I have a PointGuard system, which by itself is an amazing home backup. the 0ms backup time is a real thing and I can go on or off grid without even noticing.
There are 3 options I am working on as far as integration with the truck.

Option #1 is to save the money I spent on my HIS (which luckily was significantly less than most) and get it working together. I think I am close, but haven't quite gotten there yet. I need to relocate the CT meter from the original HIS to the new system.

Option #2 is to use the PointGuard generator input with the pro-power onboard. I have purchased all the materials for this, but need to install it. The nice thing is that the Pointguard will still power automatically, and I can plug the generator in for extra juice, but I can plug and unplug the truck as I desire. For reference I have my whole house on the backup including my 5 ton AC (with a soft starter). It would also allow me to use a portable generator as well if I want for some reason.

Option #3 is to get the Pointguard V2X module. I am hesitant until I exhaust all tries at #1. If I didnt already have a system, it would be a no-brainer. I am talking directly with pointguard and their distributor and the module can be ordered, but has not come in stock yet.

One nice sidenote is that Option 2 will work with both #1 or #3 at the same time for extra power if needed.

My house really only uses 6-7kW max. Right now the Pointguard with 2 batteries would cover 8kW by themselves. The generator input would add 7.2 kW from Pro Power. The truck HIS could add 9.6 kW. The PoingGuard V2X module is capable of 11kW out to AC loads, plus up to another 14kW to charge the home batteries if they are in the same stack.

Once I get this finished up I will post a lot more information in a new thread so people looking into this from scratch can see another better option. For those with HIS already I will see if our hardware can be saved to be used with something else possibly.

You can't get as much power out of the truck using that method. What is the largest 240V plug amperage, 20A? 30A? Whichever it is, it isn't anywhere close to the 100A rating of the Sunrun gateway. My system is set up to power a 100A subpanel inside my house which would likely overload the pro power plug.
Sir you're confused. Your 100A capacity transfer switch is irrelevant. The HIS can provide a maximum rate of 9.6kWH (40 amp) from the truck. The Pro Power onboard 240v outlet in the bed is 7.2kWh (30 Amp). You can supplement that using the 120v frunk outlets and some extension cords to specific devices if you really want to be creative, though most of us don't bother.

So here are your two choices today:
  1. The automatic Ford HIS with a max rate of 40 amps, except it is dysfunctional junk and doesn't work.
  2. The manual Pro Power and transfer switch (or interlock) with a max rate of 30 amps, which actually functions properly every time.

Wow! This is very concerning. I was just pricing out the HIS for my 2025 Lightning. At this stage should the HIS be avoided?
Based on my experience of a pinch over 2 years avoid it. Ford's support has done nothing in 2 years to get this working. For the last two years I have been told that it is a known problem and that a solution is coming next month, well, that was until March of 2025, they told me they will have a solution by the end of the year.

I have had Tesla Powerwalls on one house for 9 years and they have performed flawlessly. I choose to try the Ford system for the additional capacity.

The other reason to avoid Ford is the Lightning is the only vehicle that will work with the HIS.

So do your self a favor. Don't do it, and if you still want to do it, wait until Ford gets is working. The generator plug is the best solution for using a Lightning now.

in my other house, i did a 50 amp charger with a 30 amp generator plug. Powers the house perfectly through pro-power. This is what I would have done on the bigger house had I known.

Are you using a critical load panel or are you powering your entire main panel?

The HIS powers a 9.6 KW inverter, so 40A at 240V. ProPower onboard provides 30A (7.2 KW). Not a dramatic difference, certainly not $10K worth.
We lost power Monday night. I powered my 100A backup panel with ProPower. With a deep freeze, 2 fridges, lights, internet & TV, I was barely drawing 1.5 KW.

Edit….I didn’t see the response by @Runaway Tractor before I posted. He already covered this!

While I understand and agree with your point, I wanted to note that HIS and Pro Power are independent systems. Both can work at the same time providing up to 16kW (19.2 kW if you plugged in loads directly to the front as well).

That’s unfortunate. I’ve found many threads discussing the 240v 30a option. That said I’m not thrilled about it as I want a more seamless option (automatic backup) that’s not limited to 30a. It’s certainly better than nothing, but it’s more limited than I’d like for whole home backup.
I agree. That's not the system Ford advertised, the system I paid over $10K and really uglied up my house with equipment to implement. They also disconnected a small generator system I had working because Sunrun said I couldn't keep it if we installed the HIS. So now I'm left with no generator and the HIS system which doesn't work, and a bunch of useless ugly boxes on my garage.

Only if the HIS works at all!

Powering the entire main panel. It’s only a 100amp panel and doesn’t use all the spaces. Plus I know not to run certain breakers, I’m not an idiot. lol

oh, I wasn’t implying you were an idiot by any means, just asking a question. I’m researching solutions and I’m considering powering my entire main panel and just manually shutting off high load circuits that I don’t need. So that’s why I was curious on how you implemented your back-up installation.

Avoiding the HIS until (or if) it ever becomes fully functional is my recommendation.

I am preparing to install the lockout switching and a generator plug to support my backup needs.

Costs like $50 bucks. I can turn off a few breakers and live with manually connecting the truck for $9,950 bucks.

$9,950 seems just as expensive as HIS….

The $9,950 is the amount I’m saving.

I’m getting some level of power outage backup for $50. And the cost of owning my Lightning of course. 😊

Can the inverter in the HIS actually supply 100A (when it works at all)? The marketing materials available when I bought my Lightning quoted a decidedly lower figure.
