Rivian needs to push V2H update

[Polar]

When the hardware actually exists to allow V2H - I’ll be one of the first in line to buy it.

Does anyone actually have V2H working yet? Last I heard the lightning you had to have a special charger and a bunch of other things and no one was doing it.

I realize the hardware doesn’t exist yet, but I’d love to get more communication about what testing is being done, and what the roadmap looks like.

I spent a little time on the Enphase website, and this does not look like something that will be easy to implement. It looks like it requires a solar system with the new IQ8 inverters (most solar installers are still using IQ7). So it may require a full rewrite of existing solar systems.

I’m thinking practical realities will prevent a lot of people from installing this.

Let me just dispel the notion that you need iQ8 inverters on your roof - as you do not.

Enphase being a solar company is of course going to focus on those customers - but as the Lightning proved (poorly) you do not need solar for V2H to work.

As Enphase bought ClipperCreek I am going to have the most faith in their product. My HCS40 lasted almost 10 years before I replaced it with my ChargePoint - only since I wanted the 48 amp capability. I was able to sell my HCS40 for more than I paid for it after that decade of use.

The actual Enphase bidirectional charger has IQ8 inverters on board. I can't find anything that states it would integrate with an existing system with IQ7 inverters on the roof. Communications system differs between the two versions so I wouldn't be surprised if it ended up complicated in a way that Enphase wouldn't support it without replacing existing working hardware.

Which is a different argument than "you need solar"

V2H is one of those things that falls into the I don't need it or want it category.

Here is one person's experience with Ford V2H

I’ll see if I can dig up my correspondence - but when they first released the white paper I reached out to inquire. The combiner and more so system controller will manage communication so the inverters inside the V2H charger will not be directly communicating with the array on your roof.

IIRC, RJ has said that every Rivian that has been sold has hardware compatible with V2H.

But, what about on the house side....

I have solar and battery.
Would be nice to have additional battery power.

Makes sense for you for sure! I have reliable power from grid and low cost per kwh, so not adequately motivated to add solar or off peak storage.

With enphase you will need their controller (called controller2) and their bi directional charger. The controller is the switch for the home to power from the vehicle as opposed to the grid. The controller is out and we have one installed on our home. We are waiting for the bidirectional charger which is promised to be available in 2024. The bidirectional charger will have iq8 inverters in it to convert from dc to ac.

So summary her system cost an extra $10k to do the VtoH and its worked 0% of the time and has not worked properly at the end she says don't go near it. That's kinda what i've heard to we have a lightning here at work and although it sounds cool the set up and extra cost just seem excessive.

I would rather put that 10k into a backup generator so it can run the house and charge my truck if the grid goes down.

Or a $500 manual transfer switch and an inlet plug that can be used with the 30 amp plug in the F150's bed.

Seems like there is one glaring downfall of the Rivian in the comparison discussions. In most areas they either match or exceed the CyberTruck and Lightning. But the ability to do V2H (and even V2G) is sorely still lacking in the Rivian despite promises to allow for it. Not a good look to not uphold promises. Having a proper V2H would even make the paltry 110V in the bed more palatable. Thoughts?

My thoughts: I don't care either way.
