Seeking Advice: Emergency Insulin Refrigeration Solutions for Power Outages in High Heat

[SupportTheSecond]

I have a "solar" generator with 200 W panels that will keep it charged. Would power a small refrigeration unit no problem. As well as be available for other tasks. Not very expensive either.

@SupportTheSecond Thanks for sharing about your solar generator setup. It's a relief to hear that you've got a 200 W panel system that can handle a small fridge without any issues. Plus, the fact that it's not too pricey is definitely a plus.

I've got a few questions about your setup:

Can you share which solar generator model you're using? I'm curious about the specs and how well it performs. I see Costco has something like these on sale right now, could power a smaller fridge I'd guess. https://www.costco.com/jackery-explorer-1500-+-2-100w-solarsaga-panels.product.100982895.html
How does it handle the Arizona heat? I'm guessing that's a big factor in how well it performs.
Any recommendations on a small refrigeration unit that works well with a setup like yours?
Lastly, what other tasks do you usually power with your solar generator? Just trying to get an idea of its versatility.
Really appreciate your input. It's super helpful as I figure out the best setup for our needs.

I have been using the model below, have had it about 18 months and my monthly battery check on it has always been 100% which really surprised me. I will attach the links to the two parts I use for the hardware. Been very happy with it although I have only used it to test with and not long term in hours, but it has very positive reviews and comments. (The one linked below is very similar to the Gooloo 600, but they show the Gooloo 600 not available on Amazon.

FOR SOME REASON THE LINKS ARE NOT SHOWING IN THE POST.

That package you listed from Costco is a good deal. It's got more juice than you need, but I think it's worth it for piece of mind and being able to run things longer between charges if needed.

You shouldn't have trouble running any dorm sized fridge on that, but the lowest cost-per-year should reflect more efficiency/lower power use.

Table top ice makers actually work pretty well/quick. I like ice because its a way of "storing" cold (in a cooler).

Something else to consider is a wireless thermometer to keep an eye on actual temps where the insulin is.

I'm not going to claim that I'm an expert, but for the power source I would go with solar powered batteries and solar panels. You could always start with one battery and one panel and a more batteries as the budget permits. If one battery can be used to power a small fridge, electric cooler, or something similar, and you have several batteries, I think you would be good for the days without sun as well. It won't be as cheap as a gas generator, but the sun is probably not running out of fuel anytime soon and you might not want to rely on gas you have on hand or having to try and get more gas.

As far as a fridge, if it's just for insulin and will be kept indoors I wonder if one of those small office soda refrigerators would be sufficient. They are not very expensive.

@campinginaz Really appreciate you sharing your thoughts on this. The idea of starting with a solar-powered battery and panel and then scaling up as needed seems like a smart approach. It's great to have a setup that's expandable and flexible.

I've got a few things I'm wondering about:

Do you have any specific brands or models for the solar panels and batteries that you think would be a good starting point?
About the small office soda refrigerators – that's a good idea for just storing insulin. Have you used one, or do you know anyone who has? I'm curious about how well they maintain a consistent temperature.
Also, in terms of energy consumption, do you think these small fridges would be efficient enough to run on a solar battery setup without draining too much power?
You're right about the sun not running out of fuel, and it does seem like a more sustainable option in the long run compared to a gas generator.

Thanks again for your input – it's giving me some great avenues to explore!

Hey man, happy to help out in any way I can.

I have a Jackery setup which is a medium quality product with decent pricing. Is there better and more expensive stuff out there.... absolutely. Will this do the job, I believe it will and it won't break the bank as much.

This being said I have only had mine since November of 2022 (they do great black Friday deals!). I have taken it camping to test it out a few times but I have not tested it long term. They do have great reviews online though.

Here is the setup that I have = https://www.jackery.com/products/jackery-solar-generator-300-plus?variant=40238994325591

Here it is on Amazon (often cheaper) = Jackery on Amazon

As far as a refrigerator I won't be as much help.

This is what I have in my office, and while it might be an OK option I would get something better, and maybe get this as a backup option if your primary goes out since it's cheap enough.

Coke Fridge

Here is another cheaper option with great reviews. I don't have any experience though.
Frigidaire

I'm in San Tan Valley if you want to meet up sometime and I can show you the Jackery setup.

I have an automotive 12 volt refrigerator in my overland truck it's 37 qts. temp range is adjustable from -6 to 60 degrees. My 100 AH battery in my truck will last 3 days without re-charging. I would recommend a 100 to 200 watt solar unit to charge a 100 AH battery it should have no problem keeping things cool indefinitely. I have a cheap Alpicool refrigerator cost a couple hundred bucks. I got it five years ago and I was using it everyday for about 2 years with no problem. even sitting inside my SUV in the summer it will maintain 35 to 40 degrees with no problem. I have also kept ice cream frozen for days in it and actually made ice in it too.. All of that even in the Arizona summer heat.

For your use I would set the fridge inside and have the solar charger and battery outside with a good heavy Gage wire coming inside. Don't skimp on the wire coming inside and keep the wires as short as possible too reduce the energy lost to resistance. You could also use the unit if you go hunting or camping.

@Cmoor I like hearing that your automotive 12-volt fridge and how it's been holding up, especially in our Arizona heat. Keeping ice cream frozen in this weather? Now that's impressive! Insulin be stored in a refrigerator at approximately 36°F to 46°F, so sounds like what you have will help with that.

I'm thinking about your suggestions and have a few things I'm curious about:

The Alpicool refrigerator sounds like a solid choice. Any specific model you'd recommend based on your experience?
For the solar setup, do you have any brand or model recommendations for a 100 to 200 watt unit and a 100 AH battery?
About the wiring – totally get your point on not skimping. Any tips on what gauge wire to go for and the best way to set it up for minimal energy loss?
And just out of curiosity, have you faced any maintenance issues or needed any special care for your fridge or solar setup over the years?
Really appreciate you sharing your experience. It's giving me some great ideas on how to keep things cool, plus some extra perks for camping and hunting too.

I have an Alpicool CF35 I run a 12 gauge wire from battery to cooler. Running watts are around 45 but it does not draw that amount full time. Set it up out of direct sun and you should be fine. Renogy makes a 200 watt solar unit with a charge controller then just add whatever type of battery you want to use. If you run one of the 12 /24 volt units you wont need to waste energy converting it with an inverter. Inverters are draining the battery full time even when the fridge is not running. A dc unit will only draw power when the motor in the fridge is actively running. With the Alpicool you can adjust the temp to maintain the temperature you want.

Only maintenance is to clean out the inside when needed and I blew out dust collecting on the evaporator or condenser after 3 years

You should be able to put a system together for under $750.00 depending on what batteries you use.

Fridge around $240
Solar unit around $260
100 AH battery from $150 to $200 or more depending on what kind you get.
Batteries could be wet cell, gas mat or on the expensive side a Lithium.
