Yeh, it's both.
It sets the solar mode which will allow the 60v 15A, but it's graduated to stop the socket from melting. So as the PV voltage drops it starts limiting the current.
I'll have to get the XT60i lead and give it good test.

There was a video on YT last year that looked into it
Of the central pin is to either POS or NEG I'll will set the mode on the EFD2.. to the car or solar modes.

The official cable looks to be about £25 which is quite a bit given the connectors are likely to be a couple of quid at most - they just seem hard to get hold of Vs the regular XT60
I really like the idea of a simple physical interlock in general - but it would be nice if you could change the mode in the settings if you knew what you were doing.

Frustratingly you see the multimeter start to give the resistance but they never let it stabilise so it's unclear if it's directly bonded or with a signal resistance - most "continuity" testing allows for small resistance

XT60 VS XT60I Fast Charge on EcoFlow. . .
the new range of EcoFlow PPP`s come with the newer XT60I connection.
this has the third pin than in other situations may be a temp sensor or data coms line.
but EF has decided to use this third pin as a cable select feature.
so they have removed the FW feature where you could select the SOLAR or CAR option.
and have moved over to the Hardware option.
the reason for this is that too many XT60 cables/plugs/sockets were melting.
+++++++++++
FYI - the current FW still have the option of current limiting the CAR input to 2/4/6/8A which is nice.
+++++++++++
i picked up some XT60I plugs . . . and decided to make up my own charger link cables
+
this is what we have, two sets,
but i only need the plug.
+
you can see the third pin in the middle.
+
the plugs are also marked for + and -
I've used some 12AWG silicone wire and SB50 Anderson conectors to make up my leads.
these will plug N play into all my kit.
previously id watched a few vids that showed genuine EF Delta2 cables and people has tested them with a meter showing.
centre pin to POS = CAR cable (Limited to 8A max)
centre pin to NEG = SOLAR cable (limited to 15A max)
..
+
a quick solder up. linking the centre pin to NEG.
add the cover. . .
then heatshrink and SB50,
that gets us a new XT60-I cable next to one of my existing regular XT60.
next bit. . .
testing the difference.

ill use this LItime lifpoe as a buffer battery, its sitting at 13.3v
plugging in the regular XT60 lead. . .
we see the EF D2M charging at 103w as expected.
which is confirmed on the APP, 103W - CAR
which is also confirmed that the unit is limiting to 8A max being drawn from the battery,
now we swap over to the XT60-I cable.
we see 185W
confirmed in the APP, which now shows 185w SOLAR
but why 185w?
well, if we look at the battery monitor. . . . . we see that its at 15A
so the Delta2 is limiting the current to 15A,. . . which at that voltage relates to 185w.
the only way now to get higher charge rate is to increase the voltage. . . (11-60v)
so lets do that. . .
I've added in a 30A charger, that will start charging the LiTime battery. . . and start to increase its voltage. .
its set to lithium profile and 30A,
the slight rise in voltage from the charger dosent do much. . . we creep up to 195W
we can see here that the 30A from the charger is being split 50/50 with the battery and EFD2,
..
30A confirmed from the IP22 charger.
++++
so thats that. . . the XT60I cable will allow an increase from 8A to 15A
++++
but i want more. . . .
ok,
well on the EFD2M we have two car/PV mppt inputs,
so what happens when we plug both cables in?
exactly as expected,
we get 190w from the XT60 + 100w from the XT60 = 290w
all confirmed on the APP,
showing the CAR and SOLAR power coming in,
+++++++++++
so basically is you want more power, you need to up the voltage ,
either with multiple solar panels in series, . . . . .
or
by using the Victron Orion 12-36v converter. . . . . . . .
or
just go out and get the new EF 800w car DC-DC charger. ( it plugs into the 48v side port )
+++++++++++
.
just one more thing on this. . .
HEAT !!
the CAR charge lead is limited to 8A, as at that point the 12v socket in the van, and plug get HOT !!
this is due to poor contact area of the 12v socket design. - it gets hot over time and will possibly melt.
so they limit the power to 8A max.
+++++++++++++++++
the XT60 connectors are rated 60A surge, and 30A continuous.
..........
so EF have decided to limit the XT60 input socket to 15A. to stop it getting too hot and melting.
...
i had mine running for 20mins while testing, and even after that short time the connecotr and feed wirers were warm to the touch.
and that was with fat 12AWG cable and using SB50 andersons.
so id imagine that the other cables, incuding the official EF SOLAR cable will prob get warmaer,
as they look like they are smaller gaude wire. . . and will soak less heat away from the connector.
...
my cable used the fatter cable, that has more bulk/mass and acts as a heatsink for the connector . . helping take the heat away.
++
so be carful doing this as a CAR charge HACK, as the voltage will allways be below 15V and the Amps will allways be 15A while charging.
and there is no way to limit in the input current - like with the CAR cable.
that means most likely constant 15A charge current.
so keep an eye of the plug/socket temps.
...
FYI. . . .
also these XT60 convectors can sufferer from loose fitment. - after extended use, or heavy handed use.
the 4x bits can be pushed together after many insertions, causing the socket to be come loose.
that caused poor connection and heat build up.
thats something to look out for. . . you can spread the pins to make a firm connection again.
..
What happens if you make up a pair of XT60i leads for that power pack and feed them from a suitable high current capable source?
Either you'll get 2 x 15A (more speed) or it will draw 15A over both of them (less heat)
Either you'll get 2 x 15A (more speed) or it will draw 15A over both of them (less heat)
the unit has twin 15A MPPTs, (the EFD2 Max) - but i only have one XT60I cable atm.

which awesome,
but as we seen, running from the car with 13.6v volt odd, we get the 15A but translates to around 195W
both inputs would be 390w.
to get the 500w/1000w we need a higher voltage source ( 500W/15A = 33v or higher. )

in my case im more that happy with the 100W / 8A trickle charge from my CAR cable on the Delta-2
and 2x100W @ 8A for the Delta-2 MAX.
as i can leave the units connected in the van 24/7 . . . so they can trickle charge 100w/hr. (100wh, ) or 2.4kwh per day from the vans lithium storage battery.
++++
in my testing the Delta2 capacity definitely drops over the day time with the loads.
but will recover over the nigh time,
the issue has always been the storage battery will eventually run out.
which is why i added solar to the storage battery. - that will increase my run time ( subject to sunshine) - but will still eventually run out. (unless you go large 400-800w solar)
but now i have the 50A DC-DC charger. . . so can run the van engine for 30mins / 1hrs and replace up to 50Ah. (650wh)
++++
the new 800W Ecoflow fast engine charger is a great addition.
and does solve the slow charging problem when off-grid.
but that's all subject to the Delta internal battery. . . . which means when long term camping you need to run the engine for a top-up.
where as the storage battery idea gets you longer runtime. - but ultimately that also needs charging.
++++
i might get the EF charger and set it up for Plug N Play use?
so i can just plug and go as needed.

Amazon Xt60i job. Removed the MC4 connectors and fitted a fuse. I did order the Ecoflow version but they emailed saying out of stock
200W Renogy panel but it wasn't connected when the screenshot was taken.
off the back of this . . . .
looks like we can get a discount code. . . 10% for my friends.
Result !!!
