I also really liked your very clear and thoughtful review. You brought up several points that I wouldn't have recognized until I was using one. Thanks!
Glad you found it useful. As I said in the review, it's a great product (that I still use every day) but there some things to watch out for that EcoFlow are never going to promote in their sales pitch.
Sorry for the long winded comment, but here it goes anyway .... First off - Wow, that is an impressive review video right there, very high quality and good, honest. unbiased information. Thank you! .... But, unfortunately it also confirmed my suspicions/worries about whether or not the Delta Max was going to have those same loud noise issues that the new Delta 2 units have. Hobotech & multiple other dissatisfied owners have already confirmed that fact for the D-2's.... Darn - after I cancelled my recent Delta 2 order (primarily due to the noise concern) my first thought was to wait for some price reductions, and then buy the Delta Max 2000 instead. I don't think so now. And the other thing that caught my attention in your review was the solar panel connectivity issues when it's left plugged into the panels overnight. I had seen that that was an issue with the Anker 757, but had never heard of it being a concern with any of the Ecoflow products. I have a Delta 1300, and it does not have that problem that I'm aware of. It starts delivering even very low amounts of solar (5-10w) to the power unit as soon as the morning sun hits the panels, w/o any interactions from myself whatsoever. And lastly, my Delta 1300 appears to be far less noisy (approx. 40 db when I/O loads exceed 200w) than either the Max or the D2 @ 60-65db each. As a result of all this, I am now strongly considering adding a 2nd Delta 1300 to my arsenal, and I'm also thinking of it's lack of app connectivity as somewhat of a merit rather than just as a liablity. Thanks again, and good luck on all your endeavors.
Shit. That's me back to square one . Can't have that noise, in a van converted in a camper and its seems unrefined and over priced, for what they are given. Thanks for the honesty. Saved me from been pissed off .
Yes. It seems that people are very torn on this. If you're camping and you can put it in the back of a car and just feed a cable out, you'll be fine. Equally, if you're pulling hundreds of watts, expect noise. You're never going to avoid that with current tech. However, it can be loud with fairly low draw which is a problem for me personally. It is otherwise a superb device 👍🏻
@@tdcattechThe new Delta versions, especially the Delta 2 are much quieter running (I sleep with one next to me in the car. The car fridge actually is louder). I do agree with you about the huge problem of not being able to charge any of the Delta extra battery range separately (including the new "2" versions). I often need to keep devices (such as the fridge) operating while it's connected to a battery station, at the same time charging a depleted battery via solar panels. This is just not possible with the smart battery (not so smart 😂).
I love my Delta 2000w fan and all. I never thought about the noise until I saw this review. Charges very fast when needed. Probably better on the battery if one uses it when is an emergency. Combines with 2x 220 bifacial panels and a 2200w propane generator. Bring on the hurricanes. Ecoflow thought of everything. I encourage you to look at other reviews before you walk away from this.
Not sure if this is directed at me personally but I am certainly not walking away. It’s a great, solid product. These are just some things people should be aware of. I actually charge a smaller battery from the Delta Max and use that when I need silence. The Delta does the heavier lifting.
@@tdcattechabsolutely not directed at you. Just my respectful opinion. I thought it was a good review and I am sure it took much time to put together. Thank you.
Your criticism will help improve the product. Thanks for your reviews. Ecoflow has the power kits now, and I would consider updating to that system for your whole home.
