JUST LAUNCHED a NEWER version of this video we did with Much more detail and helpful info, link is below
th-cam.com/video/Oo-b58Zngxw/w-d-xo.html
I have this model Delta 1300, and I found your video on using the fridge just what I needed to help me decide to get it for this reason, but my problem I've noticed since it has no 3 prong on Delta 1300, I'm finding it hard to get the right heavy duty extension cord long enough about 40 or 50ft with a 2 to 3 prong like you used, and also My fridge has 3 prong, it uses 572kwh yearly, GE 120vac, 60hz, 1.50amps, model GDE21ESKGRSS. I see you used adapter on your fridge as well. Where did you get your green extension cable 2 to 3 prong and adapter? This is all I need but with correct power amps and voltage not to do damage to Delta. Can you help me please. Also Brooklyn is a joy to watch. Thanks for all your helpful info.
This is our newer video I’m not sure if you had a chance to watch it it might help answer some of your questions
Thanks for watching our video and especially your note on Brooklyn

Thank you for doing this test. I own a Delta as well and I've been trying to mentally run these numbers in my head. We need more of these real world demos on TH-cam. So many "influencers" will get a free unit and they either go the route of pulling out a bunch of meters and scopes like they're some kind of physics lab professor or they plug it into something like a microwave to demonstrate that a machine will "cook" a hotdog. I appreciate TH-camrs like you that go the effort to show what a machine so capable of in practical real life scenarios.
CH Thanks so much, that was my goal and honestly I wanted to see for myself. More Sun would have made this unit last longer but it was fun.
Is it not true that there by putting the solar array in parallel you limited the max input to 200 W? If the max input for the delta is 400 and there is going to be a drop in efficiency, I would say that the problem is not the clouds so much as not maximising the huge potential of the EF delta to recharge in just 3-4 hours at 400w. That way, when your light disappears the unit will be fully or close to fully charged and there will surely be sufficient battery to make it through the night. I wonder also about using extra long cable on the refrigerator end. Once you have your delta in the house, you could probably improve slightly by plugging the fridge directly into the power of the delta. I'm just learning this stuff so I would be happy to hear if my thinking is correct.
@@VistasdelMar2008 Two 200W panels in series has the same power as two 200W panels in parallel. In series the Voltage are added up but the current stays the same, in parallel the Voltage stays the same but the current added up, in either case the power is still the same.
I.E. two 12V 1A batteries in series, the Voltage will be 24V, so 24V x 1A = 24Watts of available power.
Two 12V 1A batteries in parallel, the Voltage will be 12V, so 12V x 2A = 24Watts of available power.
@@VistasdelMar2008 Yes shorter wires are better, but the loses are lower on higher voltages and with a fridge drawing around 40 watts the loses are negligible and probably not measurable, so it's always better to have a longer AC cable and shorter DC cable (which is a much lower voltage and will cause loses more easily).
It's all about watts. I suspect the fridge should be cycling on and off and isn't always drawing 40 watts, although many modern fridges have auto defrost using a heater, so can suddenly start drawing a couple of hundred watts when they start a defrost cycle. So lets assume for ease the fridge averages 40 watts an hour. So in 24 hours it consumes 960 watts, this means the solar panels need to feed back in 960 watt in order to restore the battery to a full charge, well a bit more as their are losses in charging a battery, so call it 1000 watts. If you had a big solar array that could output 1000 watts an hour and the sun is out, it would only take an hour to restore the battery charge, if the solar array is only 500 watts an hour, it would take two hours, if 250 watts it would take 4 hours, if 125 watt it would take 8 hours, but over 8 hours there will not be many days that are continually bright enough to mean the panels are outputting their full rating for 8 hours straight to achieve 1000 watts in total. In this example, more watts are consumed than are generated by the panels so the battery is depleted. You need to over spec a solar array quite a bit in order to ensure you make the most of any limited sunshine.
I did the same test but without panels. The Delta Pro gave me 25 hours attached to a refrigerator (old one). I will test with 450 watts when I get better. (Hsd a stroke last week).
I got my Delta unit last year when they had just arrived to Puerto Rico and almost no companies in the island had it except for one. Last year I wouldn’t even dream of finding a YT video with a demo to this level of detail. A million thank yous from Puerto Rico 🇵🇷. Best thing is that I did a similar test with mine just recently, only for a shorter period of time, and I was able to compare my results with yours. Here in our island we have the benefit of getting full and strong sunny days. My Delta unit was getting little over 200W of input at some point. My fridge is from around 2003-2004 and was using around 160-170W in average. I had it hooked to 3 100W flexible solar panels connected in series with an extension MPPT cables outside laying flat on the floor. Numbers looked pretty similar to your test considering there was full sun going outside. I had my unit inside during the test. Again, thank you so much and I look forward to watching the updated video you mentioned above. Blessings 🇵🇷
Finally a video where I can have a clear real life use case.
One can estimate roughly what you need to get for a single load like this.
Thank you
You can have your refrigerator cold and unplug for a couple of hours to allow generator to gain more charge then plug refrigerator back in. By doing it this way your food does not spoil and you can keep your Delta charged and running for days.
Absolutely I thought the same thing get one of those timers and put it on so the refrigerator shuts off for an hour comes back on for an hour give the sun time to charge the battery back up think that would work I wish you would give that a try they sell those little timers at the hardware store where you just plug the extension cord in and then plug your refrigerator and you can set the timer to come on and off pretty simple I've got a whole box of them maybe I'll give that a try it's like you said it'll stay cold for a while if you're not digging in it all the time LOL
Absolutely , and also I couldn’t understand is why the refrigerator was drawing power at night but zero during the day?
