Good test! According to the manufacturer’s utility usage, the freezer should-under normal circumstances-use 249 kWh per year on average. That would average 0.682 kWh per day. So…ignoring the inefficiencies of the inverter, under normal circumstances, a 100AH battery should be able to run the freezer for almost two days.
That is probably correct. I plan on doing the test again once I have the freezer 1/2 full. That way I can do a good example of a power outage with an already frozen unit with 1/2 capacity. I hoping to get another 10 hours at least! Thanks for the comment.

Thank you for your review Confirms my results I've been through gas fridges 12v fridges galore in my off grid setup in NSW Australia But found with todays energy efficient stuff Oz mains 240v fridges and freezers are the way to go My 240v fridge only 242L hisense 175 kwpy And it's mate a 155L upright freezer 228 kwpy Run fine for nearly 2 yrs now on a 400ah bank of 24v flooded batteries with a 2000w inverter And another 100L freezer on another bank People always mention inverter loads as a negative but if your off grid the inverters on 24/7 anyway With 12v gear its good but you have to clean the fan and radiator yearly as they block with dirt and grime and lose efficiency
Yes. That freezer is actually plugged in to my 24v 300a system and doesn't have any issues and the system runs it with absolutely no problem. Thanks for the info!
for fun i just used my jackery 300 and plugged it in with a fully loaded freezer of the same size thats been at zero for months. it used 3-5watt. it was useful to see yours from warm to cold as thats the max we are going to need just in case.i am building a custom battery for my backup so needed some measurements as well.
It really is! I'm planning on the doing the same test with an already cold freezer that actually has frozen food in it. It will be interesting to see the results. Thanks for the comment!
Thanks buddy. I like how you take the test to the end while updating on the readings. Helps alot for someone looking forward to similar projects. Worth it 👍 💯
You sort of indicated that you might be running your freezer on solar to make it free, but you also seem to be experimenting to see how long a charged battery would last if you lost power and the sun didn't come out for days. I think that you will find, if you wanted a dedicated emergency power source for JUST your freezer, you could use a 700 or 800 watt inverter instead of the 1500 watt one and you'd get an even longer run time. The bigger the inverter, the more energy required to just run the inverter in standby (when the compressor shuts off and is just waiting to cycle back on when the freezer warms up) The type of inexpensive inverter you're using isn't very efficient, but by sizing the output of the inverter closer to the needs of the freezer, you will extend the run time. This will be especially true when your freezer is full of frozen stuff and will be spending most of the time in standby, and you'd just be burning up juice to run a large inverter that isn't really doing any work for you during those periods. Of course, if you have other things connected that run all the time, that would be a different story. The best way to power refrigeration with emergency equipment is to monitor the inside temp and turn the inverter on and off at regular intervals manually. It's more work, but the battery will do the most good that way. You can even chart the on/off time now, during a non-emergency, make a note of the interval and then replicate it manually during an emergency. Throwing quilts over a small chest freezer like that, if it's full of frozen food (keep any unused space filled up with frozen water-filled milk jugs) will require very little cycling for 2 or 3 days.
This is very good, I have family that live in the Axton,Danville Virginia area,When the power goes off, it's off for 2 to 3 days when a strong storm hit.Thanks for the demonstration.
I would love to see how you set that battery up with the drop on rig. Looking to set myself up with 2 100ah lifepo4 batts and interchange them as needed in power outages for my refrigeration. Ideally one charges while the other is in use. Anyway I'm looking to rig mine like that for portability and relative ease and neatness going from battery to battery...thanks!
i keep a old couch cushion on top of our chest freezer. seems to help. going to put styrofoam around the basket to top to make a small fridge inside. hope it works👍👍
Thanks I recently bought 100 ah lithium iron phosphate deep cycle battery and have been wondering what it can do I'm new to this so I'm going at this blind and you were a BIG help thanks again
We will be running a similar sized freezer off grid. The switch on surge appears to be about 750 watts for a few moments. The Inverter (700W Nomad) is rated at 1400w surge, so should handle it. It should do well in summer with sunlight. (We will have 2 x 160W facing E-W on opposite sides of roof with 200Ah of Lithium batteries.) We may need to upgrade to another battery to cope with winter doldrums here in NZ.
Great stuff bud . Question: if I only open the freezer once a day is it possible to leave it plugged off throughout the evening and early morning ( 9 pm - 9 am) I hear it remains frozen for up to 24 hours once plugged off ?
Yes, absolutely. The more frozen items you have, the longer it will remain frozen. You need to test it first. Some freezers aren't as insulated as others. You don't want to get food poisoning from thawing and refreezing everyday.