I am fine with the fan noise when the battery is being used, whether it is charged or discharged. Cooling the battery is my highest priority. Having said that, when cool, they are cool. My biggest problem is when AC-in is connected and AC-out is used. If the Delta would have a real transfer switch it would have no need for so much cooling, instead they do some kind of AC->DC->AC chain which forces the fan to start cooling. I ordered a real transfer switch and will connect my Delta 2 to the generator connection of it. 150 euro for something EcoFlow should have build in. The solar input problem you might be able to solve my using a small separate 12 volt battery and a mppt controller that has a programmable load port. I use a Victron 75 15 to charge an external 12 volt battery and when voltage on that is high enough the load port is opened and stream electricity until a certain low voltage is reached. You don't need a large 12 volt battery for that and can also use the victron Victron BlueSolar MPPT 75/10 (12/24V) which has 10 amps output. Yes external battery's...... the are expensive and have no way to charge them or use them other then connecting to the main unit.... might as well buy another unit
You're the first review to mention noise... I guess that's why all the others are reviewed with it off. The extra batteries complete rip-off; you can buy an entire new unit for the price of a battery.
Great video. It’s also useful for charging other power generators while you are using your 100v solar panels to charge the delta max. This throughput charging allows lesser powered generators to charge while you charge the `delta Max at the same time.
Been using delta max in my home office with a number of computers conected to it. The fans are alamost never on, only when its charging whicb is like 30min long and only once a day max. Can confirm, fan noise is not a problem at all for me
I completely agree about the fan noise, I emailed Ecoflow asking them if it was possible to control the fan or restrict the performance similar to what you asked them , they said it could not be done, I even moved the device from my office to another part of the house to get way from the noise, in the end I sent it back as its just to loud for my environment, I’ve bought a delta mini which is silent and I am waiting for the delta 2, hopefully it doesn’t have the same fan noise issue.
That is a real shame. It's fantastic to hear that the Delta Mini is quiet but it's also much less capable than the Max. I do hope this is improved in the new higher power models.
I've received by Delta 2 and it is much quieter, the trick is to charge it at anything below 900w, anything above that will put the fans on but nothing like the noise the Delta Max makes.
awesome review! i just received my 2 DM2's & extra battery for each. nothing you said would sway me to bail. but useful info for sure! thanks!! am i incorrect believing that the units can be charged at an EVSE? i figured i could rotate them like you said.
Thank you for this information, I have been looking at these all in one power supply options, but I have come to the conclusion that for me (in a mobile application) that a setup with separate components is a far better option, solar panels that are connected all the time/ mppt solar charger/ 240v battery charger / 2000Ah lithium battery / a generator when needed / inverter. I run on solar all day and batteries at night, with this setup I can charge out each component as required, I don’t need any firmware updates ever, also my smartphone and iPad I carry in a faraday pouch (eBay), so big brother tracking is avoided. But the worst thing about all of there’s all in ones power stations is the OUTRAGEOUS COST and don’t even talk about trying to get any sort of warranty or repairs. P.S. with this setup it is costing about £300 a year for petrol, stuff being connected to mains power 🤪.
Does newer battery lithium ion fast, generate less heat and less fan noise? And how much energy does cooling the unit drain battery..? Thanks this is an amazing video I may buy the 2000
You would be crazy to purchase a lithium ion battery powered generator at this point (unless you are looking to score a deal on an older model). LiFePO4 is the new standard and should be prioritized when selecting a new unit!
Really loud to me is my husqvarna backpack blower screaming in two stroke. My 8000 watt generac is quite loud. The delta max does sound loud, thank you for sharing that. I haven’t heard it mentioned. Sort of reminds me of a big bathroom fan maybe? I’d just leave it in the garage or other room and run a cord from it to my appliance haha.
Yes. There are ways around it and for many people the noise will not matter at all but it's worth being aware of so you can make an informed decision. That's my job 👍🏻.
Great review, I have been looking at these for a couple days and this is the first time that it being loud has really sunk in. The delta 2 is interesting, but I wanted to 2000w of the delta max. I was hoping to catch this sale, but now I don't know what I want to do....
Mains inverters always need cooling but there are good and bad ways of cooling and shifting air around. These seem to be louder than the competition. Good product though.
This review was great; thank you! Have you found any power stations that handle "passive" solar charging day to day? It seems most don't do this and it's what I am looking for in a power station.