@@flappingarms9335 Automatic defrost cycle uses heating elements. All frost free refrigerators have them. I'm old enough to remember my mother having to manually defrost the fridge.
As a suggestion: in a power down, make sure your freezers have an external readable thermometer. Turn OFF your freezers and periodically WATCH your temp. When NEEDED feed them som juice from your battery bank, once right temp reached, off it goes. Most fridges and freezers HOLD their cool if left closed.
Freezers have a thermostat to do that for you.
There are things you can do to make the fridge use much less power: Turn off the self-defrost and anti-condensation heaters if your model has that feature. Set the freezer to 20-25F. Set the fridge to 40-42F. Don't be tempted to open the door unnecessarily, not even for a quick peek. Also, solar panels are sensitive to shadows when run in series because the 1 in full sun can't produce more power than the 1 in shadow. Nice video, thanks!
Thanks Bob
What does it mean one in the sun can't produce more than one in shade?
@@pinkpunkpunk3099 On panels wired in series, a panel in the sun is limited (roughly) to the output of the panel in the shade.
@@Bob_Adkins So if I understand the least effective positioned panell in a series will hold the group back? Sorry I am a newbie
@@pinkpunkpunk3099 Correct! You've got it!
Thanks for making the video! I know it was a lot of work.
The only big problem I see is that you shouldn't connect the solar panels the way you have it.
From the voltage output of each panel you mention, all 3 of the solar panels are for a 12v system, putting out about 21v to 22v.
By connecting the 2 100w panels in series, you've created a 24v system, or 44v give or take a few volts. Then you connected a 24v system in parallel with a 12v system (the 200w panel). So your are connecting 44v and 22v in parallel a definite problem. The 22v 200w panel will drag down the 44v voltage array to 12v.
The only way to connect these the way you have it, is to use a 24v 200w panel (44v output) that puts out the same voltage as the 100w array. Then you'd be golden and get the full power/wattage out. Another way would be to use 2 separate charge controllers, 1 for the 200w and one for the 100w array and feed them to the battery bank. However, using the all in one power station this isn't possible.
Like another poster mentioned you are better off using just 200W total. If I were in this situation I'd definitely buy another 12v 200w panel and put in parallel with the one you have for the power box/generator, and buy a charge controller and 100ah LifePO4 battery for a separate system to use with the 2 x 100w panels in parallel to use for another purpose in the house.
This is what I'm doing for my solar ham radio shack and emergency power, my video of it is on my channel.
Yes this is very important, if the battery input can handle 36V then you would want all panels in series. (important to check if the smaller panels can handle the current expected)
Or else all 3 panels in parallel if the battery handles 12v
12V in parallel with 24V is completely turning off one parallel legs... triggering reverse protection in the panels probably, damaging them if you are unlucky
This is the very video I've been searching for for a long time. I've wanted a setup for the very same function. Power outages are common on the West Coast. Thank you! Excellent vid!
Thank you check out our new video when you have time and has a lot more detail th-cam.com/video/Oo-b58Zngxw/w-d-xo.html
I've been considering the purchase of one of these units for a while now... Thank you for the excellent evaluation!
Thanks Mark thanks for watching
Hace meses o años buscando una explicación como esta. Al fin encontré el vídeo con la información que yo quería saber. La nevera es totalmente vital para conservar nuestros alimentos y algunos medicamentos en buen estado. En mi caso uso un respirador para dormir, por lo que busco la manera de que me funcionen las dos cosas simultaneas. Hiciste el mejor vídeo que he visto sobre el tema. La demás solo enchufan diferentes cosas y nada mas. Gracias fue de total ayuda. Desde Puerto Rico. 5-21-2022
Great video! I have been wanting to see real world applications for these. I have an off grid cabin and am trying to decide which model to use. Thanks and you gained a new subscriber!
It all depends on what you're looking to do let me know and maybe I can help there are other models I'm very familiar with
Great real-world test! I'm going to make some calculations. Rule of thumb for solar is the maximum you get x 6. So, roughly 180W x 6 = 1080 Wh/day. Your fridge is 478kWh/year which is 1309 Wh/day. Unfortunately, though, there is inverter overhead from the power station. The overhead is approximately 10W continuous plus 15% loss of efficiency (for most inverters). So this winds up being 240Wh/day in overhead plus 1309*0.15 = roughly 200Wh/day with an 85% efficient inverter.
So the calculated difference is: 1309 + 240 + 200 = 1749Wh/day in consumption verses 1080Wh/day received from the solar. You are losing 669Wh of capacity each day. The EcoFlow Delta (non-pro) has 1260Wh of batteries. It should last.1.9 days, approximately.
And that calculation is very close to what you actually got, taking the clouds into account. You got roughly 38 hours. With two days of full sun you should have gotten roughly 47 hours. But would you have? I think so, yah.
Thumbs up!

Show off
I am only beginning my research, so I'm no expert. But are you sure about that rule of thumb? If I understand correctly, that number varies highly by geographic location and time of year. For example, I live in a northern state. In the summer we get 16 hours of daylight and 55% of days are "mostly clear" or better. But in the winter, we only get 10 hours of daylight and only 20% of days are "mostly clear" or better. That's a lot of difference even in the same location. In addition, surely Southern California will get a lot more wattage out of the same system than Maine. If I understand correctly, for my region in winter, I'm looking at well under a factor of 3. Which is pretty depressing. Do you have a source that might give me more hope for your factor of 6?
