GM Energy Vehicle to Home

Installed this at the end of August. One of the first 5 installed in the US.

Very pleased with it. It's much, much, much more reliable than the Ford setup.

During the one-hour-long inspection, the inspector, who had never encountered a V2H setup before, was intrigued by the operation.

That's purty!

How much of a load can it handle?

 

[retirede]

Very clean installation. Interconnecting wiring in the wall?

 

[Chamuit]

Thanks. @ptonsparky

@retirede Yes. Conduits run through to the outside wall and back in. Looks like a cluster. But that's the desired inside look.

The charger is 19.2 kW (80A).

The Home Hub (MID) is rated for 200A. This setup is on a 40A detached garage circuit. The max V2H output. It will run a 2-ton AC. The Ford V2H would not.

Specs are at the bottom.

This setup is on a 40A detached garage circuit.

The specs say the inverter output is 9.6 kW, so you had to dial that back to 7.7 kW because you only had a 40A feeder available?

@wwhitney I did not. Consumption won't exceed the output rating.

@wwhitney I did not. Consumption won't exceed the output rating.

Pretty sure you are required to do that, all of the applicable NEC sections treat the inverter output current as a continuous current and require OCPD sizing of at least 125% of that current, unless you are using 100% rated OCPD (which don't exist at this rating). E.g. 2023 NEC 706.31(B)

Looks interesting, so does the car just output DC and one of those boxes is a special inverter for the car DC?
As an aside I am not sold on the Span panels, or specifically idea of having a circuit board with a bunch of relays acting as the 'bus bar' between the main and the branch breakers.

Yes, on the link in post #2, at the bottom you have to select the second tab (internal to the web page rendering) to see the specs on that inverter.

Sorry for the dumb questions, you mean post #5?
These 'specs' don't satisfy my curiosity:


I wonder what the DC voltage / current on the input is?
Whats the output voltage spec? Can it connect to a single phase 208/120 panel?
Seems like it works on a wide range of vehicles.
Does it use the 'standard' (non tesla) SAE J1772 or whatever car plug used for AC charging and run DC backwards?
Another aside @Chamuit 's dog looks adorable.
