I just purchased a smart thermostat that will turn the freezer on when it reaches 20 and off when it gets to zero. This should conserve a lot of power, and still keep things safely below freezing.
I have a similar setup. A 100 ah LifePo4 battery, 1000 watt inverter, 20 amp pwm charge controller, 2 ea 100 watt solar panels. My garage frig has a 50/50 run/off and draws 70-80 watts off the inverter. Inverter is pure sine wave and draws 13 watts continuously. I started out using one panel and it couldn’t keep up. Two panels will run my system indefinitely as long as I have good sun for 6 to 8 hours.
I'm impressed with that freezer. For it to stay below 10 degrees in that hot garage is awesome. I bet more battery power was used on the inverter's parasitic draw than what the freezer actually used.
Now remember: Once you fill that freezer up, the efficiency will increase alot, decreasing your power draw. and ofcourse colder months will help out the efficiency even more.
Yes, kinda why I did it this way. I wanted a worse case scenario, but I’m doing another test right now with the freezer “full” and a 200 watt panel helping out to see how long it will run. Be posted soon
Great content, I'm in the process of hooking up a 200 ah Timeusb LifePo4 battery I am sure that it will be much better then the AGM batteries that I have been running 😎😎
Yup! But that’s why I decided to run the test this way…basically this is worst case scenario and the hardest for the battery. I’m building another unit and going to test with a filler freezer and a 200watt solar panel hooked up. 👍🏻
WOW! What else can I say! I am definitively buying one of those batteries as soon as I can, it will be soo interesting to see hpw that small system behaves when you add the solar panels and at the same time you have the freezer connected. I do have one question, does the Fridge you have in the garage have the same power consumption as that freezer? :) Great Work!!!
Excellent review .I’m not sure but if you isolate the freezer with some playbook or others materials outside maybe could last longer the charge of the battery .thanks for the information .I think every person would need to have a system like this in case of an emergency .

Yes, exactly. That’s kinda why I ran the test this way so I could get a “worst case” scenario. So hopefully, if I do ever have to use this setup in a blackout situation the freezer will be more full and I’ll get longer run time👍🏻😃
That video is soon to come. Bug this is a big battery and I only gave a 200 at panel. So honestly, would take days to fully charge this battery without any draw on it.
True. And for this “test” I wanted it empty to give kind of a “worst case” scenario. I put out a 2nd video with the freezer more full and a 200 watt solar panel as well. 👍🏻
this fridge is pricy, but can work as refrige . others you need external thermostat it plugs into. but be carefull the cheap freezers are china brands they work in a narrow range of temps dont like cold some need 50 f also don't like hot so they are not garage ready. ge Hotpoint and several familiar names are ok too. read owners manual some are even marked garage ready. like to see how long extra if even 100 watt panel. also a full freezer will use less also where the freezer is located if you keep the garage door open and sun hits it will use more power i sugest any location sun might hit a freezer never good but buy a white one to reflect heat away

Great results on an empty freezer. It will be a lot more efficient on power when it is full.
👍🏻👍🏻

Holy buckets I watched this one year to the date. Building something like this RIGHT now myself.
😂👍🏻👍🏻
Hello Brian🙋🏻♀️I was wondering how this freezer is holding up?
Thank you for such a great review of this freezer🙏🏼🕊️
Hi! It’s holding up great. It didn’t skip a beat keeping things completely frozen out in the garage in the crazy hot Texas summer we just had.
Great info! In an emergency situation you can use the freezer to make ice blocks and then use those to chill all kinds of food in coolers.
Thanks👍🏻👍🏻

That’s what I’m thinking to.

excellent project results. if you hooked up solar you could prob run in for weeks maybe longer
I’ll be doing that test here very soon!
Not to mention, if the freezer had been full, it would have lasted a lot longer as well, since the food provides a ton of thermal mass to the system.