~1 kwh/day to maintain a fully loaded chest freezer. You could just charge it while you have solar power and unplug it at night. If it's relatively full, you set it to the -4 deg C and you limit the amount of times you open it at night, I doubt it'll get above zero before the sun comes up. With about 500W of solar panels, you can run this with minimal battery draw.
I have 4 one gallon jugs of water in the bottom, provides thermal stabilizing mass and as a last resort 4 gallons of drinking water. Other advantage there is no defrost cycle like a refrigerator.
No. Do you have something in mind that you microwave daily? It would also depend of Microwave size and inverter size. I would need a bigger inverter to power a microwave. That, in turn would increase the amount of loss from the inverter. I could look into it. Thanks for the question!
I don't know if I missed something but you're also using an inverter? Step by yep would have helped me. I'm seeing so many variations of off grid power.
Yes. The inverter is the blue piece of equipment on the side of the battery. I plan on doing a follow up video on a a FULL Freezer. In that video I will show step by step on how to build the 12v system. Thanks for comment!
I like to give credit to Andy from the off grid garage for that. Check out the link for all that information. off-grid-garage.com/victron-connect-through-raspberry-pi/ I hope it helps!
Nice testing! Ibe been doing some experimenting with my battery set-up as well. I noticed that on about 1500w load from a water heater, i noticed a 1 to 1.5V voltage drop. Have u tried and observed how ur battery voltage would drop on a 1.5kw heater load?
I've never measured the voltage drop on large loads since I really don't constantly draw anything larger than 500w at a time. I need to test out the difference in the voltage drop in a 12v setup compared to a 24v setup and 48v setup. Thanks for the comment!
@@OffGridBasement looking forward to your test results will be very interesting. I have a Redodo 24v 100ah battery. I wonder how it will compare to ur 24v chins. I saw one video saying using the victron lynx system (less resistance due to less wire cutting l, crimping, etc) will lessen the voltage drop in a solar system.
What would be your new choice of inverter since you said 1500 was overkill. This is what I'm looking for but need the construction instructions and would like to be able to charge the battery with solar and propane generator. What parts would I need? This is really what many are looking for instead of buying another solar generator.
It's pretty difficult to tell you what you need. You could check out my website. I have a simple 12v off grid system diagram and my more complex 24v setup. off-grid-basement.com I hope this is a good start. Thanks for the comment.
If the electricity went down for weeks, could you charge up the battery again and if so how long would it take? Would you be better to have 2 batteries and alternate them? Also can you continuously use the interverter? How much does it all cost. Sorry for so many questions but I know nothing about all this. Thanks.
You are honestly asking about things that have so many different factors involved. I could write a book on answering that! Maybe I'll make a video on how to find that all out. Thanks for the comment!
Of course you did not have the solar panels plugged in so it would run indefinitely otherwise. What size panel would be suitable if just running the freezer?
hello good video I have a question , I have the same size freezer , also battery 100a for solar panel , I want to use it for camping for the summer , a panel can charge enough the battery and work all the summer like this only for 1 freezer on this size like yours ? ? and if yes what size of panel I need? thanks a lot
Thanks for the comment. Usually you can achieve 5 hours of good sun a day. Summertime will be longer. I believe you would need a 200w solar panel and a 20 amp solar charger controller in order to keep that freezer running throughout summer. Hope this helps!
92V is kind of scary to me but the motor probably doesn't run long enough to harm it. Lower volts pulls more amps. How many watts does your inverter use on standby? It would be a pain in the rear to remember but you might be able to extend that time by deciding when the freezer cycles and turning the inverter on and off every 3 hours or so in an emergency.
It turns out the inverter had a blown capacitor. That's why the voltage was so low. Most 1500w inverters use around 8w of standby consumption. Hope this helps!
i been curious about this myself. i just bought a high efficiency 3.5CF and 2 100AH batteries for cloudy days. i got 2 Renogy 100W solar panels to push it. its not yet arrived in the mail but i think i possibly may need to double my solar panels, just a hunch there.
Just saw your video and what a great timing. I've been thinking of buying a freezer but am still undecided on whether to purchase the 5 cu ft. or the 7. Since it is my two of us I'm leaning towards the 5 cu ft. Seeing that that 7 was so efficient I am hoping that the 5 cu one will be just as much. Gives me a piece of mind that a 100 ah battery ran it that long empty. I have a couple of ecoflow delta max 2000 that I can hook up to and use as an EPS for when we experience a power outage which is frequent in my area. This is good information to know especially when we travel and are gone for several days or weeks. I know that my ecoflow powers my residential fridge for 17 hours by which power returns but the freezer that will have all my expensive meats will be a game changer with how efficient it is. Thanks for sharing.
