Already bought the Delta 2 Max (QVC deal $1249 WITH 220W Bifacial panel) Also QVC had special extra Delta 2 Max battery for $800. So $2050, no interest, 5 payments, for Delta 2 Max, EXTRA Max 2 battery + 200w bifacial solar panel. Sorry the delays are over. I’m Uber happy for what i received not only at this price, but all the features. Thanks to the solar gods!

[@grahamjgreen]

Great video! I was trying to decide if I should get the older version and save some money, or go for the latest. The update in battery technology, dual charging inputs, and longer warranty sold me on the new version. As an aside, I think the 110 outlets on the back on the unit is a feature, not a bug, as it helps reduce cable clutter.

[@kenjboyd6233]

The LFP, expandability and useful phone app made this a no-brainer choice for me. EcoFlow is on the run providing new and reliable technologies with great support. I'm selling my Jackery products and putting those resources into more EcoFlow solar panels.

[@AaronBregg]

It has been a while since I visited your channel. First and foremost, holy cow on the production value! Great job! Secondly, I just got a Delta 2 Extra Smart Battery to go with the Delta 2 I got earlier this year. Holy cow, the difference between the Goal Zero and EcoFlow products is no longer close. After 7 years of getting GZ products, I have fully bought into the EcoFlow family. As always, keep up the great work!!

[@gary860]

I think the Delta 2 Max is the best option for most people. What is really great is that you can connect two different solar arrays to it. One could be pointed more to the morning sun and the other array could be pointed to the afternoon sun. This works great if you are unable to keep the solar panels pointed at the sun. I also like that it is portable at 51 pounds instead of the heavier Delta Pro or other large generators.

I just got the Delta Max 2000 for $1,100 on Prime day. It will be my UPS in the winter and go in my trailer in the summer. I also have a dual fuel 2,500 watt generator in my trailer. It looks like running the generator for one hour a day together with the EcoFlow, will keep me powered continuously. I pretty much always camp in the forest, so solar panels aren't really viable for me.

[@EngineerSaysWhat]

Recently I had the opportunity to run the Delta 2 Max and Smart Extra Battery for a prolonged nighttime power outage. Temps were in the upper 30's. I have a gas furnace, so I only need to power the blower to heat the house. The blower spikes at about 700 watts but runs at around 300 watts. It might run about 30 minutes per hour. I also run a full size refrigerator and small chest freezer which cycle on and off as needed. Most lights in the house are LED or CFL. Under these conditions the Delta 2 Max was estimating about 11 hours of capacity. 10 hours might be more accurate if we were up and using the fridge or microwave. Previously I would power everything with a 3000 watt Honda. It would burn about 3 gallons per day. Now with the Ecoflow Dual Fuel Generator only charging the batteries twice per day I would likely burn the equivalent of about 2 gallons per day, but only running for about 4 hours instead of the Honda running all day. The batteries and dual fuel generator are also much easier to set up.

[@alexeymalafeev6167]

Todd great review! Thanks for covering this in detail. What's the best product you'd recommend for UPS like backup for a large freezer? Ie, something that will do AC passthrough when power is available, be able to support 2k+ watt surge, and not turn AC off when the battery runs out? Is it the Delta Pro? AC500 + B300S? EP900 + B500? Something else?

[@mandaa731]

Excellent video. Cheers. Assuming the batterie is full during the day then and Solar energy covers all the house electicity needs. Also the Apps us set to solely redirect Solar energy to house and batterie. What happens to the extra Solar energy which is not used?

[@eror151]

There is a workaround when it comes to also charging while driving but it involves installing a pure Sine inverter in your car and using the AC from that

[@Darock80]

Hey Todd, thanks for the review, I have been contemplating the 2k power stations for over a month now, and now Ecoflow came in like a wrecking ball. I watched your original delta max video, and this video which has helped me greatly in making up my mind. One question though, when you combined both the grid and solar, what was the highest input into the battery, that you got?

[@todd.parker]

I didn’t have time to test that yet but they claim “When combined AC and solar input is 2400W using 1800W AC input and a minimum of 600W solar input. In only 43 min get an 80% charge”

[@FFTuk]

Great review! I’m new to van life and let’s say I travel around Europe and the delta 2 max stops working. I’ve got my family with me, what do I do in terms of repairs/ replacement or back up power source whilst on the road? Thanks

[@_intrepid]

The dual PV/car input is cool but I'd love to have more 12V amperage for camper/van/overlander situations.

