Can you put a all in one inverter inside of large stand up fridge or freezer for installation in garage? It is cold here.

I order the new 6000XP all in one and the EG4 LifePower4 Lithium Battery 48v want to put it in my garage. Because of the cold temp in my area ( it go blow 0 in winter) I was thinking to put all in a one big stand up freezer to keep out the cold.
My question is can you put a all in one inverter like that in a close and sealed space like a freezer of a refrigerator. I see people on YouTube do it with batteries but can’t find any info for the all in one inverters.
 
I am not familiar with that inverter but inverters and controllers put off a lot of heat and need to be cooled down. So putting one in an enclosed space would probably damage it.
 
You would need about R12-R16 insulation to give you a 40ºF temperature delta. You might do a little better with some sheets of rigid insulation than a freezer. How would you propose to mount the equipment inside? Any penetrations to the frame of the freezer would likely reduce the effectiveness significantly.

2" rigid foam is R8.6 if you use the mylar coated stuff for reference.
 
In my experience it is going to get way too hot. Maybe not in the winter, but spring and summer here would bake it to death.
 
I have a 5'x6' room in my detached uninsulated garage.

The room has a 10,000 btu Air-conditioner, 5000 btu heater and is built with R16 rockwool insulation, 5/8" drywall.

My issue is cooling, the heater hasn't turned on this year.

Currently the Outside low temperature is 30 f and my solar room hasn't dropped below 60f. If I don't open the door during the day (high temp 60 f) the Air-conditioner still turns on (set at 80 f)

I was going to ask you some questions in my thread about storage for batteries and equipment as we are in a tiny house that's on the upper limit of sqft to be called a tiny house. 24x24 without practical space really for batteries and my wife isn't too happy about seeing the solar equipment in there because the entire house is v-groove interior and she doesn't want to ugly it up as she put it. lol so I been thinking about a small shed to house the equipment. In South Georgia the heat during the summer is a concern but I thought a very small window unit could correct it or maybe solar exhaust fans. I'd love to see your set up.
 
Sadly I know the type.
You can’t help people who don’t want it.
No sir you can't as I have learned. My biological father was both, my sister has been both but finally got help after hitting rock bottom. I have had enough of drugs and alcohol problems that were not mine to deal with. I've had friends that were my senior my whole life. I learn from them and they value me as I do them without motives. I just don't fit in with people my age and I'm good with that. The down side is my friends are 15 to 20 years older than me. In my 30's most of my friends were 50 to 90 years old. In other words I've lost most of them but I cherished them all. Some of them have introduced me as their adopted grandson to people their age. Yes sir I loved them as my adopted grands as well.

So you need to show power for permit or inspection? If not, put them in a Rubbermaid style shed with extra insulation outside, If you do, get a tiny (~1000W) inverter and AGM battery bank for inspection and put the real equipment in afterwards.
 
32 – 113°F (0 – 45°C) I mean, they give off heat when running.... Do you plan to run it full time? I honestly think you will be fine (Inverter) I guess you could make a larger box around it to minimize the cold......... batteries you may want to enclose somehow to trap heat

I work in the Server Farm industry, and if money was no object, we would be almost freezing them to control CPU temp