You're welcome! Also, the freezer will run much longer when it's got food in it. I've heard of you put 1\2 gallon jugs of water at the bottom, it makes a big difference. Thank you for the comment.
I have a similar Freezer and it refuses to run off my Jackery 500 or my Bluetti EB3A. It does run off my DIY solar system that has a 3000 Watt Pure Sine Wave Inverter. You would think 500/600 Watts of power would be overkill to run the Freezer, but nope wont do it. The freezer did come with a caution wont run on solar generators, can you believe that lol.
@@mannyfragoza9652 yes thats why it so good to test now while you can. You will need a lot more power than you realize for everything. With all of your batteries assume 80% when planning
I believe you would want 200ah battery, 30A charge controller, 1000w pure sign wave inverter and about 400w of solar panels. You're looking at a minimum of $800. That is just an educated guess. I hope that points you in the right direction!
I'd love to see this redone with frozen food and thawed food. How long do they last before they go bad... plus the aspects of adding different liquids, liquid oxygen, nitrogen, and dry ice... how long will they last before it thaws out because there's an outage. Another would be about the time needed before you had to restart the freezer to keep the food frozen/cool enough to last long... Cheers!
Oh ya, what's your protocol/s on battery fires... and any bad products from Amazon, related to creating those same fires... since they love to sell like the other websites... lol Cheers!
I personally don't think so. I have enough solar and battery backup to run my freezer. I also wouldn't want to constantly need propane. They are a very good option for RVs. Thanks for the comment.
The big users of power in a refrigerator are the initial cooldown of the machine, and the freezing of content that was bought or harvested fresh. All you need now is a solar charging system.
For a 48v configuration I believe you need at least 60v of panels. If you connect four 12v panels in series that should be good enough. Hope this helps. Thanks for the comment.
I have the same freezer you do. I am considering buying a OUKITEL (CN505) 614.4Wh LiFePO4 500W Solar Generator. My freezer when full is pulling about 55wt. Based on your numbers (32 hrs on a 100wh battery...the OUKITEL unit providing 500wh (figuring about 80% realistic capacity) should run my freezer for over 6 days??? (5x32=160hrs) Is my math correct? Or am I missing something... EDIT: I did just read below where a guy was unable to run his freezer with either his Jackery 500 or my Bluetti EB3A. What's happening there? Are these inverters too weak? (surge capacity?)
If I'm reading this correctly the OUKITEL has 614wh. This freezer was running on a 100AH battery. 100AH = 1280Wh. That would mean your 614Wh solar generator would get about 16 hours of runtime not including the loses from the inverter. Realistically, the power station might get about 12 hours of runtime if it works. Hope this helps! I have a Bluetti EB3A, but I've never tried to run the Freezer. I really think it depends on the freezer on whether it will run from a Jackery or EB3A. I think you correct in the surge being too much for the solar generators.
I'm just going by the results of the shunt connected to a 100ah battery. I figured you have about half of the storage capacity. That would mean roughly half of the time.
That is genius! That would be great for the people that insist on unplugging the unit to save energy. If the quarter drops, it's been unplugged for too long! Good thinking and thanks for the comment!
Hello. I have a ecoflow delta pro. I'm confused about how long I could run a freezer like this to constantly be freezing ice for an icy breeze. I have a wave 2 and it's dangerous and failing.
The ecoflow delta pro has about 3x the capacity of this 100ah battery. Ecoflow = 3600wh Battery in video = 1280wh I would say you should be able to get at least 80 hours of freezer run time. Hope this helps.
a freezer with less than half its capacity used is showing most use of power- learned that in 70's.. my own freezer is twice as big but the usage is comparable..yet, my freezer has actually frozen at the compressor if run too empty- so I run it with water jugs often times between meat loads. One day I will get a 12 or 24 vdc freezer
I actually have a 2000 watt inverter on a 100 amp battery running with a chinese small charge controller and two 100 watt panels and it is on six months running fine for a fridge and a freezer.. normally holding 40-50 pounds chicken.. no problems
@@brotheradam hey I appreciate that info. I'm on here because I'm trying to set up a system to run two small chest freezers on a solar system some of what you just stated.
Maybe 18 hours: V x amps = watts. 12 x 900 (running amps) = 10,800 divided by 600= 18 hours. However, doing this would draw your battery down to zero amps which will kill your battery if you do this often enough, even if its a deep cycle battery.