@@annnonomys3132 Yes, is true, but don't the cooler winter temperatures increase the efficiency of the panels? This would offset the fewer hours of sunlight during those months
You’d get more hours by turning the fridge off and on through the day. They hold the cold quite well you’d probably get an additional 12+ hours more.
Good idea
Thank you for a real world test - not just specs from an expert! Good test: the takeaway is to get a big enough solar generator with reserve for poor sun days.
Or get batteries, inverter and huge panels for sale price as portable generator price and last longer
Awesome test. Best combo I found was a few solar panels a few Deltas/River Pros and an Alp propane generator to top off if the sun isn’t out. Very inexpensive overall combo. Can run most of a house for around $3k.
Thank you Robert and thank you for watching stay in touch

Bless you my son for this video!🙏
Thanks same to you
This is a pretty good video of an actual longevity test with the Delta 1300.
Hi thank you
Great real world test. I've been thinking of getting this unit but didn't know how practical it would be to power a refrigerator. I will say you stopped too soon. Your refrigerator should be able to stay cold long enough for the sun to come back out in the morning to recharge the battery. So I think in practical terms you could in an emergency go much longer. Thanks for your test.
I like this test as well. However my fridge doesn’t use 45 watts. I should probably get one. I’m FTOG on solar. And my house fridge maxes out ~8 Amps. I can go maybe 10-12 hrs on a ~2400W or 12v\200AH (2x100ah =P) however the mppt is 40amp max for now. I’m probably not getting full daily charges. But connecting to the bus bar at the inverter let 5 times power through as opposed to being direct to batter bank. This move cut the nightly 4 hour generated charge, down to every 3-4 nights (cloud dependent) for only 1-2 hrs. Looks like it’s keeping up during sunlight hours instead of falling behind.
Mark check out our new video, we tried improving it and added more detail th-cam.com/video/Oo-b58Zngxw/w-d-xo.html
Brilliant test for normal real world use. This is what most people who aren't solar geeks would do and shows the casual user what they could get from one of these. I'm currently designing a similar setup for my house to run base load for 24hrs including fridge freezer. I think a minimum of 600w of panels gives you a really good chance of a week especially in patchy sun environments to cram those electrons in to that battery! Fantastic real world review, well done.
Thanks Barry appreciate that, I’m working on more to show a few more examples
Thank you for running this test!
Thanks so much, thanks for watching
This kind of test are really appropriated,thank you and keep it up
Thank you Kyle
I would have turned the temp of the fridge up to something which is still safe but not optimum to reduce the run time of the fridge. Also, adding some ballast to the freezer and fridge in the form of water jugs would also help hold the interior temps longer and reduce the run time. It would also have been wise to keep your unit fully charged and not cripple the test by 10% right off the bat.
All that adjustment means open door time. The fridge and freezer should be fine for four hours if left unopened depending upon the temperature in the room. Then plug in the Delta Pro generator.
I want to say thank you for doing this test I've been looking into different options for my grandmother's house in Puerto Rico they lose power quite a bit I'm looking for a system that will be easy enough and hassle free for an 80 year old two maintain I really like your video Thank you I hope to see more content from you
Thank you and say hi to grandma, Puerto Rico is beautiful and solar will definitely help especially with the storms they had, always good to be ready and prepared.
Thanks for the video. Made me more happy with my purchase of the Delta.
Hi Ronald thank you
Got exactly the information I need to decide if this product is for me. The refrigerator is a fine illustration: I have lost so much merchandise stored in my freezer to power outages that I can practically pay for this model!!!! Thank you for your endeavor and this video. 👍
Jeffrey thank you so much I hope you stay with us
Great test. I have both a Delta and Delta Max. This test gives me an idea of what to expect if I have to use either of mine. I live in Michigan, so our weather is similar to yours as far as using the solar panels. When I bought the Delta, I went with the package that included two 160w panels. Did the same deal with the Delta Max, but got four 160w solar panels. Back in October, I tried out the solar panels on the Delta. Set them up mid-afternoon and ran them for about 2 hours while the sun was still high. Was drawing about 110w from the sun. The Delta already had about 93% charge in it and in those two hours, it moved up to 95%. After that, the sun was going down and the incoming watts dropped to about 5%, so then I took it down.
Thanks James yeah, the delta max 2016wh unit would be a step up and then the delta pro also but definitely a fun test to do, thanks for your comments and thanks for watching
Please can something gift me with this solar gen...it total black out here in my country ,,I don't mind if I can pay some little with some support I need it
It wont do u much good unless u got big solar panels and know how to use this stuff.
If not, it will just run down and be useless
Very informative video and thank you for taking the time in doing this experiment. I just purchased my Bluetti AC300 / B300 with a few 350W solar panels. Looking forward to playing around with it.
Here is California with wild fires the electricity ⚡️ goes out which is annoying. I figure a platform like the EcoFlow Delta Pro would last you about a good week under your specific conditions. As you mentioned the suns 🌞 strength is important along with panel efficiency.
Thanks Sergio, The pro can handle up to 1600w of solar panels and you can add 2 additional batteries
thanks man! that was such a amazing help to understand the way how it works from a simple way!
Thanks Brian, scroll up to the top of the comment section when you have time. I posted a newer review with a little bit more detail that might be helpful also.
