UPS’s monitor the frequency to ensure the power is clean, looking for 60Hz. Powerwalls put out a higher frequency when they are fully charged and I believe also when solar is producing. It ramps up to 65Hz, which most lower end UPS see as an issue. I ended up getting rid of all my CyberPower and replaced with Eaton and haven’t had an issue since.

I believe you have some misconceptions about how health insurance in this country works. I recommend taking a glance at this book.
I used white privacy sail shade type material and added a reflective shade on top .. ambient air is still going to be a problem .. at amazon they have similar products but chose this because of the reviews
I also tried the magic mirror. Ideally I’d like the power flow screen too. Easiest way I’ve been able to do it is install and android emulator on my PC and install the Tesla App on it.
I mostly use computer monitors but still don’t want to break down and mount a small PC monitor somewhere in the house on a wall.
Or you can install something like this in your electrical box .

It will give you all in (from grid , from solar ) and all usage so you can find what is using most energy and adjust it accordingly
I'd recommend buying one of these and testing out each appliance.
2.5kw seems very high. Tesla 1.5 day mark might not have taken into account all the appliances you have. Your AV equipment closet might have more of a phantom draw then you think. (I installed a smart outlet onto a power strip for my AV gear. On idle it uses 3 watts of power versus 70)
Make sure to let it run for 12 hours or a whole day to see your figures. The appliances will use more power on initial startup when plugged in.

I just bought a plain old 1500 watt pure sine wave inverter at Frys. If you plan to power something with a motor (ie, a refrigerator) you'll need pure sine wave. Modified sign wave inverters are cheaper and are ok for electronics but anything with a motor or compressor needs pure sine wave. Something like this:

I don't know how Tesla Model 3 works, but the Volt has a 12v battery in the trunk that starts the car. While the car is running, the 12v is charged by the high voltage battery and/or gas generator via an integrated 1500 watt charger. The above inverter hooks into the 12V battery.
Does that help?
