[@luxmonday]

Wow, an actual BMS that looks good! they've done a nice job on this.... the two power resistors in series are the "pre-charge" circuit if the pack ends up low-voltage. That most likely indicates that the BMS IC is a Texas Instruments part which supports pre-charge. The secret button is likely the "wake" button for the BMS... Specific TI chips need a wake button after assembly before they start evaluating the cells. It's an assembly feature.

[@EEVblog]

That makes sense, thanks.

@@fffUUUUUU you might want to post this as a top-level comment and not under someone elses comment about something unrelated to yours.

[@LarryKapp1]

Precharge for the inverter capacitors is likely . That is so the inverter surge won't kick off the protections and bms shut down battery power. That has been an issue with some of the server rack lithium batteries but the newer ones have the precharge circuit now.

[@luxmonday]

@@LarryKapp1 Yup could be that too! TI chips such as the BQ40z80 have both pre-charge and pre-discharge functions... I think you lose one LED line if you implement pre-discharge... For BMS chips that don't have a pre-discharge function you can implement one with either a commercial surge suppressor IC (usually NFET based) or roll your own with a big PFET and an RC filter to slowly turn the gate on when it gets power.

[@zacharytaylor8523]

Actually nice to see something designed like it might actually be used in harsher environments. Damn near everything nowadays seems to be designed to only operate in a clean room. Just a little thought into things like dealing with vibration/shock and slight damp conditions would do a lot of good for most anything. Of course, for all I know designing things to be as exposed to the elements as much as possible might be in intentional.

[@FursonaNonGrata]

If it's gonna stay at home why use lipo at all? A lead acid battery is less likely to start a fire and less likely to be damaged if you discharge it too much at the same capacity, while being a lot cheaper. Of course, if weight matters then that doesn't make sense, but if you're using it as a solar/battery storage/inverter setup that won't really leave the home, why not just use car batteries?

Thanks for your excellent and detailed teardown of the EcoFlow Delta Pro. I had a problem on my solar generator and the solar input plug broke off inside of the device while I was out in the boondocks. I had no idea on how to open this up and repair the problem. Thanks to this video I was able to open it up and repair the plug without sending it to the 'service center'. You are right that those spade plugs are very loose; good to tighten them up a bit.

Thanks EEVblog , I just want to share my experience with the Delta Pro I own . Like many peoples I did the research and buy in April 2022 my first units , yes it work nice and easy . in August 2022 I buy 1 more and a Dual Hub so I can run pool pump (220v 1 Hp for 5 hrs. a day sometime at day I use it to charge my Prius Prime too ) Using 3 group of 3 solar panels ( 356 W/ 37V ) to charge my units , because location of my house I get max input 1670W from solar panels . I bough new on eBay from Ecoflow Direct ( $3600/unit ) It run for 2 weeks and error code 554 pop up NO POWE ROUT PUT . I work out with EcoFlow support ( photo + video's + Reset + update etc. ) they don't know the problem so they sent me new Dual Hub to test out and yes old Dual Hub is damage and 1 Delta Pro don't provide power out put at Infinity port . Ecoflow offer to repair but not replace for a unit that last only 2 weeks . I think this system is for back up only not reliable for off grid . I look back reply time from EF it's China office time not US time !

Nice. I switched to cut resistant gloves after a heavy cut from a computer case. Never tear something apart without them. It also helps a little against that stupid burns you get if you solder in tight spaces. ;)

[@iamdarkyoshi]

Hey Dave, as someone who works in PCB assembly, I've dealt with quite a few different flavours of conformal coat. Basically all of them will glow under UV light to aid in inspection during production. Give it a try with the shop lights out! Spooky!

[@iamdarkyoshi]

Additionally, flux remover will often dissolve the coating. The stuff we use is mostly acetone according to the MSDS, which makes sense

[@mlenstra]

@@iamdarkyoshi doesn’t acetone also end up dissolving some types of solder mask and most silk screen printing (both on PCB and IC packages)?

In some of the scenes you can actually see where the UV from the sun is illuminating the purple.

"Wasted space" on the sides is likely protection, a nice gap between outer wall and batteries for when someone inevitably smacks it, possibly even required with some home battery standard.

