free power. So if we come home with our EV charged for more than enough for the next day's driving, we'll plug it into the intermittently powered charger. Maybe we'll have free power to charge it more, maybe not. But if we come home with less range for the next day, we charge it with the constantly powered charger (may or may not be free, but will definitely be charged for the next day).
Sounds like you’ve got it covered.
