I know you’re so tired of talking about solar generators but I learn something new each time. Maybe I’m a slow learner. 🤣

Thank you for this review. Says us potential buyers a lot of time in sorting through all the specs and details. Keep up the good work. Thank you.

Please do more of these reviews and comparisons, I planning on buying a solar generator and solar panels and your reviews are very helpful.

Great Vid❗ I have an EcoFlow Delta 1300 and am using two Off Grid Trek 200 watt solar blankets as listed in the description. They are amazing. Plus they work in low light which wasn't mentioned. I did a video about using them in poor conditions and cable hook up. Off Grid Trek really helped me out after the freeze here in Texas. Customer service blew me away. I called twice with questions and both times Rene the owner answered the phone.

I have an Ecoflow Delta Pro that I bought after using your spreadsheet. I like it, the solar panels are heavy for me to move. I'm happy that I have it and hope to get 2 more panels and the solar panel tracker thing.

I am currently researching these as I am ready to upgrade from my little Jackery; thank you for all the work you have put into this! My biggest concern with the Ecoflow units is the poor efficiency. I’m leaning toward the Pecron due to the cost difference from other comparable units. I would not buy another Jackery unit only because of the battery technology; they have just not advanced their technology but still want to charge the highest price. Thanks again Kris.

I have a 300 watt Enginstar but no panels lol. Could barely save for the Solar Generator. But am proud of myself that I was able to do that. 🙏 for panels. It's amazing how many demonstrations that you do! I know it's a job but ThsnknYou for your time. This is a great solar generator. Stay Safe God Bless.

A great and honest review, certainly not nearly as "rosey" as some other reviews. I was considering this as a backup for my refrigerator, but dropped it for the EPS inconsistancies between multiple reviewers, dropping solar completely when AC is present (no dual charging), and pretty low AC efficiency when compared to other EcoFlow products. Still quite a bit of bang for the buck though and continuing the trend that the Bluetti EB3A started with a large inverter with a smaller battery. Thanks!

I bought the Delta 1300, 1260 Wh battery. Just getting in to this. I am saving up and buying them as I can pay for them, so hopefully I can cashflow a decent system where I could run most of my systems in the event of a sustained power outage. Just ordered a EcoFlow 175 watt solar panel. Thank you for the info!

Thanks for all you do for the community.

Love the opening quote! LOL Thanks for all the details you have given us on a wide variety of the solar generators. Truely appreciate it.

I have been researching solar generators for over a year and am leaning towards the Generark (now known as Geneverse.) I am looking to the HomePower2 generator. The solar panels are all weather, it also has a 5 year warranty, their website also states that when fully charged this generator can store and hold the power for at least a year. So far this one sounds amazing and has great reviews. Have you or anyone on your channel tried this generator? Would be great to hear a personal review. Thank you for this info in today’s review, I was actually going to look into this company as I just learned of them, but with info received I’ll pass.

The first thing that brought the Delta 2 down for me was that in order to get AC power out, I have to find the inverter button on the back of the unit! It can be hidden there, but the corresponding button should also be on the front panel, because I don't want to turn the device constantly and I don't want to go around it myself. I want that when I'm not doing anything with the device, I press the button on the front panel to turn the device OFF. So then, when I want to turn on the device, I have to press the front first and then the back. This is insane! Another thing that lowers my score further is that the device has only two fan positions for AC charging. Full blast for over 900W charging and slightly lower blast for up to 900W charging power. Why didn't they make this smarter so that the fan works to provide the actual cooling demand - not with excessive power and noise! You may very well want to charge with a slower and quieter fan, but even if I choose only 200W charging power, the fan still works as much as with 900W power. Crazy again!

My biggest issue with using these units as preps is that all lithium battery technologies recommends storing at less than 50% charge. So, you have to choose whether to only have 50% of your stated energy available when crisis hits, or damage the batteries inside by keeping them fully charged, or use them regularly. VERY FEW people are aware of this when buying these as emergency preps.

