It’s pretty easy to do calculations to see if it would work but there’s just something about actual testing that makes things more fun
I just picked up my Delta 2 with the extra battery ($1200 total from Home Depot) and this really reassure me that I'm going to be just fine running my freezer and a couple other small things. I live completely off grid and feel like this little set up will help greatly. I'll be using a 240 watt panel and can add another if needed. My little Honda 2000 genny charged both batteries from 30% to 100% in about 1 ¹/² hrs. I'm already a big fan of this unit.
1200 for both....Nice!
I just ordered a delta 2 from ebay for $600 shipped. They had a coupon code. Should arrive in a week. This week I try to watch all the TH-cam on it.
Being from Puerto Rico, I know about surprise power outages. I have a small apartment and plan on getting an ecoflow very soon. Thanks for the video
Feels like we are about 2 weeks out from our first hurricane...
Yes in puertorico we def need this . And I would put an ice machine plug it have ice in case the the nevera shots off I have ice as well . I bought me a fan with charger n light 💡 I was happy with the solar fan . 😊know I need this 😊
The problem is that no company that I know of ships these solar generators to the island, so your're stuck buying them from local vendors there and needless to say they charge at least twice the price.
@@iberiuspolonius8591 so true I bought in Puertorico solar fan with light charger and fan amazing
Being an old commercial refrigeration mechanic, I have to tell you that 28 deg won't prevent food spoilage. It might be slower than out on the counter with no refrigeration. But somewhere around zero or even below is best. Supermarket freezers routinely produce minus 10-20 deg temp to preserve food and allow you to get it home on hot days without spoilage. Colder is better. Essentially you are slowing down the growth/movement of bacteria by making it colder. Colder the better.
Good tip. Thanks!
i do the frige thing ,, its on a timmer,, we go to be around 11.00pm, the frig runs till 2.00am and shuts off till 630 am ish, then runs all day,,i figured out this trick when we started out on solar,,the frig is closed from 11.00 to 630 so no need to run, same with other stuff you dont use ant night,, like our freezer,,and in the day i off set the timmers ,, so when the freezer is on,,, the frig is not
Well folks, this is how people with battery backed solar think. lol. Its not like being on the grid you really think a lot about how and when power is being used. Thanks!
Who would not want a 1024Wh power station that only needs 80 minutes to full charge, I know I want one for myself.
The full charged is on grid power
True
Good test, I experienced the same with my different brand solar generator when leaving a refrigerator plugged in the Solar generator turns itself off. To avoid this, plug in a low 4 or 5 Watt light bulb to the generator. This constant low flow will ensure the generator does not turn off when the refrigerator cycles, that's how I'm able to keep my Solar generator on when using appliances that cycle off and on.
Using a low 4 to 5 Watt bulb is nothing, plus adds light to a room while keeping refrigerator on.
That's a great tip! I think it is possible to tell the system to stay on under zero load but I will have to look into it. Thanks!
I received my Delta 2 today. Solar panels are still on the way, so I charged it up with AC. Plugged in my basement fridge to it and have not opened the fridge or freezer since then. 7 1/2 hours later I’m still at 70% charge! If you can avoid opening the fridge as much as possible and if you can hook up solar to it while it runs the fridge, you shouldn’t need to cycle the fridge on and off.
Susan, Yes, I think your right. Thanks!
Thanks for covering this use case! I just helped get a family member's fridge through a power cut with my Delta 2 + 3rd party 200W panel. Worked like a champ!
Took 3-4 hours of the fridge running at 120W to get down to temp, and then the fridge dropped to under 10W at idle. Very rarely needed to cycle on the compressor to cool it back down, as we weren't opening it often.
Even with only ~70W of power coming in (overcast and smokey), we were able to bridge the gap before the power company fixed the line.
One quality of life item, I got a 30ft solar power cable, so I could keep the Delta 2 inside and out of the elements while rearranging the panels out in the yard.
Tempted to get another 200W panel, just in case :D
That is great! A real life experience that worked as expected. I really like the 30ft cable idea for sure. I would definitely add the extra panel. You can't ever have too much solar. Thanks!
Juat got my Ecoflow 400W bifacial solar panels and I sleep so much better now. 👍 Labor day sale too. 31% off til 10th.