Yes that is always interesting to know That's the real killer I run a 155l upright freezer and a 242l fridge only on 240v on a 400ah 24v bank fully off grid here in OZ Temps between minus 6 Celsius in winter and positive 46 Celsius in summer I started with a 1200w pure sine wave Giandel inverter But on the odd times both started up together it would trip the inverter Both are only about 50/60w running current Changed to a 2000w model and all runs fine So definitely something to consider Cheers
@@OffGridBasement I wrote GE about the specs on that freezer (we have the same Hotpoint model). Their reply: "I apologize for the wait on this information. Your freezer’s running wattage is 195.5 watts and the surge wattage can be from 2-3 times the running wattage. I hope you have a wonderful weekend. Thank you for contacting GE Appliances." That would mean you need 600w minimum surge capacity. Not understanding things electrical...I'm wondering why if the running wattage is 195.5w, why does my power monitor show it's using 50w -60w??
An empty freezer will take a shorter time to get to a constant zero °, so unless everything you fill it with is already below zero ° it will take over 12 hours for it to reach zero °.
I’m a little older and have had a few freezers . Usually I was told never to run a freezer empty , first off , for what good reason, always at least a 5 gal pail three quarters full , one to see how well the freezer works, second to help maintain the frozen atmosphere, like a cooler or an ice box . In what scenario would it be used empty ?
It shouldn't! I wanted to show the worst case setup. This amount of time should be the LEAST amount of time you would get from a freezer. Most would have already been frozen and probably at least 1/3 full if not more.
I'm sure it would work fine. The compressor probably doesn't require too much more power. If it's possible to find out what the surge wattage is, that would be best.
You're right. This is a very basic freezer unit. I bought a freezer that I figured the average home owner would purchase. Thanks for the comment and information.
well you should have told people that in your video so they know, its a huge difference, just saying. I also run a 7 cubic ft chest freezer with a external thermostat so it runs as a fridge, great energy save as it opens form the top where warm air goes and its way better insulated than a standard fridge. external thermostats cost 6o bucks. have done this for over 25 years@@OffGridBasement
@@OffGridBasement I have a 5000 watt modified and now they are saying it will burn out a fridge or chest type freezer, it takes two batteries to get the 5000 watts, but if you keep something charging the the batteries, it will run ever thing in the house at the same time (110-120 of course) power house but now has me worried to use it, what can you tell me about this modified sign wave inverter
@@randybird9979 I do know that modified sign wave is harder on anything with a motor. You could get a smaller pure sign for just the fridge. I've found a 1500w does the job just fine. Hope this helps.
@@OffGridBasement I been thinking I need to get a pure sinewave , I have used the modified sinewave for fridge, but not much only when electric went off, thanks for the info
Oddly, your 1500w inverter used to drain 19 watts from the battery without AC load, and now with a freezer when compressor is off, it drains only 12.5 wattss from the battery.
Hilarious 50% of your electric went to the 1500 watt inverter. You probably would have gotten 2 days with a matching inverter. And if you had frozen water jugs you would have probably gotten 4 days
92vac input is a bad thing. You may want to check the input with another meter just to be sure. It'll run but the low input voltage will definitely reduce the longevity of the freezer. Possibly much sooner than you would think, no way to know. Good luck
You definitely can. The freezer in the video is powered by my 24v system. 300ah and 1.8k of solar powers it 24/7 with no problem. I plan on doing some things with a 100ah battery and a 180w solar panel soon. Thanks for the comment.
When i made that comment in the video I was only talking about myself. All of my equipment is 100% paid for. I understand what you are saying, but in my case it was true. If I had a 20 year loan on a whole house system I would never say that. Thanks for the comment.
@@OffGridBasement regardless, you must depreciate your equipment and do the math and you will find that it is the most expensive electricity on earth by a long shot.

Confirms my results
I've been through gas fridges 12v fridges galore in my off grid setup in NSW Australia
But found with todays energy efficient stuff
Oz mains 240v fridges and freezers are the way to go
My 240v fridge only 242L hisense 175 kwpy
And it's mate a 155L upright freezer 228 kwpy
Run fine for nearly 2 yrs now on a 400ah bank of 24v flooded batteries with a 2000w inverter
And another 100L freezer on another bank
People always mention inverter loads as a negative but if your off grid the inverters on 24/7 anyway
With 12v gear its good but you have to clean the fan and radiator yearly as they block with dirt and grime and lose efficiency

What would be your new choice of inverter since you said 1500 was overkill. This is what I'm looking for but need the construction instructions and would like to be able to charge the battery with solar and propane generator. What parts would I need? This is really what many are looking for instead of buying another solar generator.
It's pretty difficult to tell you what you need. You could check out my website. I have a simple 12v off grid system diagram and my more complex 24v setup.
off-grid-basement.com
I hope this is a good start. Thanks for the comment.