Thank you very much for doing this test, without sponsorship..!
By the way: Your pronunciation is crystal clear and therefore very well to understand for a not-native speaker as I am. In many cases, American people have a strong accent, which makes it more hard for "others" to understand everything - but you pronounce so nice and clear that, after some seconds, I somehow 'forgot' that I am not listening to my native language. Thank you once again !
Thank you
I have been using a Delta with my Dometic CFX3 for about a month now. I'm very happy with how long the Delta powers it.
Same here I’m impressed
that was awesome!!!! & Thank u 4 putting yr dog in the video... He really thought that u were talk'en to him!!!!!!!!! Great doggy!
More Sun was not the only way you could have done better. If you had more Solar panels, you would have had more AMPS, and your battery would have charged up FASTER with the amount of Sun 'available'. Still, you helped a lot of people to see the advantage over paying for gasoline.
Bruh. P=V*A. More amps equals more Watts. 🤦♂️
Thank you for your video on this! Reaffirms my thoughts on two is one and one is none
Exactly what I needed to see! Thanks!!!
Thank you
Very good video - shame you had to cut your door ledge for the cable but that shows your commitment to the test. Clearly a larger unit like the 2016wh delta max will add at least another day to the time or the 3600wh Delta Pro will almost treble the time. Very useful thank you
Thank you so much I appreciate your feedback
If he had the max ran double the solar panels I think this test would have gone on for sometime. If you had the panels you could run 2 400 watt solar panels and that would have kept it going to weeks if not months I'd think. Hope he does more tests like this. That fridge really sucks up the juice with a battery of 1200ish kWh isn't going to last nearly as long as that 2000 kWh you were suggesting.
That's really impressive for the Delta 1300. Running the fridge for almost 38 hours.
Thanks I agree
If I had more Sun it would go even longer
A Delta 1300 provides 1300 watts, the fridge seems to consume around 40 watts continually, so 1300/40=32.5 hours from a full battery. The extra few hours has been provided by the solar panels, so it's all in spec, not that impressive really, just what they advertise. The solar panels haven't really made too much difference overall.
@@chrislee6650 You're ignoring the self consumption of the Delta itself. It probably uses around half as much as the fridge does on average by itself.
Great demo, Tech Made Easy! Thanks for sharing this
Hi Gaia thank you
Thank you for the video. I needed the information as I have the Delta 2, the Delta Pro and the River and want to used them to power my Fridge, TV, Internet and Kitchen appliances during a power outage.

I have the Delta Pro with an extra battery, gives me 7.2KW of power, hooked up to 1600 watts of solar. It was expensive, but dam near powers my whole house when needed.
Wow you got the Beast in amazing setup and it will last for years because of that lithium phosphate
Where did you get that deal? Sounds better than Bluetti AC300 x 2 B300 and 3 PV200 panels
@@EgbertOostburg Costco has a good price on the Delta pro
I got my Delta 1300 primarily to run the fridge through the night. We have a wood stove, a deep well and an oil fired boiler for heat and hot water. We run a gas generator intermittently during the day to top off the 85 gallon water tank, warm up the rest of the house and get some hot water for showers, cleaning dishes and mostly to cool down the refrigerator. We don’t run the gen at night out of respect for the neighbors so that’s a long time that the fridge is powerless. Now we run the fridge all night no problem and top off the Delta with the gen during the day. It’s a game changer for us. P.S. my fridge is 33 years old and pulls around 400 watts and the Delta will run it for about 8 hours. We’ll be upgrading that soon. Great video!
Thank you so much for sharing that, I'm glad you found the video helpful. We also did a test on the new delta max with the extra battery without solar, if you'd like to see it here is our link, sure hope you subscribe and stay with us

@@thaddeustroyer We’ll be updating our fridge this Wednesday with a new, slightly smaller LG model. I sure hate to see my old reliable fridge go but it’s looking kinda beat up and since the kids have moved on we could do with a smaller one. I’ll be running it off the Delta some time soon to see how it does and I’ll let you know the result.
@@slowpoke1315 that would be great, I like you, hate to see the older, still useful stuff go away but efficiency is something to be considered. Thanks for the update and I also will update if we decide to upgrade ours or at the least let yall know what our watt usage and runtime is for the old thing.
Appreciate your effort and guidance on this!!
Thank you Oscar
Thanks so much..I'm looking forward to seeing the results on Delta pro
Great real world test. I looked at the specs and the Delta has fast A/C charge. About a half hour hooked up to a cheap 1kw gasoline generator Monday evening would've easily gotten you through to the next day and, hopefully, some sunshine.
Thanks it was fun, redid the video with more detail , if you have time check this one out let me know what you think
th-cam.com/video/Oo-b58Zngxw/w-d-xo.html
Thanks for posting. Echoing what a lot of people have already pointed out regarding your panels. 400 watts of panels should have been bringing in way more than ~180 at best. I'd be really interested in seeing a part two if you'd apply the tweaks mentioned regarding the solar panels. It'd be an interesting demonstration of the difference small variables can make. i.e. losing power after 40 hours vs. going indefinitely.
Thanks Henry I’m working on a few for sure, just got my hands on a 400w panel.
@@TechMadeEzy I think the main point Henry and others are making is how, not what. Most folks don't have an endless supply of panels, and when the watts go above 200, these things get crazy expensive. Trying focus on doing more with less would augment your already fantastic review. Cheers from sunny San Diego
@@cwr8618 agreed. I think if he would have wired the panels differently it would have gone much better even with clouds.
