I have a 50 amp circuit on which I installed two Tesla Wall Chargers in a daisy chain. If I hook up both Tesla's to charge at night, with one starting at 11 PM, and the other at 3 AM, I expected the first one to charge at full power (40 amps) during 11 PM to 3 AM, and then charge at 20 amps each after 3 AM. However, I am finding that merely connecting both chargers to the cars, even when the second one is not actively charging cuts the power to 20 amps on the first vehicle.
Did we set these up wall chargers incorrectly? Or is this the way it works, and I should set both vehicles to start charging at 11 PM - and let them charge at 20 amps each through the night.