@@sickofgreyhatsYes, it is very nice and reassuring to know that your always going to have some backup power in an emergency.
Good to see that the Delta 2 once again proves that it is really powerful with 1024Wh of capacity.
This is what I needed to know about cycling the usage if using appliances like a refrigerator. I met a guy that even claims it can run off a washer with a couple of loads in tow . If that’s the case, that would bolster my use of the Delta that I have . But yes, this helps bring things into a better perspective. Thank you ! 🙏🏽
I personally don't like using my solar generator to run a washer. I don't like the agitation ramping the power up and down on the inverter like that. That said, It probably would not hurt once or twice in a pinch. Thanks for stopping by.
In all honesty, that is one really good power station. Charges in 80 minutes and has a 3000 charge cycle.
Thank you very much for this test, as with the most recent (Oct 2023) Amazon Prime sale, I picked up a Delta 2, extra battery, and 2 x 220w panels for this exact reason. Now (per a below comment's good idea), just need to have the panels arrive so I can look at them... then order the panels' extension cables so the unit stays indoors and the panels can easily be moved for maximum input.
Sounds like your all set for the next power outage. :)
My god how nerdy and wonderful this is! Oh my god how I love this video! Thank you! I have to buy one of these now! I'd like to see a test charging a hybrid car with the solar panel. My hybrid charges to full in about three hour from a normal wall socket.
Thankyou for the nice comment. I don't think you would want to charge your EV from this 220 Watt panel. It produces about 650Wh/day. So if your EV has an 80kWh battery, it would take about 125 days to charge it! Just divide the size of your car battery by about 650. This is why covering you car with solar panels is a bit of a waste of time.
@@HomesteadEngineering Thank you for answering. I guess I won’t be doing that then 😂 It’s a hybrid with only a 10,4 kWh battery but that would still take 65 days then I guess. Anyway… thanks again for the video. I enjoyed it very much.
Good video.. For that price I would get another pallet of panels were im at ... I know a lot of other people couldn't get that deal so they would be better off getting that delta flow... Keep it up brother good information can always help someone else...
Hey Dan, This Delta 2 will work great for some folks but like you say, everyone's situation is different so you got to go with what works for you. Thanks!
Great test ! Very interesting, Thanks. A great practical 3day review. Will be interesting to see whether these power stations will run other loads such as a microwave. Thanks for your helpful review 👍
Thanks!
When on defrost cycle it may go up to 500 watts for maybe 20 minutes. However it been programmed.
Thank you for a very practical review!
Thanks for stopping by. :)
This was a great demonstration. In summary as long as i have the solar pannels (not included) I can run indefinitively with good sun. Also, By only turning on the fridge a few hours a day I could probably run some lights and the TV indefinitively.
If the sun is shinning it will rake about all this unit has to keep the fridge up and running. To run more, I would get a 450Watt regular panel from a local supply store ($200). That would give you some extra power to play with. Thanks!
Great video! This was some really good info
Glad it was helpful!
every time you open the freezer door you let in warm air. a chest freezer would do better. . just keep a small load on to keep inverter on . cheap extra styrofoam sheets will make them work even better. even a blanket over when not running . great test
Good tips. Thanks!
I love this video, (new sub now). This gives practical hacks on how one can "deal" creatively with a modest solar charger.
I really appreciate this comment. I should probably do more work on creative ways to get by on a limited budget. Thanks!
@Homestead Engineering I feel comfortable getting the Eco2. Its expandable if I find I'm stuck, good support, proven company. I was leaning towards the AC200Max partially because of the 30A connection. I can get by without and getting the more portable Eco2 will allow my budget to get solar panels right off
Great video. Should have used the kickstand that came with the bifacial panel. Its interior is white and helps reflect sunlight to the backside of the panel. I have a Delta 1300 + 220 b/f panel. Haven’t done a solar longevity test as yours but my Delta will run my LG bottom freezer/fridge for 23 hours without charging. A real game changer.
Thats a good point about using the reflective stand. Thanks!
@@HomesteadEngineering the mirror was a good idea. That bifacial would probably do great on the snow
Also, try setting the Bifacial panel on top of a Mylar emergency blanket & I believe you’ll improve the reflective results on the backside of the panel. I use the Mylar blankets for my 2 Bifacial panels & I’ve been pleased with the results thus far.