I have the Delta pro and I like a lot of people store these things in the garage or basement by the electrical panel. Mine in the basement is no more annoying than white noise for me. There in my basement and with the fans running I could watch TV without really having to turn the volume up at all. Your recording of the noise is misleading because you probably had the mic right next to the unit. Compare this to a generator and most other units that put out this kind of power and I doubt you find anything much quieter.
Good Job! I been seen a lot reviews about those products where people are going way beyond their Wattage capacity to "prove their running power ability". In other words. This people are abusing those products specification just get viewers hits and likes on You Tube!
hi, you say solar charger is limited to 13 amps, but if you see the rear cautions says max 100v 10A, mine is a delta max and thats the same label, is anything we dont know to can go to 13 amps? thanks, regards.
Ive been wondering this for a long time before buying it, i live in a apartment so im looking for something that doesn’t make a lot of noise, is the Delta 2 quieter?
I haven't tested it but from what I have seen in other videos, no. There is little if any difference in this regard. I have since tested the Delta Mini. It's considerably quieter than this Max but it is not, as someone put it, "whisper quiet". The sound is very noticeable in a quiet environment.
the Bluetti AC200 and the Bluetti EB200(MillerTech rebranded) are quiet, original Delta 1300 is loud, Anker Powerstation II 800 is quiet, EcoFlow River 412 is quiet
That's not true I think he did a good job as far as explaining that the unit is a great unit I'm an engineer electrical engineer and I have three of the Delta Pro I have two of the Delta Max and I don't experience any of that solar charging charging from the car charging from the house Outlets I've never had this kind of issue so I don't know what this guy is speaking of I don't like to criticize people but I have not experienced any of what he is saying so you got to experience it for yourself maybe he has a bad unit
Yes! This is one of the most annoying things. You would expect it to bypass heat generating stuff when in UPS mode (AC in and fully charged) but it still comes on all the time. The best product I have used for a true UPS is this on from Anker - geni.us/solixc1000 - Though this will still power up a fan when you hit 400-500W AC bypass. That's good enough for me though. As long as it's not making a noise at 100W AC, I'm happy.
@@tdcattech Thanks a lot for sharing your experience. I want to have something for the summer seasson in very quite area and its improtant for me otherwise this will bring the hell to me :D
As a veteran of the 1st gen PS4 days, my Delta 2’s noise output is not that bad! But, then again, i only use it for car camping and emergency power outages!
Would you put the battery in the car then to keep the noise down? I must admit that I've never used this in a camping scenario but it gets pretty quiet at night and this thing whirring up in a neighbours tent would be irritating, surely? 🤷🏻♂️
@@tdcattech - Yes. I typically run it during the day to run/charge all my electrical needs. However, at night it is place in my SUV to power my ICECO fridge only! But, who knows, maybe that white noise ambience produced by those fans would lull me to sleep faster…
Yes, I have done that for a few devices. Most smart plugs won't fit directly into the device if you try to use more than one but that's no problem. I actually lean more towards avoiding the mains inverter completely due to noise and use USB, PD and DC12V for everything I can.
hi i found your review while i was looking for an ecoflow power bank we have a narrowboat so it would come in handy when we are out cruising ,but at home i have an xtool laser [120.watts ]i think its output is and a macbook pro for the software would this be suitable as i am hearing negative reviews from people saying that they need constantly charging as the unit discharges quickly [i guess it depends on what you plug into it ]so any info would be usefull as you seem to be using yours daily also things like toasters kettles air fryers have you tried these things please , take care stay safe , thanks.
No. The only input is the connection to the main battery. The charging is fairly sensible. The solar power goes into the main battery at e.g. 400W and it will split the charging so the Max will charge the spare at about 200W and itself at 200W.
It's possible to use it by connecting directly to the EcoFlow (so the EcoFlow becomes the Wi-Fi access point) but this still requires an app. It requires it to support current operating systems and exist on the app store.