If the electricity went down for weeks, could you charge up the battery again and if so how long would it take? Would you be better to have 2 batteries and alternate them? Also can you continuously use the interverter? How much does it all cost. Sorry for so many questions but I know nothing about all this. Thanks.
You are honestly asking about things that have so many different factors involved. I could write a book on answering that! Maybe I'll make a video on how to find that all out. Thanks for the comment!
Of course you did not have the solar panels plugged in so it would run indefinitely otherwise. What size panel would be suitable if just running the freezer?
500-600w of solar panels would easily do the trick IMO. If you have good sun everyday then 300w would do it. Thanks for the question.
hello good video I have a question , I have the same size freezer , also battery 100a for solar panel , I want to use it for camping for the summer , a panel can charge enough the battery and work all the summer like this only for 1 freezer on this size like yours ? ? and if yes what size of panel I need? thanks a lot
Thanks for the comment. Usually you can achieve 5 hours of good sun a day. Summertime will be longer. I believe you would need a 200w solar panel and a 20 amp solar charger controller in order to keep that freezer running throughout summer. Hope this helps!
@@OffGridBasement sure it helps , thanks a lot for this , in my country (Greece) we have a lot sun days and for this I want to make a set up .
92V is kind of scary to me but the motor probably doesn't run long enough to harm it. Lower volts pulls more amps. How many watts does your inverter use on standby? It would be a pain in the rear to remember but you might be able to extend that time by deciding when the freezer cycles and turning the inverter on and off every 3 hours or so in an emergency.
It turns out the inverter had a blown capacitor. That's why the voltage was so low. Most 1500w inverters use around 8w of standby consumption. Hope this helps!
i been curious about this myself. i just bought a high efficiency 3.5CF and 2 100AH batteries for cloudy days. i got 2 Renogy 100W solar panels to push it. its not yet arrived in the mail but i think i possibly may need to double my solar panels, just a hunch there.
Doubling the solar is a good idea. That would make it sustainable for many more days at a time. Thanks for the comment.
Aaaand, his son steals the show! 😂
I know, right! Thanks for the comment.
Just saw your video and what a great timing. I've been thinking of buying a freezer but am still undecided on whether to purchase the 5 cu ft. or the 7. Since it is my two of us I'm leaning towards the 5 cu ft. Seeing that that 7 was so efficient I am hoping that the 5 cu one will be just as much. Gives me a piece of mind that a 100 ah battery ran it that long empty. I have a couple of ecoflow delta max 2000 that I can hook up to and use as an EPS for when we experience a power outage which is frequent in my area. This is good information to know especially when we travel and are gone for several days or weeks. I know that my ecoflow powers my residential fridge for 17 hours by which power returns but the freezer that will have all my expensive meats will be a game changer with how efficient it is. Thanks for sharing.
You're welcome! Also, the freezer will run much longer when it's got food in it. I've heard of you put 1\2 gallon jugs of water at the bottom, it makes a big difference. Thank you for the comment.
I have a similar Freezer and it refuses to run off my Jackery 500 or my Bluetti EB3A. It does run off my DIY solar system that has a 3000 Watt Pure Sine Wave Inverter. You would think 500/600 Watts of power would be overkill to run the Freezer, but nope wont do it. The freezer did come with a caution wont run on solar generators, can you believe that lol.
I'm surprised about the EB3A. It doesn't work even if you have it set to powerlifting?
@@OffGridBasement i didnt try the powerlifting mode i dont think i would use the mode for any reason only because it could case damage.
@@mannyfragoza9652 yes thats why it so good to test now while you can. You will need a lot more power than you realize for everything. With all of your batteries assume 80% when planning
Thx for the great video.
You're welcome! Thanks for the comment.
I want a solar system to run my deep freezer 9 cu ft and am trying to figure out what it would cost. Any idea? This vid was very helpful
I believe you would want 200ah battery, 30A charge controller, 1000w pure sign wave inverter and about 400w of solar panels. You're looking at a minimum of $800. That is just an educated guess. I hope that points you in the right direction!
sorry if you said it and I missed it but what size inverter did you use on this test?
I used a 1500w inverter from ALFFAA.
Good experiment, thanks but how long can it run with a solar power
With a 200w solar panel and ideal sun, I believe you could run the freezer indefinitely.
What size solar setup do you think you would need to keep the battery charged to run the deep freezer indefinitely?
I would double the battery AH and add 400w of solar. I think that would do it nicely.
I'd love to see this redone with frozen food and thawed food. How long do they last before they go bad... plus the aspects of adding different liquids, liquid oxygen, nitrogen, and dry ice... how long will they last before it thaws out because there's an outage.