@@Mike-. i should add - i have the delta max. After like 80% or 90$ charge, the delta automatically slow charges the final 10-20% of the charge for longevity. I have 4 160W panels wired in series, and i typically get about 450W input by 10 AM.
Sounds great and im sure your 4 panels match, right(?
Yrs ago 1 of the 1st things ive heard is to not mix and match panels lol
I liked AND subscribed! Thank you for this info🙏🏼💕
Thank you and please see our new version of the video. Definitely some improvements.

So I live on a 38 foot cruising sailboat currently anchored out in Mazatlan, MX. The water temperature is 88 degrees, air temp is ~90 degrees F. 400A of battery, 400w solar, 6 cubic ft. Frig./freezer with radiant barrier, gapped, and 6 inches blue foam all round. Bottom and hull side is 7 inches. The fridge system has a water cooled thruhull condenser.
It uses about 18-22amphrs a day. I can go around 10-14 days without sun. All lighting is LED. Batteries are charged by 10:30am in the morning usually. I built the fridge and systems myself. Probably helped I went to school for aerospace and physics and really loved heat transfer and thermal dynamics.. Good luck with your system. Glad to see somebody inspired to improve refrigeration power economics. The A/C is next. Batteries are Firefly’s
Check this comparison out, it might help Andy

@@TechMadeEzy taking this down to basics. You are applying energy to remove heat that is leaking into the refrigerator. Get a better refrigerator? The hardest part is we have gotten so used to front loading frigs. and they introduce a lot of heat when you open them. The second tough piece is manufacturers have become complacent in their insulating practices. It would be interesting to do the ice block test on your frig.
Put a block of ice in (as large as will fit), let it sit for at least 2 hours, (to cool the box off) then weigh it. Close everything up for, say, 12 hours, and then weigh it again.
Calculation #1 (Heat loss rate): ((Lbs of ice melted) * 144)/hours= BTU's per hour
Calculation #2 (Heat flux): (BTU/hour)/(Square feet of ice box internal surface area)= (BTU/hr/ft^2)
Calculation #3 (Temp difference) : DeltaT = Average external temperature(DegF) - 32
Calculation #4: R = DeltaT/(BTU/hr/ft^2)
This give R in [°F·ft2·hr/BTU] The higher, the better. A good minimum number for a fridge would be 15, for a freezer 20, but many people live with numbers less than this. Very roughly, doubling the R-value with half your power usage.
To convert to the metric equivalent R value, [°C·m2/W] divide by 5.68
Good real world test! If you put the two 100w panels in parallel and series them with the 200w panel, you'll get more power.
Thank you yes could have done better with panels 🙏🏻
You’ll get more voltage; no extra wattage
@@johnsmith-pr3ll That unit has a 10amp max input right now which he is maxing out in the video. He'd definitely get more wattage using a series connection.
Yes. I thought I was the only one who noticed. The voltage of the smaller panels connected in series would drop by 50% when connected in parallel to the larger panel with 50% less voltage. Assuming unit support 42v
Thank you, thank you for doing this video. I have been contemplating getting an EcoFlow Delta, but wasn't sure how long it would power my refrigerator, freezer and a few other things during a blackout. I actually have the exact same refrigerator as you, so that was an extra bonus. Thankfully I already have a 6,500 watt tri fuel generator hooked up to my natural gas utility with backup propane stored on my property, so cloudy days would not pose as much of a problem for me. The addition of the EcoFlow Delta to my generator solution would allow me to only run my generator a few hours a day so I don't piss of my neighbors as much. LOL. Also although I want to get solar panels eventually, I could delay getting solar panels until I have the money, but still have a workable power out solution.
It’s nice being ready, have you checked out the delta max and delta pro?
@@TechMadeEzy Actually since I made that comment, I purchased the EcoFlow Delta Max 2016 watt, should be here in a couple weeks. Amazon had a $200 off coupon, one of the rare times procrastination worked in my favor. LOL.
Hope you used our link 🤞🏻
As for noise from a generator you can put it in a hole in the ground, barring water accumulation. Or plywood or sand bags around it to cut down on the DBs. Stay stealthy my friends.
Really enjoyed this!
Thank you
Thank you so much for making this video!
Thank you Mark
After watching the video I am now really inclined to get the Delta 1300. It's really powerful.
Yes it’s nice thanks
It isn't really powerful, it's pretty bog standard. It is using a typical 100Amp/hour 12volt battery configuration, the voltage tends to average something like 12.8 volts (Lithium iron phosphate perhaps, not sure), so to get the wattage it is 12.8 x 100 amps = 1280 watts an hour, they round it up to 1300 watts.
I just got my EF Delta Max omg yess I'm charging it up fully today and will see how does on my winter and also my RV too
Congrats it's an amazing unit thanks for watching also happy holidays
Just trying see how going to wire it with out it being in a loop
Yes ery amazing unit next best thing to the Titian
Congrats my delta max just arrived too. Very excited to have
You are going to love it it's almost double the capacity
Thank you for doing this video!! Normaly you never see a real time test, all of them are aproximations.
Thank you
First, I love your lab! Second, awesome test, thanks for doing this.
