All right, this is the part i take the products that i review apart right. I do a tear down just to see how well they are on the inside and look first things, i'm seeing i'm liking right. These are a lot of metallic substructures right, which means that these products are going to be tough. If you happen to bang this thing around, if you have it in the back of the truck - and you take a turn too fast and this thing tumbles around you know it's going to get scuffed the plastic parts and maybe the corners will break and stuff.

But the internals are not going to get crushed because they have metallic right. These are aluminum custom machine. Look at that these are high quality machine parts right, and so this is pretty cool to see already off the get-go here. Let's take it apart further.

Next, let's talk about the bms: this is about the biggest bms board that i have seen and with good reason. It has to do quite a bit. It has to manage this 3.6 kilowatt hour battery, but it also has to manage two other 3.6 kilowatt hour batteries. Right, it's got expansion, one and then it's got expansion.

Two and that's what these are here. When you come to this side, then these are where you connect the expansion batteries, and so it has to manage all that current, because this battery can be at one state of charge, and then these ones that you uh introduce and connect here could be in a Different state of charge, so the this section here has to manage it, so it has to let the current flow and the energy flow from one battery to the next, so that they could all equalize and they could all work together right. So ecoflow has the smartest integration. As far as what i've seen when you connect the battery.

It doesn't matter what state of charge it is, doesn't matter, it'll, just wake up. It'll sense it it'll start charging, it it'll start discharging it and you don't have to worry about managing some extra battery. It is just becomes a part of the one system here right. So this is where all that happens here and, as you can see, there are quite quite a bit of these mosfets right.

These are the switching uh power, electronics right. This is uh the switching transistors. These are the switching transistors and that's what these do. These turn on and off uh, depending on what it wants to do, and so probably a lot of these are parallel to be able to handle the large currents that this device requires right.

This one remember it could do up to three kilowatts of energy right, and so these have to well. They have to carry all that current some diodes here, uh and then a lot of logic. This are obviously all the little resistors so that they can do. Balancing of the pack 15 cells right in the pack and then some um.

What else are here yeah? These are the large pads where those get connected on the other side, so they basically sandwich that into the board. So the crazy thing is here that this board, a pcb board, is handling quite a bit of power. Let's see if we can figure out how much power moving on the electronics. This is another section of this uh product that i think the engineers did a great thing.

This is this right. Here is the only product of this kind that has been able that has the charger and the inverter right, two of the biggest pieces of the whole system integrated into a single unit, these same mosfets, these same caps and transformers, are do this the the job right When it's charging, and also when it's discharging the battery every single other uh unit, that i've reviewed from every other company have had two sets of the of all these components right and so, therefore, that's why they're, bigger and they're heavier and they're much more complex. Now, on the downside, if one of these components right here dies, then you have your charger and your discharger go bad right, but as far as engineering and design goes, this is the way to go this. You keep this system small and light and simple right and well that you can save money, and then that means you can pass the savings on to the customers, and so this is all good all around right.

Of course. Next are the two ends here and the one side: it's there's not much going on here. It's just the ports for the expansion batteries right and then the rest is just the ac input and the solar charge. Uh input in here right, so not much going on here.

I don't really like these stupid spade connectors now remember this are supposed to carry 1800 watts of fast ac charging right and so yeah. I wish they would use something else here see how loose like that. One is, for example, right: um yeah, it's not their fault, because that's kind of the norm, that's just the standard that this ac stuff comes in, but yeah i mean something's gon na get hot on the charging. Then it's gon na be this.

Of course, it's only when it's the fast charging now, obviously on this versions, they gave us the ability to slow it down, slow it down. This is the the the button right here that you put the full charging. If you want to charge this the fastest possible, but then you should always have it at some somewhat slower speeds, because that's better for the connectors better for the batteries better for the switching power supplies over there, the charger right - and so it's just better for the Whole system to just go slower than the maximum speed. Now, on the other side, there's a lot going on over here.

There's the new ports that make this compatible with the uh, the rv right by having the 30 amp uh 12 volt port over here and, as you can see, they did that it's it's zone, dedicated connector and they have on the inside. It's got an xt 90 connector, one of the black ones and then uh on the output. It's got the power pole, anderson power, pole connector there right and then that's obviously all these other stuff. This is so you can connect your outer.