I did not expect that power station to be that powerful and now I think I want one.
Get the Delta 2 Max with at least 1 400w bifacial solar panel for emergency refrigerator use, bcuz if you have 2 rainy days in succession, the Delta 2 with 1 220 bifacial panel will not cut it. The Delta Pro, if your wallet can take it, is the BEST OPTION for homeowners. 👍 Good luck.
@@sickofgreyhats A generator will suffice for dark days.
Use a mechanical timer to cycle the fridge off and on 3 on 3 off works really well.
Yep, I bet that would work nicely. :)
I was considering a Delta 2 for this EXACT use case. Thanks for confirming a single panel is enough! I'll get a second panel so I can guarantee the use of small electronics at the same time during their next sale.
You'll want 2 220W bifacial panels anyway, but for emergency fridge use, you want a Delta 2 Max with a 400W bifacial panel. If you have 2 rainy days in succession, the Delta 2 with 2 220 panels won't cut it. 👍 Good luck.
@sickofgreyhats thanks for the input! The 400W panel had bad reviews, so I went with two 220W panels, then spent the cost of another 220W panel on five 100W Harbor Freight panels during their Labor Day sale. These things are cheep enough I don't mind leaving them outside. I still have a dual fuel generator for longer emergencies in case the rain is very bad for more than two days in a row.
This is only the beginning of my adventure with Solar. I'm looking forward to seeing where this road takes me!
I have been on the solar path for about 7 years now. If I were just starting out, I think I would build out at least 12,000Watts of panels and back it with at least 30kWh of LiFEPO4 batteries. Then maybe add the EG4 18k to top it off. Something like this:
signaturesolar.com/complete-hybrid-solar-kit-12-000w-120-240v-output-30-72kwh-eg4-lithium-powerwall-14-000-watts-of-solar-pv-kit-e0005/
@HomesteadEngineering I have an HOA and they do not allow solar. Hopefully I can get it on the ballot for this year and we can change that! Alabama Power is also not friendly to solar... so the financial situation will take a bit to get there.
It would be interesting to do this test by cycling the fridge with an electronic timer, allowing the fridge to be on for 10-15 minutes of each hour. I believe there's a setting in the app to keep the Delta 2 from shutting down if the load goes to zero.
Mark, I think that would be the way to go. I was going to do that but all my timers are 2 prong and the fridge is 3. Not that hard to get around but I just did not do it. Maybe next time. Thanks!
@@HomesteadEngineeringDoesn't the refrigerator already cycle on and off depending on the setting?
So I've heard when I bought my Honda 2000w generator that if you ran the gen an hour in. The morning and an hour at night the contents of the refrigerator would be fine if you kept the refrigerator doors closed. I never tried it though. But I was thinking a small generator like that would work very well paired with that ecoflow Delta 2 for charging it quickly and fully. Thanks for your testing
Yes, pairing a small inverter generator with a solar generator is a very good solution that will solve most problems you are likely to ever have. I think you may have to run your fridge three times a day for 1 hour each to keep it going. Just my guess. Thanks!
What I do like about that Delta 2 is that I am able to connect my Delta Max extra battery to it.
That is a nice feature that really extends the use. Thanks!
I think all the Deltas can hook together, as long as the smaller one is hooked to the larger one. I even saw a video of a guy that had 4 different named generators to each other. He said he just wanted to see if it worked, and it did. 🤔 I wouldn't have thought of that.
Oooh I didn’t know that but now I think I’m fully sold!!
Thanks for for discount code!
Thank you for using my link. It helps support the channel. :)
Thanks for the video. I feel every power station should be tested with a fridge since outside of camping, people will primarily use it to keep food frozen. I was trying to estimate whether I should go with a ~750Wh power station or a ~1000Wh power station. Based on your test, I can probably get away with a 750 if I have solar panels charging during the day. Naturally I need to focus on the peak load when the fridge kicks on so the inverter can handle it.
I would look for the best deal on the bigger one just to have some cushion if it falls into your budget. Thanks!
Kind of off subject here but I keep hearing how the PV panels (in your yard) is "plug and play". Would you be able to use one or more of those panels to power the Ecoflow?