[@todd.parker]

Totally agree, there should be a 30A 12v output like the pro has

[@karljolley8346]

I understand using a PS to power a refrigerator during high cost grid time and charging with passthrough at low cost grid times. But what is the actual savings ? Assuming the equipment is amortized over 8 to 10 year, main unit, extra battery, solar panels, wiring and any other bits needed to connect and set up. I wonder if anyone has made a spreadsheet that could be used to balance the best equipment with a specific circumstance.

[@HansKeesom]

The workaround for the single xt60 input is simple, use a mppt and a DC-DC to charge a small 12/24 volt battery. If you buy a mppt that has a load port use that to connect your powerstation with single xt60 to. You can even programma the load port to protect the small 12/24 volt battery. As a bonus you can take your powerstation with you while still catching some solar into the 12/24 volt battery. This same idea can be used with home solar, just mppt you roof solar into the 12/24 volt battery and use that load port to, much slower transport the yield into the powerstation.

[@todd.parker]

Cool idea but definitely not simple or inexpensive

[@patpatpat999]

About noise: I'm trying to figure out what unit in the 2kWh range is quietest when USING, not charging. Any info?

[@Gman-lf5bh]

Well done video. Nice unit but disappointed there is no 30 amp outlet. My home electrical panel has a 30 amp inlet transfer for the generator back feed. Is there a way to safely configure 30 amps output from the D2Max without a dedicated 30 amp outlet?

[@todd.parker]

You can buy a 30a to standard 20a plug adapter, it will just be limited to 20a but will connect just fine

[@julious3603]

Great video!! I wonder if the DELTA 2 Max could be paired with the Ecoflow Delta 2 to create a larger system?

[@todd.parker]

They can’t really be combined but you can use one to charge the other

[@lyndsaybeck2249]

ECOFLOW DELTA 2 Max 2400Wh suggest solar charge input 500 watts. My solar panels produce 60 VDC/10 amps to the breaker box. Can I safely input from the solar breaker box two XT60 cables into the two solar charge in-ports? Enjoyed your video, appreciate your help.

[@irvinoneil]

Do you have a video showing how you setup you transfer panel with the delta 2 max or another power station that's has similar capacity?

[@todd.parker]

Sure, I have videos on the home integration kit from goal zero that is a 120v transfer panel and that works with any brand

[@denvera1g1]

I use a real UPS downstream from my older ecoflow 1300(same 30ms switch time but i swear its cloer to 300ms), as the ecoflow doesnt switch fast enough for my router/switch, my file server on the other hand seems to handle it OK but it has an overkill PSU.

[@BradLarsen-nl2pc]

Heads-up. The dual solar ports also means you can use two cigarette lighter adapters simultaneously while you're driving to charge twice as fast.

[@EdFaulknerJr]

Hi Todd, very informative review. I got interested in battery backup just last month because a solar rooftop vendor stopped by and really got my attention on the tech. My neighbor behind my house uses a generator when the power goes out (unfortunately too often in our neighborhood), and it’s annoyingly loud even over here! The EcoFlow Delta 2 Max seems like the best of consumer, but still not as powerful or convenient as the roof-mounted options - but DANG are the rooftops expensive! But it seems these consumer-level solutions also can’t handle running my AC/furnace… is that the right assessment of the current state? #sorryirambled

[@todd.parker]

If you have 240 dual phase appliances like an AC unit or well pump, most power stations can’t power those. The Delta Pro and Bluetti AC300/500 can sync a pair of units to do that but it’s large and expensive. Waiting for a one box solution…

[@HippocratesGarden]

It seems, for your pacifica, a simple double throw switch would have been a simple solution. Simple turn or throw of the switch changes from alternator to solar panel, and retain the much higher input voltage (though of course the alternator isn't going to be over 60Vdc and it's unlikely you'll hae enough panels on hand, in series in the van.

[@todd.parker]

A switch is probably better than unplugging/re-plugging but doesn't solve the issue that you'd want to charge from both the alternator and solar at the same time so the D2MAX is a nice upgrade there.

[@viking9442]

Great video! Would it be fine if I always left the Delta 2 plugged in to use the EPS feature for my PC or would this degrade the internals much faster than only turning it on when needed?