[@marleneberlt8251]

I had the solar plug input push in and the screws fall in. I had been aware of this problem and I believed I was taking extra care. Opened it up via your video. Saw how poorly the plug was mounted. Not saying I repaired it correctly but needed to be able to use solar. Ok. So I drilled the opening so the plug assembly is now external. Used duct tape to keep dust from falling in while I was drilling. Ok. Put back together. Plug solar in and it’s charging. Thanks 🙏🏻

but looks means nothing if you are talking about a battery. Here the e-GOLF battery died within 5 years and it looks amazing but does not work anymore even below 100.000 km It took 2,5 weeks and finally the car was back on the road . Would have cost just 8000€ to get the replacement and to exchange it, but luckily with a full VW dealer maintenance record it was 0€ Imagine your fantastic looking delta ecoflow is going dead and you have a manufacturer telling you after 1 year that it is out of warranty and that there is no battery cage as replacement and no repair shop wiling to exchange the cells? Then you are screwed cause you will not be able to build such battery on your own and exchange it cause you need the same cells. Ask delta ecoflow about the brand of the cells and its modelnumber and production week and year. Silence is what you will get from them or nice marketing buzz words without any value.

Looks nice, but I just stumbled over that there is a recall for the EcoFlow RIVER 600 MAX (a much smaller model) in the EU because of quote: "The electrical insulation as well as the clearance /creepage distances between the primary and accessible secondary circuits are not sufficient. In addition, the input protective earth is not connected to output protective earth, hence continuity of protective earth does not occur. The user could receive an electric shock from accessible (live) parts. The product does not comply with the requirements of the Low Voltage Directive nor with the European standards EN 62040-1, EN 60950-1, and EN 62368-1." Checkout European Safety Gate Alert: A12/01291/22. I don't know if Dave's unit has the same problem but if some of EcoFlow's products don't meet safety standards some caution with this one is probably advisable? It would be great if Dave could investigate clearance/creepage distances on his unit.

[@jam99]

Well, input earth and output earth appear to connect with Delta Pro, at least! EN62040-1 looks like a UPS standard (don't use this product as a UPS even though the manufacturer claims you kind of can). EN60950-1 appears to have been replaced by EN62368-1 (which the certificate of conformity on the Delta Pro claims to meet).

Personally I'm looking at getting something similar to one of these. Probably not as big but beefy enough to power a larger power tool. I do think they'll become more commonplace over time.

[@jlucasound]

And (hopefully) less expensive. Although, all things considered, it is worth it. That is a lot of power that you can take with you to somewhere remote and off grid. If you are retired and have SS and a pension, albeit small, you could squat somewhere remote, out west (US) and live off grid. A camper, a tent....

[@xNYCMarc]

Do Australians find counting to 15 to be a difficult task? It's pretty easy to tell how many cells are in this thing even without counting the balance leads. There are 15 "51RO" resisters in the balancing circuit and the component places are even numbered on the board ("NB1-NB15"). So I think it's a pretty safe bet to say there are 15 cells in the pack. Lol

[@typxxilps]

You are abolutely right cause the core value lays in the quality of the cells which they are hiding like all the other bluettie power oak crap just to make the most money out of your payment cause they can change weekly which supplier of cells is the cheapest right now. And it is the hardest to check cause that is hidden in that cage . You will not get any support by them nor replacement they will simply ignore you once it is older than 1 year . We had lost 90% in 15 months with a dead bluetti cause we could only sell it as spare parts and dead. If you are really into that aks them for the type and brand of the cells - they will not tell you. But nowadays you can check the cell cause the chinese government had enough with the chinese manufacturer and forced them to produce battery cells with a laser engraved qr code that we can decode to avoid scam. You need to know the quality of these cells - or you are screwed. Check the channel off-grid garage who had bought a SEPLOS MASON 6.9 diy kit which is a rack battery with all parts needed, just 2 hours and you have such battery, but: the cells delivered where no name and the qr code showed that they had been already 3 years old and that the terminals were spot welded so that a previous usage could have been possible - cause which company puts a battery for 3 years on its shelf to sell it old and with lower capacity than advertised. This battery kit was about 2500€ and I bet you would call it scam to get battery cells underperforming and already 3 years old. So be sceptical with all these bluetti poweroak ecoflow and whatever crap that do not tell you about their cells every tiny detail like brand, type, chemistry, cpec sheet. EVE cells for example come along with a 11 page long spec sheet and these cells do deliver, other do not.

[@IlBiggo]

@@urbiso Three-pin plugs have N/L marks inside, so no, the order IS a thing. Some devices still have neutral to chassis, I'd never swap L and N. Switch on the neutral is what I learnt a few decades ago and I've always stuck to it - I'm actually surprised that remote sockets have it reversed.

And he looked so dumfounded. He says, "well yes. Yes, I guess it would.." that was one of the only times I really felt proud for stumping my gramps. He had never thought about it that way.

