[@twloughlin]

Amazing. But don't forget that, when talking cost, having a solar array that can effectively charge this thing in one day is part of the investment. In the NE where I live, winter is the time when you want backup power the most, and is also the time when the sun provides the least amount of power (it's cloudy a lot here). Factor that into the cost of operating and using this beast.

[@Jasonoid]

Yes, living in an area with less sunny conditions you'll need to plan for much more solar panels to get a useful amount of power. Luckily with the high voltage input, you can use higher wattage commercial panels from Signature Solar at $0.30 cents per watt.

great video. perfect timing for me because we have some nasty weather in my area and my 6 year old was asking me this morning how we can get water if we don't have power (we can't because we have a well and no generator). our house is all electric and one of these days all add up all the loads and size out what size battery backup we would need. I would really like to have one that can run everything. we have dual heat pumps for home heating/cooling, a heat pump water heater, electric washing machine and dryer, 2 fridges, the well pump/pressure tank etc... quite the load.

[@Jasonoid]

Yes, that is quite the load for any power station. You would definitely have to chose the most important loads and just run those.... or have three of these units tied together via the smart home panel 2.

Power going in charges the power station batteries. Power going out discharges the batteries. If more power is going in, it will be a net increase. You can kinda compare that to a bank of money as power watt hours can be related to dollars in a bank.

[@wallaceharvey2574]

Great comprehensive review. I was looking at this unit and comparing it to the BLUETTI AC300/AC500 with B300 external batteries and solar panels as a potential partial whole house back-up. My biggest concern with this EcoFlow unit is its shear size and weight. When you combine this with the fact that the batteries on these both systems can only be charged and used above freezing temperatures, it can mean that you may have to move them around periodically - especially when solar charging and if you live in a colder climate. So, mobility is a concern. I would also miss the flexibility to use the external batteries connections to power and operate certain items like the BLUETTI can . It didn’t appear as though the EcoFlow units external batteries can do that - unless I missed that somehow. Overall, it looks like a nice system, but I think the BLUETTI system might be more scalable and modular for my needs - with the additional flexibility in terms of mobility of the system and better usability of the external batteries.

[@Jasonoid]

I thought I mentioned this, maybe I didn't..... the EcoFlow Ultra batteries have internal heaters so it can be charged and discharged at temps down to -4F. The size and weight are large but this unit is much more compact compared to my Bluetti AC500. The Inverter is smaller than the AC500 yet it puts out 240v and more wattage. The batteries are also more compact and offer double the capacity. The Bluetti is a great unit. I have used my AC500 for almost a year straight but this model offers quite a bit more power and features for a decent price.

[@Dragonballzgtvegeta]

Nice video! I cant wait to see it connected to a house during a power outage and its performance to run high powered appliances such as water well, septic tank, kitchen stove, microwave, full size refrigerator, small freezer, and how long the battery will last. If it could run a full day and recharge in 2 hours that would be fantastic! I think some of us would use a gas generator during a emergency to recharge this ecoflow and wonder if that would be possible and how long to fully charge. Its so expensive so these questions would make the difference as compared to cheaper brands such a Anker Solix F3800, and Zendure Superbase V.

[@larryatkins4512]

super detailed review , great job , I do have one question can you use the eco flow dual generator with this unit and do they have an adapter for that use

[@tlteal]

no, their generator won't work with this unit like the delta pro. You can plug it in but it can't / won't take full advantage of the features like the delta pro would. They honestly should have called this something else because it's not similar to the Delta Pro at all...... and only confuses people.

[@Jasonoid]

You can charge the Ultra using the EF Smart Generator if you use the AC output on the genny and connect it to the 120v 1800w input on the front of the power station. Since the internal battery voltage of the Ultra is 100v, it doesn't charge with the high powered DC output. The automatic start stop features will not work on the Ultra BUT you can still start and stop the EF Smart Generator using the EF smart app. No need to touch the generator, you can control it remotely.

[@itchyjoe]

Thank you for a very comprehensive review! To charge from a gas generator can you use the AC input port or is it necessary to use the infinity port with the dongle you showed? And does it matter if the gen is bonded or floating neutral?

[@Jasonoid]

120v AC charging is on the front of the power station with up to 1800w input. (Just like a normal power station). The 240v AC charging is via the 'infinity' port on the side of the power station using the special genny adapter. I don't think the charging source needs to be grounded. It charged successfully using multiple power stations during my testing that had open grounds.

[@keyratcane66]

I believe I am going to buy this for a fridge and an AC in the Keys.