Len, You should be able to use any solar panel as long as it meets the input requirements of the Delta 2. I think they are 11-60VDC and up to 500 Watts.
th-cam.com/video/vnt4nF0RGEw/w-d-xo.html
I just got a two pack of timers from Amazon for about 15 bucks. Instead of like most timers that only turn off and on one time per day. This one will turn on, all day everyday, over and over again. You can program it to turn on for an hour and then off for a few. And then back on and back and forth. Sounds like that's what you need instead of plugging and unplugging it all day
Sounds good!
Hello,how do i look through a historical graph of inputs and outputs load? I dont see it in the app with my delta 2! Though i can see it in videos of other owners of ecoflow...
I have not seen that but please let us know if you figure it out. Thanks!
An interesting video. We've just received our Delta 2 and 220w solar panel, bought specifically to run our freezers during a power cut. The freezers have a 7-8 hr melt limit, if you don't open the doors. We plan to wait about 5 hrs into the power cut, run the Delta 2 for an hour or so, and use that cycle until power is restored. It's all a bit of a learning curve. I saw someone who put a bowl of ice cubes into the freezer at his off-grid place. That way, if he came back later and found the ice cubes completely melted (whether it later re-froze or not), he knew he had to ditch the food. We will have to adjust the app settings so the Delta 2 still runs if the fridge clicks itself off for a while. Can't comment on the solar panel as the UK weather has been so rubbish recently but we're looking forward to hopefully getting some free power and maybe even use it to power an aircon unit in the summer. Aircon? UK? Who'd have thought it!
That sounds good and similar to what I did here. You might want to experiment using a timer and see how that goes. Thanks!
Yes, a timer is a good idea, many thanks.
Great video! If I buy the same system, do I have to buy inverter? Or does the inverter part of the battery system? Thanks!
The inverter is built into the system
So it does power the fridge atleast. I bought a efficient smallish fridge but my magneto keeps it on for 5 minutes and then cuts out. Probably peak watts from the fridge
I just bought this exact. Set up. At. well botts. Trying to learn all I can this was a great video. For me. Glad to see a long extension cord. Was used. Is this video. Is there. a specific type I should purchase. Do I need any other cables. To run the 220 watt panel Have not took the panel out of the box. Yet. Purchase was for a freezer. And frig
Hello Vickie, Everything I needed to run the 220 Watt panel was included in the package. Note: I did run a long extension cord but I used a 20A (12awg) cord from my shop so as not to incur too much of a voltage drop. Most common extension cords are only 15A (14awg or even 16awg) so be careful with that. i.e. The shorter the cord the better. If I were going to run this setup on a regular basis, I would use no extension cord and just get longer wires (of the appropriate size) to run between the unit and the the panel.
Thanks!
@@HomesteadEngineering Where can I get the longer wires for the panel. Like in your video. My system came from well botts. Not sure they have the longer ones.
cool test.
Thanks!
My question is, can i use eco flow to give charge to My 30 cu ft refrigerator, but 24/7 forever, for the life of the refrigerator or only i can use ecoflow for emergency
I just bought a second 220 bifacial panel as they had a great sale -I am interested to find out the capabilities with 440 watts of panel
Yes, The closer you get to the 500W max the better.
How much did the 220 cost in the sale?
the trick is to have frozen gallons of water in the freezer to keep frig cold during a power outage.
Probably a good idea to freeze gallons of water if you see a storm headed your way. Thanks!
good vid, if you turn off the AC time out to never on the app the delta will not shut is AC power off.
That's a good tip, Thanks!
No problem, and your welcome !
Just my opinion if you are going to the trouble of getting a delta Atleast stretch to the max or 2 max having twice the capacity is invaluable
Yes, The bigger the better and trust me you will ALWAYS want more. I now have 13,000 Watts of panels and 30kWh of battery and every day I am looking for a good place to add more! :)
So that’s just with one 220w solar panel. Would 2 220w solar panels be enough to run 2 full sized refrigerators then? I’m new to this so I’m not sure. I just got them both for $999 on prime day sale. Maybe by next year I can double everything since there is a plug to connect additional batteries and up to 500w solar
Depends on how much power your refrigerators uses but I think I could run two of these (like in my experiment) with two 220w panels. Like you said, you might need to add the second battery. Here is my review of the Delta 2: th-cam.com/video/vnt4nF0RGEw/w-d-xo.html
Note: Be careful how you connect your two sets of panels to the unit as not to exceed the max voltage or current limitations.