You know your remote controller right here, right, wire or uh, also wirelessly, because it's got uh uh when you put this on standby, it's supposed to turn on. I think bluetooth right, and so this is pretty cool now on this side right here. This is where the power the ac power output is, and so this is pretty interesting, because now, for the first time we have a big 30 amp max connector right, which is good for the rvs and when you look inside here, look at that they're using nice Thick wires right to connect that what are these? Are they 10 gauge? Uh? I don't know what they are, but they are. They are thick.

There are thick cables uh. I can't really see the gauge, but they look about 10 gauge or maybe more maybe maybe eight gauge uh. These are silicon wires right, so yeah. This is kind of the standard now to use high quality high temperature silicon wire on on this type of connectors.

Right here is just a regular uh, socket right that you would put in a in a wall anything they're just using the standard one which is pretty smart, because why design a custom one when you just use this and then here they're using these big, thick lugs Right here terminals right for the regular, because now these are 20 amp - they used to before they're - all like you know, 15 amp or something, but now they have the extra little notch here and that's a 20 amp and so yeah this uh. This will see quite a bit of current in there, and so that is why they did that now. This is all neatly put in here. There's a lot of stuff - that's happening here for the screen and for all the lower voltage, connectors and stuff, and they did a great job here.

It's like you know, there's a lot going on here that if you don't use good design, then it's a lot of cables, a lot of connectors a lot of stuff right and they kept it to a minimum there's. You know if you've seen the alternative to this. It's a big giant mess, but they they they're doing a good job and integrating all the stuff in here. This is a good thing all right, so this is a 48 volt battery right and it does uh continuous they're up to 36 hundred or 36 yeah 3600 watts right.

So these pads here can see up to 75 uh amps continuous, but of course, it'll do searches up to 7 000. You know 4500 to 7000 watts right, so this could see up to 100 125 short bursts, uh and all of these currents have to go through this board. This is the central. You know distribution block of this system right, and so that's what these uh pads are here, because the the current carrying traces here right this is flat stock um, those are on the other side, and so these are just to sandwich the whole thing together and that's Why this there's a big part here so yeah? This is pretty smart.

How they're doing it and pretty concise it keeps it small keeps it light, keeps it easy to uh. Well, it keeps it easy too service, because if something happens to your ecoflow, they could just send a whole new board, and then you know the customer could do it or their service center can just change. The entire board come in here. Take a few screws.

Take the panels out and then this whole board comes off uh, and so these screws are connecting all of these right and so yeah, it's easy! You take it off. You put it back on you, connect. It bam you're on your way to go because you have a brand new board that is ready to go. This is a nice little touch here, so they have these uh fans that go through here, pass through here, right and all stuff gets hot and stuff.

Well, this set of mosfets is set a little bit off to the side here, so they did. They make this little shield here they will catch some of the air about a quarter of the airflow that goes in here and then it'll direct it and make it go through these uh heat sinks here just to keep that cool in there. But look at that. That's all they have to do.

This is pretty straight forward. The cooling system is pretty pretty simple. If you can design products with this kind of simplicity, then you're going to be doing well right and, of course, you're not have to waste a bunch of time. A bunch of money and resources trying to design complex systems.

This just works. They put all the components that get hot right here and then right here, right and the stuff that doesn't get as hot and doesn't want. Then they put it in the center here. So this is just smart design.

The next board here is going to be the mppt charger. This is the solar charger and of course, they did a smart thing by putting the same box right, and so that means the same. Airflow that's going through here is cooling. These parts in here right, so this is pretty big, but the way they put it on there is pretty smart, and so it doesn't take that much room right and so yeah.

This is the mppt charger. That's also on a separate board. That means you can easily replace this if it ever goes bad.

    The DC-AC convertor seems quite anemic for it's power. At 3500W it has low number of capacitors on HV also LV, even if it has short wires from battery. In rest looks good.

  2. Avataaar/Circle Created with python_avatars DormantIdeas NIQ says:

    so, interesting, the voltage of the battery is not mentioned anywhere, but it is a 48V…
    That means it has converters to drop to the 12V and other outlets
    …gonna be more efficient on the AC side(HOBOTECH says 93%).
    …but how does it push 48V+ to charge the battery,
    does it have smart switching that converts the pack to a 12V/24V on the charge side?
    how does that work? must one have a solar array setup to higher than 48V?