[@adolfallesch7648]

Great Review. Best so far! Just to confirm the Solar input is "DC"? Given I have a 7.2KW Solar Array with microinverters (AC). what are my options to power the DPU? Also, could a EV (Tesla, Ford Lightning) use the infinity plug to charge the DFU? FYI, Love the Spreadsheet.

[@Jasonoid]

The solar inputs are for DC only, so if you have a net-metering solar system with micro inverters they won't be compatible with this setup. You'd have to remove the micro-inverters or install a separate solar setup with DC out. The Infinity port is meant for charging at 240v with an EV wall charger (if you have the EV charging adapter). If you have an electric car with 240v output via some sort of built in inverter, you could probably charge with the 240v 'generator' adapter.

Can this unit power a space heater for 6 to 8 hours, with the space heater being the only thing plugged in? That's the main reason I want this unit. My utilities are really low, but I need alot of heat in the winter. Thanks again!!

[@Jasonoid]

To estimate runtimes you take the total capacity of the battery, and then divide it by the wattage of your load, that will give you the runtime in hours of the power station. Example, 5000wh / 500w = 10 hours of runtime.

[@shelley131]

Well, I am not going to lie, this unit beats the pants off my jackery 500. Quick question, I noticed you stated twice that it can be charged with a 240W gas generator only. Does this mean I can not use by Honda 2200 generator, or does it mean for that port only. As always great detailed review.

[@Jasonoid]

120v AC input (via wall power or an inverter gas generator) can be connected to the front using the normal 1800 watt charging cable. The Infinity port on the side of the inverter is designed for 240v charging.

[@onefatstratcat]

We live in SoCal in a pretty small home. One standard 20 cf size fridge(w/small top freezer) and a 15 cf freezer in the garage. Lets say there is an issue and we need to run power for a few days etc... Is it possible to run the home using solar panels during the day and have enough left over from the panels to charge up the battery? Also how many panels (w/rating) would we need to do the job? We just have one small desktop computer and one 65" 4k tv in the home. Thanks....

[@Jasonoid]

If you had around 1500 watts of solar connected, that would allow you to run your load and charge the battery on a clear sunny day. The devices you listed would probably pull around 400 to 500 watts consistently.

[@tjevo4g]

Excellent review. Would love to get one, but my breaker panel is installed outdoors. Have no option of moving the EcoFlow Delta Pro Ultra indoors since my kitchen is on the other side of the wall and garage is detached. I assume the answer is no since it was not mentioned by you (and the Ecoflow has a listed operating temperature of -4F to 113F), but are there any permanent outdoor solutions to use the Pro Ultra?

The device is not meant for wet installation. However the batteries do have built in heaters so it's good for charging at low temps.

When you hooked up the ultra to wall power, 1,800 watts maximum, and had 240 volt output you showed less power going out than what was coming in. Did you test having more power going out than coming in from the wall? Thanks. My potential application is during emergencies or no solar I can hook the 1,900 watt AC (120 volt) out put from my Inoiq5 (Vehicle to Load) and take advantage of it's 77kwh battery to supply some power. This is the only system I know of that can take 120 volt AC input while also providing 240 volt output. I just don't know if the 240 volt output can be more wattage than the 120 volt input.

[@Jasonoid]

Yes, you are correct. This is the only model currently that allows for 120v input while putting out 240v. The 120v charging input can be less than the 240v output. If the input is lower, the battery will just be discharging instead of charging.

[@Mab-pw4yt]

Can you run any kind of heaters or electric owns from this?

[@Moes_Prep_and_Tech]

Question, What good use is the 240v socket if you can't run an Electric Stove/Oven with it? I just bought the DPU the other day and I'm trying to make use of the 240v socket. The only thing in my house that uses 240 is the Electric oven. I was getting ready to buy that 10 circuit transfer swith you have in this video till I found out you can't use a stove. The transfer swith I have now is small, it only has 4 circuits on it.

[@Jasonoid]

240v appliances are power hungry (40 to 50 amps each). The benefit of the 240v output is being able to power lots of 120v circuits at the same time. That's how I do it, 10 120v circuits and it's been running consistently, charging off solar since this video. I've been very impressed!

[@newguy6935]

Hi, I was ready to charge up my new EF Delta Pro Ultra using an AC receptacle. However, the AC input on the Delta Pro Ultra says 15 Amp Max. Unfortunately, all the outlets in my basement are on 20 Amp circuits. Can I charge the Delta Pro Ultra on these 20 Amp circuits or, must they be 15 Amp circuits? Does the Ultra possibly regulate the amount of Amps coming into the unit? Thanks.