A great and helpful video ! I've had this solar generator for almost 2 years now and I'm very happy with it EXCEPT that it's cooling fans are ridiculously unbearably LOUD ! It's got 5 stages: stage0: 0-120W solar input (with zero output) silent, stage1: 120-400W solar input - noticable, low rpm, stage2: 400-600W solar input - medium rpm - this should be the maximum noise lvl, stage3: 600-900W solar input - high rpm - annoyingly loud like a crowded street stage4: 900-1600W solar input - all 4 fans at maximum rpm (and/or 2000W+ output) - amazingly loud like a jet airliner !!! This is REGARDLESS of its temperature ! No matter how cold the inlet is. I've tried it outside in +5C in winter and the fans still run at max at 900W solar input and zero ouput. WHY !? The inlet temp NEVER gets above 30C why are fans running at max ? I've written to the c.support several times, no real answers, just promises to be fixed later OTA. Many firmware updates have passed and still no change. Imo the fans shouldn't even kick in below 40-45C (100F). But they run at max regardless of the inlet temp. Any idea how to solve this problem ? Often the whole house is running on this for several hours (combined with Ecoflow's smart home panel) and it's doing great except that we barely hear each other talking because of the fans. :) Pls share if you have any idea and thx for the upload ! :)

Really want one of these thongs, sounds like what I was wanting to build with big Anderson SB plugs and 12V marine batteries to chargers and inverters. I just can't justify the $3000+ cost.

[@sanchezable]

I want to use Anderson port on my pro to add dc power to my rv by tying this into my dc box. I don’t want to remove my current batteries. Would that be a problem with back feeding the delta pro with my rv batteries?

i was wondering about the stated 230V AC / 15Amps power input even before seeing that wiggly connection on the back. The standard cable plugs for that sort of connectors are rated at 10Amps only - at least for the standard ones i have seen... and thats without that bad connection on the back. plug should be: VDE 0625, EN 60 320, C14 = port with male pins // C13 = plug with female contacts All i have seen are rated up to 250V AC 10Amps (perhaps you get higher drop/heatload if soldered, but they clearly are not) EDIT !! You can actually see that it says rated for 10A 250V at the back !!! @12:36 !

little bit of a shame that the anderson power pole output is not the generally accepted configuration for amateur radio (which tends to drive most of the power pole usage in the 12v/30a segment.......

I agree completely. When he opened that cover door and I saw the wonky orientation... *groan*. When he opened up the case, though, it kind of looked like you could extract those PP connectors and reorient them into the proper (hi hi) red-right-tongue-top orientation. I sure would because I can't say I've ever seen an orientation like that for 12V DC.

Disappointed to see they didn't use solid caps in certain areas

Now the real test Dave, with the holidays coming up maybe a camping trip with the family and load this thing up. "if weather permits"

[@nicks4597]

Ordered your 121gw meter :) hope it doesnt take long

Did we find out what the mystery button is? Is it a factory reset? Anyone have info? My DeltaPro not recognizing my extra batter.

[@wesdiezy]

Awesome video, I really appreciate it. I have a question that hopefully somebody sees and can give some advice. So, I bought a delta pro used off of ebay but first thing I did was plug it in to too many solar panels in parallel, so it overloaded the DC charge circuit and now nothing lights up and it makes no noise when I push buttons. When it died, it made a pop noise and all the screens shut off, and I know for sure that the screens were working before and I had turned on the inverter previously to see if it worked. Do any of you know what might have died in my ecoflow? I'm thinking one of the fuses, maybe on the BMS or the mppt controller? Its weird though that holding the on button down does nothing at all. I thought these things had some sort of over current protection and would give an error or something instead of totally dying. If it Helps, I plugged in 4 100w 18v solar panels in parallel, thinking they were old and not outputting much. I'm willing to take the whole thing apart like you did and try to replace an obviously broken component, it would just be helpful if someone could point me in a direction to see what part I should investigate. $2000 is a lot of money to burn from just plugging something in wrong. Thanks so much to anyone that replies.

[@MrIsrael211]

I have an “overload 102” error with my pro. Where can I possibly look at?

[@InimitaPaul]

If I were to build my own 16kWh battery bank would it be possible to safely connect it to my DP?

[@Chris-rg6nm]

This is what I like to see.

[@michaelsmulsky]

Thanks for great video! Why nobody ever talks about charging current and battery degradation? When they say 3000 cycles and 80%, what charging and discharging conditions were there? And what is the optimal charge current for this unit, I guess if you charge it 3000 times with max speed, its not going to hold 80%

[@pgrvloik]

it may have its uses but I'll go for a backup gasoline generator thanks :)

[@robdavy4468]

Said they'd be a link to Everyday Astronaut's video? Also, is this an ad? I see an affiliate link on the forum post

[@EEVblog]

Will add the link. No this is not an ad, and no this is not an ad and I am not in any affiliate program. I just used the links they have me. Will correct that.

[@rabbithazel3034]

I mistakenly thought it a Redflow Ainc Bromine Jobbie as you mentioned extra bad magic smoke.
