Running Brand New 7cu. ft. Deep Freezer with a 12v 100ah LifePO4 Battery!

This UnoWix 12v 100a Lifepo4 Battery is taking the challenge of running a Brand New 7 cu. ft. Deep Freezer fresh out of the box! This is the first time plugging it in, so it was nice and warm. The test is perfect for Seasonal Off Grid Cabin Owners! Let the test begin!
In this video I show just how long a UnoWix 12v 100ah lifepo4 battery can start up and run a 7cu. ft. chest freezer. I used a 1500w off grid inverter, which was probably overkill. There was nothing in the freezer during this test, so the chest freezer efficiency was at it's lowest.

[@devonhallassociates9524]

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.

[@OffGridBasement]

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.

[@ARLGD]

Great analysis! The Segway Portable PowerStation Cube Series seems like a solid choice for outdoor enthusiasts and RV lovers. Its massive capacity, fast recharging, versatile sockets, and waterproof technology make it a reliable power source. Plus, the smart APP control adds convenience. Thanks for sharing your insights!

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.

You should have brought down freezer temp first, filled freezer, (as in real world power loss ). After cycled off, then start battery test.

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

[@ericchang7706]

~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.

[@OffGridBasement]

I'm sure you're correct. Once I get it 1/2 full I will do the test again to see the differences. Thanks for the comment!

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 ?

[@OffGridBasement]

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.

[@OffGridBasement]

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!

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.

[@DAMAGEINC29]

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?

[@OffGridBasement]

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!

[@DAMAGEINC29]

@@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.

[@ilildragon]

Great video, do you happen to know what is the wattage on this freezer chest? Or how many amps does it draw? Thanks.

[@OffGridBasement]

The freezer uses about 70w when it running. At 120v, that would be about .6A

[@rhinogooner]

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?

[@OffGridBasement]

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.

[@angelaereed314]

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.

[@middleway1885]

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!

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!

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.)

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.

How long can 1 car battery that's 1,000cca run a 600w Ac without solar panels ?

[@walterbuller9171]

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 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?)

[@OffGridBasement]

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.

[@OffGridBasement]

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.

[@nomaddavestinyhomes2363]

Mine uses. 70 kw per day. But when it is full I can shut the power off and food is frozen for about 7days

[@OffGridBasement]

I don't think you mean 70kw. That would be a commerical walk in freezer at least!

[@nomaddavestinyhomes2363]

.70

freeze the ice all day with photo panels then you won't need a battery

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.

[@OffGridBasement]

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.

[@joemartinez8819]

Thanks!!

[@joemartinez8819]

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

[@scottbashaw1761]

Would propane fridge freezer be better bang for the buck?

[@OffGridBasement]

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.

[@fargopcguy]

It will do it, but your killing that battery....

[@OffGridBasement]

I would think it is killing the inverter more than the battery.

[@jpatsentertainmentvideos9755]

Is it ok to use this for 15 cubic deep freezer?

[@OffGridBasement]

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.

[@jaspersnow4928]

It would work better with a voltage regulator

[@OffGridBasement]

I'm not sure how that would help with this set up.

[@dougofford6567]

You're welcome! Thanks for the comment.

[@saheedmustabiola4102]

What is the wattage of the freezer?

[@OffGridBasement]

The freezer uses about 75w when running. Hope that helps!

[@jaspersnow4928]

It might need a 2000 watt inverter

[@OffGridBasement]

A 2k inverter would also work well.

[@jaspersnow4928]

You can also chop the battery in 3

[@OffGridBasement]

I'm not sure I follow you.

[@brotheradam]

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

[@brotheradam]

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

[@OffGridBasement]

The water jugs is a good idea!

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!

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

[@zippy2641]

@@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??

@@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.

Cant find a video of someone running a freezer indefinitely off of solar/battery full time. Im assuming its because you cant

[@OffGridBasement]

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.

[@wg6215]

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

[@OffGridBasement]

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.

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 ?

[@OffGridBasement]

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.