[@Jasonoid]

20 amp outlets can source 2400 watts 15 amp outlets can source 1800 watts Remember this equation (Volts X Amps = watts) Since you have 20 amp outlets you have more power available than needed and you are good to go.

[@jayb3518]

If Power goes out, and drain batteries, and then power comes back on, will the Inverter power back on automatically, or do you have to actually physically turn the AC output, or inverter back on. Just thinking about an instance where you are out of town and power goes out, and it's backing up your Fridge, and batteries die before power comes back on, then power comes back and Fridge stays off until you get home to manually turn the inverter back on.

[@Jasonoid]

This features an option in the EF smart app where you can have the AC inverter always on. This allows you to enable the AC inverter as long as the battery has power. If the power station dies, once it starts charging again, it will turn the AC inverter back on.

[@jayb3518]

​@@Jasonoid thanks I should have known. Definitely looks like a winner. It does appear that the Documentation states that if you are using 240V to charge it then "it cannot output 240V", It's vaguely mentioned in the manual, and explicitly said in their FAQ section. That's kind of a bummer if you wanted to fast charge from a 240V generator while power was out and still keep lights on using the ecoflow. or maybe I am misreading it with all their "terminology" Only other question is I suspect that this thing is unbonded aka. floating neutral since if connecting to a panel or non-neutral switching transfer switch the bond would be in the main panel. but I was under the impression that when plugging devices directly into the normal 120V outlets that it should be bonded, at least that's the "safest way". I was hoping that I could do a transfer switch setup similar to yours, and always be running from the ecoflow, and in extended outages, i could connect generator to my main panel with my existing interlock setup and have a 240V charging circuit from the main panel that was always connected to the 240V charging input of the ecoflow to charge it quickly, but from the documentation I would probably have to switch bak over to "line" on the transfer switch, then stat charging it with 240V from the main panel. and as long as the 240V charging circuit is independant of the inverter output, I don't have to worry about a ground loop or anything from the main panel to the ecoflow charger, out the charger through the transfer switch back to the main panel... whew my heads swimming..lol thanks for the earlier reply. sorry for rambliing.

[@TaransWorld]

Very nice video review. If I have solar and wall power charging this and leave a couple devices plugged in 24x7, will it keep the batteries charged with solar and not use wall power unless absolutely needed. I'm looking to lower my power bill with this. Does it work like that? Thanks. :)

[@stevenblack122]

So I finally found a ham radio cross check. 2 meter 146 mhz…..another opinion on DPU to share. Another guy on a Solar platform. ( I had also called support one time and they had similar failed answers and web info is quite limited as this guy suggests and I too confirm. To bad because the specs seem good ). “ Pulled the trigger on an EcoFlow Delta Pro Ultra (DPU) and I'm kind of meh on it and unlikely to expand or integrate it into the house. I got the $1k off discount. I'd previously built (and still have) a DIY system using 400ah of SOK batteries, a Giandel inverter, and victron for the solar charge controller and shunt. I really appreciate the DIY process and plan to do a 48v system next. But I needed more capacity ASAP and the DPU looked like the most expedient option. Things I like: Well packaged Worked out of the box Battery cables are very low profile Dislikes: No real manual. All they have is the web user guide which is superficial if I'm being generous. I asked support about it and they pointed me at the web guide I was complaining about. Twice. It's reasonable to expect to be able to download a comprehensive manual for offline use and to find/search through. Radio Frequency Interference (RFI). Even when the inverter is not running, it interferes with common frequencies like 146.520MHz. I'd be more forgiving if it was when the inverter is on, but neither AC or DC are on. Turn off the DPU, emission goes away. I contacted EcoFlow support and they told me I could put it in a "faraday cage". (╯°□°)╯︵ ┻━┻ No State of Charge graph in the app. Figured if they were showing charts of Input and Output over time, they must have a SoC chart. Nope. I contacted support and twice they told me to go to the app screen with the charts, which only has input and output. SoC / shunt seems unreliable - After a full 100% charge and plenty of time to balance, I lowered the full charge level to 90%. Each night I'd run a load of about 330W AC while the input was switched off. At first it'd do a night (8 hours) and have something like 54%, which is about right for the size battery and inverter efficiency. After a few days of using it overnight and letting it charge back up to "90%", it'd go from "90%" down to "8%". Quotes to imply my skepticism of its readings. Last night I charged it back up to 100% and it ended at about 54%. So I have trouble trusting the SoC. DC output PowerPole has an annoying over-under orientation. Most DC users follow a "Red Right, Eh (A)" convention where, when looking at the powerpole, with the Anderson A in the normal upward orientation, the red positive connector is on the right. The DPU uses an over-under orientation so I'll need to remember to keep an adapter cable with it. Can't turn the unit off while it's plugged in. It just won't do it. You need to unplug or switch off the AC input in order to power down the unit. The name, "Pro Ultra", come on ;-) I could live with these frustrations more if it was a few hundred dollar small capacity product, or even mid level. But for their top of the line product, it's disappointing. If I didn't have these experiences, I'd plunk down for more batteries and the Smart Home Panel 2. As it stands, I'll probably sell it once I build a 48v DIY system.”

