Class Action Lawsuit - Home Integration System

Here is the thread with the YouTube. Video a few posts down.

Sorry but there is NOTHING in that thread or video that indicates or shows DC charging into the truck. In fact nothing shows any charging at all, whether it is or isn't. He's guessing and not actually saying anything factual. Furthermore, he claims his charge limit is set for 90%, discharged to 89%, and now magically at 92%. So just totally unregulated blindly dumping DC back into the truck? No. It's not. That's not happening. No system would ever be manufactured to do that. The flashing green light on the FCSP indicates quote " The station is powered by battery backup, plugged in and discharging "

Also, you're suggesting that Ford, Siemens, and Sunrun all just forgot to document this Level 3 charging function?

I find this highly unlikely. There is NOTHING onboard any of the HIS components the regulate HVDC charging. There is no level 3 charging communication between the truck and FCSP. There is no way this is possible.

The truck most likely does not do anything to explicitly support or block DC charging in the setup. However, once the truck closes the HV battery contactor (for discharging) then no comms are required to charge the battery. The Delta inverter is bidirectional so it will simply push any excess solar power back through the closed HV battery contactor to the truck.

Exactly this. The Delta inverter is a 400v system and has no issue sending energy back the the truck. The truck does not display what is going on properly but it is working. In the video he notes that it charged 4% while on the HIS off grid. It would be slower than the level 2 AC charging.

I'm aware the inverter CAN work in both directions. Just like it would with a 400vdc power wall.

What I'm saying is that no engineer with a brain would set it up to allow that. Arbitrarily pushing random excess power into the truck battery is dangerous and unrealistic. And again, where is this "feature" documented?

Assuming what the guy says is true and actually happened, that sounds like a configuration problem on the inverter since I'm not aware of any documentation for this to be enabled.

All that said, if it was mine, I'd probably try to configure it to do that, but very very carefully with safety of the truck battery in mind.

Lol ... the same engineer that decided to use Bluetooth for a critical control function?

Based on all the reports in this forum It should be clear that Ford has overlooked many things in this contraption. Having said that, I am pretty sure the truck battery BMS will still shutdown the battery if necessary to prevent overcharging related safety issues.

LOL exactly. I would hope it has some safety that will open the HV relays when the battery is full. But who knows what those conditions are.

a new FCSP with 2.112.91:2.149:1.32:1.53:0.62 software, and the newest inverter software (revision 1. if memory serves?

Here's a hint that progress is crawling along, perhaps in an effort by Ford to finally get the HIS unit out of class action territory. Prompted by @Aminorjourney's post, I took a look at my long-ignored inverter via the M Professional app and just found another inverter firmware update. I had been at 1.1.21 since October 2023 and was surprised tonight to find I'd been updated to 1.1.33 since August 2024, with 1.1.34 available when I just checked tonight:

I checked to see if there was a Delta inverter system log. The best I could come up with is, when logged into my inverter via the M Professional app, go to Menu, Analysis, Log, EVSE Log, then hit the SCAN button (top right). Here's what I get:

The first date, 6/12/2023, was the date the system was installed and rendered active by Sunrun. The 10/7/2023 date is the approximate date window that the 1.1.21 firmware self-installed based on my following post: https://www.f150lightningforum.com/...backup-power-without-sunrun.12564/post-342129. I bet 9/1/2024 was the date the inverter updated itself to firmware 1.1.33. And the date and time on 10/7/2024 is when I manually updated to 1.1.34. Would be nice to have info from Ford on what each update was supposed to do for the system...