@@tdcattech yea on the time remaining. I'm from South Africa so we use it for something called loadshedding, where the government has scheduled blackouts every day. Around 2 to 4 hours at a time and around 2 to 4 times a day. So this thing is keeping all my work equipment and WiFi up during these blackouts. I also had my fridge plugged into it before I moved. The battery accuracy with all my computer's off and just the WiFi and fridge on, is within 10 to 15min time remaining before it goes out. And with my computer's on its about 30min to 45min off. It's also only loud when its charging right after loadshedding and if the day didn't have any, it's only loud for like 15min a day as it just keeps itself topped up. I also have it set to not charge more than 95% and not go lower than 10%
Ypu forgot one thing - despite recharge cycle lifespan - batteries have a total lifespan. for Li-ION it is 4 years, after what they starting to degrade as hell. For LiFePo4 - it is 7 years with minor degrading after the term. So LI-ION is a waste, for long-term usage - that's why industry moving towards LiFePo4 and another chemistries & types of batteries
That seems to vary a lot depending on what you read. Many places state 5 years in a worst case scenario so likely more with sensible use. Obviously, I'm not considering cycles here.
Just waching your take on this. Like you, I wanted to leave this hooked up to Solar full term and it charge without intervention every day. I just ordered delta 2 and a spare battery in favour of returning Anker 757 as this ends up with a clicking noise on dusk and needs unplugging and refuses to charge from sun up without unplugging the xt60 and plugging it back in again but will charge at even 2 watts of a grey day. Am I wasting my time you think if the eco flow won't charge unless its getting at least 30 watts of solar?! What seemed clear is becoming a pain and more of a mind field than I thought. Your take on this would be cool... You also have me thinking should I have ordered 2 main units instead of the battery add on 🤷
@@tdcattech If you have the time to test this, do you think you mind doing a test (just a mention in the video) on battery leakage through time? Like fully charging the device and letting it sit for a month to see if the batteries hold their charge. I wouldnt know if there is a standard difference or just a normal amount on lithium ion batteries. (once saw on a package of normale rechargable AA that stated there should be 75% left after a year of sitting on a shelf, discharging through time alone)
Yes. As it has a mains in, you’d need to use the mains inverter but it only consumes 41W so you could probably run the Pioneer for at least 24 hours (factoring in losses and inefficiency). If you’d want to run speakers too, you could but that would reduce your run time.
@@tdcattechThanks for taking your time to answer. Mains inverter is that included/integrated or do i have to buy that separately ? I have 2 x JBL 310 speakrs that runs on battery so that wont be a problem.
Yes. The Delta Max has 4 mains outputs so you just plug it in and turn it on. You could run your whole setup for 8 hours+ from this (plug both your speakers into the mains too) but if you only want to power the Pioneer, a Delta Mini would do great and is much more portable.
The inverter would handle the power (even a 12,000 BTU air conditioner wouldn't need more than 1.4-1.5kW) but it wouldn't last very long. Maybe 2 hours max.
Hang on a minute, the device draws power when solar is plugged-in but not charging?! I was hoping to have it plugged into solar indefinitely at my off-grid cabin. Will need to re-think this purchase...
This is more of a problem when the batteries are already low. So if the solar input is e.g. 15W, the system will never shut down and might be using 20W just being on. This obviously leaves you with net -5W which isn't ideal, particularly if your batteries are already low. Official response from support is below. "After checking with the engineering team, the clicking sound is from the Internal buzzer. It is normal from what we know. However, we still recommend not using solar charging at night and on cloudy or rainy days, because when the unit is in a low battery and the current input power of the solar panel is very low, the unit will always be determined under charging status and does not shut down. Meanwhile, the consumption of the standby power is higher than the input power, causing the battery voltage to leak and affect the battery life. Currently, we don't have a solution for this unplugging problem, but I will send your case and feedback to the R&D team again."
