Thank you everyone!

Good point about allowing for theoretical versus usable capacity. I built in a 20% reduction (i.e when I say a 2kwh pack, it is theoretically 2.4kh) in my calculations to give me a buffer but, I hadn't thought about not wanting to completely discharge the pack, although, I guess that would depend on what's in my fridge at the time

How can I determine if my fridge has this new inverter+compressor mode? I looked through all the documents available online and didn't see anything about it but, it is entirely feasible I didn't recognize it if it was spelled out.

So if I have a regular compressor, I am seeing suggestions between 3x to 7x. I'm guessing that each person has a different point of view based on their experience.

What number should I use to multiplying by 3-7?. For ex. the fridge specs say max load is 864w, does this mean I need to do 7x 864w? This would mean I need an inverter with surge capacity of of 6000w. Or could that number be taking a number of other systems into account, and is the peak number recorded so far (560w) more reasonable?

If I plug and unplug my fridge into my energy monitor a number of times, let's go with 10, would this help me to more precisely pinpoint what I need?. For example, if I unplugged my fridge and opened the fridge and freezer doors for a couple of minutes, then plug it back in, let it get the temp in both compartments back up to normal, then rinsed and repeated 10 times. Would this cause the compressor to kick on 10 times, and I can simply take the highest spike recorded as a reasonable baseline?

I guess that would also mean I need all my fuses and wiring to be able to handle 50A. Lol, I just bought 40amp relays.