[@todd.parker]

That's no problem. When you have this plugged into the wall and plug in a PC, it actually just bypasses the inverter and feeds the power directly from the grid to your computer. When the grid power goes it, it flips a switch inside to turn on the inverter and start using the battery within 30ms so the power station isn't really getting any wear and tear in this setup.

[@HippocratesGarden]

I wonder if the xt connection is better. I purchased a Delta Pro for some friends (along with a pallet of solar panels and large spool of direct bury wire), and they have plugged in the solar, unplugged it once, and when they went to plug it in again.. the xt connector fell inside. It has been sent back and is to be replaced with new under warranty, but I've found other instances of this. One would think, for something designed to be "portable" and have solar plugged in and unplugged many times.. it would last more than a couple of connections.

[@todd.parker]

Yikes. I haven't had any loose XT connectors (or any type really) on my EcoFlow units. You must have gotten a lemon.

[@Mau105]

too me awhile to figure out which end is mc4 and which is xt60 since none of the generator companies make this clear enough. Would be as simple as labeling a pic and suggesting the 10 gauge wire for lengths over 25', which is apparently accurate. Would STILL like to know a company or link to a 50' cable xt60 to mc4 in 10 gauge. May have to buy tinned wire and solder crimp on desired couplings...

[@todd.parker]

I'd recommend these MC4 cables: amzn.to/3qkHgkA This is the cable you need to adapt to Ecoflow: us.ecoflow.com/products/solar-charging-cable?variant=39880496382025

[@markcosta2216]

Great Video. I was thinking of upgrading to the Delta 2 Max from a Goal Zero Yeti 1400 in my campervan. But on the Goal Zero I use the Anderson Power Pole DC out hooked to a fuse block. I believe its 20amps. I see no equivalent on the Ecoflow. I would plug my fridge to the cig plug but where on the Ecoflow would I power a fuse block?

[@todd.parker]

You’re right, that’s a major disadvantage. The AC300Max offers high power DC output, or the Delta Pro. Check out my Veryeah review too - they have a 30A DC option

[@thefpvlife7785]

I can bet by Black Friday and this Christmas a Delta two pro would be offered.

[@todd.parker]

Could be. I’m not sure what they would do to top the pro other than adding 240v output but we’ll see!

Impossible to get an intelligent answer from someone who does not even comprehend the question.

Hoping that Anker has some customer service though the trend is that these companies do not...

[@someoneelse7629]

I would argue that the dual solar input is an feature, if you put all of your panels in series, a partial shade on one of the panels will draw down the whole array, if you have 2 separate panel arrays one will still deliver. Also, on a camper, you could have the roof mounted array on one plug and a portable array on the other plug and use both, with different orientation you get more hours of sun Sadly there are no youtube giveaways for me living in Sweden, and it is quite expensive here.

[@todd.parker]

Yep, I agree. It’s a great feature

[@matzke089]

I think there needs to be three product lines: 1. small ultra-portable camp-fire powerstations. 2. stationary in RVs oder medium Sailboats 3. stationary household stations The Delta 2 max is to heavy for Nr1, to little Amps on the 12V DC output and to high standby loss for Nr2, to little PV-Input Voltage for Nr3. I

[@todd.parker]

I agree. They really should have included a high power DC output

[@DelmaRaySmithJr]

A simple mention of the nonlinear nature of db b is a lost opportunity, thx for the otherwise stellar production.

[@mattlynn6157]

I’m new to this but so interested. As an RV’er I’m trying to figure out why I would not do this along with my normal batteries vs upgrading to expensive batteries like battleborn.

[@todd.parker]

You can definitely use this instead of typical 12v lithium batteries + solar charger controller + inverter + etc. - the only thing is this doesn't offer high power DC outputs so if you have a fuse block that runs lots of DC appliances, it might not work for your needs. Otherwise, it's a much simpler solution.

[@SolarPowerMyRV]

This won’t last nearly as long. One part inside breaks then you lost your whole investment. Usb ports die. Tryna long term test with high loads and see how long this last there is a reason you get what you pay for

The fixed the loud fans, so that's good. But some other stuff is still annoying me long term. Outputs on the back are dumb, and the buttons to turn them on and off are not placed well and hard to feel without seeing them. Mppt and inverter are not very efficient, my Victron setup charges faster from solar and the inverter uses much less watts. Bluetooth. Hate only being able to connect with WiFi, this is supposed to be off-grid so Bluetooth makes more sense and is faster. The 12v output is not very powerful, wish we had like a 10Amp output.