Ecoflow Delta 1300watt....Buyer Beware ...It never stops charging. They don't return my e-mail. Concern that it might catch on fire. Have had it for 2 1/2 months. Think twice before spending more than $ 1,000.00 dollars. Besides I am afraid to leave it out of my sight that it might burn down my house
The Delta and Bluetti series o fproducts seem to be receiving the entire attention on youtube. Competition? If it indeed should exist it's invisible. That's always a bit suspicious of excellent media work aka propaganda.
I think it's just because they're releasing new products at the moment and, in the case of EcoFlow, do lead the field as far as spec and quality are concerned (I haven't looked at Bluetti). I just released a video on the Anker 535 PowerHouse but unfortunately it's extremely negative because it's a shockingly bad product (in my experience).
I haven't heard much about that but will investigate. The percentage on my Delta Max is a complete joke. I've calibrated it multiple times and that does seem to work. However, when I've used it for a few days (recharging partially from solar) it just drops back to total nonsense. I have run my gear for over 24 hours on 1%!!!! It has no idea where it is. I don't expect perfection in this regard, but some idea of power remaining would be nice.
@@tdcattech it’s good that it runs at 1% (even though the display is misleading). My Delta Mini seems to be shutting down according to this ridiculous time remaining. With 882 capacity it turns off in about 3 hours with 60-100 watts output. I’m very frustrated and dunno what to do😢
First I am an audio engineer. You present an unfair sound sample and a totally misleading characterization on the fans, with zero context. You might want to look at a chart of how loud things like jet planes, dishwashers, traffic, conversation and offices actually are. Jet planes are far far louder than the Delta Max, or any of the Ecoflow Deltas, the Delta's are in fact quieter than most dishwashers and air conditioners, certainly quieter than gas or propane generators. It's not like it's drowning out people talking loud, which is what you are saying when you make this unfair characterization. High power devices get hot and MUST be cooled down, and the larger the battery pack the harder this is to do. It's a big hunk of metal sitting in there. So you have to try to keep them from getting hot in the first place. If you want a lower capacity or lower powered device because they are quieter - then buy a lower power device. OR - there is this thing called "an extension cord." But it isn't about stupid software programming. It's the physics involved in power transfer. Second, overpanel your solar input. But complaining that 21W won't charge your Delta Max is absurd. At a certain point the electronics just being on use more power than the DC input, so they have to set a limit. You would do better to buy more solar panels and overpanel, you can provide more Amps than the rated DC Amps in with no problem. You only have to worry about not going over the VOC open circuit voltage, but two three times the amps is perfectly fine, and this benefits you in lower light conditions. Watts is a result, not a cause of volts x amps. Crank up the amps - it's about how how many panels you have and how you configure them. Third, yes you can leave the panels hooked up. That is fine, users do this all the time. The clicking is harmless, the relay that shuts off the solar is right at the threshold wattage where it turns the solar input off. As the sun sets, someone, somewhere in the world is going to hear the relay on their DP clicking. The advice to disconnect is only for when the Delta is NOT IN USE. Sometimes though, you may have to unplug and replug in the solar in the morning, as slow increases in wattage are not always recognized by the MPPT controller. Fourth, meters. Time remaining estimates are an educated guess, like London traffic lights a general guide only. It is not and really has no way of being a precision measurement tool. As for remaining capacity metering, this is sometimes an issue. One: a 10% difference between battery packs is considered in spec because no two battery packs are alike. Two: Firmware updates have fixed some of the balancing issues. Three; DO update your firmware. Four: Sometimes the battery packs do drift or the meters simply go stupid. This does not affect operation - but it may affect your sanity! On the facebook Ecoflow Delta group they have posted the reset and the recalibration routines. I think what happens is crap power or voltage spikes in the AC input can scramble the meters, it may help to have a power conditioner on your Delta's AC input - but I can't prove this. Fifth, "App dependence." Totally unfounded on your part, You will ALWAYS HAVE the app as it can directly connect with the Delta - no Ecoflow server or internet connection required - so there will always be connectivity even in a worse case scenario. Especially if they release the API or it gets engineered - some are already working on this with interesting results. And fear Ecoflow might disappear as a company in 5 years is also far fetched, as Ecoflow now has a multi Billion dollar valuation.and is the Industry leader and the State of The Art in Solar Generators. It's considered one of China's "Unicorn" companies and in fact on China's 681 E Shopping holiday this year, they had a million sales in the first 9 minutes, and have tripled sales yearly for the past three years. Six - yeah, right on on NCM batteries. Very few users will this make a real difference at all and calendar aging will likely obsolete the device before battery cycling. Seven - individual AC output switching. Well you could implement that with AC timers on the individual AC outputs, or even a smart home switch connected to them individually or on a power strip for remote control over the internet. Eight - The expansion battery does come with the expansion battery cable. You should join the Facebook Ecoflow Delta Series Group!
