One ca EASILY as a plug to the wall connector and just dial back to 40 amps for the codes.But the Gen 3 HPWC is white and matches the Powerwalls... and I still have my wife to contend with.

There used to be a HPWC available with a NEMA 14-50 plug attached.
If you want to pull the permit for a NEMA 14-50 outlet as an owner builder PM me, and I will do the CAD design work. Then you can hire whatever electrician you want and be fully permitted. The limitation will be charge rate, you will only get 66% of what the car is capable of. This is still fine for most people, and you would use the UMC.
Nothing is mis labeled, they do trip in pairs.
i respectfully disagree. look at the upr left top four. first one has air conditioning, tub and water closet and its 240 tripping buddy is just air conditioning. the first one should be only air conditioning ONLY. then middle two, which trip together, are all 120v loads.
Maybe it would make you feel better if I had labeled it "thermostat" instead of air conditioning (those top breakers are not 240). The actual AC is further down, on its own breakers.
the top breaker
top breakers are bonded together to trip in pairs. get the extra hardware removed...
I just need to vent at this point... PV+ESS = sucks. Real hard.
So I got a whole house backup from Sunrun. But I'm doubly-stupid because I did this before I actually bought an EV and got an EV charger installed.
Now that Sunrun has done their whole house backup, the electricians I've asked to install a Tesla charger won't do it. Because from their perspective the "whole house" is now under Sunrun's liability. Adding a Tesla charger would have to go into Sunrun's equipment and therefore wouldn't be allowed. These are two independently owned/operated electrician services in East Bay telling me this.
This panel is "full" because it's part of Sunrun's backup.

I own the solar and ESS (no lease or lein on the system)
I own this house (technically there's a mortgage but that's debt)
But somehow Sunrun's stupid 200A panel is sacred and can't be touched? HOW THE FUUUUUUUUUUUUU
PS. Sunrun can't install Tesla chargers because that's not in their wheelhouse. FFFFFFFF
PSS. If I knew Biden was going to be elected thus extending the ITC, I would have bought a Tesla before putting in PV+ESS.
Just to clarify, common trip is an internal connection and implies common disconnect when manually operated. The purpose of a handle tie is to take two independent breakers and make them common disconnect when manually operated. They still may trip independently.They are bonded together to trip in pairs.

Yes, the requirement for common manual disconnect on breakers serving a MWBC (where two circuits on opposite legs share a common neutral) is less than a decade old, I believe.

That's right, and that's the safety reasoning behind the requirement. Experienced electricians at the time the requirement was passed often had the reaction "if you don't know how to deal with an MWBC, you shouldn't be working on the wiring." And the downside is that the requirement has lead to a reduction in the use of MWBCs (you can't combine circuits into an MWBC when you need/want individual control of the circuits). So that has led to the use of somewhat more copper and somewhat more thermal heating due to voltage drop.Wow so someone could turn off a breaker thinking they de-activated the hot side, but then still get an unpleasant surprise since the neutral is being shared on another circuit?..
so don't install it into the subpanel
Then the EV charger is not visible to the Gateway 2. So stored Powerwall energy couldn't make its way to the charger.
I tried to oversize my PV system in anticipation of a future EV. Off-peak (overnight) rates on PG&E's EV2A plan to charge an EV are $0.17... which is 28% above the national average.
But that's where NEM will keep that balance.... Your solar output in day time can still compensate the charging at night after 12am.
The only downside doing that is you won't be charging your Tesla at night during a power outage.