@@HomesteadEngineering I’m pretty sure the max is 500w
@@happyhamster1411 500w is the max power but you need to know more than that. You also can't exceed 60Volts OR 15 Amps. Note: connecting panels in series increases the Voltage and connecting them in parallel increases the current (Amps).
@@HomesteadEngineering I’m unsure what series and parallel mean. What if I want to use the ecoflow panels, would I be able to use 1 220w and 2 100w together?
How did you come up with the 75% efficiency? I just saw another test using a 1500w heater and the delta 2 ran for 28.5minutes which is 85% efficiency. 90's is great, 85 is good and 70's is considered poor. Is it software or hardware?
I got that number from other sources. I don't think that hooking up a heater and running for a period of time is a good enough test. You need to measure the actual kWh delivered on a meter. Also, the rate that you drain the battery will effect the results. I may perform a test at some point to see how mine actually performs. Thanks!
The inverter of the delta pro is a power draw when it's on. From my testing it takes ~20w/hour so the lower the draw the less efficient it is. My main draw for my off grid system is actually the inverter itself as my fridge takes ~16w/hour (chest cooler)
Duration is a factor a capacity test with a heater only lasts a hour so inverter running watts hardly get into the equation the inverter alone will use about 15% of the battery per day just for being switched on with no load
Instead of cycling the fridge, you can adjust it's thermostat.
You could try that and it might work but remember that the inverter burns power even when its idling so off may be better. You also want to get it as cold as possible when you have the sun shinning. Thanks!
What would the additional battery do to the equation?
I don't think that would help much as the limitation is in the collection. I would probably go out and get a single (11-60V) 450 Watt panel from a local supplier with no shipping cost. Maybe $200 for the panel. That would make a big difference.
Nice experiment though. It might be better to get the extra battery ecoflow sells for this unit and get more solar panels to provide all you need.
Yes, max out the panels and add a 2nd battery and your good to go.
Keep in mind “Refrigerator” has a defrost cycle every 24 hours (in my case) defrost do use a lot of power in more watts added to it.
If someone knows how to hack and add a bypass switch to the defrost device, please share.
Good to know. Thanks!
problem is in europe cost comes25% higher to buy em .. same prices without a good panel and cable... dunno why
Could be some kind of import tariff issue...
when you are using the solar, do you have to have the delta 2 near the panel?
The cord that comes with it is pretty short but you can buy an extension. I run mine off a 50 foot extension out the window so the unit is inside and the panel is outside all the time. I run this unit everyday.

@@HomesteadEngineering thanks so much for sending a link! much appreciated.
Their is a problem using extension chords with refrigerators. Can ruin the fridge and start a fire.....
Well you don't want to have too much of a voltage drop but I did use high quality (20A) cords.
ThIs is GREAT I only need to figure out how to get 220v welding capable.
Why would you need 220v welding cable?
I am not sure what was the objective of the exercise by plugging in and unplugging the fridge and also turning off the Delta2 unit.
The point was to see if the Delta 2 solar generator could back up the refrigerator. I cycled it to save power and that worked. Could I have just left it plugged in and turned on the entire time? Maybe...
@@HomesteadEngineering ok. Point taken.
I thought you would have just left it plugged in.
What panels are you using? link please. Thank you.
I would probably go out and get a single (11-60V) 450 Watt panel from a local supplier with no shipping cost. Maybe $200 for the panel.

Keeping the door open cut the time way down.
It will cut the time down every time you open the door. That said, you need a realistic test and the door is going to be opened in a real world scenario.
May want to oil hinges
lol, I knew someone was going to say it... :)
😂
Can you buy any panel to charge it?
You can buy any panel that meets the specs. I think its 11-60V, 15A, 500Watts max and MC4 connector.

So you could probably cycle off for 5 hours and on for 2 hours. Be interesting to repeat the test in summer, won't be able to turn her off for as long but on the other hand the night will be shorter :)
Yep, lots a ways to make it work. Summer should turn out better. Thanks!