Thank you 👍🏻
Your freezer will use less power once it’s full so you will be able to go longer between charges, I’m guessing at least another day.
Yup! But that’s why I decided to run the test this way…basically this is worst case scenario and the hardest for the battery. I’m building another unit and going to test with a filler freezer and a 200watt solar panel hooked up. 👍🏻
If you add a cheap solar setup to it you could run that all the time from it and not worry about power outages. Have fun stay safe.
Yessir. That will be the next video👍🏻👍🏻
would be nice to see with 100watts solar panel what it look like!
Will be doing a video on that👍🏻
WOW! What else can I say! I am definitively buying one of those batteries as soon as I can, it will be soo interesting to see hpw that small system behaves when you add the solar panels and at the same time you have the freezer connected.
I do have one question, does the Fridge you have in the garage have the same power consumption as that freezer? :) Great Work!!!
Thanks David. No, the fridge pulls MUCH more watts than this freezer.

Super helpful! Thanks for doing this test.

Thank you👍🏻
battery would have lasted longer if the freezer was full, it takes more power to keep an empty freezer cold than it does to keep a full one cold
Yes, exactly. That’s kinda why I ran the test this way so I could get a “worst case” scenario. So hopefully, if I do ever have to use this setup in a blackout situation the freezer will be more full and I’ll get longer run time👍🏻😃
The freezer will use less power to keep cold once it is full and the food is frozen.
Exactly👍🏻 this was done this way to make it as hard asnpossible
Can you list the equipment of the solar in your video description. I recognise the charge controller but not the inverter.
Everything I used in the description on this video. Check it out
th-cam.com/video/bUpOtj_3N2U/w-d-xo.html
What type of battery did you use for this?
It’s a 200ah REDODO 12.8 lifepo4 battery
If you started the test with the freezer full of frozen items, how long would the battery last?
That will be the next video with a new setup and inverter. I ran the test on this video to show “worst case” scenario.
is that 2 water heaters in the back round?
Yes
How long will it take to charge using your panels?
That video is soon to come. Bug this is a big battery and I only gave a 200 at panel. So honestly, would take days to fully charge this battery without any draw on it.
How do you recharge the battery now that you ran it down? Solar? Battery charger?
I used a battery charger. Not exactly “off grid” but it would take a week to recharge this with my current 120 watt solar panel.
What brand inverter are you using?
This was an Ampeak inverter. I do t recommend it though. It’s very loud even at idle
But it gets the job done. I've bought inverters in the past and best i got was 3 hours. How many watts is the inverter?
It could have been a lot longer if the freezer was full ,,they tent to hold their temp much longer when full..
True. And for this “test” I wanted it empty to give kind of a “worst case” scenario. I put out a 2nd video with the freezer more full and a 200 watt solar panel as well. 👍🏻
What is your inverter information
What are you wanting to know? This one is an Ampeak 1200 pure sine inverter.
It'll probably last even longer once you've got that freezer nice and filled with frozen stuff
Absolutely. I wanted to see how this would do in a worst case scenario👍🏻
I was expecting it to last 7 days on that battery. Maybe if it was full of frozen food and some water bottles.
Yes. Would have helped if it was full, but I wanted to show worst case scenario.
why do you have two water heaters? how many people live in your house?
I don’t know, didn’t build this house
this fridge is pricy, but can work as refrige . others you need external thermostat it plugs into. but be carefull the cheap freezers are china brands they work in a narrow range of temps dont like cold some need 50 f also don't like hot so they are not garage ready. ge Hotpoint and several familiar names are ok too. read owners manual some are even marked garage ready.
like to see how long extra if even 100 watt panel. also a full freezer will use less also where the freezer is located if you keep the garage door open and sun hits it will use more power i sugest any location sun might hit a freezer never good but buy a white one to reflect heat away
👍🏻👍🏻
Pretty impressive
👍🏻👍🏻
That freezer is how many watts?
Avg 60 watts. I’ve never seen it get above 75 even on startup
This garage is different!
This is the garage. My other is my “shop”😉😉
freezer wattage?
Good info
👍🏻👍🏻
What's the name of the freezer r the website. Thank you

The battery is really mad ..
Just got your video If you put 500 watts of solar with that battery I don't believe it would ever run down
It shouldn’t, for sure👍🏻
freezer..it's a freezer
Thanks
This is so weird #brianwatersoutdoors I watched this liked it commented like ten times n now it’s all gone
Not sure why🤷🏻♂️🤷🏻♂️