Thank you for watching and thanks for your feedback
If I'm ever in an extended grid down scenario I plan on using a 24 hour outlet timer to control when the fridge comes on/off. I've read that a fridge can stay cold for about 4 hours so I was thinking of programming it to run for an hour and having it off 4, then repeat. I have a battery operated wireless fridge thermometer in the fridge and freezer to keep tabs on the temperature
This is a great idea thanks CH
Great idea👍👏
Perhaps looking into a thermometer that has low temps to put in the fridge. And might want to get spun up on food safety if you're testing those waters. Your health is important.
Your smart to lengthen the 'off' periods with minimal door openings. The contents temperature rise is minimal compared to air temp rise AND one long compressor run cycle is much more efficient than several short ones.
A fridge will stay cold, but it is still warming up during that 4 hours it is off so will need to run longer and harder for the 4 hours it is back on that it would do otherwise being left on continually. This could give rise to the situation that in 4 hours the freezer is off it has risen higher in temperature than the compressor can reduced it again during the 4 hours it is back on, and your freezer is still defrosting, just slowly. Depends on your aim, are you wanting to preserve frozen food at -18c during a power outage, or happy to let the food start spoiling (as it will at ever increasing temperatures even if still below 0 degrees), but just stop it creating a puddle of water?
Thanks for this test! I think these power stations are fantastic and I own several EcoFlow Delta and River products. I am waiting for my EcoFlow Pros to be shipped. I think these products work just as well as gas generators without all the fumes and expense from having to purchase gas.
Hi Eve thank you for watching, I hope you stay with us on the channel happy holidays
excellent video, it helped me very much to understand how these units work. I just bought the delta Pro! again thank you.
Pro is a great machine thanks Toby
Thanks for doing this practical test. The main consideration for getting this inverter is keeping a freezer or something up if the grid goes bye-bye
Thanks also if you have time check out our newer more detailed review
th-cam.com/video/Oo-b58Zngxw/w-d-xo.html
Interesting test, just got an Ecoflow, for emergency use. Lots of good info in the comments, but no one mentioned the mains cable coiled on the drum, doing this causes loss of current, so you should always unreel the cable to get less drain.
Explain why please
@@noahvillalpando hi noah, as I understand it, coiled cable acts in such a way as to use/ lose current that a uncoiled cable does not. Which is why cable extension drums always say to unwind fully if using high demand items this is to prevent them overheating, blowing the cb and/or melting the insulation leading to fire.
@@foamyflightmaster9385 loosing electricity from coiled wire doesn't make much sense to me but I'm no engineer.
Loosing electricity due to heat makes more sense. Since the wires coiled up it'll build up heat that should have been able to dissipate into the air.
Hell loosing power because he's running it through a spool of wire instead of just a single cable makes sense too.
Idk when I read your comment I thought you were saying for example that electricity is a fluid and somehow unspooling would stop it from pinching the line 😅
@@noahvillalpando - when electricity passes through/over a wire it creates a magnetic field around the wire. A wire in close proximity will react to that field (inductance) and generate electricity! A coil of wire with power passing through it will create a 'choke' effect (resistance) as the coil's combined fields are acting against each other creating a stronger magnet. So stretching the coil of wire out eliminates the 'choke' effect . . . . but it is still a long wire which has resistance naturally. Hope this helps . . .
@@richardhobbs7107 thanks for that....so you get hit twice...magnetic field, and resistance from long wire, right?
Man, i really undersold my shot lol, i had a Measley 5 hours, but i was clearly proven wrong lol, but hey, here technologies are very powerful. That’s amazing, and I’m really excited to se where this technology is in the future
Yes you did Alex! Lol Just imagine if you had more sun, I’m glad to see you got on to check it out thank you so much for watching it
You were probably thinking of one of those rip off “Patriot Power” units.
Thank you for doing this test. We’ve been thinking about getting a solar generator.
Thanks PJ I have more coming. Just trying to do tests that I would want to see and folks with limited knowledge to try and help
Thanks for this video. It's very helpful!
Thank you so much for your comment by the way if you go to the comment section and you go all the way to the top we pinned a new video we created with even more information that might be helpful
Nice test really appreciated
I got a question?
Can you do the same test but with the
River pro with the extra battery??
Thanks in advance
Thank you very much and also thank you for watching I don't have the extra battery for the pro otherwise I would do that test but I do have more tests coming with the other Delta units so stay tuned and have a happy holiday
Excellent video, just what I wanted to know. I am thinking of getting a Delta, but realise solar may not be the best recharging option for me as we mostly get outages in winter when it's overcast. Do you know roughly how long it would take to recharge from a car? Is the idea to do this while driving? I assume trying to recharge while your car is not running would flatten the car battery?
Thanks Sara, car is around 10 hours to recharge
Good Job. One of the more worthwhile test applications. My power outages have all been accompanied by bad weather -- no sun. I now have 3 generators; bought several years apart. Was considering a power station for peace of mind and maybe simplicity. It's clear there is little achieved and considering the cost it's not worth the bother.
Check out our video on the Delta Pro it’s definitely a heavier unit with a much larger capacity and the battery is a lithium iron phosphate battery I’m not sure if you’re familiar with that but that battery has a lot more lifecycles in it. Also what’s nice about that system is it can be charged by a smart generator and even an EV charging station.
Tip! Check your latitude and place the solar panels on the same angle as latitude, face the panels due south for optimum input.