Another would be about the time needed before you had to restart the freezer to keep the food frozen/cool enough to last long...
Cheers!
Oh ya, what's your protocol/s on battery fires... and any bad products from Amazon, related to creating those same fires... since they love to sell like the other websites... lol
Cheers!
Thank you for the suggestions and the comment.
Turned down to lowest setting-s turns n2 a Frig/super efficient/longer lasting...what temp.setn' did u use?
I used whatever the default was! I don't think I ever adjusted it. Always sits at 0⁰. Thanks for the comment.
Would propane fridge freezer be better bang for the buck?
I personally don't think so. I have enough solar and battery backup to run my freezer. I also wouldn't want to constantly need propane. They are a very good option for RVs. Thanks for the comment.
The big users of power in a refrigerator are the initial cooldown of the machine, and the freezing of content that was bought or harvested fresh.
All you need now is a solar charging system.
Thanks for the info and the comment!
Can you show us how to build connect the 12v 100 battery with the 1500 inverter and how to connect it
Yes. I can create a detailed video on connecting an inverter to the appropriate battery.
Finally you got a mic 🤣
Yes! I think I need to use the dead cat filter in order to not hear me nose breathing so much! hahah!
Yes, you can fill it with food or styrofoam blocks and it will use much less power.
Curious what refrigerant this freezer uses? It should be listed on the data plate. I cant find it that information on Lowes web site.
I don't know anything about refrigerant, but it says "r600a". Hope that helps! Apologies for so long.
So if you add a couple of hundred watt panels and the charge controller this thing will be autonomous?
Yes. Right now I have 1800w of solar and 600ah of capacity. It's overkill and I never need to worry about it. Thanks for the comment.
Hello friend i have 48V solar charger 30A PWM SOLAR CHARGER CHANGER CONTROLLER WHAT PAMEL CAN I USED CAN USED FEW 12PANEL TO CHARGE MY BATTERY
For a 48v configuration I believe you need at least 60v of panels. If you connect four 12v panels in series that should be good enough. Hope this helps. Thanks for the comment.
Thanks ☺☺☺☺ am trying to finsh my project yet done need get better battery but i used what i have for now all love watching video
I have the same freezer you do. I am considering buying a OUKITEL (CN505) 614.4Wh LiFePO4 500W Solar Generator. My freezer when full is pulling about 55wt. Based on your numbers (32 hrs on a 100wh battery...the OUKITEL unit providing 500wh (figuring about 80% realistic capacity) should run my freezer for over 6 days??? (5x32=160hrs) Is my math correct? Or am I missing something...
EDIT: I did just read below where a guy was unable to run his freezer with either his Jackery 500 or my Bluetti EB3A. What's happening there? Are these inverters too weak? (surge capacity?)
If I'm reading this correctly the OUKITEL has 614wh. This freezer was running on a 100AH battery. 100AH = 1280Wh. That would mean your 614Wh solar generator would get about 16 hours of runtime not including the loses from the inverter. Realistically, the power station might get about 12 hours of runtime if it works. Hope this helps!
I have a Bluetti EB3A, but I've never tried to run the Freezer. I really think it depends on the freezer on whether it will run from a Jackery or EB3A. I think you correct in the surge being too much for the solar generators.
I'm just going by the results of the shunt connected to a 100ah battery. I figured you have about half of the storage capacity. That would mean roughly half of the time.
Freeze a cup of water to the top and place a quarter on it and set it inside the freezer. If the quarter drops, you know the power may have been out.
That is genius! That would be great for the people that insist on unplugging the unit to save energy. If the quarter drops, it's been unplugged for too long! Good thinking and thanks for the comment!
Great idea.👍
You can get way better energy star ratings in freezers twice that size and bigger FYI.
Thanks for the info and comment.
Hello. I have a ecoflow delta pro. I'm confused about how long I could run a freezer like this to constantly be freezing ice for an icy breeze. I have a wave 2 and it's dangerous and failing.
The ecoflow delta pro has about 3x the capacity of this 100ah battery.
Ecoflow = 3600wh
Battery in video = 1280wh
I would say you should be able to get at least 80 hours of freezer run time. Hope this helps.
Thanks!!
My freezer seems inefficient. I think I'm going to return it. It's runs at least 80 watts, and is always on even full of Ice
a freezer with less than half its capacity used is showing most use of power- learned that in 70's.. my own freezer is twice as big but the usage is comparable..yet, my freezer has actually frozen at the compressor if run too empty- so I run it with water jugs often times between meat loads. One day I will get a 12 or 24 vdc freezer
I actually have a 2000 watt inverter on a 100 amp battery running with a chinese small charge controller and two 100 watt panels and it is on six months running fine for a fridge and a freezer.. normally holding 40-50 pounds chicken..
no problems
The water jugs is a good idea!
