Home integration system

I believe Sunrun doesn't do it any more. I believe Ford has switched to using QMerit.

There are other systems that you can use with your truck, but not necessarily the Charge Station Pro.
For what its worth, the Ford/Sunrun system does work and is supported, but it is not necessarily for the faint of heart to do so, and does work better for the DIY electrical inclined. I would not recommend even trying it at all if you would have to 100% rely on others to troubleshoot the issues it will have. It also relies on having newest firmware in the truck, which can be a huge issue in of itself.

That being said if you want to buy a small home battery and also augment with your truck, the PointGuard and Franklin systems have working generator inputs that can work with your ProPower onboard if you have it. They work well with AC coupled existing solar as well.
I believe SolArk also has a generator input as well. I am not sure if EG4 would have the support.


PointGuard does actually have a V2X charger that can be purchased with or instead of the battery, but you would no longer need your Charge Station Pro, so it is extra investment. So far they are the only ones on the market with a true V2H solution other than the Delta system used by Ford and GM.

I have both the PointGuard and the Ford HIS/Sunrun system. I have a PointGuard with truck writeup on a separate topic. It is similar to others with their Generator inputs, but this works seamlessly and can use your solar power even off grid with the truck like the Ford system does.

Well your level of expertise is above my understanding and unfortunately all these solar companies seem to be limited in the capabilities of V2H systems. Thanks for the information! I just really want to power my house when we lose power and be able to power my truck with my solar panels during the day or if we have to power. Use the back of the truck to power the house and the solar panels to power the truck. I don’t think it’s too much to ask)))

As others noted, I would strongly advise against using the Sunrun HIS. I have read and seen several YouTube videos of how poorly it works. Supposedly Enphase is coming out with a vehicle to home/grid charger. But it’s been promised for quite a while now and no new news on it. Last I saw was that it’s been pushed to 2026. https://enphase.com/ev-chargers/bidirectional

Thanks! I guess I’ll have to wait for something better!

This isn't that difficult to set up, but devils and details and all that.

I have ~10 kW on the roof and a 10kWh battery on the wall. When we lose power (not infrequently during the winter months) the battery kicks in automatically. It will hold up everything important in the house for 12+ hours. (I don't have the EVSEs on the backup panel.)

Here's the rub... we're on a well and it is on a separate panel in the pump house, so we don't have water (read: toilets) when the grid is out. Hence, I had a manual transfer switch with a generator plug installed upstream of everything else. This allows me use the truck or a portable generator to power the house and the well simultaneously. Except that the solar power controller "sees" that as grid power being back online. If the panels on the roof were to kick in while the generator is connected, the solar system will back feed to "the grid" with any excess power. I don't think the generator, be it the truck or the portable, would like that very much.

Prolonged power outages really only occur here when there are several feet of snow on the roof, so the solar panels don't come into play. Just the same, I'm *extremely* mindful of how/when I switch to using the truck to power everything.

Like I said, you can pretty easily design a system to do what you want. We practically never pay to charge the trucks for about 6 months of the year, and we have enough battery capacity to run everything for days and days when the power lines are down. But it isn't automatic, and it certainly isn't foolproof.

Definitely disconnect grid-tied inverters when a generator or PPOB is connected or you risk damaging them. Depending on the installation, it should be easy to disconnect the GTI's via a breaker or two before you connect a generator or PPOB via transfer switch.
