I really hope that you have 400A service.Yes, we have 3 separate meters on our house. Car charging, geothermal, house main. The EV and geothermal are metered at a different rate, but don't disable for time of use. The easy part is that I already have 6 gauge wire for the 50A car charging circuit going from the car charging panel/meter to the 14-50 in the garage. It should be able to be re-wired to a new battery back-up panel, which will contain all the essential house main circuits I want on the power back up. The battery back up wall charger will essentially be on the house main meter, but I probably won't charge from it, I'll just plug it in when there's a power outage.
Since we also have a 100A circuit between the EV meter panel and garage, we can just keep that for EV charging and install 2 new wall chargers, which communicate with each other, for daily charging on the EV TOU plan. The battery back up wall charger will essentially be on the house main meter, but I probably won't charge from it, I'll just plug it in when there's a power outage.
And it appears that you will get rid of the X or the Y?