I got the 220 solar panel for this generator. Took me 3 days to charge it to 100% via solar and I used it to see how it charges my hybrid. Took me 3 days to charge the ECOFLOW only to charge my car up to 4 miles. (My car normally gives me anywhere from 43-53 miles of EV.)

Last weeks video really helped me clearly understand what I need to look for

Hi now that I see your spreadsheet. I know I can't afford those. Thats so sad that items we will need in emergencies. Some of us can't get. I will still be watching you... have great day

These are neat little portable devices. I jumped ahead and DIY'd an off-grid solution with 4Kw of panels, an 8Kw LF split phase inverter, and 20KwH of rack mount batteries. Not portable, but I don't have a cabin anywhere. Maybe a portable bug out EcoFlow in the future. Cheers

Just bought one during Amazon Prime Days for $479 and free shipping. Note, there are no returns unless it is damaged as it qualifies as "hazardous material". I sure hope I like it!

As always great video Kris I very much appreciate the time you put into these videos.

I think the reason why the AC efficiency is relatively low is that the unit supports extension batteries. Since all AC output is from the main unit, it requires a bigger inverter to deal with both main battery and extension batteries.

Nice job Kris! Really like the expansion capabilities so you can buy in and grow your capacity as your income and needs dictate

Thanks for bringing more great content to the community

A very nice review covering most of the features. One bit of information missing is how much power it eats plugged into the AC mains. With all outputs off and battery fully charged it uses over 15 Watts all the time. With AC output on this goes up to 17 Watts again with nothing plugged in. This makes it an expensive solution for the UPS function. A video on the use of the control schedules would be nice and they only seem to keep working if unit always powered turning the charging and setting output times.

I purchased one of these and had problems with it out of the box. I spent almost 2 months jumping through there hoops to diagnose prior to them telling me to return. They diagnosed it as a faulty battery. I was informed that they would send me a refurbished replacement. I questioned them about this and they informed me after 30 days they won’t give a new one. So wondering what is the point having a 5 year warranty?

I have a 100 dollar ecoflow gift card. Bought the delta 2 for 599. So pretty much paid 499 after gift card. Happy with my purchase. Works well with my wave.

These black friday deals are insane with EcoFlow. Purchased the Delta 2 with panels. I'm excited.

Thanks Kris for another very informative effort on our behalf!

Hi from Syracuse NY brother and everyone else and thank you for sharing everything

The 3000 charge cycles takes the cake. It will certainly last for more than 10 years.

Thanks for the review. Just ordered one even though there maybe better options. I just love the 3000+ cycles. I can see this lasting me the next decade. Also the option to expand is a great draw.

Very good video. I love your work on the spread sheet. Its nice to see a fair and balanced review.

Based on your data...seems pecron e2000lfp is solid option for the price, solar input, and efficiency.

I just purchased this with 400 watt solar panel and Delta 2 extra battery mainly for fridge and or freezer. just under $3000. Hope I did well. I am not very tech savvy. a friend will help me to set it up.

“If I have to do one more solar generator review, I’ll kill myself.” -Probably not Abe Lincoln 😂

Prefer the Deltaflow products and company better than Bluetti because of their customer service. Anything goes wrong you actually speak to someone.

You should add a column that takes into account the cycle count for each battery. It seems like you are paying more for the EcoFlow, but when you compare the lifecycle of an LFP battery, it gets 5 to 8 times more usable life, so you are actually getting more bang for you buck than one that has only a 500 or 800 cycle life.

To all potential buyers, please avoid buying Ecoflow products. I recently cancelled my 2 orders of Ecoflow Delta 2. They are refusing to refund me. I've never received the products since they have recalled the shipment. I felt robbed :( Just a public service to all potential buyers.

Thank you for the review!!