My wife brought up an important point that I never thought about. At the end of the day, we spent $1600 on panels and a generator to save $200 worth of food for a power outage that may come once in a decade!
lol yep. better just to invest in dry goods and long shelf life food.
and just buy a cheapy version of these for phones, lights, laptops / tablets and little fans at night and fridges ( if you have special medicines or something dire needed to be cooled ).
solar will never run what people really want without spending an ass load of money. ac units, fridges, hot water ....lol nope not without tens of thousands of dollars.
gas will always be best for short term comfort... long term solar for necessity which would always be "light" and charging radios etc.
Well, you can use it for daily usage instead. Charge it solar, then use it for your toaster,oven, TV or laptops. You will be able to save some money on electricity bills.
Yeah, I think this is the major hurdle with solar energy in general and solar "generators" specifically. The ROI absolutely sucks.
The Ecoflow Delta is pretty darn amazing, and I am considering buying one; however, this test confirmed my concerns that it simply can't power much for any meaningful period of time... certainly nowhere near the length of time it would take to make the investment worthwhile.
With the cost of panels and a necessary gas powered generator to keep the Ecoflow charged as well as the Ecoflow unit itself, one is looking at spending, what...$4000 - $6000 maybe more?
The cost of maintaining convenience I suppose but let's be clear, this type of set up is not a cost effective approach to maintaining food in a power outage. What if you had a freezer or another appliance running at the same time? A gas generator would be have to be constantly running to keep the Ecoflow charged which begs the question, in a way, of why even spend the money to buy an Ecoflow.
Killer product concept. Not nearly enough battery capacity. Cost is a significant issue as well.
@@cbr8206 maybe need about 10 of those for daily usage. And these 3 solar panels are also not enough. Would need another 6-8 more solar panels to charge all the power stations
@@tanalson nice point. Only adds to my conclusion that the Ecoflow is not nearly enough bang for your buck to seriously consider. Maybe in the future.
Make sure the icemaker is off, and defrost is off in a power outagr (if you can turn these things off)... it also doesnt need to be plugged in 24/7. you can probably get away with a 2 hour on, 2 hour off, schedule to really increase the time.
Yup definitely appreciate that
I'm not sure 2 hour on or 2 hour off would really give much benefit, it would just mean during the 2 hour on period the fridge/freezer is going to run longer in order to reduce the temperature from a higher starting point. These modern fridges/freezers tend to work on the basis of more continual cooling which is why it only draws 40 watts but will do so longer or more or less continually, keeping the temperature steady with little fluctuation, rather than older fridges/freezers that would draw a couple of hundred watts, pull the temperature down quite a bit below that set, then turn off for a considerable time before needing to cool again. If the fridge/freezer only needed to run for 2 hours every 4 hours then for efficiency targets these days, it would already do that. But a good point about the icemaker and defrost, and some fridges/freezes have a holiday/ECO mode that lets them run at a higher temperature, which saves a bit of power, or you could change the temperature settings but you would risk food spoiling quicker. It depends on what the goal is, preserve the food normally, or just stop a complete defrost and a puddle of water.
Just leave it plugged in. The compressor will kick on and off as needed already. If you want to decrease the energy usage you can raise the temperature target for the freezer.
@@niktak1114 That was I was thinking. Raising it to the safest possible setting. As you empty the refrigerator items, move the freezer items down. The frozen item, that you will eat once thawed, will act as an ice block..
Thanks, I very appreciated you review, it help me a lot. Regards from Mexico
Wow.this is the best video ever about this amazing product..thank you so much...Im getting me one of these..👏👏
Thank you
Hey, I think you should have connected the panels all in parallel. The way you set it up, the 2 smaller panels in series are around 41v and the big panel still gives 21v. This will reduce the possible outcome of the panels. With all in parallel you should get way more than 200w at full sun.
Solar panels are set east to west according to what he said and showed..so the panels should be laid out north to south…top to bottom instead of left to right….the fence shades one panel when rising and the other is blocked by the house sooner with them this way.
Thanks 🙏🏻 for your patience
More coming and thank you Meran for watching 👍🏻
Really clear and concise video. Thank you so much. I've been wanting this set up but didnt know how to put it together or what I would need.
Thank you, if you have time scroll up to the top, I pinned a newer video that offers even more detail with a similar example.
@@TechMadeEzy Thank you so much! I will definitely watch. I'm in the UK and we are expecting future blackouts so this is all very useful info. Hopefully, Ecoflow ship to my country.
Yes UK from what I know is a country they ship to. Good luck I hope it goes well
@@piamadison5539 try uk.EcoFlow.com
@@TechMadeEzy will do.
Okay, as I understand this type of emergency is raise the temperature a few degrees say 40 degrees and turn off ice maker. If we try the next test go full EMERGENCY, limiting door opening, turn off ice maker and adjustment to fresh food section to food preservation temperatures with run time
James Tullis - His fridge-a-frator pulling less than 50 watts is twice as efficient as mine and his is a bit larger ! ! ! Your right on limiting door opening & add pulling the plug on the fridge to lengthen the off periods. Most all refrigerators 'short-cycle' to maintain a narrow temp range so by pulling the plug for longer cycles you increase efficiency. (It is way more efficient to have non-interrupted run cycles with longer off cycles at the expense of a couple of degrees on the high side & still the same 'off' temp on the low side) This method requires your involvement every couple of hours . . . but for 'EMERGENCY' situations is best. thanks, RH
During a hurricane we had large frozen water bottles and we pulled 2 out of the freezer section each day to put in refrigerator section, and everything kept cold (40*) about 3 days. I think you can leave refrigerator safely unplugged for several hours a day, or at night. We are in south florida and still had frozen items in the freezer at the end of 3 days….no power.
a generator is needed for off grid living even with super solar set ups. A few days of ugly weather zap a battery bank. I loved this video.