That is the perfect sized system for the application it's powering. Nice work! Thanks for the comment.
@@brotheradam hey I appreciate that info. I'm on here because I'm trying to set up a system to run two small chest freezers on a solar system some of what you just stated.
Can you run the test with freezer full of food to get a realistic evaluation over mseveral days?
I think it may take me awhile to fill this freezer! I would like to do that though. Thanks for the comment.
Awesome
Thanks for the comment.
You should have put some water in the freezer to freeze.
Your energy usage is measured in Wh or KWh.
Thanks for the info and comment.
Information I can use, thanks!
Any time! Thanks for the comment.
You should have brought down freezer temp first, filled freezer, (as in real world power loss ). After cycled off, then start battery test.
I did this test again with those specs. Here is the link: ruclips.net/video/1uY1rRy7wrQ/видео.html
Thanks for the comment.
It was definitely real world for me! I have solar only for electric and this is exactly how it would go for me.
nice
Thanks!
Amazing video but please finish painting your basement!
A basements not a basement if it doesn't look gross! ;-)
Think I messed up I plugged both wires from battery to inverter then plugged freezer…. Help
That sounds correct. What is the problem?
He may not have charged the inverter with a piece of thin wire connected to the battery before plugging in the freezer.@@OffGridBasement
How long can 1 car battery that's 1,000cca run a 600w Ac without solar panels ?
Maybe 18 hours: V x amps = watts. 12 x 900 (running amps) = 10,800 divided by 600= 18 hours. However, doing this would draw your battery down to zero amps which will kill your battery if you do this often enough, even if its a deep cycle battery.
I know you said running watts settled @ 100watts ... But what was the Actual Startup watts ? I heard that actual starting watts can double even triple
That is a good question. I'll need to use a smart plug to capture the startup wattage. I'll try to capture that and let you know!
@@OffGridBasement Thanks
Yes that is always interesting to know
That's the real killer
I run a 155l upright freezer and a 242l fridge only on 240v on a 400ah 24v bank fully off grid here in OZ
Temps between minus 6 Celsius in winter and positive 46 Celsius in summer
I started with a 1200w pure sine wave Giandel inverter
But on the odd times both started up together it would trip the inverter
Both are only about 50/60w running current
Changed to a 2000w model and all runs fine
So definitely something to consider
Cheers
@@OffGridBasement I wrote GE about the specs on that freezer (we have the same Hotpoint model). Their reply:
"I apologize for the wait on this information. Your freezer’s running wattage is 195.5 watts and the surge wattage can be from 2-3 times the running wattage.
I hope you have a wonderful weekend. Thank you for contacting GE Appliances."
That would mean you need 600w minimum surge capacity. Not understanding things electrical...I'm wondering why if the running wattage is 195.5w, why does my power monitor show it's using 50w -60w??
An empty freezer will take a shorter time to get to a constant zero °, so unless everything you fill it with is already below zero ° it will take over 12 hours for it to reach zero °.
Thanks for the info and the comment.
Is it a freezer alone or can it be used as a Fridge too ???????????????????
This is just a freezer. Not able to use as refrigerator.
What is the wattage of the freezer?
The freezer uses about 75w when running. Hope that helps!
You can also chop the battery in 3
I'm not sure I follow you.
Can you do this test with a lead acid battery
Sorry, but I don't have any lead acid batteries to run this test.
@@OffGridBasement the lithium batteries cost a lot of money
Just cut the results in half.
I’m a little older and have had a few freezers . Usually I was told never to run a freezer empty , first off , for what good reason, always at least a 5 gal pail three quarters full , one to see how well the freezer works, second to help maintain the frozen atmosphere, like a cooler or an ice box . In what scenario would it be used empty ?
It shouldn't! I wanted to show the worst case setup. This amount of time should be the LEAST amount of time you would get from a freezer. Most would have already been frozen and probably at least 1/3 full if not more.
Is it ok to use this for 15 cubic deep freezer?
I'm sure it would work fine. The compressor probably doesn't require too much more power. If it's possible to find out what the surge wattage is, that would be best.
that's not a energy style chest freezer. a energy style freezer almost cuts the usage in half. I tested both with my kilowatts meter
You're right. This is a very basic freezer unit. I bought a freezer that I figured the average home owner would purchase. Thanks for the comment and information.
well you should have told people that in your video so they know, its a huge difference, just saying. I also run a 7 cubic ft chest freezer with a external thermostat so it runs as a fridge, great energy save as it opens form the top where warm air goes and its way better insulated than a standard fridge. external thermostats cost 6o bucks. have done this for over 25 years@@OffGridBasement
@@billywray4524Billy, what do you mean by a real energy style chest freezer? Did you mean to type "energy star"?
