I'm asking here as well since there's a higher concentration of electrical engineers who would know these things.

I've been desperately searching for a good and affordable UPS solution for a home dialysis machine for my father in law (FIL). There's been several power outages due to storms where he lives and he's lost all blood in the machine on one occassion.

I've created a reddit post [1] as well with more details. But to summarize we're looking for a UPS solution with a power rating greater than 2000VA that can last upto 90 minutes. So far we've settled on APC SmartUPS products since they provide a 4ms switching time which I expect to be a good. The products cost around $4000.

Any additional info would be much appreciated! Any better UPS out there more suitable for medical equipment? Any cheaper UPS units other there with the similar quality to APC?