I have 2 days to decide between the delta 2 and blueti ac 180 both on sale for the same price for 2 more days. Both have virtually the same spec

Other reviews show over 80% capacity. The PS has been available for $420-430 recently. 😊

It definitely is better than most of the other power stations, Nothing charges faster.

Yesterday I purchased the Delta 2 and the extra battery as a combo package for $1049. I've got to set up a small solar panel system yet. Hopefully it will be enough to keep my refrigerator and small chest freezer going in case of emergency.

Late comment: thanks for the great review. I suspect the efficiency has more to do with the actual capacity of the battery than conversion efficiency. At 1800 W, 75% efficiency means you’re dissipating 450W into the environment. That seems high. more likely it’s really only an 850 or 900 watt hour battery

I hope the Delta Max family is upgrading to Lithium Iron Phosphate. The main unit, battery (hopefully upgraded to LiFePO) and smart generator would be a great solution for the average user. I use an AC200 Max, but the ecosystem from Ecoflow is vastly superior and much more suitable for consumers.

My InergyFlex is arriving today after a 3-month wait. Woo- hoo!

For me, the peak and constant output is the most important.

Love the transparency

Thank you for explaining it in a way that I can understand.

I'd like a unit where I can replace the battery when exhausted. I need pure sine wave but willing to do without inductive chargers and other small conveniences.

I love the intro 😂

I got a good laugh out of that, Kris. Still walking around the house chuckling. “Remote cabin” “Off-grid cabin” “Monitor over the Internet” Tears in my eyes laughing. 😂😂😂

Great review thank you. I decided to get this over other options including Delta 2 max and other technically better options. My logic was I have 1+some solar panels for short backup emergency power and camping (including powering the ecoflow wave portable AC), and for the price I can eventually get another Delta 2 and its still less than the max, that way in a longer term emergency one can be solar charging and one can be backup power and hopefully can just keep swapping them indefinitely. :)

I just bought 2 for $650 each on Amazon :) Gonna connect them in series. That way I have 1 if 1 fails in my campervan.

My Ecoflow Delta 2 unit is about two months old & currently won’t charge beyond 23%, had been planning to buy another but now I’m not so sure. Don’t think it’ll last much longer myself

Thank your for condensing all of this research. Gonna check the Bluetti one out to. Thank you!

Solid work as always Kris.

Thank you for doing all the work on these!

Your comparison spreadsheet is great but you need to add a link to your KZfaq channel in it. I opened the sheet, closed KZfaq then had a tough time finding the video I got it from.

Really appreciate you making this video

After seeing how ecoflow’s customer service treated RoseRedHomestead I think I will pass on any Ecoflow product because of their poor customer service and trying to bribe them to change their Amazon review. Considering the other options you have reviewed.

I can definitely understand why it would be good to have something like this. But I just cannot justify it. I have a small solar powered battery pack that will charge my phone and that's about it. if I could afford it I would be all over one of these type of generators but I just can't do it.

Not saying don’t buy one but be aware if you have any issues with these you will be without for several weeks and if out of warranty they will not supply parts so you can fix your self or service manuals so be prepared to own a expensive brick in the future not something you want to rely on in an emergency situation

This is useful I'm still researching what I need, but I'm in SoCal and a downed tree took my power out for 60 hours so I'm looking at solar generators since I'm in a place with earthquakes and can't rely on gas or propane in this environment, but also my place is 850 Sq FT so really considering my energy needs here. I think for my the ecoflow would be generally fine since it's not likely to see heavy use, but we will see.

