V2H possible with other equipment?

[123XYZ]

ISO 15118 is a family of protocols related to EV charging. Since the V2X portions of this protocol are just barely getting to be properly defined, it is very unlikely that the existing programming on our trucks will support ISO standard V2X as they sit. If we a VERY lucky, Ford/Chevy/Rivian may be able to issue an. OTA update to enable support, but I wouldn’t hold you breath waiting on that.
The way that Ford, and Chevy trigger the contacts to close and allow DC power to flow today is most certainly NOT ISO 15118.

I can't say I'm glad to know that this is the state of affairs, but I'm very happy to know better what the state of affairs is.

Thanks for sharing this information.

Thanks for the info.

I'd love to be able to use my Lightning for limited home backup power, which doesn't need to meet my full usual power usage for the whole house, just back up the most essential circuits. I'd be happy to it it by installing in the rruck the second 7.2kW inverter that is used in the 9.6kW version of Pro Power on Board if I knew that the truck's software would allow that inverter to operate. I'd also be happy to instal a residential hybrid inverter with gold features, like the ones I mentioned from Fox-ESS, if I knew of a way to get the truck to connect the battery to the CCS DC pins so that power could flow out to the inverter.

I'm disinclined to go the route of the Ford/Sunrun inverter because the cost of all the involved hardware plus installation seems unreasonable.

I'll have to look into the Pointguard DC charger as a way to connect DC from the truck battery to an inverter connected to the house through a transfer switch. If I hear people have gotten that to work, I may jump on that bandwagon. I'm a little concerned that anything marketed as a DC charger will require a large battery, a 400A+ grid connection or both, but I'm off to do my research on that.

Again, I really appreciate the information.

Edited to add: I will be VERY unsurprised if the truck throws 100 errors if there is any drawing of power from the battery through the DC charging pins other than with a Charge Station Pro and the Delta/Sunrun/Ford inverter package.

I have both the Ford Home Integration System and the Pointguard system installed now (not the V2X module yet though). I am working on getting those 2 working together and am very close.
It will be possible to get the PointGuard V2X working like the Home Integration System, with just the Pointguard inverter, the load hub (transfer switch) and V2X module. It will cost just slightly more than the HIS system + Ford Charge Station pro, but will function a lot better. That being said I would recommend also getting a battery module, so the house backup will also work when the truck is not plugged in. Like the Delta inverter, the PointGuard can take direct solar input, or use AC coupled solar, and you can go off grid for quite a while with a system like that.

I think I am going to test the PointGuard with the generator input and the ProPower onboard. Unfortunately that sounds like it wont be an option for you though.

PointGuard V2X just got approved for use in North America and is compatible (and tested) with the Lightning. I believe they opened their order banks 2 days ago. PointGuard | Energy – On Your Terms Enphase needs to catch up (system I have).

PointGuard looks promising, but the language on their website is very consistent with my understanding.

“* V2X functionality is limited by the EV's capabilities. Once the relevant standards are published, V2X feature can be upgraded through the OTA. For the official support of vehicle models and support timelines, please refer to future announcement made on the official website.”

I wouldn’t assume Enphase is too far behind. I’ve seen demos of their DC bidirectional system (working on CHaDeMO) and it is impressive. I think they are just in a holding pattern waiting for the ISO standards to be finalized and for EV manufacturers to incorporate the V2X support.

This is the CYA language as it is possible for vehicles to software prohibit this.

The NEMA standard has been published as of January. https://www.nema.org/standards/view/evse-power-export-standard

The Enphase system will be AC coupled and a separate unit. It is also still very TBD on release date.

Pointguard is DC coupled to their solar and battery has announced release date by May and is accepting orders. I know there are a few other solutions out there, but they are also TBD as far as I know.

These systems are not cheap, but they do replace your EVSE, so will be even more appealing to a new EV owner.

Do you have any links to Enphase info about an AC Bi-directional V2X system. All the information I have seen from about a year ago show a DC Bi-Directional V2X system

Perhaps you are referring to how the Enphase DC bi-directional EV charger will output AC to the grid through the use of IQ8 micro-inverters, similar to the way the current Enphase IQ batteries operate, so yes the charger will be AC coupled to the grid and DC coupled to the EV battery.

The Pointguard system look interesting for a string inverter based system with DC coupled batteries. If I wasn’t already heavily invested in a Micro-inverter based solar and battery system, it would definitely be worthy of consideration.

Yes. I was referring to how the vehicle is coupled to the stationary battery and the solar. Enphase has 3 separate units that are AC coupled. Pointguard can have all 3 in the same stack and is DC coupled.
Both Pointguard and Enphase will connect their bi-directional charger to the truck over the DC lines.

The pointguard would work well with your microinverters. I am not sure if it could work with your existing battery though. If you have the combiner it could possibly work in self-consumption only mode where the battery is only charged by solar.
I currently have both the Delta HIS inverter and a SolarEdge inverter on the pointguard load hub.