I agree with most of this but the inverter is pretty darn good at 91% output and very low standby losses. You can use direct connect to use this in the road away from the internet, works great

@@Mau105 Just my 2 cents here..I get your frustration. It took me a few days to figure out whose XT-60 cable to buy to use with my Anker unit (they do not sell one, and the one they supply is not optimal for me because I do not use their panels) because I could not get an answer from anyone regarding the polarity of the connector and I did not want to destroy my inverter! Anker told me which side is positive and which is negative. I really like what they have done with this Ecoflow unit. I still prefer my Anker 767 which was initially replaced because the wiring was reversed on the AC inputs; all is well now. Their CS was great but delayed by a day each time I emailed them. An engineer replied to my questions and most of what I got from them was over my head (I am NOT an electrician) but I understand why Anker uses the technology they do. I am not pushing either brand because I think they are BOTH great products. Todd does a great job reviewing these things.

If one also owned the Ecoflow fossil fuel generator, is there a way via the app to time that to only come on during certain hours of the day?

I thought about that but since there's only one charge controller, a Y connector connects both the solar array and car charger in parallel and in that setup, the source with the lowest rated voltage determines the voltage output of the whole array. That means if I connect a car charger (12v, 8a = 92w) and a solar array (say 40v 6a = 240w), you'd end up with 12v at 14a when connected in parallel = 168w so you're better off just connecting the solar array. Two inputs are an awesome feature. www.alternative-energy-tutorials.com/solar-power/connecting-solar-panels-together.html#

[@TobyCostaRica]

@@todd.parker Is that true with a Y in series too? I figured it would add the voltage and the charge controller just pulls what’s available

[@todd.parker]

@@TobyCostaRica That article I linked covered that scenario but it's basically the opposite: amperage is limited by lowest source, voltage sums. That's why they recommend only wiring solar panels that are matched in amps/volts

[@Larksparrow]

I've read a lot about the 767 having reverse polarity issues and that Anker is still shipping units and just letting the buyer figure it out and go through the arduous process of return/exchange. I am leaning on this Delta 2 Max for my teardrop RV that has a very small window style air conditioner. Thinking my limited use of the %000btu 500w AC unit along with constant solar top-off should give me good stable power while off-grid, thoughts?

I should be able to put my 12v battleborn battery in parallel with this. The battleborn battery has an internal BMS. Should work fine, or am I missing something?

[@todd.parker]

You can connect your Battleborn through the car charger cable you attach a cigarette plug to the battery or get a ring thermal to XT60 cable. It will trickle charge the Delta at around 100w. A higher voltage battery like a 24v pack would charge at double that rate.

[@JohnBaker3000]

@@todd.parker I was planning on adding the 12v Battleborn to the side of EcoFlow Delta 2 as an expansion battery (rather than buying the EcoFlow expansion battery). Since the cable only has two connections, I assume that it is a simple + and - between the batteries, much like we already do in our van with our current LiFePO4 setup. Should work ? !

[@todd.parker]

@@JohnBaker3000 Yep, you can buy or make a cable to connect the terminals to a XT60 connector, just get the polarity right. Keep in mind this won't recharge the battery. From the Delta's perspective, it's just a DC source like a solar panel or car charger so you'll need to add a battery or solar charger to recharge the battery.

[@JohnBaker3000]

@@todd.parker I was planning on simply buying the EcoFlow Extra Battery Cable for $69 and modifying it to connect to the Battleborn. Unfortunately, it appears that the cable is a "smart" cable that includes the + and - and also six pins so that the main and extra battery communicate. Looks like I can't use the Battleborn for my purpose. I'll need to buy the EcoFlow DELTA 2 Max Smart Extra Battery ($1399) and the required special cable.

[@todd.parker]

@@JohnBaker3000 Right, you can't just splice a battery in that way but if you have batteries already you can manually pull power from them to charge the Delta and either add a AC charger or wire in a DC to DC charger to recharge the batteries if you're ok babysitting all that. The smart batteries are smart and take care of all that for you...at a price