Just turn the fridge off for 5 hours a day and let it charge back up. ADJUST for sun
Im still doing my review before getting one of these ecoflows. Do you like yours ?
I am very happy with mine, I actually use it almost every day.

@@Sjrick These small solar generators are not designed to run large appliances. They are good for small electronics and camping and stuff like that. If you are looking to run more of your house in a grid down situation you are going to want to start thinking much bigger. Figure $15k for a real whole house system.

Im new to all this so thx for your input.
If the delta shut completely off you must have eco mode on
OK, Thanks for the tip, I will have to look into that. :)
As long as the sun is shining ??
Yes, With the sun shinning it takes just about all this unit can do. If you really want to hold up a refrigerator, I would go bigger (more solar input and more battery). BTW: I use this unit every day. Its running a window AC right now. No issues so far.
can i put in a washing machine;
It may run a washing machine but I would not use it for that purpose. Thanks!
I wanted to ask something else, I tried to fill it with a Hyundai 3500 generator and it didn't give more than 30 watts, do you know why?
What exactly are planning to cook on? You have no power!!! Hope you have gas, or barbeque. Then whatcha gonna do with it, you still have no refrigeration???
Check this out: th-cam.com/video/-Oevm6bxnp0/w-d-xo.html
Why would you unplug the fridge just leave it and see what happens
As a test. Its a spare fridge with only water in it.
other words ecoflow will not work like having full size batteries and 12volt fridges as they have inside the vans
I don’t see the purpose of cycling the refrigerator on and off. If the panels make enough electricity to fully charge the Delta on a sunny day from a very low charge level, discharging it to 40 or 50% and letting the refrigerator sit there unpowered for hours then turning the generator back on only to drop the temp. of the refrigerator back down to what it was before you shut it off makes little sense to me. This is especially true if the generator is fully charged while there is still sun. Then those panels are feeding the generator more power while the sun is out than the refrigerator needs to run. It is theoretically a waste.
I have a small Bluetti unit that I have conducted some experiments with and I have a Delta 1300 on the way. I will have a total of 6 100 watt HQST panels which I plan to run 3 in parallel with the other 3. This may be overkill and overload the generator. If it does, I will just run 2 in parallel with the other 2. It will be nice not to toss all my food in the refrigerator away after a hurricane.
I am also looking for advice on charging one with a non-inverter gas generator. Of course I would connect a quality surge protector between the gas generator and solar generator.
I think there are several ways to make this work. I do think you are better off running the fridge the entire time that the panels are in the sun so as to avoid charging and discharging loses on the battery. One solution is to simply use a bigger system.
As for the dirty power charging with a surge protector: I can't say for sure but I really don't think a basic surge protector is going to help you. It takes some pretty expensive equipment to rectify a dirty signal into clean power. I think your better off just using clean power from an inverter generator if your going to power sensitive electronics.
Thanks!
I just finished my own solar experiment with a Delta 1300 and 4 rigid 100 W HQST solar panels. I put the panels on the roof of my screened in room which gets sun about 70% of the day while the sun is up. I started with a fully charged solar generator. Day 1 was a good day for solar and I was at 76% when I went to bed. Day 2 wasn't so good and I shut it down after 48 hours in the early evening even though I had over 70% charge left. I conducted a second experiment with my Bluetti AC30 300 Watt solar generator and 1 100 watt panel and an in-line meter. I had completely discharged the unit. During the whole day the meter showed that I only charged 170 watts back into the unit. It was threatening to rain all afternoon.
I already knew this, since I conducted a similar test shortly after I bought the Bluetti a couple of years ago.
At the same time that I bought the Ecoflow Delta 1300 I bought a 3500W gas inverter generator. Ecoflow recommended that I not use my old generator. I can easily charge the Delta 1300 twice on a gallon of gasoline plus perform some other chores with the inverter generator. I'll still use less than a gallon of gasoline a day if I only use it when needed. The generator is quiet and costs less than the Delta 1300. The generator is made by MaXpeedingrods and there are reviews of it on youtube.
I have been without power for several days after a hurricane and l think that this is a less expensive approach than buying a much larger solar generator and hundreds of dollars in panels for a natural disaster. If you live out West where the sky is not cloudy all day you can rely much more on a solar only setup. Here in South Florida where the days are partly to mostly cloudy I think an inverter generator is a great backup to solar.