Excellent review, with top-notch video production, but I'm just scratching my head on this offering from Ecoflow. The rolling cart looks to be well made, but that was essential if they were going to continue to call this thing a "portable" power station. Frankly, this "Ultra" product crosses over all of the lines from being a portable product to one that is, for all reasonable intents and purposes, a stationary solution. If you're going to build a stationary solution, it is just as easy, and MUCH CHEAPER, to do so with one of the DIY-friendly, all-in-one inverter/charger products that have hit the market in the last year or two. For MY $5,800 - I'm buying two EG4 6000XP inverters and a couple of server rack batteries. For that money you would get nearly twice the inverting capability, 40% more storage, tons more PV input, and the only compromise is that it wouldn't be "portable"...but neither is this monstrosity from Ecoflow, really? There is only one possible use case where this product makes sense, and it's a stretch: If you've got a large RV and an off-grid cabin that you split time living in, this product could theoretically work for both. For any other scenario, this is just a really expensive and "pretty" solution, where a home-owner would be better served by building a normal component-based system to meet their needs.

[@Jasonoid]

While you are someone that can build a DIY setup, this unit is for people who aren't comfortable with DIY in any way. Obviously you'll save money doing any project yourself but you have to have the knowledge and tools to do it. A HUGE majority of the population is not comfortable putting together electrical components and they don't even understand how this stuff works at all. Good luck to 98% of the population 'building a normal component-based system', it's not going to happen.

Hey quick question. Is the ac 120v input working like the delta pro? If you have the charging set to 1200 and the load is 500 is the input pulling from the ac charging at 1700? Hope this makes sense. Thanks! And you can charge with 120v input while running the 240v output right?

[@Jasonoid]

Yes, it works like the Delta Pro (that's true passthrough charging). You can charge with 120v input and get 120v + 240v output at the same time.

[@jaysonstebbins2539]

@Jasonoid awesome! does it add the load to the charging speed requested for a higher total input or does the input stay the same as requested even with the load?

[@Jasonoid]

@@jaysonstebbins2539 it's your set charging speed + the load. Set to to 800 watts + 200 watt load = 1000 watts from the wall. If you change the charging speed to 1000w, it would be 1200w.

[@jaysonstebbins2539]

@Jasonoid awesome thank you! I had wished they made it as a charger like the bluetti. Maybe that's why there are 2 online ups outlets and 2 eps outlets. I'm thinking maybe the online ups ports are on a dedicated inverter only. And the incoming AC input line is to a relay to the eps AC output line like a delta pro with a charger in that line. When using 220v I could see this to be seen as half your circuits in a breaker box to be ups and the other half eps lol.

[@Jasonoid]

@jaysonstebbins2539 the 240v output works as it's own UPS. It seems independent from the 120v outputs. From my testing it's around 16ms or so. I don't really use AC charging on my unit often. It supports so much solar why use wall power when I got the solar panels to power all my loads.

This is pretty expensive compared to the EG4 stuff that's all over KZbin. Can you compare things like this and the Anker stuff to the more "traditional" systems like EG4?

[@Jasonoid]

If I had many different types of systems to compare it would be interesting to see how they would. EG4 systems are for people who are willing to build something. They have to understand wiring, fuses, and other system components. Takes experience and knowledge most people don't have. These 'all in ones' are meant for people who don't know much about electronics. The reaserch, development, and assembly work has been done so there's an extra price to pay for these units.

Just wondering about the UPS function on 240 Volt -obviously charging at 120V would require the inverter to providing a 240 Volt Split Phase output, which means the inverter is always on, regardless of what UPS mode the unit is in. If the 240V Split-Phase (Generator) (Grid?) charging input is used in UPS mode, does this supply then pass through completely as it should, with the inverter only kicking in when the Grid / Generator supply drops? Not seeing a clear explanation in the owner's manual or any review of the Ultra so far. Cheers!

