'MORE' 240v power than you thought .... SUCCESS!

[hturnerfamily]

TESTED: SUCCESS!

you now have an additional 240v 20amp OUTPUT at the rear BED outlets, via a 'Y' adapter:

here's how to create MORE 240v output, via a 'Y' adapter(two 30amp 120v male to a single 50amp 240v female, using two 30amp to 20amp adapters to the BED outlets) setup....
while there is such a thing as an adapter that can go from 50amp 240v female to TWO 20amp 120v males, those are rare... since I have a camper and often use these 30amp to 20amp adapters, I had two on hand, which made this TEST easy...

It's great to find ADDITIONAL 240v output, IF you ever need it... NOW WE KNOW : )

The 240v OUTPUT verification means that you can use BOTH the onboard ProPower 30amp 240v twist-outlet, along with ANOTHER 20amp 240v output with these adapters... giving you much more 'available' 240v power, and WITHOUT having to have the HIS(Home Integration System) that is very expensive. Yes, you only have a total of 9.6kw of output, or put into 240v terms: 40 amps, but that extra 10amps might be just what you need. You can use the full 20amps from this 'new' 240v output, or you can share it with the existing 30amp output, as long as both, together, don't go over 40amps, or either exceed their 'own' limits, 30 or 20.

Here's the reason this WORKS: Ford designed the LIGHTNING with a 2.4kw 120v 20amp output, on a single inverter, with outlets within the Frunk, the Cab, AND one set in the BED.
When you 'upgrade' to the ProPower optional 9.6kw OUTPUT, you get a SECOND inverter, on a DIFFERENT phase, with the 30amp 240v twist-lock outlet, AND an additional set of 20amp 120v outlets in the BED. These 'additional' outlets are on a DIFFERENT phase from the neighboring 120v outlets, and allow this 'combining' of two 120v circuits to create the 240v output we want. THANK YOU FORD.

I believe that the 30amp twist-lock outlet, and the two 20amp outlets directly underneath are on the REAR bed inverter, and the neighboring two outlets are on the FRONT inverter, with the Cab and Frunk outlets.

CONGRATS! : ) woop!

It's not clear exactly what is plugged into / combined with what. Can you draw a simple 1-line diagram (i.e. hots only) labeling the parts?

Edit: never mind, I think I figured it out. You aren't using the L14-30 outlet at all right?

 

[chillaban]

Have you tried running anything with the combined outlet? I would worry about the truck’s extremely sensitive GFCI.

 

[Maquis]

The inverter is only 7.2 KW. If you exceed that, it will shut down.

I just demonstrated the ability to 'create' an additional 240v OUTPUT by combining two of the 20amp 120v outlets ...
yes, you 'could' use this, at the same time, as using the 30amp 240v outlet, itself, if you want to try to draw as much 240v power as possible, up to the 9.6kw max between all the outputs.

There are TWO inverters: one, 2.4kw 120v, up front for the Frunk, Cab, and inital BED 20amp outlets
and the other the rear inverter, 7.2kw 120v/240v, for the 240v 30amp outlet AND an additional set of 20amp 120v outlets... 9.6kw total.

that's possible, but since the 'Y' adapter WORKS, as far as testing it for it's 120v AND 240v combined output with the ampMeter, I would doubt that the fear of the GFCI having nuisance 'tripping' would then occur - the adapter, itself, cannot work if there is a GFCI issue...

each 20amp 120v 'separate' outlet in the BED has a 20amp to 30amp ADAPTER plugged into it...
then
each of these adapters the become the outlets that the 'Y' 30amp DUAL to 50amp 240v ADAPTER plugs into, for the single 240v output(NEMA 14-50R)...

Right. But what you’re showing here is all connected to the rear 7.2 KW inverter. Unless I misinterpreted something.

It's very important to note that you can't combine the 120V outputs of 2 inverters to get 240V power just because it's a "different phase". They need to be synchronized to be exactly (or at least very, very close to) 180deg out of phase, meaning their peaks are opposite, which is where the 240V comes from. I really doubt the 2.4 kW inverter and the 7.2 kW inverter are synchronized, but I'd love to be proven wrong on that one.

What I expect is happening here is what others have said, you've just demonstrated that the 2 sets of 120V outlets are on leg 1 and leg 2 of the split phases of the 7.2kW inverter. This is evidenced by the covers being labeled "A", "B", and "A+B".

I do NOT suggest trying to combine the Frunk or interior outlet power the way you have combined these.

 

[wiffleballpractice]

FWIW, you CAN get 9.6kW from the truck without the HIS, but 2.4kW of it must come from the 120V inverter that is provided in the Frunk or interior of the truck. A conceivable setup here might be having backup to most of your circuits from the 240V plug via a transfer switch and then powering things in your garage from the frunk. I do this, powering the the freezer, network cabinet, and garage door openers separate from the backup transfer switch.

Bed plugs are supplied by two 3.6 kW inverters. Cab and frunk are supplied from a third 2.4 kW inverter.
OPs trick does work to get you a 2nd 240 receptacle, but you are still limited to a total of 7.2kW from the rear. Here is what I get when charging our Pacifica Hybrid from the 30A plug. You can see that the Pro Power app shows the inverters maxed out.

 

[hturnerfamily]

I'm simply making the proven case that you CAN create 240v power from two of the 120v outlets... my ampMeter obviously SHOWS this is the case...

now, as to the argument of whether these two SETS of 120v 20amp outlets in the BED are 'only' from the REAR 120v/240v inverter, or whether they originate from the two DIFFERENT inverters, is up to more digging...

I may try some more TESTING today... if it's not too 'brrrrrrr' COLD!!!!

I think it's quite possible you may be right, as I've assumed that the rear 'ProPower7.2kw' 120v/240v power was from a SINGLE inverter... if that's not the case, and it's actually TWO additional 3.6kw inverters, with a circuit using those COMBINED inverter power to create 240v output, what you show and say makes sense.
Also, though, these rear outlets are just from two 'circuits', from the same LARGER inverter, mounted right on top of the rear Motor, as my own pictures show from my original 'dive' under my truck early on. I don't actually believe there are two different inverters in the rear.

We'll have to run some tests to find out...
