400A/ 320A just seems like absolute overkills. Without an EVSE, our max draw is around 60A (this assumes Pool pump on high, all A/Cs (window)on max, all appliances on, dryer on, all lights on etc. (We use natural gas for heat / hot water / cooking so minimal electrical draw for those). Adding the 80A EVSE would push me to ~140A absolutely max (not sustained). Even had an electrician come out and verify that I wouldn't need a service upgrade (from 150A) to run the Lightning EVSE circuit. Why would I need to go to a 400A service, just to support back up power - that makes no sense!
Edit: still waiting for more information, but if this is true, I will just split the 100A circuit I ran to support two 50A EVSEs and forgo the backup power - but that would be a big loss for us. It was a major reason to go for the Lightning - but I can't see spending tens of thousands for an unneeded service upgrade.