Regarding time remaining estimates not affecting operation - I have to disagree, as the device “listens” to the computer. Been using a Delta mini for 25 days and it’s already gone crazy with the meters. At first it was showing correct estimates and now it shows 2-3 hours for 60-100 watts output and TURNS OFF after this time when at 1% (I set 1% in settings). No firmware updates available so far
@@siroezhkina5865 Nah. The BMS Battery management system board is separate and has it's own control logic. In the second generation devices, they combined it with the inverter board, which is also the charging board, plugged in the wall it operates in reverse for fast charging. The output and input meters measure the inputs and outputs in the Ecoflow architecture, not power consumption. And the time remaining calculates based on what is reported to it. It does not tell the rest of the unit what to do, except when the inverter or converter boards report problems and cause protective shutdowns.
It’s all relative as I’m not giving a dB reading at 1m. They are so much louder than I expected for a device designed, in part, for e.g. night time medical equipment use. Where are you using it? Is it in an area that already has air conditioning units or similar?
Bro, I just received mine opened it very excited and plugged it in to charge it up. I thought I received a damaged model or something it's so loud while just freakin charging. Like who wants to hear that loud fan when only charging? Sorry but I'm sending it back tomorrow.
You’ll always need some cooling on a device using nearly 2kW to charge (assuming it’s set that high). I mean, it’s enough to warm the mains cable! 🙂 The problem is the cooling is so loud and it’s always there even at much lower charge rates.
Really? What are you doing with it? It’s silent if all you’re doing is charging a laptop or phone. Anything a little more will 💯 spin up those noisy fans!
Don’t buy ecoflow. I’ve had so many problems. River max units - three replacements . Delta unit has firmware update issues making the unit unusable.. I am now waiting to see if they will replace it. Not good
Currently struggling to get any reply from their support. I mean anything. They have literally disappeared and have stopped responding to any question whatsoever.
@@tdcattech great.. not what is acceptable from any type of company. Seems they are in over their heads. What country branch are you contacting ? Hope you get something resolved
support-eu - I've gone back to them multiple times, provided all information quickly (serial numbers etc) but I've got nothing. I admire smaller companies building solid products but support is so crucial to customer retention.
@@tdcattech agreed. I am a week into needing a response on how to proceed. I’ve already had hours of conversation back and fourth with them over multiple units. Not pleased is an understatement. It wouldn’t matter as much if I didn’t rely on it for all my power. (I live off the grid in the forest)
Just had a quick look at your channel. I respect what you're doing and feel somewhat inadequate sat here moaning about these products when all I'm trying to do is offset my daily usage when working at home when you're out there relying on this for your daily life! It's nice to have your perspective. 👍🏻🇸🇪
Really? I would expect it to last longer than that. What is the chance of doing a full cycle almost every single day (unless using with a PowerStream perhaps)? I just don’t think they add up as fast as people think. 🤷🏻♂️
@@tdcattech I don't trust the manufacturers figures on cycles, I've learnt the hard way that each recharge is a cycle, hope I'm wrong with these newer cells.