Hi all, So....I have a hack that I literally just thought of for people who can't afford another Delta Pro or extra battery BUT need additional power and own another ecoflow battery. I have called ecoflow and given them the idea as well and they confirmed that it will in fact work!! I then asked them why they don't tell everyone after I've told them and they said they would "escalate the idea" to their top tier and perhaps add it to their FAQs. So here's the idea: We've been told that you must have like systems in order to use them together. This is NOT actually true. If your Delta Pro is low on power (or any other ecoflow system you have) you can simply plug its charging cable (in the rear) into the front of the secondary system. In other words you're using the second system as a wall outlet of sorts. This works especially well in the evening when the sun is down and there is no more backup energy. What do you do when the sun is up?...even better...plus the second system from the rear into the front of the Delta Pro. This allows the sun to charge them BOTH regardless of the differences of their capacities or sizes!!! The only word of caution they gave me after saying what a great idea this was, was to say don't forget to lower the charging speed on the Delta Pro once it's plugged into the front of the second system. Guys this means you can use anything from a River and up to charge your Delta Pro OR any other ecoflow system. If this works for you please like my comment and say "Thanks T!!" just so I'll know at least I was able to communicate something helpful to the solar community-especially since these systems are sooooo expensive!!

I just bought one

Just picked up one of these and their 220w solar panels for $999 on Amazon Prime day sale. Not exactly sure how I’m going to use it. Im hoping it can lessen my carbon footprint. Maybe lower my bill but I’m mostly wanting it to power necessities if the power goes out. Last time I lost power for about a full 24 hrs and it SUCKED!!!

Thanks for the informative video. Rare to see these detailed comparisons. If possible please compare the delta pro with zendure superbase v and the new anker powerhouse 767

Love the “probably Abraham Lincoln” quote! 😂😂😂😂❤😂😂😂😂

Good review. It would be good to know what the "charging" kilowatt efficiency was too from dead to full (after all balancing etc.). Regarding the poor AC output efficiency, I suspect you'll find that they are being VERY conservative on the "discharged" (and/or possibly the fully charged) state voltage on these to get better life cycles. What that effectively means is they are cheating the 1024Wh capacity and trading effective capacity for cycles. No way their inverter is that inefficient from the tear downs I've seen (they are great, well designed electronics). Not a bad thing, but they should "derate" their advertised kWh, then, if they are going to use "conservative" charge/discharge levels for the batteries. I also suspect you could measure the "80% charged Wh" value from measuring with your kilowatt device, times a 80-85% charger efficiency number and get a better estimate of what they are getting for their final "utilized" capacity (since the slow charge last 20% is largely much more inefficient and used for balance charging and stuff).

Good review, thank you!

Excellent and VERY detailed review on a "solar generator" I'm thinking of buying. With the Delta 2 AND an Off Grid TREK 220 watt solar blanket I can re-charge my E-mountain bike's 2 Li-ion batteries (via a patented single charge port). The TEK unit will be draped over my CX-5 windshield and roof and locked thru the grommets. The power cord is routed into my trunk to the charger. When I return to camp from hunting I just plug my bike'd charger unit into the Delta 2 and VOILE'! A full charge in less than 3 hours. I like that I can buy a companion ECO FLOW additional battery and the Delta 2 for about as much total cost as a more powerful BLUETTI AC 200 Max for close to the same money but have more versatility.

I don’t know if I’m not typing in your discount code in right but it’s not wrong

You should check out Grid Point Designs. They were at the RV and Van Expo in Portland Oregon last weekend, and Ecoflow decided to not even show up! It's a much higher grade product.

I’m looking for a solar generator that I could use in place of a gas generator strictly for power outages. This means the unit is going to sit for long periods of time without being used because I really have no need for it other than for when the power goes out in the home. I contacted EcoFlow and it seems that the delta2 is really not designed to be stored for long periods of time with a charge so it doesn’t look like it would be a good choice for emergency back up power. I looked at the information for the Jackery 1000 pro and the documentation says that you can store a charge of up to 80% for 365 days. So it seems like the Jackery 1000 pro is a better choice to be used strictly as an emergency generator for when the power goes out. Have you looked into this yourself and have come to any conclusions? Thank you so much for your help.