Thanks
@@prometheusboat sorry yes i meant energy star. tested both huge difference in usage
@billywray4524 thanks a lot Billy
Are you running a pure Sine wave inverter
Yes. The inverter is a pure sign wave. Thanks for the question and comment.
@@OffGridBasement I have a 5000 watt modified and now they are saying it will burn out a fridge or chest type freezer, it takes two batteries to get the 5000 watts, but if you keep something charging the the batteries, it will run ever thing in the house at the same time (110-120 of course) power house but now has me worried to use it, what can you tell me about this modified sign wave inverter
@@randybird9979 I do know that modified sign wave is harder on anything with a motor. You could get a smaller pure sign for just the fridge. I've found a 1500w does the job just fine. Hope this helps.
@@OffGridBasement I been thinking I need to get a pure sinewave , I have used the modified sinewave for fridge, but not much only when electric went off, thanks for the info
I want to build an ice cream tricycle, would I just need a power inverter and a battery to run the freezer?
Yes. A fuse would be a good idea and a way to charge the battery. Thanks for the comment.
what did it use in amps per hour ?
The freezer averages out to use 3.07 amps per hour. Thanks for the comment.
@@OffGridBasement ...thank you !
Imagine a solar panel hooked up to it also during the day to help recharge the battery
I'll be doing a test like this summer.
How much this system cost?
I believe you can get a battery and inverter for around $400 - $450.
Cant get anything cheaper, for a starter like my self made like a 200 us am in Jamaica
Oddly, your 1500w inverter used to drain 19 watts from the battery without AC load, and now with a freezer when compressor is off, it drains only 12.5 wattss from the battery.
It was because the first inverter had a blown capacitor. I believe this one is the replacement. Thanks for the comment.
I'm not sure where I'm going wrong but I couldn't get my 3.5CF to run 12 hours on a 200AH battery.
Is it well insulated?
Q, is that you? Where is Joe, Murr and Sal?
Mine uses. 70 kw per day. But when it is full I can shut the power off and food is frozen for about 7days
I don't think you mean 70kw. That would be a commerical walk in freezer at least!
.70
You had to lay out some serious cash on the system in order to save that $30 yearly electric cost.
It's more for when the power goes out. I don't want to lose the $1000 of meat I have frozen. Thanks for the comment.
It would work better with a voltage regulator
I'm not sure how that would help with this set up.
It will do it, but your killing that battery....
I would think it is killing the inverter more than the battery.
It might need a 2000 watt inverter
A 2k inverter would also work well.
Hilarious 50% of your electric went to the 1500 watt inverter. You probably would have gotten 2 days with a matching inverter. And if you had frozen water jugs you would have probably gotten 4 days
Thanks for the comment and info.
92vac input is a bad thing. You may want to check the input with another meter just to be sure. It'll run but the low input voltage will definitely reduce the longevity of the freezer. Possibly much sooner than you would think, no way to know. Good luck
You're correct. It turns out the inverter had a blown capacitor. ALFFAA sent me a new inverter and it runs at 114v. Thanks for the comment.
Please i brought freezer 219 litter is quickly freezing but in the next 6 or10, hours Ice is not longer what can cause it please
Is the battery out of power? Can you charge it back up? I'm not sure what the problem is.
freeze the ice all day with photo panels then you won't need a battery
Thanks for the advice.
Your mic volume is super low for some reason.
Weird. I can hear my voice just fine in the video. Thanks for the comment.
if you didnt open the freezer all the time and had filled the freezer with food items you could have probably gotten 48 hours plus.
Yes, it would last a lot longer. Thanks for the comment.
Cant find a video of someone running a freezer indefinitely off of solar/battery full time. Im assuming its because you cant
You definitely can. The freezer in the video is powered by my 24v system. 300ah and 1.8k of solar powers it 24/7 with no problem. I plan on doing some things with a 100ah battery and a 180w solar panel soon. Thanks for the comment.
funny when people think their off grid power doesn't cost anything. lol
When i made that comment in the video I was only talking about myself. All of my equipment is 100% paid for. I understand what you are saying, but in my case it was true. If I had a 20 year loan on a whole house system I would never say that. Thanks for the comment.
@@OffGridBasement regardless, you must depreciate your equipment and do the math and you will find that it is the most expensive electricity on earth by a long shot.
