Another option may be a main breaker, bypass breaker interlock kit in the non-backed up panel. The home would obviously be limited to 200A total during an outage but, if he doesn’t mind going and swapping Cybertruck chargers he may also not mind going down to the basement and hitting the interl

Yes, but the PV system would need to be split, and inevitably, the balance of PV and battery assigned to each distribution panel will not match up well at times. A single battery and a single PV system serving the entire property is what he really wants. Tesla is not the answer for that today. I su

In my view, the real consideration here is whether or not the utility should be allowed to be the arbiter of how much capacity a homeowner is allowed to back up. My stance is no. They can't tell you how big of a backup generator you can have. Why should they get to dictate what capacity the custome

Still Jason it seems very crazy! When I do energy for a home in your neck, usually offgrid, we use mini-splits and in a large home like you are referring with the grid, the same thing, use a split for a zone, like the kitchen and save all that wasted battery capacity backing up the whole home. T
