I hold a master's degree in electrical engineering specializing in electronics; a simulated sine-wave is more than sufficient for 99% of today's home electronics. Power supplies are designed to support a varying range of voltage inputs, allowing a single supply to be used across most of the world. Therefore, they can easily account for subtle variations in voltages from a simulated wave.

I would be shocked to see a Sony device fail because it ran on a simulated sine wave or to have a warranty denied because of it, unless they specifically state not to use one.

This are good overviews:

I'm curious if you just unplugged the TV from the simulated battery backup device and hid the battery backup device in the other room if they would have honored the warranty?

FWIW, I have the earlier version of this UPS, GX1325U, and was able to get replacement batteries for $14+SH & tax...

Is simulated sine wave fine for 3 mini PCs running in a proxmox cluster along with a couple switches, router, and access point?

Have this unit for 8yrs, just replaced the batteries for $50. The problem is not with the unit but getting one that is new. A month ago I bought this and had it shipped to home, box very damaged and unit was obviously a return. I had a second one shipped to the store and the same thing. I dont have "expensive" electronics. The only issue I've ever noticed is when I ran the garage door opener, it ran but sounded odd when running. I read that the simulated sine wave affects motorized devices.
That is the down side to Costco's excellent return policy. The returns just get resold.

I guess YMMV with the quality of these. I've owned 3 and every single one has had a problem esp when the batteries start to die. In my main unit which powers my main PC, monitors, etc. after maybe 2 years, I was getting an E21 error which indicates a battery output short. I replaced them with brand new Cyberpower batteries, and same error so the power board likely died and I had to toss the entire thing. In my unit downstairs which powers my NAS, I also had to replace the batteries on those when it start beeping every time there was a surge and it could not hold any charge on the battery backup. After replacing those, the power button LED and display completely fails to turn on so looks like it took out something else in the process, but functionally it seems to be working. A replacement unit I got once to RMA a DOA unit died altogether after about a year (looks like they sent a refurb, it was not new).

I'm sure there are many success stories, but I haven't had any good luck with these. When they do work, they're fine, but batteries will ultimately die and many times it will take something else out with it. In all three cases, it was this very same UPS, the 1500VA 900W. Do yourself a favor and pay a bit more to get something more enterprise grade from a company like Tripp Lite. I'd probably even vouch for APC pure sine wave over these at this point.

Are you in my homelab rn?
I have 2 cyber power 1500 UPS and split proxmox on 1 and router/poe ap/ switch/modem on the other. The cluster will eat the battery quick depending on load. The networking gear will go 40-min in my use case. Proxmox cluster is <10min

I'd be careful about simulated sine wave it'll definitely mess up a big screen TV when the power goes out it caused by oled Sony 50 inch TV power supply to fail and when the technician came out to fix it they would not warranty it because of this simulated battery backups are good for certain things but not for sensitive electronics

Whats interresting is my same unit has no problem running my router, modem, surveillance, PC, or monitor, plugged into it. However it will not run or recharge off my generator. THC is most likely the issue, yet everything else in my house runs fine on the generators power.

They probably mean THD (Total Harmonic Distortion)

Too bad I don't have a Costco membership. I've been looking to buy a big UPS for a while.