Thank you for your video. It was a realistic application of what one would use a solar generator for. I have thrown all the food in my refrigerator away on 3 occasions after storms, at least all that I couldn't eat before the food went bad. In the past couple of days the news has reported hundreds of thousands without power because of storms in the Northeast. I'll bet a lot of those people would pay a premium price for a fully charged solar generator and some panels.
OH MY GOD! YOU DON'T KNOW WHICH SIDE OF A SOLAR PANEL TO USE? Seriously, you turned the bifacial panel AWAY from the sun? 😔 It's NOT a real test then, bcuz the rest of us turn our SOLAR panels TOWARDS the sun.
Yes, the two sides of this panel actually look pretty similar and so I did have it backwards for part of one day. Even so, I think the test gives a pretty good idea of what you can expect if your trying to hold up your fridge.
how long will it run small appliances like a LED TV, and a few LED lights? i want a how long will the full battery last test for small off grid use.???
It all depends on what you plug into it. It has a 1kWh battery but lets call it 750Wh after loses. So for example, it will run 75 Watts of stuff for 10hrs. It would run 7.5 Watts (LED Bulb) for 100 hrs. Check this out: th-cam.com/video/vnt4nF0RGEw/w-d-xo.htmlsi=HiRw9rZOsn7kmKvC
Check out their rating with the Better Business Bureau before buying. I wish I had.
Di you have a problem with the Delta 2?
@@HomesteadEngineering No...I had ordered the DeltaMax 2000 +220w solar panel. Never received the solar panel. They say I did not add the solar panel to my order. Yet, the ad stated DeltaMax 2000 + 220W solar panel and had a picture of the two items together along with the phrase "Black Friday". My receipt even says DeltaMax 2000 + 220W solar panel. When I called the company to ask where the solar panel was they told me I was not the only customer to complain and that if I wanted to return it they would subtract a $70 return shipping fee and a fee of 3.6% of the purchase price because I had used paypal. The total out of pocket would have been approximately $150. When I filed a complaint with the Better Business Bureau I saw numerous other complaints against this company. The Better Business Bureau attempted to contact the company twice but Ecoflow did not reply to their inquiries.
The Ecoflow companies rating on the Better Business Bureau website as of yesterday is an "F". I believe this is the worst rating they give companies.
@Mike Dunning happy to help Mike.
@@DaveC-sx3gl This is true Ecoflow sucks in customer service.
Wow. 😲😲😲 I must be doing something wrong. I only got 4 1/2 hours refrigerator time from my Delta 2!
I'm not happy with it at all.
I also bought just one EcoFlow 220W Bifacial Portable Solar Panel. When I hooked it up, it told me it would take 28 hours to charge up the unit, and it was noon with no clouds in the sky. I understand 220W is just a fraction of what the unit will take, but I was hoping for better than 28 hours. I even made sure I had the panel facing the correct direction. I also didn't realize you could put an extension cord on the panels. That's handy.
Is there someway to program the unit for more efficiency? I just took it out of the box, charged it up, and plugged in the fridge. @HomesteadEngineering
Lets dig into this a bit:
1. How many Watts were you getting from the solar? You can see this on the screen when charging. Should be about 180ish in the full sun.
2. How much power does your fridge draw? you can measure this with a meter: amzn.to/4brfi8S
Those two things will tell us a lot.
@@HomesteadEngineering
on the Delta unit, it showed 175 when the fridge was running, and 35 at idle.
I don't have one of the little meters yet that I can plug straight into the fridge to show the wattage.
The solar panel was in full noon sun, I made sure it was facing the right direction, and it showed 87 input.
I was not using the unit while trying to charge it with the solar panel. I just have the short cord that came with the panels to plug it into the unit, so I actually had to drag the unit outside to charge it. I need to look into getting an extender.
Just picked up the Delta 2 off Amazon for $650! We are fully off grid and I think this unit is going to be a game changer for us. This review was excellent and provided so much helpful information. Now I just need a solar panel for it.
Wow, great deal! I would get a low cost panel that maxes out the input Wattage for your unit. Your going to want all the solar you can get! :)
@@HomesteadEngineering yes, we don’t get much sun this time of year in Alaska. Glad it comes with a car charging option.
