V2H possible with other equipment?

[Elctrnone]

I just received my charge station pro yesterday and was wondering if anyone has been able to use other equipment to perform the home backup power? Like the Tesla universal wall charger? I already have solar panels with a backup battery at home but Sunrun still wants to charge me for all new integration equipment. $8500-10000 total.

If your current solar/backup has generator inlet capability, you might be able to connect the ProPower to it (if your truck has ProPower, of course).
There is currently no way to access the HVB DC to power an inverter other than the SunRun system, AFAK.

ETA - I’d spend the $8500-10,000 on adding battery capacity to your current setup before I’d buy the SunRun system.

Thank you for your opinion. I have the electrician who did all the original work coming out for an estimate as well. $10000 only gets me one more Powerwall for my existing system, whereas the extended range battery in my Lightning has the capacity of around 11 of them. Have you had any experience or problems with the Sunrun system?

Like the Tesla universal wall charger?

The standard Tesla Universal Wall Charger has nothing to do with solar or backup power. All leading solar/home battery systems are proprietary including Tesla. In general, they do not support integration with third-party systems. It's a great way to lock customers in. Not sure how committed you are to the Tesla ecosystem, but the CyberTruck offers even more backup power capacty than the Ligthning and supports full integration with Tesla solar/home batter/chargers.

I have no experience with them, but if you do a quick search on this site, you’ll connect with folks who do.

I already have a Model 3 and standard wall charger. On Tesla’s store site, it says the Universal wall charger supported vehicle to home charging, for the Cybertruck only. I didn’t know if that was because it was the only vehicle they currently have that supports that feature, or if it was specific to Tesla.
I have one Tesla Powerwall with their gateway already installed, and of I can’t make the Ford work as a backup battery also, I may get the Tesla Universal charger just for the ability to link the two wall chargers together and share a circuit.

This was why I wondered about using Tesla’s Universal Wall Charger with my Lightning.
from their website:

I will post again after Monday, when I have spoken with my electrician. Their company is certified for Tesla’s solar equipment as well as multiple other brands, and they do installations for dealers and other commercial properties as well as residential work.

Just want to clarify for you that the current gen wall connectors from tesla do not PowerShare the same circuit. It is software power sharing. They still get their own individual circuit from your panel.

as far as i know, only the gen 2 wall connectors have the ability to be hooked up to a single circuit and share the power from it amongst themselves.

 

[Elctrnone]

Thank you.

Only CT will be supported initially. The special UWC version/mode for bidirectional power transfer will only support Tesla PowerShare vehicles via proprietary comms/controls. Regular charging (single direction power transfer) for third-party vehicles should still work.

 

[cwstnsko]

As others have stated, the Tesla UWC does bi-directional AC charging/V2H, but it does not apparently conform to any standard and is almost certainly entirely proprietary.
I don’t think the standards for V2H/V2G are finalized yet. Most of the solutions I’ve seen that are aligning to the standard involve DC home charging, with DC coupling to a stationary inverter. The Ford/SunRun system was essentially obsoleted the moment that the industry got in line behind NACS as the Tesla connector cannot support hybrid AC/DC systems. It‘s a bit of a long shot to expect Ford to be able to support the emerging standards via OTA, but it is possible. As far as I know the on-board charger(s) in the Ford are NOT bi-directional, so a Tesla-like solution is quite unlikely.

Oh well, thanks for the great information everyone! If my electricians have any ideas on ways to work it out, I will post them here after they visit on Monday.

 

[WonderFlea]

Any update from your electrician?
I'm supposed to be getting a FCSP in the mail in the next few days, and I was considering selling it and getting a tesla universal charger.

They are researching to see if anything can be done. Unfortunately my 2nd generation powerwall will not even accept a generator input, so I may be stuck paying the big bucks to use the Ford charge station if I want the additional backup power. I don’t often lose power where I am, but my electricity provider has a weird peak power policy where I wind up going off grid for a few hours per day, several times per month to avoid paying 34 DOLLARS per kilowatt hour during that peak. When the air conditioner is running along with the pool pump, I can go through one powerwall of storage rather quickly.

 

[Mr. T]

I’ve been doing some research on this as I’ve been looking to get a solar setup and want to use the Lightning bidirectionallly as a battery in the evenings so I can truly live independent of the grid. Enphase is suppose to be releasing a bidirectional charger that can do this while also automatically charging your truck with any excess solar during the day.
