Hey guess what eco float just sent me another delta pro, let's check to see if the how they fix the polarity issue on that plug all right. If you don't know what i'm talking about their pre-production units of the delta pros had an issue where this plug here was wired backwards right, the polarity was flipped, and so the viewers on my channel caught it and then uh. They said that this just was a problem that was on the pre-production version of this unit, that the production versions, it would be fixed right, and so here we are about a month later and now the production units are rolling out and they're ending up a customer's Hands, and so now they sent me a production unit. How can i tell the difference? Well, first of all, this one's all dirty because i put my hands over there, this one's still kind of - and it still has the uh the sticker here.

So this is the production unit. This is the pre-production unit, so this one i fixed it, and i showed you so let's do that test that i suggested people do. This test is pretty simple right. The neutral and the hot were backwards on this.

So this is the hot and this should be the hot. So the way you check it is using a multimeter set on ohm setting, and then you know preferably put it on the beeping thing, so you don't have to look at it. So the way you test it, you put one probe here on the on the small uh and the the pin that is closest to to the other connector right. So you put one pro there one here and if it beeps that means those two are connected.

So that means this one is the line. Originally, this was uh came wired as a neutral which is backwards right. So this now is the production unit and it should do the same thing now i fixed this one myself, but now you know: oh here we go there, we go so they fixed it. So this is the hot uh leg yeah.

This is the neutral okay. Now, let's, let's take it apart to see how they fix that, if they just just change the the wires or they change anything because remember this is pre-production. This is now production unit right and so maybe we'll see some changes inside. Let's take it apart all right, so here are some changes.

Now they put that uh. They put that glue in here right. It's like silicon uh, so that these connectors don't work themselves out when uh we'll buy vibrations and stuff right uh. I see some new gaskets in here that were not on the original unit right and so that's also maybe to eliminate vibration uh.

Maybe so they could fit better. The top could fit better and it won't rattle. There's a few changes in here uh. This cable looks different.

I don't remember what how the other one looked. I think it was all it was uh. It had shrink like this right. So now, let's look underneath.

Oh, i see look at that yeah, so they just they just rewired. It wait a minute. Wait a minute all right. This is where i am right now, so, instead, eco flow, what appears that they did is instead of flipping these two, what they did is they flip this ones so either now, both of these now both of these match, but either both of these now are wrong.

Right backwards, or both of them are right, uh, one way they could have fixed. That is by switching the polarity of this right. So then, the only thing that would be wrong would be the colors right, so the positive appears to be the line. The negative appears to be the neutral, so if this is backwards from the other unit, the pre-production unit, then that's what they did.

They flipped these. They changed this harness right and then they just so they wouldn't have to change the the length of all these right. But here is the pre-production and it appears to be the same yeah. The negative appears to be the neutral and the positive seems to be the uh line.

So these are the same so either this one - i i don't know. I guess the only way now to check is to to do the old test right here right. So this is the pre-production right and according to this one line, one orange line in the center means open ground and, of course, that's to be expected, because this thing doesn't have the the neutral bonded to the ground right. So with this little thing that it's also by the way, this came with the ecoflow delta max, which is weird that they would include that in that.

But they didn't include one in this one but anyways. I have one so then you put it in there and that what it does it bonds the neutral to the ground and see. Now we get the two amber ones uh which, if you read here, correct, wiring, nothing on this side and then two ambers right. So now let's try the production unit and see if it does the same thing all right.

So, let's start up the production unit here, boom 30. I've done nothing with it. I just took it apart: okay, uh. Let's turn on the ac.

Look at that so um, i'm gon na hook this up, but i'm gon na turn it off before. I do that because reasons to believe that it is backwards. So if i ground the line, i don't know what it's going to do. Is it going to blow this up or short it out? I don't know, but i'd rather start it and stand back.

Look at that it works, so they fixed it. They fixed it. Somehow i don't know how all i'm thinking is that maybe what they did was they just switched this and they got the inverter right the board inside there to flip and to change the polarity inside of the board. This is pretty genius now.

Why is this genius right? Because it is, was the easiest way to fix this mistake? Sure sure the cables are wrong. Maybe right the colors are wrong, but who cares about the colors nobody's gon na care right because nobody's supposed to be in there anyways right, uh and it's? Hopefully it's only gon na be in this batch on on the second batch. Here's the thing most likely by the time i cut this. This mistake, all of these hardnesses were made - maybe thousands of those right so instead of having to remake that which is going to cost a bunch of money like you know a lot of money, uh, then what they did is they did uh a hack like a Software update, i think, where they swap polarities on the inverter, and that way the only change they have to do was to change this backwards, just so that this would be matching.

The end result is the same thing is that you got correct polarity on both of these on all of these connectors and that's what you want right, the end customer at the end, all we want is just to be able to use it and not have any Problems with the polarity of this right - and they have achieved that - and they achieved that in a very clever way - and i like that see, these guys are smart. These guys are pretty smart, and here we go. We get to see a bunch of lights. Blinking inside here i've never powered this unit with this uh yeah.

With this this cover off. But here we go so there you go. I can confirm that eco flow has fixed the polarity issue that they had on the pre-production unit now on their production units right and they did it in a clever way uh. So these guys are smart.

I like this company. I, like these products, sure nothing is perfect right. They got one thing that was wrong, but they fixed it and so, as a consumer. You should not have to worry about plugging this in here or worrying about the polarity.

It's just it's just gon na be right. It's gon na be done correctly, so there you go ecoflow delta pro for the win and by the way, now that i have two units i'll be able to test the uh. Hopefully, the you know their full ups unit thing with the 240 and thing i'm hoping that they send me the right hardware. Now that i have the main two units to do that right, and so i'm gon na do that in the future i wan na.

Do it i wan na power this whole building this whole building right here with those units right here right, of course, if you think those are too expensive, which i don't agree there, these are pretty advanced pieces of equipment and stuff, but you're more like me and You're into the diy boom, i'm also going to be finishing that power wall finally uh along with all these other projects that i'm doing right. So whether you want backup, you know and do it uh as a diy project or whatever or you just want to buy a store-bought unit like this or some of the other ones that they're in there uh go for it, enjoy see you guys in the next Video bye, what no way four hundred thousand well, let's go check. How did they know you?.