[@Jasonoid]

Sometimes I charge my Ultra via a secondary power station with the AC input. I see the lights flicker as it kicks on AC charging so it appears the 240v output is also part of the UPS functionality. It's not the 0ms cutover but it's quick enough my router and PC stay powered on. So charging at 120v with 240v output does appear to work with UPS functionality.

[@aaronanderson2295]

Thanks for the reply. Feeding 120v Single Phase in and UPS 240 Split-Phase out, obviously means the inverter is always on. What happens when 240v is used as the charging input via Generator cable in)? Does the 240V pass through, with the inverter only kicking in when there is no 240V in, or is the inverter always on regardless? That's the info I'm after. Cheers!

[@Jasonoid]

@@aaronanderson2295 I haven't tested 240v generator charging with the 240v output, I don't have a large enough generator. I do know anytime you are powering a load the inverter is running in the background. It never turns off. The inverter is very efficient on this model. For example, my Bluetti AC500 uses more than twice the idle power usage and it's only a 5000w single phase inverter.

[@aaronanderson2295]

Thanks for the reply -I had a Bluetti AC300 (but want an all-in-one 240 Split-Phase unit like the Delta Pro Ultra)- in UPS Mode, the inverter ran idle in the background in UPS Mode, with up to 20 Amps (programmed in setup menu and combined with a high capacity cord) supplied to the output solely by the AC120 in. If the current draw exceeded 20 amps, or, if the 120V Grid supply in failed, then a switchover via relay would take place and the inverter would supply current up to it's rated output. Wondering if the DPUltra functions the same way with 240 Volt Grid Input (rated at 20 amps max I believe)? Great reviews BTW -always come to your channel first!

[@aaronanderson2295]

Hey Jason, thanks again for this awesome review of the Delta Pro Ultra! I wrote EcoFlow regarding the UPS function of this unit ...... unfortunately, they tell me there is no AC pass through function when using 240 Volt Charging Input -All of the AC Outlets power down when 240V is fed in for charging. This means then, that once the battery(s) is depleted, continuous AC output power as a UPS will be restricted to the max 120 Volt AC input of 1800 watts (120 x 15 amps) or 240 Volts @ 7.5 amps, assuming no solar input and 100% efficiency. It would seem then that running the Delta Pro Ultra as a full time continuous UPS @ rated output of 240 Volts / 30 amps / 7200 watts, is not possible.

Would you please try out the generator charging? The manual has a note that makes it sound like you can't use the outputs while generator charging (no smart home panel 2, just the DPU). "CAUTION Keep the AC power button off while recharging the product through a high-voltage wall outlet." Their support says this is because "Bypass Mode" isn't available when charging via 240v. Their crappy manual barely mentions bypass and doesn't give the technical details a manual for a $5k device should have.

[@Jasonoid]

I showed 120v charging while outputting 120v and 240v in the video. Johnny's weekends review of this unit also shows 240v charging while putting out both 120v and 240v. I'm currently using this as my daily driver and it's been working well. I will provide an update video down the road after it has more hours behind it.

[@unwin42]

@@Jasonoid I appreciate the reply and look forward to your longer term review. Johnny's video didn't really show it. He said it flaked out on him.

The DPU will be able to support bypass mode when using 120V to power the DPU."

But also you don't need a generator if you've got a 240v outlet you could try, like a dryer or range/oven. Usually an electric dryer is the most accessible 240v outlet in most homes. Trick might be having the right adapter to connect to an extension to go to the DPU. Good luck, I hope you find a way to test it someday.

This EcoFlow Ultra environment, while impeccably engineered on the surface, is flawed and not ready for prime time. The hardware installation and set up is simple and somewhat straight forward, but that’s where the full beauty of the design ends. The software and app that are actually responsible for insuring that you have power when the grid goes down do not deliver. The biggest issue is the parasitic draw down on the battery when the system is in idle. There are a number of functions on the app that conflict with one another, making work arounds to reduce battery drain impossible. Some app features don’t work at all. And as mentioned in another post, customer support, while courteous, is basically useless. The jury is still out to see if the software functionality is going to catch up with the hardware. I’m not holding my breath…

[@Jasonoid]

I've had this running for almost 3 months non-stop. The only ever error/failure I have had had to deal with the low-PV input. Emailing the support group they briefly pushed a new firmware to my machine and the error codes stopped happening. I don't see any conflicts in the software, it just works. The idle power usage is EXTREMELY less than my Bluetti AC500 (and that only has a 5000w 120v inverter)... I do charge the DPU off solar 95% of the time, and 5% 120vac input.
