2 EVSE home solutions

[EVDRIVER]

Two separate outlets with two EVSEupgrades would be a very good solution. It would certainly be the least expensive.

I don't see you needing or wanting to take the 120v chargers with 99% of the time. You appear to have public chargers in case you need a charge when away from home, and 120v charging is too slow to be useful so it's not a great advantage to have a 120v charger in the trunk.

Yes, he can order the 16A version with an L6-20 and have two L6-20 outlets. This would minimize the circuit required and also allow for a portable 240V unit when needed.