I will make a video and send it in I plug all types of things into my Delta Max I use it quite a bit I have the Delta Pro and with the max that he's speaking of the 2016 I don't have any noise and the fans do not continue to run maybe his settings are off or something or he doesn't know how to use the unit he seems like a very intelligent guy I am not trying to throw stones or criticize him but maybe he has a bad unit I have bought several products in the past one of the products I had to return because it did not keep a charge I will say that that's the only problem I have with Echo flow
So glad I saw this. Excellent review, saved me making an expensive mistake. The fan noise is beyond unacceptable, it would have rendered the Delta max next to useless for my needs. I will not be placing my order. Going a different road now. Many thanks for making this review, it was well balanced, told the good and the bad, the truth.
Thanks for that. I think they make solid, quality products but if you want to use this in a quiet environment, this is not the one for you. Delta Mini is quieter (but not what I would call quiet) and the Delta 2 reports seem mixed around noise but I can’t really comment as I don’t have a unit.
@@tdcattech I assume all of these Li Ion power stations or solar generators have very similar cooling requirements so fan noise is a big factor. Funny enough it is hardly mentioned in any of the main manufacturers "buy me" stuff. I might spring for a smaller capacity and much quieter Li battery unit, I am looking at power oak, but now that you have put us all staring, I am investigating the noise levels on everything first. Keep your eye on this sector because people want to know the truth and good reviewers will be in high demand going forwards. I suppose they will fix the fan noise in time, but the chemistry as it stands is what it is, temperatures must be kept down for safety. Last thing you want is a silent unit that burns the house down. regards.
Absolutely. Moving power and converting voltages etc. is just massively inefficient and creates heat. Safety has to be first. I doubt EcoFlow will like this review, even though it's largely positive but I welcome your feedback! 👍🏻
@@tdcattech This is the essence of a good reviewer, you never worry if the manufacturer likes or dislikes your review, so long as its professional, balanced and truthful, which your review absolutely was. EcoFlow know that the noise issue will put a lot off their products (like me), so they have a good incentive to keep the product safe whilst significantly reducing the aircraft hangar sound effects!
When you need power during outages, there are no questions about noise. Same for fuel generators, compare their noise levels. but yes, some vendors now care about noise as well, for example Anker with their PowerHouse series.
Hi. I have both a delta (not max) and a delta pro. I agree with you in respect of noise. I do not have problems with the solar when leaving it connected all the time, nor do the units make any noise while trying to connect. But lets be honest I am in Spain and in most cases sun is not an issue here. As for switches to the AC plugs I use remote operated plugs and that with one remote allows me to switch on and off several devices. Thank you for you review!!
EcoFlow has now got back to me about the minimum solar power issue. Apparently, the unit consumes 25-30W itself, so any solar input below this cannot be used. That seems a lot, but I guess it makes sense.
It is really noisy. There's no denying that. Safety is paramount but I really wish they could implement my 'Silent Profile' as discussed in the video. Some people say the Delta Mini is very quiet in comparison but I am yet to test that.