  3. Avataaar/Circle Created with python_avatars Rafael Justiniano says:

    The solar conector input is it a t60 or t90 and could you connect a larger battery bank 20kw home built through that port with a dc to dc converter to regulate dc power to les tha 150 v and 10 amps.
    I want to put a small 1000w propane generator with a dc charger through that port and use the ecoflow to buffer energy spikes from larger appliances could you tests those 2 capability’s

  4. Avataaar/Circle Created with python_avatars Douglas Windsor says:

    Of course they listen to suggestions from the big 4 because if you or one of the big 4 reviewers gives a bad review it hurts their campaign and if 2 or more give a bad review they might as well shut it down you do tear down and that tells us the quality of the product now if you would just think of us financially challenged people and do a review on the entry level solar generator instead of the great reviews they get from those who don't care about how well it's built or if it only lasts a year before you have to replace the battery Duracell 1440 watt modified sine Wave inverter is under 500$ but it only charges to just over 13 volts and discharges below 11 for what I used to use them for it would have been great if it had proper charging parameters and regulated 12 Volt out nature generator 2000 watt pure sine wave inverter would be great if it had proper charging parameters and a regulated 12 Volt out for them to put proper charging parameters would cost nothing extra except for the fact they'll lose battery sales as the battery would last 5 to 8 years but because there units us sealed lead acid batteries non of the big 4 reviewers will do a review think about it with a few proper reviews maybe they would put in circuitry for a regulated 12 Volt out and add USB quick charge and type C and a programmable mppt solar charge controller they would still be affordable Skip the bills one month and I would have the money to buy one skip 2 months and I could afford the one to cut the grid it wouldn't take long to to pay for it and with a charge controller that's programmable for lithium battery I'd soon have enough money to buy a lithium battery for it to buy the unit the big 4 reviewers review my utilities would be cut off long before I could afford one as I have 2: strikes again me I'm in Canada so our price is over 25 percent higher than the state's and shipping is expensive both of these two units are not only in a price range we can afford but they are sold at Costco Home Depo and Lows so even if I have to order online they ship it to the nearest Home Depo or Lowa for either free or a reasonable price

  5. Avataaar/Circle Created with python_avatars Jaden Smith says:

    Can you test the input for wind turbines? Ecoflow has mentioned that is a new feature? Also wished you could of showed us the battery, but perhaps Ecoflow didn't want that shown yet..

  6. Avataaar/Circle Created with python_avatars Ria's Shack ham radio says:

    Love it. Have been inside my unit to check out the MPPT and shielding. Totally appreciate that they put this in a metal cage for lower RFI levels.

  7. Avataaar/Circle Created with python_avatars Talking To Cockroaches says:

    Just get a Used Chevy Volt and run an inverter off that Bitch.
    When you do a teardown, Dont say anything, and stop panning that cellphone everywhere like a kid would do. It's real annoying. Just take it all apart and label everything and then use Pictures so we can see the conponents without getting a headace. Play Live and let Die in the Background

  8. Avataaar/Circle Created with python_avatars Jimmy Jackson says:

    On that 30amp 120volt plug looks like the white wire is hooked up to the gold screw and the black to the silver screw that should be the other way around.

  9. Avataaar/Circle Created with python_avatars MrSeth166 says:

    Jehu you didn't show where the breakers are and you need to do some testing with a heater plus like on another comment we saw that the wires in the Nema 30 amp connection the wires are connected backwards…
    The 20 amps plugs are connected in the board in one circuit so the total power consumption still 20 amp maximum, some people think that every one of those receptacles are 20 amp each but the design is for 20 amp each but this doesn't mean that the equipment is gonna give you a total of 80 amps…

  10. Avataaar/Circle Created with python_avatars Robert Richmond says:

    Question, do the 115 AC outlets have individual breakers? 20 amp max each or for all four? And missing from this teardown… the batteries, lets get some info on them.

  11. Avataaar/Circle Created with python_avatars uhjyu ff says:

    The white wire on the RV receptacle should be terminated on the silver screw and the black wire should be terminated on the brass screw.

  12. Avataaar/Circle Created with python_avatars salman fisal says:

    where the fuck is battries man? what's the whole point of video without showing the main thing man? oohh wait something is fishy is this a paid promation one?