Excellent Test - Excellent Video. Thank You
Thank you
Nice test but not advisable to use a “cheater” adaptor when running your extension cord through your door with an aluminum base plate with ridges and running a grounded appliance with a metal enclosure. If you are going to do this in the future and a grounded receptacle is not available at least use a in-line GFCI between the power station and the extension cord. This could cause an electrocution hazard.
Has anyone commented on the REEL / ROLL of wire that creating a induction coil? This is a draw on the power used.
Thanks for all info
Thank you for this video, saved me a lot of research :) now i know not to go for the Delta, but to go for the max with extra battery for my usage :)
Seems to be a good unit for emergency power outages. It would last much longer by unplugging the refrigerator for short periods of time since it would keep items cold for up to 4 hours if doors are kept closed. Interesting test.
But then the fridge warms up and takes longer to reach desired cold levels. Would be better to just set fridge temp to lowest acceptable levels and keep on.
@@clintcarter lol, yeah well everyone should do what they feel best. We suffer through power outages here constantly and with a gasoline generator, it's best to run in intervals. We have done that many of times and never lost any food yet. If you feel running your's constantly, that's what you need to do.
@@jamielawson1534 Agreed. And using a generator would be a bit different and could see more of a useful strategy from intermittent coolings. I have a generator on propane ready for emergencies and using intermittent periods of power/cooling is the way I also planned to use it. Solar/batteries I still think would be a little different but maybe you’re right.
This may be a novice question, but why is there no mention of AMPS or VOLTS of these units as compared to a DIY 12/24/48 volt system?? Which voltage system is the Ecoflow in comparison?
Hi Clark questions are always welcome.
The ecoflow will have a limit of solar voltage input, that was mentioned during the beginning of the video, EcoFlow website lists the max voltage this delta 1300 can accept
Thanks for this, I live in S Florida so sun isn’t usually a problem. However, I lost power for about nine hours as Hurricane Ian skirted us and I was wishing I had a generator. After A/C, the fridge is probably the item I need powered the most, so this is very helpful.
If I live down there I definitely would have one of these battery power stations and at least a solar panel or two it just depends on what you're going to power. This power station in this video is kind of on the small side but still could be helpful
We have just delta too thank you for explaining how to do parallel great video
Great video, but I would recommend against using different types of panels together. You would probably make about the same power by using either the two 100w in series or the one 200w panel by itself. Different types of panels together will significantly lower the solar output wattage. Also, over paneling your system by twice what the power station is rated 400Watt on input for would have allowed it to be fully charged on the second day before the sun went down and prevented it from dying at 1AM.
Thanks for your feedback and thanks for watching
I agree with the overpanelling, typically you don't get rated power once you get it to the battery, figure maybe 50% if standard charger, and maybe 80% if mppt. While it is best to use the same panels, You can mix the panels and get more power as long as the voltages are similar.,ie a pair of 100 that have open circuit voltage the same as the open circuit of the 200, just put the 100's in parallel. I would suggest using a diode between though. Keep in mind you could do the same think using deep cycle lead acid and seperat inverter, and get about 5 times the ah capacity. These type "generators" are convenient but expensive for their capacity.
Your best bet is to run only the same size amp and voltage panels, in series for a long wire run. Mixing panels can limit power to the least performing panel or string. Had you been getting 350 watts your test would have lasted much longer.
Yes I would've run all 3 panels in series giving him the best voltage and lowest current, also not going over the max voltage of the Delta
Wow, if regular delta does this now the delta max which just arrived. So excited, been having horrible outages here (Tahoe). Very interesting video, amazing what these machines can do. Almost 3 days lasted.👏👏👏
Thank you silver stay in touch let me know how yours goes
These devices are advertised with a wattage rating, you can buy them and be fairly confident at exactly how much runtime you can get from any appliance. The Delta 1300 is operating as advertised. It can provide 1300 watts in 1 hour. If an appliance draws 1300 watts, then it would run for one hour continuously from a full battery. The formula is simply the [advised wattage of the power source] / [wattage of the appliance] = hours runtime. So in this example, if we assume the fridge is averaging 40 watts an hour, then 1300/40 = 32.5 hours of run time. This experiment gave around 38 hours runtime, so we can assume the solar panels contributed about 6 hours to the run time, so 6 x 40watts = 240 watts from the solar panels, which is pretty poor, but others have pointed out the panels were not wired optimally.
Nice test, thank you.
Thanks Eric
Hi: I found your video very imformative and well presented. The question I have, not knowing that much about rechargeable batteries, is after you concluded your test and the the battery was drained, was it fully dead or can it still be recharged? Thank-you.
Hi Ttara yes you can recharge them, all batteries have a limit of cycles, this Delta has 800 cycles then its at 80%
A cycle is when you fully charge and full discharge the battery, like your cell phone, hope that helped?
If you raise your panels to 90° to the sun you would improve your output significantly.
Thanks for the test
Thank you
Cool enjoyed watching, learned some good info, will help me in deciding what to do.
Thank you
Dude, for $1,200 you can put in one hell of a battery bank. Just saying.
That is amazing....you would need two of these...great to know...my budget will need tweaking to purchase two of these....
Thanks. I’m saving for one of these.
You're welcome and let me know if you have any questions I'll always try my best have a great day