When you scoped it and saw the distortion, I assume that the load was mostly resistive to eliminate any reactive load influence on the waveform? AFAIK, when measuring THD, that i expect would provide the most accurate and repeatable measurement.

Why doesn't ecoflow customer support offer support? They promised a call back but forgot me.

The Delta 2 is geared to work with the second battery once you hooked that up your efficiency comes way up.

I left my Ecoflow switched off in my van for about a week and it lost about 70% off the battery life from a full charge, is this right? It had and extension lead plugged into it but was all powered down, I was surprised to turn it on today and only see 25% power left after leaving it for a week

13:38 Not sure what Jackery model is behind you but the comparable Delta2 model is the Jackery 1000 and it only accepts 126W(12~30V,7.5~8.33A ) solar max input. Even the much more expensive 1500 max input rating is 400w according to the user manual.

It'll power my 6qt insta pot, therefore I WILL SURVIVE! 🍳☕🤠😁👍

Efficiency is largely dependent on rate of discharge. I've seen a pretty wide range of numbers on this unit. As long as you're consistent with your testing methods, your numbers should be sound. Not suggesting you do, but just don't attempt to discharge one unit in an hour and another over several hours. I've seen several others neglect this fact. My Bluetti has a much different efficiency if discharged over several hours since it's using 60watts per hour just keeping it powered.

I thought this was the one until the comment section hit me with the "HOLD UPPP!"

I find that recharging my solar generators with a gas generator is much more reliable and effective than solar panels. The EF2 with the super fast charging makes this by far the best recharging setup. I just put in just enough gas to power the generator for a short time which fully charged two or 3 solar generators and I am set for days. The solar panels are nice as free power source but are unreliable. They don't work well when it's storming or cloudy outside and do not work at all at night. I would recommend a smaller gas generator before the solar panels as most gas generators are about the same as the solar panels. But do get some solar panels as they will still add in some power to your system. Thanks again for your time with putting together these reviews as many of us would be stuck with a lot of junk. 😎🤠🔥🔦🍳🍮👍

I dont need more then 500w. I bought it with their own solarpanels, Was expensive, But more effective then normal sun panels i read. Also its just run in outide the window like a carpet. Very easy. I bought a 220w ecoflow sun panel. I might buy a normal 120w aswell

Almost all of the power stations in the same power category don't have an option to connect to an extra battery, but the Delta 2 has.

Thank you for the information.....it does help!

Don’t suppose the efficiency improved with firmware updates?

I’d love one of these for my setup thx for sharing.

I am looking for an EcoFlow battery to be an energy backup for a sump pump. How should I hook it up ? Ecoflow to the outlet and then plug the sump pump into the EcoFlow ? ...

Which solar generator would you recommend for apartment use in winter for a canadian if our grid were to go down? Say for Lights/wifi/portable heaters being the biggest thing in winter/fridge/freezer/washer type things to just look at.

Interesting, thank you Chris God bless 🙏.

Completely new to this. Just ordered a delta 2. Do you have a video on hooking up solar panels that are coming with it. Intimidated about hooking up the panels. Deer in the headlight.

Chris please let one of those reviews be on the BLUETTI ep500 pro generator ❤

The best thing about the Delta 2 is that I can max out the capacity to 3kWh. No other power station can do the same.

Guys, I need some help. I can’t choose between delta 2 and max. Everything on the max seem perfect but delta 2 is a lot lighter, like 10kg lighter and I’m a woman without a car. The battery can run more cycles. I think it’s around 3500vs 800, I can’t remember the exact. And it is a lot cheaper. But the efficiency are poor and max has a much better solar input, large battery. Thx.

Pity about appalling customer service from both overseas PR and EU website. PayPal dispute filed

What would be the best choice for emergency use during blackouts. Or maybe what features should you look for? This would be for a senior with some minor disability issues.

OMG. I’m not getting this thing. NEVER SAW SUCH AN HONEST REVIEW.