I saw a video testing the EPS on the new delta 2, and i saw that it was pulling in 50w while outputting 40 W. The 10W difference for the invertor/unit itself, i found very large. It would be kind of neglectable if you would use powertools and run the whole battery in like 2 hours or so (just losing 20 watts of the total of 1024 to just the unit itself) but I find it a shame if you would have a low powerdraw situation of 50 watts and it kicking in, and thus being a relative 20% of your consumption and thereby losing your potential of drawing 50watts for 20 hours and now the realistic picture being 50+10 for 16ish hours. Like you said in your video it would be great to have a limiter to not kick the fans on even above 80W, this should also be discussed to see the real WH you get out if it with this draw of power. (Excuse me my comment is based on the delta 2)

Not Delta max, but Delta 2 arrived today. Straight away I'm loving it vs the Anker 757. (12kg, not 20 kg 💪) Came 30% charged and leaving for Wales in a few hours. Charged it initially to 90 % in savagely quick time in 35 to 40 minutes on 1200 watts. It was really loud, but I didn't care as all I was bothered about was getting it charged before I go and I was in the shower anyway, then pottering about and packing up to go. Tried 600 watts, considerably quieter. Under load, also way quieter than anticipated . I plugged into solar as curiosity got the better of me. 187 watts going in in hazy sun. ANKER MAX was 160 in full sun. Happy to say completely silent taking in 187 watts. The fan did slightly kick in but I was up close and it was barely audible. Need to test if it takes in low 10 watts instead of chopping it off. Ap is brill realising WiFi and Bluetooth. Sorry to bore you, but I'm relieved... Extra battery and case apparently still on it's way, but I'm now sat in a vw camper, using it and glad to be happy with it so far👍
Not boring at all. This is exactly the feedback I was looking for. The noise issue is so subjective and people’s tolerance for fan noise varies enormously but it’s great to hear that there is a quieter mode. My Delta Max is currently charging from solar at 60W (it’s grey and miserable here in Bristol) and it’s silent 😁 🎉
Yes let me know the lowest level of solar the Delta 2 will accept. I often have 10w or so coming in and my current Anchor 535 takes in 6w 8w 10w solar no problem and over days and days it is useful. If the Delta 2 takes low level solar I'd love to know.
have to agree noise is an issue. i finish work about 2am each night and use it to power my office until 6am added a timer to the mains input so start charging from my houses solar after 9am i brought a plastic garden box lined it with car noise suppressing sheets take the edge off can watch RU-vid or a movie with it in the room power was then the issue office uses 260w. so was getting about 5 hours (haven't done your calibration) so having a 48v lithium scooter battery i rigged up a 48v to 24v 20amp converter to the xt60 increase battery life to over a day may get the extra battery and the generator in the future if needs change but working fine for now
What models are the fans? There are huge variations in the noise levels of various types of fans, even at the same output level. Are they fdb (fluid dynamic bearing) type? Is there vibration isolation?
Anyone have any tips or ideas on how to keep dust and dirt out of the outputs? I was thinking of putting in those outlet socket plugs on the AC outputs but haven't thought of anything for the rest of the unit. Any ideas?
The fans are so loud because all high frequency, low surge capacity solar generators use low cost, (cheap) high frequency, transformerless inverter technology to produce AC power. I would never install one of these high frequency inverters to power my home or RV, even in an emergency. Because of their high switching speeds, high frequency solar generators like this run much hotter than low frequency, transformer-based solar generators which makes the low cost, off spec, Chinese made components such as capacitors, diodes, resistors and ICs that are used in the cheap inverters that are used in these inverters, far more prone to early failure. Another major consideration with high frequency, transformerless solar generators is safety. Because there is no iron core AC output transformer to isolate, the DC input from the inverter's AC output, all it takes is for the AC output monitoring circuitry to fail and one of the MOSFETs in the inverter's H-Bridge circuit to short to ground, and these units can send dangerous, high voltage, high amperage DC current straight to your connected AC loads which will not only damage most AC appliances but can also set those AC appliances on fire. A far better alternative is to invest less money and purchase a hybrid, low frequency, transformer based inverter charger and an LFP battery and build your own "real" solar generator. Low frequency transformer based solar generators last many years longer than these toy high frequency solar generators, and can easily power high surge loads without being damaged and without damaging your appliances. That's why the big name brand inverter manufacturers like Schneider Electric, Magnum Energy, Outback Power, Sigineer Power, Victron Energy and others, all use a low frequency topology in their offerings. Your system will last far, far longer, it will run much cooler and can easily power high surge loads without being damaged and without damaging your appliances.
